    Sylvania T12 Instant Start Light Bulbs

    Genesis Lamp offers a wide selection of fluorescent light bulbs. We carry Circleline fluorescent light bulbs, specialty fluorescent light bulbs and compact fluorescent light bulbs. We'll help you find the right light bulb for all of your lighting needs. A fluorescent light bulb produces less heat, so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs.
