- Will this fit my magnifying lamp?
- Only if the lamp takes an 8-inch T9 circline tube with a 4-pin or 2-pin base matching yours. Check the old bulb's markings and pin count before ordering.
- Is 1,250 lumens bright enough?
- Yes for a desk, craft or vanity fixture. It is roughly equal to a 75W incandescent bulb in perceived brightness.
- How long does one bulb last?
- The rated life is 16,000 hours, about 5 to 7 years at a few hours of daily use. Frequent switching shortens fluorescent life.
- Is this an LED?
- No. It is a fluorescent tube and contains a small amount of mercury, so recycle it at a hazardous-waste drop-off rather than in household trash.
- Does it work in cold rooms?
- It will start, but fluorescent tubes are dimmer and slower to reach full output in cold spaces. LED replacements handle cold better.
- When is the best time to buy?
- No price was given, so compare the current price with its recent range. Two-packs often cost less per bulb than singles.
