25W IP65 5ft LED Emergency Batten - Cool White 4000K

This is a 5ft LED batten, 1500mm end to end, drawing 25W and giving 2,800 lumens at 4,000K. That Kelvin figure is the useful one to check: 4,000K is a cool white, cleaner and less yellow than a warm lamp, and it is the light people ask for when they need to read labels, part numbers and print without squinting. The body is rated IP65, which means the enclosure is sealed against dust and against water jets rather than only splashes. Along the front sits a ribbed diffuser that spreads the output down the whole length, so you get a band of light instead of a hard bright line. The fitting also carries an emergency function, keeping light going from its own internal supply if the mains drops out.

A 5ft batten is the workhorse of spaces a pendant cannot help: garages, workshops, plant rooms, stores, loading bays and farm buildings where dust and damp are part of the room. The sealed rating is what lets it live in those places, and the emergency function is what makes it worth fitting along a corridor, a stairwell or an escape route, where the light needs to stay on long enough for people to leave safely. Two or three in a line will cover a double garage or a small workshop; measure the run first, because 1500mm plus clearance at each end is what you need on the ceiling.

The metal toggle catches along the side hold the diffuser onto the housing, and a sealed enclosure keeps dust away from the light source, which on an open fitting is what dulls the output over the years. It is not dimmable, so wire it to a plain switch rather than a dimmer plate. The supplier rates it E on the A to G energy scale. It is sold as one batten, ordered singly, so you can buy the number your run needs.

What happens if the power goes off?

The fitting carries an emergency function, so it keeps light going from its own internal supply when the mains drops out. The record does not state a duration, so we do not quote one.

Can I put it on a dimmer?

No. The specification lists it as not dimmable, so wire it to a plain on and off switch rather than a dimmer circuit.

What does IP65 actually protect against?

The first digit, 6, means the enclosure is dust tight. The second, 5, means it withstands water jets from any direction, not just the odd splash.

How long is it, and what clearance should I allow?

It is a 5ft batten, 1500mm end to end. Allow a little more than that along the ceiling so the end caps clear any wall or upstand.

How does 4,000K compare with a warm white lamp?

4,000K reads as a clean neutral white. Set beside a 2,700K warm white lamp it looks brighter and far less yellow, which suits working spaces better than living rooms.

Which old fluorescent tube does this replace?

Neither the specification nor the packshot states a wattage equivalence, so we do not publish one. Compare on the lumen figure instead: this batten gives 2,800 lumens.
