Description
This is a 5W LED replacement for the four pin 2G7 compact fluorescent lamp, the short twin tube type usually written PL-S or PLS/E. It gives 700 lumens at 4000K cool white, and the retail pack rates it as a replacement for an 11W fluorescent. The four pins sit in a white moulded base below a pair of parallel tubes, so it goes into the same lampholder the old lamp came out of. It is not dimmable, and the manufacturer gives it an energy rating of D.
Fittings that take a 2G7 lamp tend to be compact and purpose built: wall and ceiling bulkheads on landings and in corridors, stair and porch lights, desk and machine lamps, and the slim amenity fittings found in utility rooms, garages and workshops. 4000K is the neutral white that sits between the yellow of a 2700K bulb and the blue edge of daylight, so it reads clean and even rather than cosy. That suits working light, circulation space and anywhere you want colours to look true. The pack quotes its 700 lumens measured in a sphere, which tells you the output spreads around the tubes rather than firing forward as a beam.
Before fitting, read the warning printed on the pack: the lamp is not compatible with an electronic ballast, and the pack states that the ballast must be removed and the fitting rewired to run direct from the mains, with installation carried out by a qualified electrician. The pack prints a 30 year lifespan. Each box holds one lamp, and the minimum order is 10, sold in multiples of 10. We also stock 2G7 lamps at 3W and 4.5W, and 2G11 PLL lamps from 8W up to 24W.

Frequently Asked
Will this fit my existing 2G7 lampholder?
Yes, provided the old lamp has the four pin 2G7 base used on short PL-S and PLS/E compact fluorescent lamps. Check the base marking before ordering, because the similar looking PLL lamps use a 2G11 cap.
Does the fitting need rewiring first?
The pack warns that the lamp is not compatible with an electronic ballast, and says the ballast must be removed and the fitting rewired to run direct from the mains, with the work done by a qualified electrician.
How does 5W compare with the fluorescent lamp it replaces?
The pack rates it as a replacement for an 11W fluorescent of the same type, and the LED gives 700 lumens, so you should see a similar level of light from roughly half the wattage.
Can I run it from a dimmer switch?
No. The specification lists it as not dimmable, and the pack carries a non dimmable icon, so it should be wired to an ordinary on and off switch rather than any dimming control.
What does 4000K cool white actually look like?
It is a neutral white with no yellow cast and no strong blue. Colours look true under it, which is why it is the usual choice for corridors, stairs, utility spaces and task lighting.
Is an IP rating given for this lamp?
The manufacturer does not state one, so treat the lamp as unrated and rely on the rating of the fitting it goes into. Keep it to dry, enclosed or open indoor fittings.
