    I'm back, and I'm building another Quad P60.

    Hello! It's been a long time, I know. I apologize for leaving abruptly a few years ago, life threw me a couple serious curve balls at once. I'm back on track now though, and I've been working on a new design for quite some time as I've been able to. If anyone has any grievances regarding my...

    The "FETtie" - 500W Tailcap Switch for Z41 / FM26XXX

    Introducing the ultimate high power tailcap switch for Z41 and FM26XXX hosts. Designed as a suppliment to the 1450 Lumen P60 Quad drop-in. This switch's capabilities extend well beyond it's originally intended necessity. The P60 Quad thread is quite longwinded now, so I wanted to make a...

    Sold/Expired FETtie 12A tail switch for solarforce, tester needed.

    This is not the full sales thread. Looking for someone with a solarforce L2P that wants to test my switch for fitment in their light. I'm nearly certain that the tailcap and light is exactly the same dimensionally as the uniquefire clone I was using to test, but I want to make sure before I...

    Sold/Expired P60 Quad XPG Drop-in, Silver plater copper heatsink.

    Some may have seen my thread here: http://www.candlepowerforums.com/vb/showthread.php?t=267366 This drop-in was the first prototype for the silver plated copper version. The LEDs are soldered directly do the 99.9% pure copper heatsink, and then plated in 99.9% pure silver. These copper...

    Can't order from KD?

    I've searched around to see if anybody else is having the same problem, but doesn't seem so. I can't login (I don't know why they decided to try and make you do that) Whenever I try, it says password doesn't match login, but I'm getting the email to recover my password and using it.. still...

    1765 Lumen P60 Quad XPG Silver Plated Copper Heatsink Direct Drop-in, in developement

    So I had the idea to do this a while ago, I wanted to try and cram as much light as I could into the P60 format, with heat buildup being the limiting factor I knew multiple CREE XPGs would be the best choice to keep efficiency up. I used a 1" diameter 4 LED optic and modified it to accept a 5th...

    High Resolution Clamp Meter for Current Measurement

    Until a few years ago clamp-on meter resolution only allowed you to measure to the nearest 100mA, which is no good for power LEDs and such, but recently meters have advanced as far as allowing a 0.1mA resolution, negating the need to measure the voltage across current sensing resistors to check...

    Lowest ESR ceramic caps for LED drivers?

    Trying to maximize efficiency for an LED driver I'm building, and I'm looking for the lowest possible ESR (equivalent series resistance) ceramic capacitors. In the past I have used the panasonic ECJ series capacitors, which are "low ESR" caps, but they do not actually give a value. I have been...

    RGB array, why blue so hot?

    Using some luxeon rebels in an array, 3 red, 3 green, 3 blue. All SMT soldered onto triple mounting MCPCBs and screwed onto a large heatsink. Running 700mA through each colour in series. I've always thought that the green with only about a 5% efficiency or so, would get the hottest. And the...

    IP65 LED array enclosures for outside?

    I've been searching for a while now and haven't been able to come across any IP65 rated aluminum enclosures for LEDs. If anybody knows of any specifically for LEDs that'd be awesome. If not even just a slim profile IP65 aluminum case with a window on the front that I could attach heatsink(s)...

    Sold/Expired Ultimate MC-E copper mounting solution

    Doing a run of these, quantity limited right now to 20, but more probably available later. Cost is $14 each. Shipping is $5 within North America, $10 for overseas, but in most cases I can probably refund some of that. If you'd like me to surface mount solder the MC-E for you it's another $2...

    The Ultimate MC-E Mounting Solution?

    I'm very excited for the new MC-E coming out. I've already designed and built a driver for the MC-E, and I'm almost finishing turning a host for it on the lathe. Since the 4 die construction will be much more thermally dense than 4 separate LED packages, I want to be able to eek out every...
