This is a Cool White 4000K replacement glass spiral for the 15w (75 watt) B22 / E27 Kosnic 2 part lamp. The tube connects by two pins into the adaptor (Ballast) and there is a simple to operate locking ring to hold the tube and adaptor (Do not hold the glass tube though whilst unlocking or locking a new tube).

Each tube is rated to last 10,000 hours - 10 times the life of a conventional light bulb.

These low energy bulbs also start up quicker than standard energy savers.
