Flouresent lighting in ceiling, when turned on it takes a while before they come on and then only 2 come on?
Glyndwer P asked:
The bulbs/tubes that don’t come on, would they be burnt out or would it be the ballasts? It’s a drop ceiling “T” bars and has the flexable plastic 2×4 frosted panels that sit on the “T” bars. This is the lighting in my kitchen.

Most likely one or two of the bulbs are bad
Replace the ones that don’t come on. [who] rester
First,,,try replacing the bulbs that will not come on. If after that they do not come on, then the ballast is bad. [who] bugear001
With conventional choke & glowstarter, it often applies that:
1. If the Starter has failed, the tube will remain in heater warmup (ends glowing), this will sap the life of the tube quite badly, even if the starter is replaced.
2. If the tube is making repeated attempts to start, it usually means the tube has aged to the point that its resistance is too high to prevent the starter retriggerring. Disengaging the starter at the right moment will often enable the tube to remain lit, but an aged tube will flicker even if it remains lit.
3. The least common cause of total non-starting, is a failed ballast.
For electronic ballasts, it can be different.
Finally, as an improvement to the conventional starter system, you can get electronic starters. On supported tube types, they generally result in a much faster and surer start with less wear on the tube heaters, but some tubes just do not agree with them. [who] theradioham
Check the ballasts. [who] karen j
Always try the easy fixes first. Replace the bulbs. If that doesn’t work then look at the starters if you have them and then the ballast. [who] oil field trash
