A suggestion, not a specification. A calculator can get it wrong — have a licensed electrician confirm the driver, the total load and the wiring before you order.
A surface mounted round downlight, Ø75mm, rated IP65 and IK08. Surface mounted rather than recessed is the whole point of this fitting: it fixes to the underside of a ceiling, a soffit or a beam without a cutout, which is what makes it usable where recessing is impossible — concrete slabs, timber-lined ceilings, eaves with no cavity, and rented or heritage spaces where cutting the ceiling is not on the table.
The IP65 rating means it works outside as well as in. Under an eave, in a carport, over an alfresco area or in a bathroom, the same fitting applies.
In white with the extended mounting base, this is the version most often specified for plasterboard ceilings and painted soffits, where the fitting is meant to disappear into the surface rather than sit on it as a dark disc.
This is a five-step CCT fitting rather than the usual three: 2700K, 3000K, 4000K, 5000K and 5700K, selected on the fitting at installation. Output rises across the range — 560lm, 570lm, 580lm, 590lm and 600lm respectively — from a 7W draw.
Five steps is genuinely useful when a fitting has to work across different rooms in one job. 2700K suits a bedroom or a warm timber ceiling; 4000K is the neutral choice for a kitchen or bathroom; 5700K suits a garage or a workshop. One part number covers all of them.
The Nella is rated above 90 CRI, which is well above what a typical domestic downlight offers. On a ceiling that difference shows on skin tones, timber, paint colours and food — the reason to specify it in a kitchen, a bathroom or anywhere people are seen under it.
The fitting is made in both 240V mains and 12V DC low-voltage versions, and this listing carries one of each. ⚠ The 240V versions are Class 1 and require an earth; the 12V versions are Class 3, need no earth at the fitting, and do require a 12V DC driver on the circuit that is not supplied.
⚠ Havit states the fitting is Triac dimmable on the 240V models only. If dimming is part of the plan, that decides which version to order — a 12V Nella on a dimmed circuit will not behave as expected.
No cutout is needed, but the mounting base does need a fixing point and a cable entry, so the ceiling still has to be prepared. Rated lamp expectancy is >30,000 hrs and the LED is built in, so there is no globe to buy or replace.
Havit states that aluminium and 304 stainless fittings must not be installed within 5km of any salt water environment. Installation is work for a licensed electrician.
No. It is surface mounted, so it fixes to the ceiling face without cutting a hole.
Only the 240V models, which are Triac dimmable. The 12V models are not.
Yes. It is rated IP65 for dust and jetted water, and IK08 for impact.
Five — 2700K, 3000K, 4000K, 5000K and 5700K — selected at installation.
Yes, a 12V DC driver, and it is not supplied with the fitting.
