The manufacturers claim that the electronic ballasts burn the bulbs brighter and that the bulbs will last longer. They run cooler and use a little less power than the core/coil ballasts. The core/coil ballasts are less expensive initially though and will do a fine job. IMO
, the electronic ballasts are probably a better deal in the long run. If you're willing to DIY
some of it though, you can save a lot of money up front with the standard ballasts.
Most bulbs will light on a probe start ballast. AFAIK
, all of them will light on a pulse start ballast. I believe the Radium bulbs require the pulse start and there may be some others.
I don't have any firsthand experience with the Hello Lights reflector...I can tell you that Hello Lights has an excellent reputation for quality products and I wouldn't hesitate to try one.
