Hello!
I have been looking into building new terrarium and I have been doing some research on lightning. I would want to go with LED lights and yestarday I stumbled on these at digikey:
http://www.digikey.com/products/en?FV=ffecd831
They look really tempting to me (easy to connect and pretty high effiency). I was thinking about buying fishtank about 120cm x 40cm x 40cm and I thought maybe two of those 1120mm long led "fixtures" would be enought (both roughly 4900 lm).
There is 5700K, 4000K and 3000K, I guess I should go with two 5700K or with one 5700 and one 4000K to get some red wavelengh as well? The spectrums can be found from the datasheet here:

I have done some research and I used the calculator (http://dev.edman007.com/~edman007/pub/par-dli-cal.html) mentioned in this thread:
http://www.flytrapcare.com/phpBB3/how-m ... 31035.html , to get some idea about how much DLI would I get with 5700K. The problem is that it seems it doesnt really calculate much of the blue vawelengths for the DLI, with 2x4900 lm I get DLI of roughly 10... Has anyone else used that calculator?
Thanks in advance for any help!
