Review: Good (tight) fit. Good liight. - It's getting hard to actually find a fluorescent light tube now, at least in 17 states and Canada. So I was happy to find this one (or these two). It's a perfect replacement for the Feit tube that just burned out, though it's maybe a 64th inch too long. I had to really pry the "jaws" of the fixture apart to make it fit, but it did lock in. Now it comes on instantly. No delay or warm-up like in a lot of fluorescents. So I'm happy. I'm also glad I got a two-pack, as these things become scarcer.
Review: PERFECT REPLACEMENT - Hard to find these in a store, was so glad to find them here. Exact fit, great color and can see better now!

## Questions & Answers

**Q: Do these bulbs last as long as name brands, like GE or Sylvania?**
A: Mine lasted less than 4mo at 14hr/day usage... the original bulb that came with the fixture lasted 3yrs - disappointing - at least it was a double pack so I have another to use while I look for something better

**Q: Are these 12 volt?**
A: These bulbs require regular household AC voltage (120 volts). They have two prongs on each end, which fit into a fluorescent fixture; you press the prongs into the opening, then axially rotate the bulb 90 degrees to make contact and lock them in place.

**Q: From tip to tip (Cooper prongs) my original bulbs measure 11/7/8, will this 12 inch replacement work or do I only measure the bulb which is 113/8**
A: Yes -- I have it in my hands and it is exactly 11 7/8 tip to tip

**Q: Will these bulbs fit my t5? f24t5 or lwl18t5**
A: I would not think so. The 18 and the 24 are most likely to do with the length of the bulb. I ordered for the 12" bulbs. They fit perfect.

Perfect replacement for my small light table. Have had the light table for years. Nice to know someone still carries a replacement with all the changes in lightbulbs. Correct color balance and brightness. Good value.
