40W LED Recessed Downlight | High Ceiling Light with Selectable CCT

The top of the range

40W is as much output as a single recessed fixture sensibly delivers. Past this point you are into high bay territory, where the fixture hangs below the ceiling rather than sitting inside it. This is the last size that still disappears into a ceiling.

Specify it where the ceiling is high enough that light has a long way to travel, or where the floor area is large enough that fewer, brighter fixtures beat a grid of small ones.

Specification

Is 40W right, or is it too much

At a normal ceiling height a 40W fixture is uncomfortable to stand under and wastes most of its output. Height is what justifies it, not floor area on its own.

Circuit load

Ten of these is 400W on one circuit before anything else is connected. On a project of any size, the electrician needs the full fixture count before the first cable goes in. Working it out halfway through means rerunning circuits.

Where it belongs

• Warehouses and distribution floors with open ceilings.
• Sports halls and gyms where the roof is well above head height.
• Atriums and double-height lobbies.
• Large retail floors where light must reach the floor from a long way up.
• Workshops with high roofs and machinery below.

Colour temperature

Selectable at the fixture. Cooler settings suit a warehouse or a workshop where seeing detail matters. Neutral suits retail and lobbies. Keep the whole space on one setting.

Installation

Hardwired and recessed, fitted by a licensed electrician. Confirm void depth, insulation clearance and total circuit load before any cutting.
