i found a great deal on some 50 watt hps outdoor security system lights. and upon further reading of the box it lists the color as bronze. at first i thought it meant the color of the light housing but they are black and compared to the cfl's i am using they have a bronze hue. so now i have to find out whats up with the bronze color and if it can do. so if you have any thoughts i'd appreciate it at the least got the hps ballast's real cheap and i can switch out the bulbs for the white if need be. the plants are liking it so far. heres a pic of my latest configuration. the top has my blue dream with 3 -50 watt 4050 lumens 9.99$ hps lights with one 23 watt 1500 lumens cfl, the bottom has two white rhino with two 50 watt 4050 lumens hps,and two 30 watt 2100 lumens cfl's and one 30 watt 1845 lumens cfl, my humidity is good and the temp stays around 78
