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, which lends the light bulb an excellent A energy rating.

Features a BC-B22d bayonet (22mm) cap base.

Here at Lightbulbs Direct, we want you to be able to buy with confidence both in ourselves and the products we sell. With this in mind, a number of our bulbs carry a specific warranty that ensures you can do exactly that.

Any Energy Saving Compact Fluorescent light bulb bought from Lightbulbs Direct carries a 12-month warranty.

If you should purchase an energy saving compact fluorescent light bulb from Lightbulbs Direct and have it fail, break or develop a fault at any point within the timelines stated above from the date of purchase, we will happily replace the item or offer a full refund, depending on your wishes.

In instances where large numbers of bulbs fail within a relatively short period of time, we may ask you to return them to us so that they can undergo testing to identify any potential issues.

What doesn't our warranty cover?

In any instance where your bulb has developed a fault, we will do our utmost to replace it or offer a full refund (provided the item is still within its stated warranty period). However, if it becomes apparent that the product has been misused, tampered with or modified in any way, we will view this as having voided its warranty.

'Misuse" includes, but is not limited to, incorrect operation by the user, use of non-dimmable bulbs on a dimmable circuit or connection to or operation with an unsuitable power supply. 'Tampering' or 'modification' can be interpreted as any activity designed to alter the product in such a way that it can be used in a manner that wasn't intended by its original design. This can include rewiring, removing plugs, home repairs or changing components. Unfortunately, we won't be able to replace any item that has undergone any such process.

If you have any further questions about our Warranty or Returns Policy that aren't addressed on this page, please feel free to contact us.
