Help with RGV balance

[IsaacT]

I am looking to make a very simple RGV system pretty soon. I have a PHR in an old labstyle build I did, and it never gets any use, so I figured I could fix that lol.

So assuming I use a PHR at 125mA, what would be the appropriate other powers for the red and green? Red will be 650nm, and green 532nm.

Thanks,
Isaac

I did some searching but I just don't know how to look for this.

Check out Chroma over on PL, it's a great color mixing tool. Not entirely accurate at times, but it gives you a best approximation.

You'd probably need ~75mW 660nm and ~50mW 532nm to balance out 110mW 405nm.

Using 650/532/405 where 405nm@150mW, I get:

650nm @ 75mW
532nm @ 30mW
405nm @ 150mW

I remember I couldn't download Chroma in the past because i had a Mac, but I have a PC instead now so I'll go try it!

EDIT: I cannot get the download link to open over there...keeps giving me an error "server not found"

Using 650/532/405 where 405nm@150mW, I get:

650nm @ 75mW
532nm @ 30mW
405nm @ 150mW

At 125mA to the 405nm he's only going to get ~110mW (maybe less)
405nm = 110mW
660nm = 90mw (or 650nm = 60mW)
532nm = 25mW

225mW white light

I've always heard the ratio should be about 4:1:4 for those colors.

Common mistake: common "DVD" diodes are not 650nm at all. They're at least 660nm and sometimes as high as 665nm if you drive them hard.
