The flashlight market is what business analysts and marketing strategists call a vertical one, with products designed and adapted for a specific use-case and consumer demographic. Basically design and market a product that lights stuff up. For decades, a flashlight was a tube-shaped, cylindrical device, and that was that. If it ain't broke, don\u2019t fix it, right? However, in recent years, we\u2019ve started to see variations on that theme, with light designs taking on a more \u2018angular\u2019 form factor. Parallelogram, rectangle, what have you. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I\u2019ve reviewed the Nitecore TM12K, NEXTORCH TA31, Streamlight Stinger 2020, Fenix E03R v2 to name a few, and more manufacturers are throwing their \u2018non-round\u2019 flashlights into the mix. Now Speras has one\u2026the U2\/U2T. This one\u2019s fresh out of Kickstarter, a project introduced in December 2023 and quickly gained a lot of ground. Speras put a lot of planning and bran cells into this one, and I think it might just be the most versatile portable illumination tool available currently with lots of mounting and switching options. I dig multipurpose flashlights, so let\u2019s dig in.<\/p>\n\n\n\n<h4 id=\"package-quality\" class=\"wp-block-heading\">What's in the package<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Speras U2T comes in a nice, retailable package (even though I\u2019ve never seen these for sale in stores here), so there\u2019s graphics and feature blurbs everywhere, front and back. Here\u2019s what\u2019s inside:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Speras U2 flashlight<\/li>\n\n\n\n<li>Instruction guide<\/li>\n\n\n\n<li>O-rings<\/li>\n\n\n\n<li>Lanyard<\/li>\n\n\n\n<li>USB C charging cable<\/li>\n\n\n\n<li>BM2 bicycle handlebar mount (optional)<\/li>\n\n\n\n<li>WK01 wireless remote (optional)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>This is a ready to run kit<\/strong>, and my tester included the <strong>optional WK01 wireless remote<\/strong> (Speras sent after receiving the tester) and BM2 bike mount. This ups the versatility factor a lot since now the U2T can go on bike duty, or clip to a mount, mast, tripod, etc and be controlled remotely with the remote. Neat! The bike mount also included a 1.5 mm allen wrench and 4 hex head screws for securing the quick-release mount. I appreciated the extra screw when you invariably lose one. You get lots of output out of the box, but it would be wise to fully charge the battery before use for maximum output.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" data-id=\"265900\" src=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-1-1024x682.jpg\" alt=\"Speras U2T package front\" class=\"wp-image-265900\" srcset=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-1-1024x682.jpg 1024w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-1-300x200.jpg 300w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-1-768x512.jpg 768w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-1-1536x1024.jpg 1536w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-1-150x100.jpg 150w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-1.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-2.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" data-id=\"265901\" src=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-2-1024x682.jpg\" alt=\"Speras U2T package rear\" class=\"wp-image-265901\" srcset=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-2-1024x682.jpg 1024w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-2-300x200.jpg 300w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-2-768x512.jpg 768w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-2-1536x1024.jpg 1536w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-2-150x100.jpg 150w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-package-2.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-accessories.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" data-id=\"265899\" src=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-accessories-1024x682.jpg\" alt=\"Speras U2T accessories\" class=\"wp-image-265899\" srcset=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-accessories-1024x682.jpg 1024w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-accessories-300x200.jpg 300w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-accessories-768x512.jpg 768w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-accessories-1536x1024.jpg 1536w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-accessories-150x100.jpg 150w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-accessories.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n<\/figure>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"inherit-container-width wp-block-group groupblock has-border-color has-ast-global-color-1-border-color is-layout-constrained wp-container-core-group-is-layout-c1e7e091 wp-block-group-is-layout-constrained\" style=\"border-width:2px;border-radius:15px;margin-top:var(--wp--preset--spacing--30);margin-bottom:var(--wp--preset--spacing--30);padding-top:var(--wp--preset--spacing--40);padding-right:var(--wp--preset--spacing--40);padding-bottom:var(--wp--preset--spacing--40);padding-left:var(--wp--preset--spacing--40)\"><div class=\"wp-block-group__inner-container\">\n<figure class=\"wp-block-image aligncenter size-full is-resized review-icon\"><img loading=\"lazy\" decoding=\"async\" width=\"128\" height=\"128\" src=\"https:\/\/1lumen.com\/wp-content\/uploads\/icon-review-2-quality.png\" alt=\"icon review 2 quality\" class=\"wp-image-274034\" style=\"width:40px\" srcset=\"https:\/\/1lumen.com\/wp-content\/uploads\/icon-review-2-quality.png 128w, https:\/\/1lumen.com\/wp-content\/uploads\/icon-review-2-quality-96x96.png 96w\" sizes=\"auto, (max-width: 128px) 100vw, 128px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"quality\">Flashlight in use, Build Quality, and Warranty<\/h3>\n<\/div><\/div>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Speras\u2019 goals with the U2T were clear: To make a <strong>true sport utility flashlight<\/strong>, a multi-role lighting tool that can wear a lot of hats and do a lot of things. The U2T is designed to be as compact as possible while maintaining high output. <strong>First off, it\u2019s not round, but rectangular.<\/strong> The design is identical in execution to the Nitecore TM12K and I actually like this form factor. It fits well in the palm, and the host is sized right to fit most hands. <strong>I have big hands, and the U2T felt like a smaller light than it is<\/strong>, even smaller than the Nitecore TM12K. While the shape took some getting used to handling-wise, after a while, it feels nice and natural in the hand, and I found the edge-mounted e-switch and rear clicky easy to reach in all grip positions. There\u2019s no knurling per-se, but Speras machined in grooves and ridges where they felt they were needed.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For carry and retention, the U2T can be pocket carried, but even though Speras did a good job with the form factor, <strong>it\u2019s a bit too big and heavy for regular EDC<\/strong>, but would fit fine in cargo pockets or clipped to a pack, belt, or turnout with the detachable dial-position clip. You get bezel up or down retention, but you need a 1.5 mm hex allen wrench or hex bit to remove the 2 screws securing the clip (included if you get the optional BM2 mount kit).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The BM2 mount is optional and adds lots of versatility<\/strong>. The mount has a quick-release shoe that\u2019s secured to the opposite side of the light with 3 included screws. Once the mount is installed, the light can be slid onto the BM2 mount. <strong>The mount is on a swivel that can pivot left or right about 45 degrees<\/strong>, and is secured to bike handlebars using a cinch strap which works sort of like a hose clamp. <strong>Rotate the plastic nut clockwise to tighten the strap, reverse it to loosen<\/strong>. The mount has a soft rubber pad on the gripping surface for traction to help hold it steady and prevent damage to the hadelbar\u2019s finish.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For switching, you have options. <strong>There\u2019s a single e-switich on one edge. This \u2018T\u2019 version adds a rear tail forward clicky for momentary use<\/strong>. It\u2019s a multidirectional switch that can be pressed on the sides or in the middle.<strong> Pressing the sides activates instant strobe<\/strong>, and half-press or fully clicking activates either momentary or constant-in Turbo. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Speras makes a wired remote, but the ace in the hole for the U2T is the <strong>wireless remote control.<\/strong> <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The kit included the <strong>Speras WK01 wireless remote<\/strong> and USB C receiver\/antenna. It looks like a wireless key fob with 3 buttons labeled A, B, C. More on that in the UI overview. The remote can control the U2T from <strong>up to 15 meters away<\/strong>. Obviously, a wireless remote adds an absolute ton of versatility for hands-free operation. I found it very handy for turning the light on as an area light from a distance to light up a dark room, or lighting up a tent without reaching for the light (if I had a dollar for every time I wish I had that feature I could buy a U2T). <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a bike light or worklight, that would also be great since <strong>you wouldn\u2019t have to take your hands off your work\/bike to change lighting modes or turn the light on\/off<\/strong>. Way to go Speras! Opposite the switch is the USB C charge interface. It\u2019s sealed with a rubber cover that fits flush with the host and makes a tight, snag-free seal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Build quality for the U2T, like all my Speras lights, is great. Nice and tidy on the machining, fit, and finish. I didn\u2019t notice any issues with ill-fitting parts or other anomalies. <strong>Overall, this is a very well-built light. It\u2019s competitively priced for what it is<\/strong>. With optional bike mount, wireless remote, and gradient color, it\u2019s coming in around $80 to $110 US, which isn\u2019t at all unreasonable. The light is milled from the typical 6061-T6 aluminum alloy. It\u2019s blemish-free and there\u2019s no sharp edges anywhere on this light, which I expect for a holster-ready light. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The finish comes in either solid black, or a green\/black gradient finish. It\u2019s type III HA hard anodizing, and it\u2019s also well done. It\u2019s a semi-gloss finish and not super-grippy, but feels high quality. The light is sealed up tight, and Speras gives it an IP66 rating, good for temporary immersion and the worst rainstorms Mother Nature can muster.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the warranty, from Speras.com: <em>1.

aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The LED choice for the Speras U2T is on point in the <strong>Luminus SST40<\/strong>. While everyone seems to gravitate to the SFT-40-W these days, and rightfully so, the elder statesman SST40 is still entirely relevant even in 2024. While it\u2019s not fancy with high CRI or pleasant tints, it has a low vF, is efficient at moderate power outputs, and can get really bright if driven hard. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The U2T uses 3 of these on a single DTP copper MCPCB for maximum thermal efficiency. They sit in a 3 cup SMO reflector with the 3 LEDs in a row, which should help even out the beam and give a nice light dispersion. <strong>It\u2019s capped by an AR coated mineral glass lens<\/strong>. There\u2019s minimal bezel protecting the lens though. The beam is really floody, and there is a bit of a hotspot so you get some beam distance that\u2019s usable out to 200 meters. Overall, an excellent general purpose beam, and one that can be useful on a bike. However, while the U2T beam is adapted slightly for bike use, a dedicated bike light would probably be better since the U2T does have glare up top that could be distracting to motorists, other cyclists, or pedestrians.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Spectral measurements:&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I used the Opple Lightmaster Pro to measure the flashlight at 1 meter from the sensor.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-border-color has-ast-global-color-2-border-color\" style=\"border-width:1px\"><thead><tr><th>Mode:<\/th><th>CCT:<\/th><th>CRI Ra:<\/th><th>duv<\/th><\/tr><\/thead><tbody><tr><td>Turbo<\/td><td>5455K<\/td><td>60.2<\/td><td>0.0132<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The cooler CCTs of SST40 are known to shift green and +duv, so no surprise here! In person it looks better than the reading suggests, but on Low mode, it\u2019s noticeably green, but not as bad as a CW SST20 or LH351D.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images

The U2T probably has a buck driver for fully regulated output. These are superior to the cheaper FET or linear drivers since output isn\u2019t dependent on battery voltage until LVP kicks in, so you get constant output that doesn\u2019t drop as the battery discharges.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The UI is commensurate for a light like this, a dead simple 5-mode affair with nicely spaced modes plus two blinkies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Available modes:&nbsp;<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Eco, Low, Medium, High, Turbo<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Available blinky modes:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Strobe, SOS<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>From OFF:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Press and hold side switch: Turns on in last used mode<\/li>\n\n\n\n<li>Fully click rear switch: Turns on in Turbo<\/li>\n\n\n\n<li>Half-press rear switch: Momentary Turbo<\/li>\n\n\n\n<li>Double click side switch: Strobe.

It doesn\u2019t require a learning curve and incorporates well-spaced modes. Turbo isn\u2019t a separate function and part of the main modes, which I happen to like, and Turbo and Strobe can be called up instantly with the rear clicky switch. While user-preference, and if square lights are your thing, I wouldn\u2019t dissuade someone from using the U2T for duty or tactical applications since the rear switch affords instant access to \u2018tactical\u2019 modes.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"inherit-container-width wp-block-group groupblock has-border-color has-ast-global-color-1-border-color is-layout-constrained wp-container-core-group-is-layout-c1e7e091 wp-block-group-is-layout-constrained\" style=\"border-width:2px;border-radius:15px;margin-top:var(--wp--preset--spacing--30);margin-bottom:var(--wp--preset--spacing--30);padding-top:var(--wp--preset--spacing--40);padding-right:var(--wp--preset--spacing--40);padding-bottom:var(--wp--preset--spacing--40);padding-left:var(--wp--preset--spacing--40)\"><div class=\"wp-block-group__inner-container\">\n<figure class=\"wp-block-image aligncenter size-full is-resized review-icon\"><img loading=\"lazy\" decoding=\"async\" width=\"128\" height=\"128\" src=\"https:\/\/1lumen.com\/wp-content\/uploads\/icon-review-6-battery.png\" alt=\"icon review 6 battery\" class=\"wp-image-274048\" style=\"width:40px\" srcset=\"https:\/\/1lumen.com\/wp-content\/uploads\/icon-review-6-battery.png 128w, https:\/\/1lumen.com\/wp-content\/uploads\/icon-review-6-battery-96x96.png 96w\" sizes=\"auto, (max-width: 128px) 100vw, 128px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"batteries\">Charging and batteries<\/h3>\n<\/div><\/div>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The U2T contains two 18650 li-ion batteries inside the rectangular housing. These are in parallel, and the total capacity is 6400 mAh, so each cell is roughly 3200 mAh. Not surprisingly, <strong>these cells are integrated and cannot be removed<\/strong> (at least not destructively), so when they go flat, you either send the U2T to the recyclers in the sky, use it as a paperweight, or gift it to someone you don\u2019t like. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The charging is <strong>USB type C<\/strong>, and Speras says it\u2019s good up to 15 watts (5 volts 3 amps). It\u2019s also a power bank, and can run off a C to C cable and charge your devices up to the same 15 watts. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Speras includes a <strong>USB OTG adapter<\/strong> (on the go) dongle which is a C to A adapter that accepts a USB A to C cable. It\u2019s made of aluminum and has a tiny lanyard on it. I\u2019d still consider this an emergency power supply since fully charging most modern mobile phones with a 4.2 Ah battery off the U2T would mostly drain the battery. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the Hidance USB C tester I was seeing around 17 watts and on the Ruideng AT35 USB A tester I was getting around the same. Charging up some other flashlights and devices on the power bank I was getting between 8 to 13 watts. Speras says the battery should charge in about 2 hours, and after a runtime, my USB meter showed charge termination after 2 hours 3 minutes to add 5378 mAh.&nbsp;<\/p>\n\n\n\n<figure

We see nicely regulated output across all of the (measured) runtimes here. While I hit the output specs for all modes except Turbo, these all look good. On High, you\u2019re getting better than 1000 Lumens for over 2 minutes, and Turbo delivers better than 2000 Lumens for almost 60 seconds. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After 180 seconds though, <strong>High and Turbo are down to around 600 Lumens<\/strong>, where they camp until a step down to around 150 Lumens for a short time before shutting down. Medium gives around 500 Lumens for nearly 7 hours before stepping down to around 100 Lumens, then shutting down. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Temperatures were kept well in check, never exceeding 55 C<\/strong>, and the host was comfortable to hold even after prolonged Turbo use. The conservative thermal limit might be the reason for the unimpressive sustained output for a triple LED light, but I get the design limits heat sinking and thermal capacity. Turbo can be recalled (any mode really) after the first step down. For LVP, I didn\u2019t notice any visual notifications, other than the blinking switch LED. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the comparison testing, I grabbed some other triple or quad LED lights. You can see that the U2T holds its own on High, but falls behind the others in sustained output.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-1 wp-block-gallery-7 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-10-minutes.png\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"800\" data-id=\"265931\" src=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-10-minutes.png\" alt=\"speras u2t runtime comparison 10 minutes\" class=\"wp-image-265931\" srcset=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-10-minutes.png 800w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-10-minutes-300x300.png 300w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-10-minutes-768x768.png 768w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-10-minutes-96x96.png 96w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-10-minutes-150x150.png 150w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-60-minutes.png\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"800\" data-id=\"265932\" src=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-60-minutes.png\" alt=\"speras u2t runtime comparison 60 minutes\" class=\"wp-image-265932\" srcset=\"https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-60-minutes.png 800w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-60-minutes-300x300.png 300w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-60-minutes-768x768.png 768w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-60-minutes-96x96.png 96w, https:\/\/1lumen.com\/wp-content\/uploads\/speras-u2t-runtime-comparison-60-minutes-150x150.png 150w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/figure>\n<\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Peak beam intensity and beam distance measurements<\/h3>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><mark style=\"background-color:rgba(0, 0, 0, 0);color:#0000ff\" class=\"has-inline-color\">About Peak beam intensity: Understanding ANSI FL1 Standard<\/mark><\/summary>\n<p class=\"has-border-color wp-block-paragraph\" style=\"border-color:var(--ast-global-color-2);border-width:1px;border-radius:15px;padding-top:var(--wp--preset--spacing--50);padding-right:var(--wp--preset--spacing--50);padding-bottom:var(--wp--preset--spacing--50);padding-left:var(--wp--preset--spacing--50)\"><strong>About peak beam intensity<\/strong>: The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux.

If it can light up, chances are it\u2019s floating around out there; big, small, round, and now square. Square lights are more mainstream now, and I think it\u2019s a good thing since flat sides lend themselves to compactness and easy carry.<br>Basically, you can make a powerful flashlight, but maintain a small(ish) form factor. The Streamlight Stinger 2020, while more of a hybrid round\/non-round light, was the first I tested, followed by the ice cream sandwich-like Nitecore TM12K. Now there\u2019s another one, the Speras U2T.<br>I overall really enjoyed my time with this one. It\u2019s pretty compact and light for a 5000 Lumen flashlight, handles nicely, and the added versatility afforded by the mounting options and remote switch(es) are a big plus. The wireless switch adds hands-free capabilities which could be very useful for bike use or area lighting. I really liked the rear switch and having instant Turbo as well.<br>I appreciate a simple, easy to use UI, and particularly like the fully regulated output and quick bidirectional charging. Plus it\u2019s a Speras, so it goes without saying you\u2019ll get good quality and reliability. Misses? Not many. The wireless remote antenna sticks out pretty far, so it could get caught on things and get knocked off and lost.<br>The output is good, but it doesn\u2019t last long and I wasn\u2019t impressed with the sustained output. Lastly, despite more manufacturers in the \u2018prosumer\u2019 market switching to non-replaceable batteries, I still don\u2019t like that you can\u2019t swap the U2T\u2019s batteries when they go flat. Otherwise I don\u2019t have much to gripe about. I think I\u2019ll enjoy this one, and if you\u2019re looking for a super-versatile, multirole flashlight, the Speras U2T is worth a look. 4.5 stars for the Speras U2T.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Get 10% off at Speras store with our unique coupon code: <strong>LUMEN<\/strong><\/p>\n\n\n\n<div id=\"buy-3-buttons\" class=\"inherit-container-width wp-block-group review-buy-floating has-border-color has-ast-global-color-2-border-color has-ast-global-color-4-background-color has-background is-layout-constrained wp-container-core-group-is-layout-84466aab wp-block-group-is-layout-constrained wp-container-9 is-position-sticky\" style=\"border-radius:15px;margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--40);padding-top:var(--wp--preset--spacing--30);padding-right:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30);padding-left:var(--wp--preset--spacing--30)\"><div class=\"wp-block-group__inner-container\">\n<h3 class=\"wp-block-heading\" style=\"margin-top:0px;margin-bottom:0px;padding-top:0.2rem;padding-bottom:0.2rem;font-size:1rem\">Discontinued: see alternatives<\/h3>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-container-core-buttons-is-layout-0cc55109 wp-block-buttons-is-layout-flex\" style=\"margin-top:0.25rem;margin-bottom:0.25rem\">\n<div class=\"wp-block-button\" id=\"buy-button-1\"><a class=\"wp-block-button__link has-ast-global-color-7-background-color has-background has-custom-font-size wp-element-button\" href=\"https:\/\/1lumen.com\/best-flashlights\/\" style=\"padding-top:0.6rem;padding-right:var(--wp--preset--spacing--20);padding-bottom:0.6rem;padding-left:var(--wp--preset--spacing--20);font-size:1rem\" target=\"_blank\" rel=\"\"><strong>Best flashlights<\/strong><\/a><\/div>\n\n\n\n<div class=\"wp-block-button\" id=\"buy-button-2\"><a class=\"wp-block-button__link has-ast-global-color-7-background-color has-background has-custom-font-size wp-element-button\" href=\"https:\/\/1lumen.com\/best-rechargeable-flashlight\/\" style=\"padding-top:0.6rem;padding-right:var(--wp--preset--spacing--20);padding-bottom:0.6rem;padding-left:var(--wp--preset--spacing--20);font-size:1rem\" target=\"_blank\" rel=\"\"><strong>Rechargeable flashlights<\/strong><\/a><\/div>\n\n\n<\/div>\n<\/div><\/div>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\" id=\"buy\"><em>1lumen selects and reviews products personally.
