What's the general lifespan of the bulbs / ballasts?
I've read a few where they go really quite quickly.
I bought a set last December. Didn't use them much as i got attention from the law.
Sold them to a member here & he PMd me a few weeks ago saying one or both ballasts had gone (can't remember which now).
8-9 months isn't very long i'd have thought. But i know this isn't the only set that've gone quite quickly.
