I purchased two dimmable drivers, 2 reostats(dimmers), 14 x 3W LED, optics, heatsink, hanging kit and wiring for $105 shipped. It's DIY so you will need to learn how to solder but you cannot beat the price. The LEDs are Bridgelux, the outfit always throws in extra bulbs so my 14 bulb purchase ended being 16. You can buy complete DIY kits up to 120 emitters
nano-reef.com is where I found them and everyone there who has purchased them is as happy as I am. Check it out here:
