Suspended LED fell INTO tank

[estubbaly]

I am using this, $82 shipped right now

What I found this LED stand out from the other eBay LED are:
1.It has lens that has non visible disco ball effect, at least what I can see.
2.Each LED chips has a zoner chip next to it so that if one bulb die, the rest still light up.
3. It has extra pair of sockets on each light that you can daisy chain multiple lights and only use one pair of socket on the wall.

Sorry to hijack but....Dong how many of these would I need to light the big acrylic tank??? 3 ???

About 4 of them should do.

Dong what would you recommend for a led to use on a 180 gallon that isn't crazy expensive that could grow a mixed reef tank?
