These are the lights that i'm gonna be using for my fuge.2x36w PC with 6700k bulbs,parabolic reflectors,ballast and waterproof endcaps.Only $90 brand new w/bulbs but if your like most of us longterm reefers.Ballasts,endcaps,and such tend to get stored so i have most of the retro already.just need to order the reflectors and bulbs.They give you the option of a single unit with dual parabolic/8 faceted reflectors built in.It measures
17.5" long x 7" W x 2" tall.Perfect size for a small refuge.The dual 55w isn't that much more expensive for those that have larger fuges.
IME,with these reflectors they are the best thing thats ever happened to a PC.Ive used all 3 types of flourescents and the 3' 96wPC housed in one is brighter than a 3' 95w VHO or a 3' 39w T5.
