180W is a small one. Yeah, I think you will have much less work to do after upgrading the lights.:p BTW, do they still sell 300W? Coz I have heard about Mars Hydro old model 300W almost sold out, hard to find a new one on ebay or amazon. Anyway, if you want, you can contact my seller, she is a sweet girl, so patient to asnwer to my questions, maybe she can help you to choose the best one. She gave me a friend price, I think i paid the lowest price to get my reflector...... If anyone needs her email? ;)
