Guys (and gals?), no worries, I
think I've got everyone covered... and also think we may have exhausted the supply of Milky Candles with Nichia GS!
oo:
Zero MC2 with Nichia GS remaining as of this post.
That said, I've got a few other styles of 5mm LED and enough parts on hand to build several more Milky Candles... so if anyone missed these, there's still hope. I intend to post a new sales thread about the possibilities... for now, here are some ideas that stand out, if interested feel free to send me PM and/or email about them...
1. I still have some Jeled 50Kmcd white LEDs on hand, and though they're not quite at Nichia GS levels of output, they still perform surprisingly well. Fellow CPFer Nein166 and I ceiling-bounce tested several LEDs in the MC2 units and the Nichia GS won, followed fairly closely by the Jeled 50K, followed somewhat more distantly by the rest of the field. The Jeled is still a great performer! I can build using these immediately.
2. Have some 10mm white LEDs that do nicely. What these lack in output (and they don't lack all that much, they're perfectly acceptable in the MC2) they make up in surprisingly long throw... the optical system in the larger 10mm emitters, at least in this case, is a HUGE improvement over their 5mm cousins! Who would ever have imagined describing a Milky Candle as a thrower!?!
oo:
3. I've built some prototype Candles in the past using Cree LEDs... I would typically use something that's a little outdated for the higher-powered lights, but still quite competitive in lower-powered applications like the MC2. At present I have cooler-tinted P3 (WC tint) and warmer-tinted P4 (WH tint). These produce a wider-angle, floody beam. The build would be slightly more expensive using these, but not by much.
4. I have some 'snow' white LEDs of unknown origin that came from ebay a while back... the beam is exceptionally smooth and tint is what I would call a frosty white. They're not as efficient as the Nichia GS or the Jeled 50K, but I could probably overcome that limitation by mounting a small array of these, perhaps 2-4 in parallel... that would allow them to operate at a more favorable point on their efficiency curve and narrow the gap with the top performers to the point they'd essentially be equal to them. Price would be a bit more by going this option... maybe $10 more? due to the additional labor involved... but the beam would be smoother and more uniform than any of the other choices while still providing the good ceiling-bounce illumination the Milky Candle is designed for.
I'm sure there are other possibilities as well! Let me know if any of these interest you. It's kinda like a Milky Candle Emporium!
