I really like mine too. Very nice, and I've had it quite a number of months now, works like a champ.
Sure, take that little head off it and put something a little more substantial on it. I'm thinking one of these, at a minimum: [img]
One really big gaping hole I see here is the relative safety. Lithium cells have a history of failure when there are multiple cells in the light,...
Thanks! And it performs much better than it looks, most especially with the new kick-:censored: SiRF chipset!
Using the term, uC controlled current regulated driver would imply that all the levels are current dimmed. Is this correct? The CREE XR-E is...
Vertical units, for light output 100 = 100% of the light that the light produced. So, if the meter read 600lux in the beginning, that would equal...
How many fully automated hands off CNC machines are in your shop, Rothrandir? Go look up some of the ones done by McGizmo (probably the most...
Of all the people here, I wouldn't expect you to understand Roth. Lights out automated CNC isn't that bad, it takes no manpower, once you start...
Amazingly, this low cost light is still going strong for me, with no issues yet- after six months of use. Sure holds up nicely.

I currently live in the PNW forrests and spend a great many hours in the forrest each year. I enjoyed Orienteering when I was young, and during...
Depending on your photon managment, such as if you want a throw light, you can do some great things with very little power, such as these here,...
The meaning of the word tactical, which would apply to flashlights: "of or pertaining to a maneuver or plan of action designed as an expedient...
Titanium is a very poor thermal conductor. Titanium has 10x higher thermal resistance than Aluminum, and nearly 20x higher than Copper. High...
I sure hope they didn't use PWM for dimming, it drives me nuts.
Once sapphire is AR coated with the right stuff (and it is extremely cheap to do, as sapphire only needs one layer instead of 23), it nearly...
Okay, so what makes this sucker tick, and how does it actually perform? First, the drive waveform on the pins of the LED, from the switcher that...
