We have a few flourescent lights out at the office. Each light holds 4 bulbs (T8 type). Each light that is burnt out has all 4 bulbs out. I just put 4 new bulbs in one of the lights and not one worked...not one worked as I was putting them in. I took out all 4 [supposedly] burnt out bulbs. As I was putting the new ones in, one by one, I thought, "hmmm, maybe I need to have all 4 bulbs in for them to work" (like with some Christmas lights). No light. Before I go climbing back up on a ladder and put 4 new bulbs to replace 4 [supposedly] burnt out bulbs, is there possibly something wrong with the light unit itself? And, yes, I have the two pins on each end in the socket and the bulb turned into place.

could be a bad starter/s in the fixture.

Yes.

Light ballasts have been known to crap-out after a time.

how many cincy folk does it take to change a lightbulb?

there are not enough left in the state after new york just punched their lights out.

check all the breakers, depending on how they were wired for the building all of them in the same place may not be on the same breaker. In some buildings there are groups that are set to stay on all night for safety.

Buy a new unit but check with Ram27 first.

It's the ballasts.

3 units (that I'm aware of) with all 4 bulbs off in various areas of the office building (one story building).

Ballasts.

Need to be changed is what is sounds like. I have 50 or so in my store and need to be changed on occasion.

Not a bid deal, but label your wiring before you swap, and suggest bringing the ballast in to the local ACE to make sure its compatible if an older unit.

The building is 1 year old. 😕 Thanks for the advice all.

#4 Dammit, you stole my idea. Well, I'm going to use it anyway, since I had a different punchline (nothing wrong with yours, I just had a different one).

Q: How many Cincinnatians does it take to change a lightbulb?

A: Apparently more than one.

Newer light fixtures have crap ballasts compared to the old days. Some starting to go out in a year is not hard to believe.

Dave, be careful checking it. If it's like the older ones when they go bad, it might be hotter than hell if the switch has been left on.

It’s the ballasts.

ayup...will take a look at the ballasts at the end of the day...or just call an electrician. 🙂

Hey, has anyone mentioned to check the ballasts?

Will throw this out there in case it's not been mentioned.

It sounds like the ballast.

(ahem)

It is definitely the ballast. No ifs ands or butts about it!! Only four things that can be wrong when a floresent doesn't come on.

1. Power

2. lamps

3. Sockets

4. ballast

The more I think about this, the more I think you should consider the possibility that it might be a problem with the ballasts.
