This 11W compact fluorescent CFL tubular light bulb by Crompton Lamps is ideal for landlords and contractors that are required to fit energy saving light bulbs in public or rented properties.
Most CFL light bulbs that feature this same double-turn design and T3 tubing come with a push-fit or 2/4 pin fitment, which prevents them from being used with fittings designed to accommodate bayonet cap light bulbs. This light bulb aims to solve that problem by mounting the same linear compact fluorescent stick design on top of a standard bayonet base.
The light bulb itself is designed to last upwards of 10,000 hours which significantly reduces replacement costs. It also produces 670 lumens despite only using 11W.
Features a BC-B22d bayonet (22mm) cap base.
