3.5W Maintained Emergency Bulkhead - Daylight 6500K

A maintained emergency bulkhead with an integrated LED board rated at 3.5W and a colour temperature of 6500K, which is the cool blue-white end of daylight rather than anything warm. Maintained is the part worth understanding: the fitting is lit during normal use and stays lit on its internal battery when the mains supply drops, so it earns its place as everyday light instead of hanging dark on a wall until something goes wrong. The housing is white with a clear ribbed diffuser secured by metal toggle clips, and the LEDs run the length of the body so light spreads along a corridor rather than pooling in one spot.

It suits corridors, stairwells, landings, storerooms, plant rooms and back-of-house routes in offices, shops, workshops and blocks of flats, anywhere a route needs to stay readable when the lights go out. The flat rectangular form sits close to the surface and takes up little depth, so it clears door swings and shelving. Because no IP rating is given by the manufacturer, treat it as a fitting for dry, indoor positions and keep it away from damp or exposed locations.

6500K daylight gives a hard, clear light that keeps signage and floor edges legible, and it sits deliberately apart from the warmer light of a living room so an escape route reads as one. The manufacturer does not state a rated duration, a lumen output or whether the driver accepts dimming, so check the paperwork in the box before you commission the fitting or add it to a test schedule. Each unit is a single fitting, and the minimum order is 12, sold in multiples of 12, which suits a full floor or a refit rather than a one-off replacement.

What is the difference between maintained and non-maintained emergency lighting?

A maintained fitting is lit during normal running and stays lit on its own battery if the mains supply fails. A non-maintained one stays dark until the supply drops, then lights.

Can this be dimmed on a standard dimmer switch?

The manufacturer does not state whether the driver accepts dimming, so we cannot say it is dimmable. Treat it as a fixed output fitting unless the instructions in the box say otherwise.

Where can I safely fit it?

No IP rating is stated by the manufacturer, so keep it to dry indoor positions such as corridors, stairwells, storerooms and plant rooms, away from damp, splashing or exposed outdoor locations.

What does 6500K daylight actually look like on a wall?

It is a crisp blue-white rather than a warm yellow-white, closer to overcast daylight. It keeps signage, steps and floor edges easy to read, which is the point on an escape route.

How many do I have to buy?

Each unit is one fitting, and the minimum order is 12 units, sold in multiples of 12. That works well for a full floor, a stairwell run or a planned refit.
