My light won't turn on.
It's a 400w Lumii Black plastic ballaSt & a euro wing (cheap) reflector and bulb.
When I plug it in, I hear a very faint buzzing from the ballast which lasts around 5 seconds and then stops.
I tried changing the bulb, fuse in plug and also checked all connections are secure. (stupidly checking the ones on the reflector whilst still plugged in). This does lead me to believe that it must be the ballast as surely if there was power going to tthe light, I'd have had a shock.
I don't know what to try next.
