My "Radionic Industries" Ballast does say "For one 30w or 40w lamp".
I do want to get a bulb, but I don't know what bulb would be suitable for collection use!  ???


According to some comments,*
1. F30T12 will not work good as they will overheat.
2. F40T8 will have trouble starting as the voltage drop is high.
(* is to address that circline comment, The fixture connected only takes linear tubes)
F30T8 or F40T12 may work I believe.


If anyone wants measurements, There is a 35 inch space between the two tombstones.


Just asking so I don't accidentally burn my house down!

I believe that F30T8 fluorescent tubes might work best on this ballast since ballasts like these tend to underdrive F40T12 fluorescent tubes quite considerably.

Here's a snippet from their catalog.  It's intended for 30W T8, 40W T12, and 32W circline.

Hmm interesting. It seems like ballast factor isn't listed on there so if you want to figure out which lamp does it drive best, you'll probably need to get a clamp meter and measure lamp current.

In general, I would consider a ballast to be a good ballast if it runs its intended lamp within 10% of its rated current and if it does not overheat.
