Ok guys, working on my projector build & currently sorting the red.
Which do you think would be better? Beam visibility is important more than graphics.
Straight 2.8W of 660 ( prob 2.4W after optics )
Straight 1.6W of 637 ( approx 1.4W )
Mix 2.2W of 660 & 637?
Some other mix....???? include 642???? I have 8 diodes to play with.
Cost is a factor so is it worth starting with 660 & upgrading as funds & experience allow or is it pointless? Would it be a good idea to get all working / built on 660 then upgrade?
Thanks
