I'm currently running a 36" Ray2 DS on my 12 long and for the most part, I'm very happy with the light and seeing as how I already own it, I'd like to keep using it.
The problem I'm having is that the Ray2 doesn't keep red plants red because its red spectrum output is almost nonexistent. You can check out the spectrum chart here
So, I've been thinking of remedies for this and the best I can think of is building a supplemental red spectrum strip.
I have minimal experience with DIY LEDs and was hoping some of you might have some thoughts on the subject.
The tanks dimensions are 35.4 x 8.3 x 9.4 inches. I currently have the Ray 2 3.5" above the tank with the deepest part of the substrate roughly 10" below the light.
I was thinking of picking up a 36 x 1.4 inch heatsink and 6 or so Philips Rebel ES 660nm Deep Reds from Rapidled.com. I'm not exactly sure about the driver etc, I still have my research to do.
I realize the excess of red spectrum might throw off the aesthetics of the tank, but I figured I'd cross that bridge when I came to it. I could always swap out some LEDs to find a balance between what I like and what my plants like,
So, thoughts, suggestions, criticism, is this a utterly ridiculous idea? I have no idea. What I do know is I'd like my reds to actually stay red and I'd like my lighting, whether it's a piecemeal setup or a single fixture to have a spike in both the blue and the red spectrum.
Thanks in advance. And seriously, if this is a dumb idea, please tell me that and tell me why, as I said I'm new to this whole DIY LED thing.
