PROS
A lot of power! Handy package Steady clip Comes lubed
CONS
Can be very hot to the touch! Only in black No thermal compound under the led
Compared to a previously bought clone, https://www.fasttech.com/p/1174500, this unit is brighter and has less runtime, with more than 3A measured tailcap current on high with a freshly charged battery. The led is held in place with a tight fit plastic ring over a solid pill; the other clone uses a threaded metal ring, and the pill has a small hole. Both flashlights reach very high led temperatures; using an IR thermometer closely focused over the leds with no lens, I get higher than 110 celsius degrees of temperature deltas, having seen close to 150º of led temperature... Wow! Guess the led won't last very long under such circumstances, buy hey, you can always buy a replacement.

PROS
Cheap enough Fair capacity
CONS
None
Powering up a clock these are already lasting more than other el-cheapo cells. My old "game & watch" units seem to be happy with them also. Great product at a fair price.

PROS
Ultra low dropout linear driver Adjustable current output for all 3 regular modes
CONS
Onboard MOSFET could get a bit hot depending on output current and available cooling
Fully regulated linear driver with extremely low dropout, probably below 50mV in most cases. PWM free. Current adjustable for all regular modes (except strobe). With pleasantly hidden (double click) 12Hz 50% duty cycle strobe mode.

PROS
Inexpensive Nice cone of consistently distributed light
CONS
Inconsistent light transmittance between samples
Out of my 5-pack I found large variation in light output between lenses, up to 15% between worst to best and all else being equal. So better grab a much bigger pack than needed so you can ditch the low performers, if you care about this, of course.

PROS
Nice looking anodization finish Great quality overall
CONS
No led centering ring, just a poorly cut plastic disc to isolate the emitter board from the reflector
Made a build with this host, a 7x AMC7135 Nanjg driver and a Nichia 219C 4000K Ra9050. Floody beam with wide hotspot, quite pleasing. Recommended!
