Energizer LED Tube Bulb G13 1500mm 22W Non-Dimmable - Cool White 4000K

This is a 5ft LED tube, 1500mm end to end, with the G13 bi-pin cap and T8 diameter that most linear batten and trough fittings in this country were built around. It draws 22W and puts out 2400 lumens, the figure printed on its own retail pack, at 4000K. That colour temperature reads as a clean cool white: brighter and slightly bluer than a living room bulb, without tipping into the hard blue-white of a daylight lamp. The 170 degree beam spreads light across the full width of the tube rather than throwing it in one direction.

A tube this length belongs where you want even, shadow-free light over a long run: a garage, a workshop bench, a utility room, a shed with power, a stockroom or a back office. Measure the tube you are taking out before ordering, because 4ft and 6ft fittings are common alongside 5ft and the pins will not reach in the wrong housing. Check the cap on the old tube as well. G13 pins sit 13mm apart and look quite unlike the single-ended caps used on compact fluorescent lamps.

This tube is not dimmable, so pair it with a plain switch rather than a dimmer circuit, since a dimmer left in the line can cause flicker or a buzz. It carries an IP20 rating, which is protection against fingers and solid objects rather than against water, and an E energy rating. The manufacturer does not print a rated lifespan, so we do not quote one. Each unit is a single tube, with a minimum of 12 and multiples of 12 after that, which suits relighting a whole run at once so the colour matches along the ceiling. It sits alongside our wider range of LED bulbs, which includes 2G11 PLL, 2G7 PLS and B15 candle types in the same 4000K cool white.

Will this fit a standard 5ft batten?

It uses the G13 bi-pin cap and the T8 tube form at 1500mm, which is the usual 5ft linear size. Measure the housing and count the pins on the old tube before you order.

Do I need to change anything in the fitting first?

The manufacturer does not state whether the tube runs on existing control gear or needs the fitting altered, so have a qualified electrician check the batten before installation rather than assuming either way.

How bright is 2400 lumens over a 5ft run?

It is a working level of light rather than a soft one, spread over five feet by a 170 degree beam, which suits benches, walkways and storage racking where you need to see detail.

What does 4000K cool white actually look like?

It is a neutral white with no yellow cast and no strong blue edge. Colours and labels read accurately under it, which is why it is common in garages and stockrooms.

Can I run it on a dimmer switch?

No. The specification lists it as non-dimmable, so it should be wired to an ordinary on and off switch. Leaving a dimmer in circuit risks flicker, noise or early failure.

Which fluorescent wattage does it replace?

The manufacturer does not print an equivalent wattage, so we will not quote one. Compare the lumen figure on your old tube with the 2400lm stated here to judge the swap.
