Where can I get really white 5mm leds? For minimag direct drive...

[KDOG3]

I trimmed the leds of an SMJLED from the shoppe yesterday and just plopped it in a minimag for a low power long runtime light. The output is actually pretty decent, but it's terribly blue. I'm wondering if there are any REALLY white 5mm leds I can get a hold of. Particularly cutdown that will work with a reflector nice.

try the older MJLED.
Less blue but also less light.

I bought their high power ultra white LED and was happy with them. I use them in my E0's. http://theledguy.chainreactionweb.com/product_info.php?cPath=48_52_24&products_id=578

As for China LED's, I find them hit or miss. I've put them into night lights thinking I was upgrading from the stock LED's, and even though they were initially bright, they got dim in a few weeks, unusable in a few months. Took them out, the LEDs were brown.

What about these TH3Cs' and "SnowLEDs" I've heard about?

What about these TH3Cs' and "SnowLEDs" I've heard about?

I use the THC3's direct drive in Mini Mags. They're great with lithiums, OK with fresh alkalines, and not very bright with NiMH's. Still, I use them with all three types of batteries. I'd say with lithium's, the THC3's are quite a bit brighter (overall) than a stock Mini Mag incan, about the same with alkalines (after the initial sag) and dimmer with NiMH's. But, for specific purposes, all three chemistries work well, and the runtimes are out of sight! I estimate 50 hours with lithium's and who knows with alk's and Nimh's.

I think the Peak snows are whiter, but the THC3's aren't bad, with just a hint of blue. Way better than Nichia's. I don't know where you can get the "snow's" anymore though.
