Replace your old halogen lighting with this 78mm length Crompton Lamps R7s LED bulb, a compact, double-ended linear LED bulb designed as a direct halogen bulb replacement. With a standard R7s base and clear glass finish, it retrofits into many existing fittings for a quick, energy-saving upgrade.
This 6W LED bulb delivers the brightness of a 50W halogen equivalent, producing 610 lumens of crisp 4000K cool white light. It provides instant full brightness with a wide, 360° light output, making it an excellent choice where strong, even illumination is needed.
Ideal as an LED floodlight bulb and for common R7s applications such as uplighters, parent and child floor lamps, security lights and display cabinets. With an average rated life of up to 20,000 hours, it helps reduce maintenance and replacement costs compared with traditional halogen lamps.
Upgrading from Halogen to LED? Switching to LED offers massive energy savings, but the physical dimensions do differ. Traditional halogen tubes feature a minimal 8mm profile, while this high-output LED version has a diameter of 20mm. This extra width is essential for the built-in LED driver components. To avoid installation issues, please verify that your fixture has enough depth to take a 20mm bulb, especially if you are replacing lamps in older style exterior floodlights or interior uplighters.
Any LED or LED Smart light bulb bought from Lightbulbs Direct carries a 24-month warranty.
If you should purchase an LED light bulb from Lightbulbs Direct 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.
This product is also covered by a manufacturer's warranty for a period of 3 years from date of purchase. Please visit the manufacturer's website for further details.
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.
