Reverse Clicky Tailcap Switch
5 mode: Hi-Med-Lo-Strobe-SOS
XM-L T6 (as claimed)
Tempered Optical Glass
July 19, 2013
- 26650 / 18650
- Good mode memory (after 3 seconds off)
- Good build quality (heavy & thick walled)
- Very nice anodizing and machining (other than threads)
- Nice size in the hand
- Thick glass lens & very hefty aluminum reflector
- Nice beam pattern with wide spill
- Tailstands perfectly
- Springs at both driver & tailcap ends
- Virtually all 26650’s & 18650’s should fit
- Emitters not quite all centered
- Threads were dry upon arrival and squeaky. Rougher than average.
- O-ring missing where the driver/heatsink finned part attaches to the head
- High mode under-driven
- Lack of a medium mode, and low not much lower than high (despite the current draw)
- Tailcap switch feels cheap
Lens: 69.8mm x 2.45mm thick

20mm driver diameter, (pill could be opened up to 32mm with retaining ring opened up too)
Pill available depth 29.7mm
(4) 16mm emitter stars
Appearance of sufficient thermal paste used
At first appearance this light looks and feels really great! It has great machining and anodizing, has some serious heft to it, and just plain feels good in the hand. But that’s pretty much where the good ends and the bad begins.
The threads arrived dry, are gritty, and squeak badly. I’d say the threads are slightly worse than the average budget light. Each 26650 battery I tried (King Kong INR 4,000mAH raised-top unprotected, King Kong ICR 4200mAH flat-top unprotected, and Trustfire Flame protected) rattled a good bit. Even with the KK raised-top, a severe shaking of the light will cause it to change modes.
Upon disassembly you see that the “heatsinking fins” are really just for looks as the area where the LED’s are mounted in the head do not make direct contact to them. Heat must be transferred from the head through threads to get to these fins. After leaving the light on for about 5 minutes I noticed a lot of heat at the glass lens and the bezel, but almost none at the heatsink fins.
Generally speaking the output on high is quite nice with a very nice wide floody beam pattern. I was impressed with the beam. It still has a very distinct bright hotspot, but yet a bright wide flood. Going through the modes I quickly thought “what the ???” until I realized there is no medium mode but rather a second occurrence of high and then a low that is almost indistinguishable from high. Of course there is the typical strobe and SOS mode following, with the strobe being what I would call medium speed. One surprising feature is that the driver has good working memory which remembers your last mode so long as you leave the light off for three seconds or longer.
I measured tailcap currents with the three different 26650’s mentioned above and noticed that the current increased as I pressed in harder against the driver spring. Seems this light could benefit from a resistance mod at that spring (and even a longer stiffer spring). All three batteries were fully charged a few weeks prior, but were down to a voltage of 4.13v at the time of testing. Results were as follows:
High - 4.06A
Low – 1.12A
High – 4.27A
Low – 1.10A
High – 3.65A
Low – 1.11A
The LED’s are wired in parallel and the driver is neither a buck or boost driver so the approximate current to each LED with a tailcap current of 4.27A would be 1.07A though that assumes 100% efficiency. A well driven SkyRay King will easily beat this light for output.

Emitters (wiring seems to be of good sufficient gauge - 20AWG?):
Thick glass lens and thick o-ring:

Cavernous driver cavity (notice how the head is not directly connected to the heatsinking fins):

Photo showing the full width of flood from this light (light in the center sitting on the deck rail):
During my beamshot photo shoot I noticed that I can easily light up objects at over 400 feet away. At 750 feet it lights them up very dimly. The light really does have some throw to it too! As you can see above, the amount of flood this light puts out is awesome!
This light is just way overpriced for what it is. Even if you had extra money to burn on a mod host it just doesn’t have the heatsinking to handle much more than the heat it generates now. It’s such as shame since this light looks and feels so nice (for the most part).
