G13 LED Tube Bulb 1200mm 18W 2160lm - CCT Adjustable

This is a 4ft LED tube, 1200mm end to end, built to sit in the G13 bi-pin holders that standard T8 fluorescent tubes use. It draws 18W and gives 2160 lumens. The part that sets it apart from a fixed tube is the small slide switch at the pin end: move it and the same tube runs at 3000K, 4000K or 6500K. One product therefore covers warm white, neutral white and daylight, so the light can be decided once the tube is up and the room is in front of you rather than at the point of ordering.

Four foot is the common length in garages, workshops, utility rooms, stock rooms and cellars, and it is the size most older kitchen and office battens were built around. The colour choice earns its keep across those spaces: 6500K is a hard, bright daylight that suits a bench or a work surface where small detail matters, 4000K is the neutral white most people expect in a utility room or a store room, and 3000K sits closer to the warmer light of a living space. Where several tubes run in one room, set them all to the same position before the diffusers go back on.

The energy rating is E. The manufacturer does not state a dimmable rating, an IP rating or a wattage equivalent, and no lifespan figure is printed. Whether the tube will run on the control gear already in a fitting is not stated either, which is a question for the electrician doing the swap. The minimum order is 12, in multiples of 12, which suits a full re-lamp of a workshop or a run of battens rather than a single replacement. We also list LED replacements on 2G11 and 2G7 caps for PLL and PLS fittings, in several wattages.

Will this fit a standard 4ft fluorescent fitting?

It is a 1200mm T8 tube on G13 bi-pin caps, so it matches the holders in a standard 4ft batten. Whether it runs on the control gear already in that fitting is not stated, so have an electrician check before the old tube comes out.

How do I set the colour temperature?

A small slide switch sits at the pin end with three marked positions, 3000K, 4000K and 6500K. Set it before the tube goes into the holders, since the switch sits hard against the end cap.

Can it be used on a dimmer?

The manufacturer does not state a dimmable rating for this tube, so we cannot tell you it will dim. Treat it as a switched light unless you are able to confirm otherwise before ordering.

How much light is 2160 lumens in practice?

That is the output of one 18W tube, which is enough for general light over a workbench, a car bay or a store room. Longer rooms usually take two or more tubes spaced along the ceiling.

Is a wattage equivalent given?

No equivalent figure is printed by the manufacturer, so compare on lumens instead. Hold 2160 lumens from 18W against the output of whichever tube you are replacing.

How many do I have to order?

The minimum order is 12 tubes, sold in multiples of 12, so this listing suits a full re-lamp of a workshop or an office run rather than one failed tube.
