Are these LEDs any good?

[adriandj]

I am planning to get these type of cheap of LED bulbs to supplement my current lighting in my tank. Mainly to light up the dark spots. Are these good to grow corals? Anyone using or has used these? Thanks!

I'm skeptical to say the least. The spectrum is??? the par value is???

If it was that cheap and easy every one would be using them.
