Circleline Fluorescent Light Bulbs

Circline fluorescent light bulbs, those circular tubes of light, are some of the longest-lasting bulbs on the market. The T9 Circline fluorescent replacement bulb, one of the most popular replacement bulbs, fits into virtually any fixture that would traditionally use an incandescent light bulb. Such replacement light bulbs offer an average of 10,000 hours of light, meaning that they will last an average of seven years if used up to four hours a day.

Genesis Lamp stocks a full line of Circline replacement light bulbs, including Circline T9 fluorescent light bulbs. These products work with both instant start and preheat ballast-type light fixtures.
