disaster999 Posted September 14, 2012 Share Posted September 14, 2012 what do i need if i have 18 cool whites, 18 royal blue and 18 regular blue? do i still need OCW or i can skip that and add 495nm and 660nm LED? how many would i need? Link to comment

I would say you need only about 5-6 of the OCW so in this case you can get rid of 12 of the Blue and add 6 495nm and 6 660nm. Link to comment
disaster999 Posted September 15, 2012 Share Posted September 15, 2012 i based my design off the AL SOL so i had equal amount of white RB and blue i run half my blue at 1amp and the other half at around 700-800ma i might ditch some of the blue and replace it with some RB and add 495nm and 660nm Link to comment
