GR8 LED 2D Bulb 7W 750lm Non-Dimmable - Cool White 4000K

This is a 7W LED lamp built to the 2D form, two rectangular loops joined at a central white base, with a GR8 two pin cap that pushes straight into the lampholder. It gives 750 lumens at 4000K, a cool white light, and the specification is clear that it is not dimmable. Before ordering, turn the old lamp over and count the pins: a GR8 base carries two, while four pin 2D lamps use a different base and will not seat in this holder. The loops and the base are white throughout, so the lamp stays anonymous behind an opal diffuser.

2D lamps are the working light of hallways, stair landings, porches, garages, utility rooms and communal entrances, normally inside a bulkhead or a shallow drum fitting. At 4000K the light reads clean and neutral rather than yellow, which helps when you are looking for keys, reading a meter or judging the edge of a step; if you want something softer and more domestic, a 2700K or 3000K lamp is the warmer choice. The pack describes the 750 lumens as arriving in a narrow cone, so this lamp is happiest in a fitting that pushes light down into a space rather than one asked to glow evenly in every direction.

Wire it to a plain on and off switch rather than a dimmed circuit, since a non dimmable LED driver is not built to run on a dimmer. The energy rating is F, and the pack prints a 30 year lifespan. One box holds a single lamp, and the minimum order is 10, sold in multiples of 10, so this suits a landlord, a caretaker or a site refit better than a one off swap. It sits alongside our 2G11 PLL and 2G7 PLS LED lamps, also in 4000K cool white.

Will this fit my existing 2D light fitting?

It fits a GR8 two pin holder. Take the old lamp out and count the pins on its base: two pins means this lamp seats correctly, while a four pin lamp uses a different holder and will not fit.

How bright is 750 lumens in a hallway or garage?

It is enough for a single small to medium space such as a landing, porch or garage bay. The pack describes the output as a narrow cone, so the light lands more below the fitting than across the whole ceiling.

Can I put it on a dimmer switch?

No. The specification states it is not dimmable, so it needs a standard on and off switch. If your circuit already has a dimmer module fitted, replace it with a plain switch before using this lamp.

Which old fluorescent wattage does this replace?

The manufacturer does not state an equivalent wattage for this lamp, so no equivalence figure is given above. Compare the 750 lumens here against the lumen output printed on the lamp you are taking out.

Is an IP rating given for this lamp?

No IP rating is printed on the pack or given in the specification, so none is quoted above. The enclosure the lamp sits inside carries its own rating, which is the figure to check.

How many lamps do I receive, and is there a minimum?

Each box contains one lamp. The minimum order on this listing is 10 units, sold in multiples of 10, which works well if you are relamping several fittings at once.
