I think I'm ready

[Johnnyredd]

Been doing the research, etc. and I think I am ready to try and build a light. It would be two 70 inch bars of 3 watt LEDs over a 125. 22 LEDs per bar, each 3 inches apart. All on dimmers with each "side" on a circuit for timing purposes. 6500 White, 460 Royal Blue, UV and Green would be the colors laid out in this format. My main concern is there are too many whites in it but I am not sure what to add or change. They would be more inline with each other, diagram below is more for planning.

Feedback welcomed!

I would go with 5 watt Cree XT-E Royal Blue binned at 450-455nm and 7.5K Cool White.

You will notice the difference in looks.

Heck bill i just got 3 watt figured out. Now you are changing variables.

With the Cree XT-E Cool White you have 28 different color bins. Depending on which one you choose can make a huge difference in looks as some are more yellow than others.

Also there is a huge difference in the intensity of different 3 watt LED. Cree and Luxion are much more efficient than the Bridgelux knockoffs.

What specific 3 watt LED were you considering?

Cree XP-G.

Cree XP-G.

The XP-G Cool White is slightly more efficient than the XT-E. Say 3-5%.

I prefer the thermal properties of the XT-E and the fact that I can more easily obtain the better colour bins.
