replacing ballast

[i=p/u]

Installed them, Yes. Not change a ballast on one yet. Why mate?

the last time a ballast went, it was a good height to work at and not safe.lol

so im thinking if i remember right, can you take off plastic diffuser/cover from below and drop the connections out without having to be above and take the grey lid off, meaning dropping all the light... which is awkward as hell

The one you have picutered is the type that has the plate I believe, attack it from the top. But these are 4-8 meters high so be careful. If the customer hires a tower scalfold do it, if not walk away. I've got a simlier job comming up and thats the only way I'd do it. £200+ per fitting but doesnt like spending money on fitting them saftly???

Trying to get 10 or 12 tread steps which will be perfect. No one close to me sells them. And yeah attack from top is what I knew but hoped.
