PC lighting without ballast
On my 20g I use two Panasonic 23 watt 5000k PC's(lights don't look green or yellow at all) with 1420 lumens and compared to 90 watt. These bulbs were $19.99 and are guaranted for 18 months or bulb will be replaced over the counter if they stop working or anything besides being shattered. These PC's are SWEET!!! Definatly good for NANO's and refugiums. ;)
