will Icecap 430 run 46.5" VHO bulbs?


New member
today I bought replacement VHO bulbs and they are 46.5" instead of 48".

I moved the end caps closer, put in new bulb, turn on the light and the new bulbs don't light... anyone know what's up?
I put the old bulbs back in the end caps and it lit up... so somehow, the Icecap and these 110W VHO short bulbs aren't happy.
