I've read a couple of times before that HQI type bulbs put out more light than the standard type of bulb. Is is true that a 250 HQI has an output near that of a 400 w mogul? Also does anybody know if the IceCap 250w ballast will work for 250w HQI. I have two of them, one less than a year old, another almost 2 years old. Have the IceCap ballasts always been ale to run either HQI or others? I think they can run either but I just wanted to check. Last question...does anybody know of a spider type reflector for HQI style bulbs? I could only find socket type at hellolights.com. Thanks everybody.
