G13 LED Tube Bulb 1800mm 30W 3400lm - Cool White 4000K

This is a 6ft linear LED tube with a G13 twin pin cap at either end, drawing 30W and giving 3,400 lumens at 4,000K. G13 is the cap standard used on T8 linear fluorescent tubes, so the figure worth checking before you order is the length: this one measures 1800mm, the size usually sold as 6ft. Light leaves it across a 170 degree beam, the wide and even spread that suits a long ceiling run rather than a directed pool over one spot.

Cool white at 4,000K is a neutral working light rather than a cosy one, and it keeps colours looking true, which matters when you are reading labels, matching wires or sorting stock. It earns its place in garages, workshops, utility rooms, stores and long corridors, and in kitchens where a warmer tone would flatten the contrast between surfaces. Because a 6ft tube covers more ceiling than a 4ft one, a run of them lights a large space with fewer fittings and fewer connections. The IP20 rating means no protection against dust or water, so it belongs in dry indoor fittings.

It is not dimmable, so wire it to a plain on and off switch and leave dimmer modules out of the circuit. The energy label puts it in class E and gives consumption as 30 kWh per 1,000 hours, the number to work with if you are costing a run that burns all day. Each unit is a single tube, and the minimum order is 12 sold in multiples of 12, which suits relamping a whole run at once rather than chasing one failed tube. It sits alongside our wider range of non-dimmable 4,000K cool white lamps, including 2G11 PLL and 2G7 PLS types.

Will this fit my existing 6ft fluorescent fitting?

Measure the old tube end to end and look at the cap. This one is 1800mm with a G13 twin pin cap at each end, so it suits fittings built around a 6ft T8 tube of the same cap type.

Does it need a starter or a particular type of control gear?

Energizer does not state which control gear the tube is designed to run on, so check the wiring details printed on the retail pack against what is already in your fitting before installation.

How bright is 3,400 lumens across a 6ft tube?

It is a working level of light spread over a long fitting rather than concentrated, and the 170 degree beam pushes it wide, so one tube covers a good width of floor in a garage or store.

What does 4,000K cool white actually look like?

Neutral and slightly crisp, sitting between the yellow of 2700K and the blue of 6500K. Whites stay white and colour matching is easier, which is why it suits task areas rather than living rooms.

Can I put it on a dimmer?

No. The specification gives it as non dimmable, so it should be switched on and off only. Running a non dimmable lamp on a dimmer can cause flicker or shorten its working life.

Is an old-style fluorescent wattage equivalent given?

The manufacturer does not state an equivalence figure on the specification or the pack, so compare on lumens instead: 3,400 lumens is the number to hold your current tube against.
