Notus 620x620 4x18W Square T8 LED Ceiling Light 3WS - White

The Notus is a square LED ceiling light built around four 18W G13 T8 lamps running on a 220-240V AC supply. Often described in US terms as a surface-mounted troffer-style fixture, it sits directly against the ceiling rather than dropping into a grid, with the four T8 tubes spreading light evenly across the 615 x 615 mm white steel frame. The 3WS lamp arrangement gives a broad, low-shadow wash that suits rooms where flat, all-over brightness matters more than directional accent.

This fitting works best in offices, workshops, utility rooms, store rooms and reception areas where a steady working light is wanted across the whole space. Its 615 x 615 mm footprint reads as a tidy square panel on the ceiling, so it pairs well over a single workstation or in the centre of a small to mid-sized room. Across a wider floor area the four-lamp output gives generous coverage for general tasks, with enough light to read, sort and work by. It is an indoor fitting only, so keep it to dry rooms and clear of bathrooms, porches and any sheltered-outdoor positions.

The body is steel finished in white, giving a clean square shape that suits modern interiors and recesses visually into a plain ceiling. Rated IP20, it is designed for dry indoor use, and the four T8 tubes seat into standard G13 caps so lamps can be replaced individually over time. It mounts flush to the ceiling and weighs 2.42 kg, so a secure fixing into the ceiling structure is needed. The Notus range also runs to other sizes and lamp counts, so a matching look can be carried across several rooms.

What room size does it suit?

The Notus uses four 18W T8 lamps, giving a broad, even spread that works well in small to mid-sized offices, workshops and utility rooms. Its square 615 x 615 mm format suits a single workstation or the centre of a compact room. For larger floors, several units can be spaced out to keep light levels consistent.

Can I replace the lamps?

Yes. Unlike an integrated LED fitting, the Notus takes four standard T8 tubes seated into G13 caps, so individual lamps can be swapped out as needed rather than replacing the whole fixture. This makes long-term maintenance straightforward.

Is it suitable for outdoor or bathroom use?

No. The Notus is rated IP20, which means it is for dry indoor use only. Keep it out of bathrooms, porches, carports and any damp or sheltered-outdoor location, and install it in offices, utility rooms or similar dry interiors instead.

How do I clean it?

Switch off and allow the lamps to cool, then wipe the white steel frame and the lamp covers with a soft, dry or barely damp cloth. Avoid abrasive cleaners or solvents that could mark the finish. Regular dusting keeps light output at its best in working spaces.
