I don't know where Dr Laser is quoting his numbers from, but he's posted several times in the last couple weeks suggesting that you need more green than blue.
Actually I didn't pay attention to green I was calculating based on red as a most weak for a human eye. He has 440nm@660 which is as I said about ~130mw@635. (Actually formula for 660 is 4-1-1.5 So to be more exact 110mw)The formula I use for 635 is 2-1-1.5 2 red 1 green and 1 and half blue.
So 110/2=55+27=80mw Plus green if it's placed at the back of the mixture chain will loose some of it's power because of optics. 440@660 is just not enough for 250mw blue and at the end it'll make a very very blueish white.
Actually it'll be cyan.
If 440 was @ 635 then yeah 440mw red 200 green 250 blue. But his is 660nm.
I hired an Italian guy to do my wires. Now they look like spaghetti!
