I got two different extra lights for my 400 hps.I dont know if there are different spectrums in the hps bulbs,or is the spectrum pretty much standard?I got one that is made by Philips,it is called Ceramalux with Alto lamp tech. The other one is just a hps bulb.No company name on it.The ONLY two things thats on the lable is 400 watt HPS and assembled in China.On the bulb it says LU 400.Is either one of these ones good?Both of them? or none of them?Thanks everyone for stopping in and looking at this thread.:aok:
