I have the JEBO 48in 220w (4x55w). It works fine (one year so far...knock on wood), but you should plan on doing something about the heat buildup. The ventilation in the JEBO IMHO is completely inadequate. I cut a hole in the top and installed a small fan - which solved the problem nicely.
Definitely a great advice! This is the sort of thing I was looking for from people with experience with this product So ventilation is one issue. Got it! Any more from others? Thank you all, people!
