GE makes a 55w(equivalent of 200). Mine is Soft White(2700k), 3860 lumens. I'm currently using 3 of them along with 4 32w 4' tubes @ 2600k in a closet. I hope that light works for you. I bought mine @ Walmart for about $12. I hear you can generally expect 1/2g per watt. Not sure if it's correct.? Good Luck!:smokin:
