I'm barely scratching the surface of LED technology, but it excites the heck out of me.  I'm considering these LED's for my 1st build over a FW 155 bowfront. 

http://www.dhgate.com/5m-cold-white-smd-5050-waterproof-ip65-flexible/p-ff8080812c87ca07012c9afc43e35d60.html#an0802-pro-2

They aren't nearly as bright as u guys are using for corals (800-900 lumens/meter[60 leds]), but I bring it up here wondering if they would be a viable option for moon lights or something.  They are prestrung very close together (20/ft) on flexible, cutable, self-adhesive strips.  If my math is correct (and I wouldn't trust itWink) it only uses 1.2w/foot.  They have 120 degree optics.
If I order these, I would use (2) 6' strips or 240 leds.  what's the cheapest driver I could use?
Oh, and if u think these lights are garbage, feel free to say so.   Smile
BTW how do I make that site a hot link?

I have used similar LED strips to make moonlight before and they didn't require a separate driver. They circuitry is all integrated but they do require a regulated 12v voltage (you can't just use a standard ac/dc adapter because they output variable voltages).

Thanks!
What should I use for converting to 12v?
