Product Description

Crompton Lamps 11W ES-E27 LED Thermal Plastic GLS


The GLS bulb’s universal shape enables these LED versions to retrofit directly into existing fixtures with minimum effort.

They are distinctly more efficient than the incandescent versions they are designed to replace, consuming only 11W of power yet producing light of an equivalent brightness to 75W filament bulbs. This remarkable efficiency - when considered alongside each bulb’s vastly improved longevity and reliability - can potentially reduce your lighting bill by up to 90% whilst simultaneously reducing carbon emissions.

A thermal plastic shell encases the bulbs and dissipates heat away from their components more effectively than existing materials, thereby extending their longevity even further. This results in a range of bulbs that is reliable, green, elegant and easy to install.

Delivery & Returns


Last postage dates for mainland UK.

Standard Delivery - 12 pm Wednesday 19th December*

*Any order placed for an in-stock item by 12 pm Wednesday 19th December will be dispatched by standard Royal Mail in time for their last postage cut off. Whilst this does not guarantee you Christmas delivery, as long as there are no delays with the postal service then your order should be with you in time for Christmas.

Next Day Delivery - 1 pm Thursday 20th December*

*Any order placed for an in-stock item by 1 pm Thursday 20th December will be dispatched for delivery on Friday 21st December.

If you arrange an urgent delivery, there is still no absolute guarantee that it will be delivered the next day, as, despite our best efforts, courier failure/errors and ‘acts of god’ may still occur. Therefore while every effort will be made to have your goods delivered on time, LightBulbs Direct Ltd accepts no responsibility for any costs incurred as a result of delayed delivery.

If delivery is delayed excessively, we will do our utmost to inform you as soon as possible. We are happy to give you the option of purchasing alternative items or receiving a full refund of any payments that you have made. If we are unable to deliver within 28 days of ordering, we will always give you the option of receiving a full refund of any payments made.

Delivery charges quoted are for UK mainland destinations only using our standard delivery methods. For deliveries over 1.5kg to the Scottish Highlands and Northern Ireland, off-shore destinations and express services, please contact our sales office for a quotation.

Please note that most orders weighing in excess of approximately 1.5 kg and any valuable deliveries are delivered by courier and will require a signature on delivery. Please ensure that you provide a delivery address where someone will be available between 9.00 and 17.00 Monday to Friday to accept delivery. If our couriers are unable to deliver an order due to the address being unmanned, a card will be left asking you to contact them directly to arrange re-delivery. If no contact is made within 2 days the order will be returned to us and a re-delivery charge will be levied to cover our re-delivery costs.

Please make sure that you always order your light bulbs to arrive well before you need them as costs of cherry pickers and sub contractors are always more expensive than the light bulbs themselves.
