Lumintop has a pretty deep line-up, especially when they notice that a particular product is catching on. They picked up production of the now-famous FW3A and it sold like hotcakes. So what do we have now? About 100 (ok, maybe not but close) iterations of the FW3A in different sizes, materials, emitter choices, and battery configurations. The BLF GT is no different. If it works, make several variations and see what sticks, right? Ok, so Lumintop has us flashlight enthusiasts figured out. Yes, some of us will buy every version of a product. So when the Lumintop GT3 and the GT3 Pro have been out for a while, you know what that means – yes, it’s time for a new version! This time, Lumintop went with a “Mini”. It’s instantly recognizable as being in the GT3 family, but this pint-size version sports a single 26350 battery (yes, you read that right) and “only” 6500 lumens.

Package quality.

The Lumintop GT3 Mini that I received was a pre-production light and arrived before any of the packaging, manuals, and other things were ready. Because of that, it showed up in a plastic bag with nothing else except for the battery. So in all that means we’ve got:

• Lumintop GT3 Mini
• Unbranded (“BFH”) 26350 battery

What do you call a “baby” (mini) soda-can style light? It’s no longer a soda can… is more of a shot-glass light, I suppose. It looks pretty cute, but its output is anything but. Remember, it’s packing about 6500 lumens. The design language definitely mimics its bigger brothers, in a package and nestles into my fist. The tailcap is perfectly flat, so tailstanding is no problem. There’s a single e-switch on the side of the head which lines up very nicely with the branding that is etched into the anodizing. The button has that adorable bunny that we know and love, and the button is illuminated with a blue LED that can be turned off, if desired. There is no pocket clip, but there is a captive ring by the tailcap that spins around and has a place to mount a wrist strap. The round body does roll around on a table top, so be careful laying the GT3 Mini on its side.

If I’m being honest, this isn’t the most practical light. Lots of lumens and tiny bodies don’t pair well together unless you’re ok with severe throttling issues, as you’ll see on this light. So why would you want the Lumintop GT3 Mini? Well, if you’ve got a Lumintop GT collection, you’ll have to buy this if you want the complete collection. Or maybe you want a light that’ll fit into your palm and can still light up a ball field, if for a few moments. Perhaps you could use this around the backyard or to walk your dog, so long as you’re ok with a 500-ish lumen light that can momentarily give you a big turbo boost up to 6500 lumens. If you’re looking for sustained high output, this is not your light.

The Lumintop GT3 Mini is machined out of aluminum and then hard-anodized. The manual (found online) doesn’t really have specs about the exact anodizing process, but it seems to be well executed – very clean, smooth, and even. It’s on the matte side of things.

The body tube and tailcap don’t have knurling, per se. There is a pattern cut into them that is a miniature version of the big and beefy pattern that I saw on the GT3 Pro. The machining is really well done. The GT3 Mini seems purposefully chunky and yet refined.

Lumintop’s warranty policy is as follows (as copied from their website):

• 30 days free replacement: Lumintop will replace or repair products with manufacturing defects within 30 days of purchase.
• 5 years free repair: Lumintop will repair the products free of charge within 5 years (accessories 1 year, products with built-in battery 2 years)of purchase if problems develop with normal use.
• Lifetime warranty: If repair is required after the guaranty period, we’ll charge for parts accordingly.
• This warranty does not cover normal wear or tear, abuse, force majeure damage, or defaults by human factors.

While Lumintop opted for some Chineses SFH55 LEDs on the GT3 Pro, the GT3 Mini marks a return to Cree LEDs. There are 3x Cree XHP50.2 LEDs, to be precise. The LEDs are centered in a clover-shaped orange-peel reflector. That is protected by a piece of glass and held in place by a stainless bezel ring, which is always an appreciated touch. Stainless steel and black anodizing look great together, and the extra drop protection from the steel is welcome.

Additional info on the UI: 

• Aside from the hold-for-off, this UI reminds me of a dumbed-down Anduril

The Lumintop GT3 Mini uses a single 26350 battery.  That’s an unusual size, but they can be found. Unfortunately, I didn’t have a 26350 available. Lumintop was kind enough to send one along. Assuming Lumintop offers one to go with the light, it’s probably best to just pick one up at the same time.
According to the manual and Lumitop’s website, an extension tube will also be available separately that will allow you to use 26650 batteries with the GT3 Mini. If you want higher output or much longer runtimes, that’s a good option to have. Just know that the extension tube isn’t supposed to allow you to run the light in Turbo/High for longer bursts. Lumintop says the GT3 will actually step down faster using the larger battery. Lumintop did not send the extension tube with for testing, so I can show you any of those results.

Lux was measured by a UNI-T UT383 BT at 10 meters. Lumens were measured in a homemade lumen tube using a TSL2591 sensor, calibrated with a Maukka calibration light. The temperature was monitored with a MLX90614 IR temperature sensor. The included 26350 battery was used for testing.

Lumen measurements (for each mode)

Mode	Amps at start	Specs	Lumens @turn on	Lumens @30 sec	Lumens @10 minutes
Moon	7 mA	2 lm	1.6	1.6	–
Low	0.2 A	130 lm	100	100	–
Med	1.0 A	550 lm	432	432	–
High 1 (26350)	3.3 A	1800 > 550 lm	1188	1187	432
High 2 (26350)	7.7 A	4000 > 550 lm	2830	2777	433
Turbo (26350)	14.7 A	6500 > 550 lm	7372	432	431
Turbo at 3.6V			6064	433

Parasitic drain:

• 142 µA with button aux LED illuminated 
• 16 µA without button aux LED illuminated 

On Turbo, the GT3 Mini hit the max output spec, as long as we’re not talking about ANSI FL1 ratings. Within 17 seconds of Turbo being activated, the output dropped off a cliff and was down to 432 lumens before we made it to the 30 second mark. Even High 1 and High 2 (which both missed their output claims) were down to ~432 lumen before 45 seconds. So unless we’re talking about brief hits of High/Turbo, we’re essentially looking at a 432 lumen light. Which, if I’m being honest, I find disappointing.

Battery Life: Runtime graphs

Using a 26350 battery

Mode	Specified runtime	Measured runtime ANSI	Time till shut off
Moon	8 days	–	–
Low	7 hr	–	–
Med	2 hr	–	–
High 1	1 min + 1 hr 40 min	1 hr 53 min	1 hr 54 min
High 2	40 sec + 1 hr 40 min	1 hr 40 min	1 hr 46 min
Turbo	20 sec + 1 hr 40 min	1 hr 49 min	1 hr 50 min

Runtimes were very close to spec.

ANSI FL1 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.

Peak beam intensity and beam distance measurements

Mode	Specs	Candela measured	Meters	Yards
Turbo (26350)	20,500 cd	20,000 cd @ 0 sec1,600 cd @ 30 sec	283 @ 0 sec80 @ 30 sec	309 @ 0 sec87 @ 30 sec

Intensity was also very close to spec… as long as we’re talking about turn-on values and not the ANSI FL1 readings at 30 seconds.

Extra info: Peak beam distance according to ANSI FL1 standards: 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). Columns Meters and Yards show rounded numbers.

Camera settings and distance: 

• Beam shots of the building are taken at 15 m (16 yd) using a Pixel 7 set to ISO 200 with 1/10 second exposure time.
• Beam shots of the playset are taken at 30 m (33 yd) using a Pixel 7 set to ISO 200 with 1/2 second exposure time. The trees in the background are around 65 m away.
