Energizer LED Tube Bulb G13 600mm 9W Non-Dimmable - Cool White 4000K

This is a 600mm LED tube, two feet end to end, with a G13 bi-pin cap at each end and a frosted body that spreads the light rather than showing the diodes behind it. It draws 9W and the retail pack prints 1080 lumens, thrown across a 170 degree spread, so the light falls wide rather than in a tight line below the fitting. The colour is 4000K cool white: a clean, neutral light with none of the yellow of a 2700K lamp and none of the blue edge of a 6500K one.

Two foot tubes live in the places where people work rather than sit: garages, workshops, utility rooms, cellars, store cupboards, under a run of kitchen wall units, and in the shallow battens above a workbench. 4000K suits all of those, because it keeps colours honest when you are matching paint, sorting screws or reading a label. In a room where you relax, a warm white lamp is usually the better choice; this one is for seeing clearly. The frosted finish helps here too, softening the glare when the tube sits at eye level.

It is not dimmable, so it wants a plain switched circuit rather than a dimmer or a sensor plate wired through one. The IP rating is IP20, which means indoor, dry positions only. The energy rating is E. The manufacturer does not state which control gear the tube will run on, so read the leaflet in the box before you rewire or reuse an existing fluorescent fitting. Each unit is one tube, and the minimum order is 12, sold in multiples of 12, which suits a whole garage or a run of battens in one go. We also list 2G11 PLL and 2G7 PLS lamps in the same cool white 4000K.

Will this fit my existing two foot fitting?

It has a G13 bi-pin cap at each end and measures 600mm, so it matches the standard two foot format. The manufacturer does not state which control gear it runs on, so read the leaflet in the box before reusing an older fitting.

What old fluorescent wattage does 9W replace?

No equivalent wattage is stated on the specification or printed on the pack, so we do not quote one. Compare the 1080 lumens on the pack with the output of the tube you are taking out, which is usually printed on its end cap.

What does 4000K cool white actually look like?

It reads as a clean neutral white, brighter and less yellow than a 2700K living room lamp but without the cold blue cast of a 6500K daylight tube. It keeps paint, wiring and printed labels looking like their true colours.

Can I put it on a dimmer switch?

No. The specification lists it as non-dimmable, so it needs a plain on and off switched circuit. Running a non-dimmable lamp through a dimmer can cause flicker, buzz or early failure, so wire it to a standard switch.

How wide does the light spread?

The beam angle is 170 degrees, which is close to a full half circle, so the light washes sideways along a bench or shelf rather than dropping in a narrow band directly under the tube.

How many tubes do I receive?

One tube per unit, and the minimum order is 12 units in multiples of 12. That quantity suits fitting out a whole workshop, garage or store room, or holding spares for a run of battens.
