I'm a fan of LED's, especially on something small like that. No radiant heat. For about $160, you can get (12) Cree 3Wm driver, heatsink, etc. shipped from reefledlights.com. You'd want a dimming circuit, too (LED's push some serious light, esp to a nano). $30 at rapid LED, $10 for 10VDC regualted power supply. Around $200 total and can keep whatever you want. Some time in building them, but I'm sure someone local can help with that.
