Short write-up. Review of 1-mode here https://budgetlightforum.com/t/-/2557 (but this copy is 3-mode H/L/Strobe....strobe is critical to me as i'd like to have a blinky signal to attract attention, just for standby as anything can happen be it emergency or non-emergency).
Build quality - 8.5 out of 10. This has pretty thin walls but is an advantage as i want it light for "a big powerful EDC".
High is very bright. I'd suspect 2A and above.
Gets hot pretty quick. I can't imagine > 2 mins use. It gets hot slightly faster than a DRY CW direct drive. But for 1 min use it is definitely possible and applicable.
Pretty decent throw - hotspot is not too big, not too small.
Low is pretty low. Measurements will come tonight (lux meter and amps)
Best thing is - PWM is literally non-existent! The current crown goes to the Ultrafire U80 which has 500Hz PWM in the low modes. This one has about 2kHz, i will verify later. Even if you very vigorously wave it around, you can barely, and i mean barely see the dots. ie PWM is as good as the branded lights. This is unheard of previously for super budget lights esp for the "bottom trawlers" for this.
This light is cheap during the group buy and you get registered shipping even for that price! It was like $12 + $2 registered air mail. What the....
Measurements :
2.9A at the tail with freshly charged NCR18650 2900s. I think it might be DDed, relying on the resistance of the components so not too bad.
81.4 lux throw at 8.17m = 5.4k cd. That's 73m of throw (ANSI FL)
Reflected light measurement is on par with stuff like Ultrafire U80, slightly worse than say the monster Fandyfire STL-V6.
As for drop in output due to heat, it drops from 63 lux in reflected ceiling bounce -> 54 lux from T=3seconds to T=60 seconds. 15% drop. This means it is slightly better than a foil wrapped Ultrafire P60 XM-L in my L2T.
So far, my 3 deliveries with Dinodirect is ok. Here's the link : http://www.dinodirect.com/led-flashlight-1000lm-3mode-cree-t6-super-bright.html
