The Speras B7 is a compact’ish, triple LED headlamp. Having both flood, spot and red lamp modes.

One of the most interesting aspects of the B7 is the battery, it comes with 3xAAA which is not so uncommon. But what is unique is the Li-ion LC12 102936 battery. It is removable and fits in the 3xAAA battery tray. Giving a great alternative to NiMh or regular AAA’s.

What's in the package

The B7 comes in retail style packaging with all the stats and info on the box. The headlamp comes with:

• 3x alkaline AAA’s
• Li-ion LC12102936 battery
• USB-C charging cable
• Headband
• Instructions

The B7 is an all plastic affair, with a somewhat rubberised main section, a bit like you may find on a camera. I like it, it still feels a quality product and being plastic is lightweight and feels durable.

The headband is nice too, it is fairly broad, with the right amount of stretch and nice looking Speras branding.

I have used the B7 extensively while testing, as headlamps can be very handy tools. For close up use it has been mostly good. Although I do wish it would tilt further forward, to allow you to better read a book or some instructions or when working on things close up. On the other end of the scale, the spot beam is far too floody to be called a spot beam, giving quite limited range if you wanted to use it out in the open or walking across the fields.

It is a comfortable headlamp to wear and easy to adjust. The B7 is fairly compact, but it is bigger than some other similar headlamps on the market. This is likely due to being AAA compatible. As you need to make room for such batteries. This does make the B7 slightly more nose heavy and the depth of the unit again compounds the available downward angle of the light.

Speras do not give much info away to the LEDs in use. There are 3 lenses, the largest uses a domed LED, with a clear plastic lens and a frosted/heavy orange peel reflector. This is actually the “spot” LED. Although in practice it is still very floody.

Next to the main LED is a small slotted TIR optic, this is the ‘flood’ LED. And slightly off to the side and below is the red LED behind an even smaller TIR optic.

The main 2 LEDs aren’t too bad in terms of tint and colour. Not the best, but in real world actual use I didn’t really have any issues. My only real complaint is both beams are very floody. In fact if you could get rid of the flood beam you’d still be happy with the amount of flood you have. The ‘flood’ LED is also substantially lower output. Which seems a little odd, meaning that you end up using the spot beam even for close up tasks.

My main gripe here however, is the red LED. It is probably the ringyest beam I’ve ever seen on an LED light in the past 15+ years. It is that bad.

Flashlight size comparison with its competition:

Group 1: Speras B7, Nitecore NU25

Group 2: Speras B7, Convoy T3

Available modes: 

• High Spot & Flood
• High - Spot
• Medium - Spot
• High - Flood

• Red

Available blinky modes:

• SOS (red LED only)

The B7 has two switches, one for the red LED and one for the white LEDs.

From OFF (right hand switch):

• Single click: On - Medium Spot

From ON:

• 1 click if done in less than a couple of seconds: Scrolls outputs: Medium - Spot | High - Spot | High Spot + Flood | High - Flood | Low - Flood | Off
• 1 click if done after 3 seconds: Off  

Mode memory:

•  No

Shortcuts:

• To Low: No
• To Turbo: No
• To Strobe: No

From OFF (right hand switch):

• Single click: On - Red

From ON:

• 1 click if done in less than a couple of seconds: Scrolls outputs: Red On | Red Strobe | Red SOS | Off
• 1 click if done after 3 seconds: Off  

Strobe/blinkies

•  Only with Red LED

Lock-out mode: 

•  No

PWM

• No that I could detect

Additional/summary info on the UI: 

• The UI is ok, it doesn’t mean scrolling through multiple outputs if you want say, “Flood - low”. So I tended to only use the Spot Medium and High modes. They seemed to work well enough for most purposes. The fact it then turns off when you next interact with the switches is handy, although it does mean if you want to change outputs you’ll have to start over from the beginning.

The B7 has no battery indicator. Although there is a charge status light on the LC12 battery. Green for charged and Red for charging.

Battery level indicator:

• None

Lumen measurements

How Lumens are Measured: Understanding ANSI FL1 Standards

About Lumen measurements: The ANSI FL1 standards specify that output in lumens should be measured 30 seconds after turning on, as this is the standardized time for measuring brightness according to the industry standard. This is why we focus on this part in our measurements. The ANSI FL1 standards require an ambient temperature of 22 ± 3°C. We record the ambient the ambient temperature to identify potential reasons for any observed discrepancies.

To test the performance I use a homemade integrated sphere for lumen testing using a dedicated light metre. I also use the CeillingBounce Android app for measuring throw (at 3m) and runtimes. Both are calibrated using a 1Lumen supplied calibration light.

Tested with the included battery/

Mode	Specified output	Turn on	30 sec.	10 min.
Medium Spot	90 lm	59 lm	51 lm	-
High Spot	240 lm	138 lm	138 lm	113 lm
High Spot + Flood	600 lm	307 lm	307 lm	122 lm
High Flood	115 lm	38 lm	33 lm	32 lm
Low Flood	10 lm	2.6 lm	2.6 lm	-
High Red	3 lm	1.4 lm	1.4 lm	-

Ambient temperature during testing:

•  16°C 

Parasitic drain:

• Yes, minimal, but unable to measure.

Battery Life: Runtime graphs

How Runtimes are Measured: Understanding ANSI FL1 Standards

About ANSI FL1 runtime standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

Mode	Specified runtime	Runtime (ANSI FL1)	Time till shut off*
Medium Spot	10h 00min	Not tested	Not tested
High Spot	5h 00min	4h 17min	4h 17min
High Spot + Flood	3h 30min	3h 23min	3h 23min
High Flood	5h 00min	4h 52min	4h 52min
Low Flood	51h 00min	Not tested	Not tested
High Red	60h 00min	Not tested	Not tested

*The last column reflects the total runtime until the light turns off. A "+" symbol indicates that the test was stopped at that point, but the light continued to run. This typically occurs with certain drivers, firmware, or battery types.

Peak beam intensity and beam distance measurements

About Peak beam intensity: Understanding ANSI FL1 Standard

About peak beam intensity: The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object). This means that the intensity has decreased so much, it becomes difficult to see darker objects, or objects that don't reflect light. The columns ‘Meters’ and ‘Yards’ use rounded numbers.

To test the performance I use a homemade integrated sphere for lumen testing using a dedicated light metre. I also use the CeillingBounce Android app for measuring throw (at 3m) and runtimes. Both are calibrated using a 1Lumen supplied calibration light.

Mode	Specified intensity	Specified beam distance	Candela measured	Meters	Yards
Medium Spot	-	40 m	336 cd	37 m	41yd
High Spot	-	70 m	920 cd	61 m	68yd
High Spot + Flood	-	92 m	1910 cd	87 m	95yd
High Flood	-	20 m	115 cd	21 m	23yd
Low Flood	-	7 m	16 cd	8 m	9yd

Canon EOS 200D, Canon 18-55mm EFS IS used at 18mm, ¼ sec, F4.5, ISO 1600, WB 5200k

Beamshots of the following flashlights compared:

• Speras B7
• Convoy T3
• Mini Maglite AAA

Flood light beamshot is not available because it's too weak.

Please note that the following beamshots are mainly intended to showcase the beam pattern and beam quality, rather than overall performance. These images are typically taken directly after activation, and in different seasons or weather conditions, and therefore do not fully represent its overall performance. In few cases the camera settings are even different and therefore not meant for performance comparisons. For accurate performance metrics, such as output, beam distance, and runtimes, you need to look at the performance section of this review.
