Kids had been complaining about how dark it was in the basement, so I went an bought a case of tubes and started replacing.
After puting in 28 new tubes, 4 to a fixture, I can say that the basement is only marginally brigher- most fixtures ( all on the same switch) have only two bulbs lighting. Wiring issue? Balast? These fixtures (4 footers for suspended ceiling) are only about 8 years old- can these ballasts be bad already? Ballasts about $30, whole fixture about 45...just replace the fixture on the assumeption that 2nd ballast is about fried too?
Tubes: I always thought that the pins should be parrallel to eact other end to end, but this is NOT the case on all of these Sylvanias bought from Lowes in a commercial pack- some look to be off by 10 or 15 degrees. Is this a problem?
These are T12 tubes....can T8 tubes fit in the same fixture?
In one room, with two fixtures- flip the switch, only one fixture lights. Flip again, other lights. Keep flipping, both will light. None of these fixtures have starters.
What do you think?
