Description
This is an LED replacement for a 2G11 four pin PLL fluorescent tube. It draws 8W and gives 1000 lumens at 4000K, a cool white, and the pack rates it as a replacement for an 18W PLL. The form is the familiar twin parallel tube on a single white base, with four pins in a row, so it drops into the same lampholder the old fluorescent came out of. Light comes from the whole length of both tubes rather than a single point, which is what makes this shape useful in shallow fittings.
PLL lamps turn up in places where a fitting is long and thin and there is very little depth to play with: under cupboard strips, slimline wall fittings, task lights over a workbench, desk and display lights, and the recessed panels used in shops and offices. At 4000K the light reads as neutral and crisp rather than yellow, which suits a kitchen, a utility room, a garage, a hallway or a home office, and it keeps white paint and stainless steel looking white.
One thing to check before you buy. The pack states that the lamp is not compatible with an electronic ballast, so the existing ballast has to be removed and the lampholder wired directly to the mains, and it says that work must be done by a qualified electrician. If you are not sure what is inside your fitting, look before you order. It is non-dimmable, so pair it with a plain on and off switch rather than a dimmer plate. The energy rating is E, and the pack prints a 30 year lifespan, equal to 30,000 hours. Each box holds one lamp, and the minimum order is 10, sold in multiples of 10. We also stock 2G11 PLL lamps at 12W, 18W, 20W and 24W in the same cool white 4000K.

Frequently Asked
Will this fit my existing 2G11 fluorescent fitting?
The base is a 2G11 four pin type, so it sits in the same holder as an 18W PLL fluorescent tube, but the wiring behind the holder has to be checked first.
What does the ballast warning on the pack actually mean for me?
The pack states the lamp will not run on an electronic ballast. The ballast must be taken out and the holder wired direct to the mains, and the pack says a qualified electrician should do that work.
How much light does 8W give compared with the tube it replaces?
It produces 1000 lumens and the pack rates it as an 18W replacement, so you get comparable output from well under half the wattage.
What does 4000K cool white look like once it is in?
It is a neutral, slightly crisp white with no yellow cast, which is why it works well over worktops, benches and anywhere you want to see detail clearly.
Can I put it on a dimmer switch?
No. The specification and the pack both mark it non dimmable, so it needs a standard on and off switch rather than a dimmer plate.
Is an IP rating given for this lamp?
The manufacturer does not state an IP rating for it, so we make no claim about water or dust protection and would keep it to ordinary dry indoor fittings.
