Its long 10,000 hour life means that once the light bulb is installed, it will be years before it needs replacing again with a lifespan of up to 5 years. It can be used outdoors when installed in a suitable IP65 rated light fitting.

Suitable for dimming - separate ballast/control gear required. Suitable for use in emergency luminaires.

Fitted with a GR10q 4-pin square push fit 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.
