Prolite GLS LED Light Bulb E27 18W Daylight Opal (125W Eqv)


Discover the brilliance of the Prolite 18W LED GLS light bulb. This bulb is a direct substitute for 33W CFL light bulbs, offering remarkable savings on energy while minimizing the hassle of frequent replacements.

Built with advanced LED technology, it consumes just 18W to generate the same 2000lm as a 125W bulb, boasting an impressive energy-efficiency ratio of 111lm/W, significantly reducing electricity consumption.

Designed with a lightweight thermal plastic shell, it effectively disperses heat, extending its lifespan and reducing strain on its components. With an incredible 20,000-hour lifespan (11 years with 5 hours of daily use), you'll spend less on replacements and less time changing bulbs.

Moreover, these bulbs' efficiency and longevity can cut your lighting costs by up to 45%. Opt for the Daylight (6500K) option for natural, accurate lighting ideal for task areas, retail displays, and workplaces.

Experience instant brightness without any waiting time, unlike older energy-saving technologies. Plus, its universal fit (80mm diameter, 155mm height) allows easy installation into any existing ES-E27 fixture, from small household fittings to large commercial setups.

Here at SimplyLED, 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 LED or LED Smart light bulb bought from SimplyLED carries a 24-month warranty.

If you should purchase an LED light bulb from SimplyLED and have it fail, break or develop a fault at any point within the timeline 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.
