AS-IH-1013 | Replacement 9" Dual Spectrum Lamp | Ultravation

I had to replace this bulb but was con;cerned because Ultravation changed from a 12" bulb to 9". But this one worked perfectly. Thanks to Blackhawk for supplying this. HVAC companies won't sell this to you or help in any way - they want to send a Tech out to do it. But a trained Chimpanzee can do this. Not much on Youtube either. would be nice to have some instructions because it's not obvious on how to r eplace it and there are different configurations. Any way it worked fine.
