Hello,

Can enyone tell me if these starter units(see link) could overdrive my present lighting. I was thinking of buying the Hagen Glomat Double Starter Unit for 40 watt, would this work?.

I currently have two 24inch 20watt tubes in my hood but would like to try over driving them.

I am not competent with electricity so would prefer to buy something ready made.

Thanks
Joe Barry

Just taking a quick look at their description, I believe what they are calling a "Starter Unit" is an Electronic Ballast. It is quite possible that you could use the 40watt electronic ballast to overdrive your 20w bulbs but the ballast could also be load-sensing and you might not get a single extra watt of light. Or it might not have a current limiting device and burn out when presented with the low-resistance 20w bulb instead of the longer 40w tube it was expecting to see.

If it hasn't been tried before, and you're not competent with electricity, I wouldn't recommend utilizing those ballast any other way than the manufacturer recommends.
