There was some speculation about running the 445 diodes slightly warmer than usual to shift the wavelength more toward 450nm. Has anyone ever proven this theory with a spectrometer or other means? Just curious..

The datasheets temp/wavelenght graphs?
Yes, that would do. Or a mfg P/N for the c@sio diodes?
I had asked this question once before. Took a bit, but I found it and the reply from Planters from this thread: http://www.photonlexicon.com/forums/...-Modules/page2
If you're the smartest person in the room, then you're in the wrong room.
Oh, ok. Interesting. Thanks Absolom!
np! I know this does't really cover any spectrometer analysis, but based on planters' extensive knowledge, I think he is a pretty decent source for info!

Agreed. And thanks for the link to that thread, I read the whole thing. That is some awesome beast he's built there.. wow! =O
My experience with these diodes is that they tend to drop quite a bit of output power the more they heat up. So I don't think there's really any positive benefit to letting them heat up. ...Unless you're trying to warm up small blocks of metal
No, I'm really not looking to toast my dually Took too long to put it together. Just thinking a few degrees up might make it brighter, but alas, no cheap solution to a brighter blue ..
Dually? I think ~2W is plenty of blue!
But you can stack 4 in a quad like |||| without correction and just de-focus the beam to get more blue if you really want.
