20W IP20 LED 4ft Emergency Single Batten - Cool White 4000K

A batten is the plainest way to light a working space properly, and this one is a 4ft (1200mm) unit drawing 20W and giving 2,400 lumens. The LEDs sit behind a long white diffuser that pushes the output out over a wide 120 degree beam, so the light lands evenly along the length of the fitting rather than in hard pools underneath it. The light source is integrated, so there is no separate tube to buy now or replace later. The housing is white, the gear tray is hinged and screwless, and an emergency function is built in.

At 4,000K the light is cool white, cleaner and crisper than the warm white most living rooms use, and it is the usual choice for garages, workshops, utility rooms, stock rooms, corridors and small commercial units where you need to see detail clearly. Two or three in a line will cover a double garage or a long store without dark gaps between them. The IP20 rating means no protection against water, so keep this one to dry indoor spaces; for a damp outbuilding or a wash bay an IP65 non-corrosive batten suits better, and we list those in 5ft and 6ft lengths.

The emergency function is the reason to pick this over a plain batten: when the mains supply fails, the fitting keeps a reduced light running from its own internal battery, which is what stairwells, corridors and escape routes generally need. The manufacturer does not state the emergency duration, so confirm what your building requires before you order. It is not dimmable, so wire it to an ordinary switch rather than a dimmer plate. The body carries an IK06 impact rating and the energy class is D. It is sold singly, one fitting per order.

What happens when the power goes off?

The emergency gear takes over and runs the fitting at a reduced output from its own internal battery. The manufacturer does not state how long that output lasts, so check your building's requirement first.

Do I need to buy a tube to go in it?

No. The LED board is integrated into the fitting, so there is nothing to order alongside it and no lamp to change during its working life.

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

It is a clean, slightly crisp white, brighter in feel than the 2,700K warm white used in living rooms. It suits garages, workshops and stores where you want colours and detail to read accurately.

Can I run it from a dimmer switch?

No, this fitting is not dimmable. Wire it to a standard on and off switch; putting a non-dimmable driver on a dimmer plate can cause flicker, buzzing or early failure.

How many will I need for a garage?

At 2,400 lumens each, two run end to end usually light a single garage comfortably, and three suit a double. Space them evenly across the ceiling rather than crowding them over one bench.
