Question about ballasts

I didn't bring them to work, but they are an electronic ballast for sure. On the specs it says that it works for T12's and T8's and CF's but there is no mention of T5's anywhere on the spec sheet. Maybe the ballast was on the shelf for a few years and T5's were too recent for them???

The T5 will work but you might end up overdriving them and shortening their llife. Electronic ballasts you might get away with.

i would have to say you would be under driving them and they will not fire due to the fact that a standard VHO 4' T5 is 54 watts (which i would think is in your fixture), a standard 4' T8 is 34 watts and a standard T12 is 40 watts , there for your ballast will not supply enough initial in rush to fire the lamp.
