Nella LED Downlight 7w Black, White CCT HV5841S-EXT Havit Lighting

This is the extended-body version of the Nella 7 W surface mounted downlight. The light engine is identical to the standard model — same 7 W built-in LED, same five colour settings, same output — but the housing is 200 mm tall instead of 100 mm, so the fitting projects twice as far below the ceiling.

That extra length is a design decision rather than a technical one, and it is the only thing separating this product from its shorter sibling. A longer barrel reads as a deliberate architectural cylinder rather than a low puck, and it drops the light source further into the room — useful over an island bench, in a stairwell, or on a high ceiling where a flush fitting disappears into the plane above. If you want the same light with the smallest possible protrusion, the 100 mm standard Nella is the one to order.

Light quality

Havit's data sheet puts this fitting at CRI >90 with SDCM <3 colour consistency and UGR <10 for glare. The deep baffled aperture is doing the work on that last figure — the LED sits well back from the opening, which matters more, not less, on an extended body where the fitting hangs in view.

Output follows the colour setting: 499 lm at 2700K, 512 lm at 3000K, 558 lm at 4000K, 593 lm at 5000K and 601 lm at 5700K, through a 60° beam. The five settings are selected on the fitting during installation, so one product code covers every room in a job.

Installation

This listing is the 240 V AC model: no driver in the circuit, wired directly to mains, Protection Class I with an earth connection required, and wired in parallel across multiple fittings. Dimming is Triac, matched to Havit's HV9625 dimmer. Because it is surface mounted, there is no cutout to make and no ceiling cavity depth to check — only the fixing surface itself.

IP54 covers dust and splashing water from any direction, and the aluminium body is rated IK08 for impact with a lamp expectancy over 30,000 hours. Gold, black and chrome trim inserts fit the same aperture if you want to change the look later.

The fitting carries Havit's 3 year replacement warranty. Lights For You keeps the standard and extended Nella bodies side by side precisely because the specification sheets do not distinguish them on anything but height — so you can choose on proportion, and know the light itself is the same.
