I* have been wondering about the number of flashlights that use the 26.5mm drop-in with either LED or incan.
Why is nobody making heatsinks and/or finished modules for them?
(Moh, I am looking at you. :))
The only problem I can see is that tolerances of hosts may wary a bit and necessitate a...
How does one decide the correct current for a pump diode?
I have several pens, two app. 50mW, and now one +120mW green.
The 50mW use app. 0.5A the +120mW about 0.75A.
I am planning* on making a P/I curve for the 50mW ones and trying to find some optimal point.
Does anyone have a guideline for...
I have just finished my new quick and dirty fan cooled handheld. :D
The host is from Mohrenberg, a nice spacious one where the side clicky have lots of space underneath. The diode is from Morgan, fan from boscoj, and the driver is a simple linear one from Aixiz set to 400mA.
I had to remove...
My browser have recently started using something like 100% of the processor when viewing LPF.
It mean an incredible lag.
Have there been any changes to the ads within the last 12-24 hours?
I am running Firefox on an Ubuntu laptop. ETA: Setting NoScript to ban the Laserglow banner solved the...

Later on I cancelled my order due to delays.

I came home from my ship last night, to a full mailbox.
Among the stuff were an envelope from Hong Kong, it contained a pair of red glasses and a "5W" flashlight.
I have not ordered those two items together and have no idea who sent them?
Any idea what I can do, is it likely that somebody else...
I have just dismantled* my Fenix PD30, the pill? appear to be solid with holes drilled for wires, so fitting a driver in will not be easy.
I am thinking of making a cylinder 14,2mm long and 18,8mm wide with a hole for a 9mm module, or front and business of a 12mm module. It would replace the...
I am not quite sure where to put this.
Does anyone know of optics that will let a small flash light give a laser like beam at night?
It would have limited practical purpose, but I think it would look cool to have a LED 1xAAA or such that can make a dot at several hundred meters.
