Wow, i checked Ledengin for 15 W Red led, but i don't understand, why blues source cost Thrice as much? (90 bucks each vs 30 for the deep red ones)

I'm thinking my ideal configuration (1 feet x 1 feet of space), would be 2 15 W Ledengin Deep Red, plus 2 or 3 5W blue led from trueopto (nice stats, founds here) and maybe 1 UV or 1 white lamp if i can find a good one...)

Welcome everyone! :hippy:
