Astim 400x100 8W LED Downlight Surface Mounted - Black

The Astim is a surface-mounted LED downlight in a slim rectangular format, measuring 400 by 100mm and drawing 8W to deliver 590 lumens at a neutral 4000K white. American buyers shopping for a recessed can light should note the difference here: rather than dropping into a hole, this fitting sits flush against the surface it is fixed to, giving a low-profile linear wash rather than a single round spot. The wide asymmetric beam of 120 degrees by 105 degrees spreads light evenly across the area below, and the integrated LED runs at 74 lm/W with a rated life of 25,000 hours.

At 590 lumens this fitting covers around 2 m² at general lighting levels, which makes it well suited to smaller zones rather than whole-room ambient lighting. Think bathroom ceilings, shower areas, hallways and entrance porches, where its elongated shape works neatly over a basin, mirror or doorway. The IP44 rating means it copes with splashes and sheltered damp conditions, so it is at home in bathroom zones and covered outdoor spots such as a porch or carport. Keep it clear of fully-exposed positions, direct water jets and any submerged use, as the rating does not extend that far.

The body is aluminium alloy in a black finish, giving a sturdy housing that suits a contemporary scheme. It runs from a 220 to 240V AC mains supply and is surface mounted, fixing directly onto the ceiling or wall without the need for a recessed cut-out, which suits solid ceilings where recessing is not practical. The 4000K colour temperature is fixed and the fitting is not dimmable, so it gives a steady neutral output throughout its life. The Astim range includes further sizes and wattages if you need to match fittings across several rooms.

Does this downlight need a cut-out hole?

No, the Astim is surface mounted rather than recessed, so it fixes directly onto the ceiling or wall and needs no cut-out. This makes it a practical choice for solid or concrete ceilings where recessing is not possible. You only need a fixing point and access to the mains supply behind it.

Can it be used in a bathroom?

Yes, the IP44 rating means it is splash-resistant and suitable for bathroom zones away from direct water contact, as well as sheltered outdoor spots like a porch. It should not be fitted where it would face direct water jets or full exposure to the weather. For a typical bathroom ceiling or shower-area position it is well suited.

What colour temperature does it give and is it adjustable?

It produces a fixed 4000K neutral white, a clean daylight-leaning tone that works well in bathrooms and hallways. The colour temperature is not selectable on this model, so the output stays consistent. If you prefer a warmer or cooler tone, check the other fittings in the Astim range.

How should I clean it?

Wipe the fitting with a soft, dry or slightly damp cloth, switching off the power first and letting it cool. Avoid abrasive pads or solvent cleaners, as these can mark the black aluminium finish. A gentle wipe every few weeks keeps the surface looking its best and maintains light output.
