just remember some times cheap ant always better bud.

 

Yea, but if i can make it work and replace every year even its $30 to replace.

 

Try it and let us know how it goes. I won't be pessimist, but I have never seen any wonderful LED lighting come from eBay. Threads on RC are littered with people unhappy with their "eBay bulbs" be it LED, MH, or t5.
My immediate concern would be that LEDs are a point source light. The way those look, you are just going to get two ultra strong beams of light in your tank, perhaps frying everything directly under it, but not providing enough light for everything else.

 

No blue lights.

 

I can get blue ones.
