Nella White 18w Surface Mounted LED Downlight

This is the 18 W Nella in the extension body — the largest output in the tri-colour surface mounted family, in a housing that stands well clear of the ceiling. It is the fitting to specify when a room needs real light from a surface mount and you want the fitting to read as a deliberate cylinder rather than disappear into the plane above.

Both white and black finishes are covered by this listing, and both perform identically; the finish is a styling decision.

Semi-frosted glass, not plastic

Havit specifies this body with a semi frosted glass diffuser, which is the detail that separates this generation from the five-colour Nella range running plastic. Glass holds its clarity instead of yellowing under sustained heat and wipes clean without scratching — worth having in a kitchen or bathroom where the fitting gets washed rather than dusted. The trade-off is impact resistance: this body is rated IK07 against IK08 for the plastic-diffused models, so it is the softer choice for a garage or workshop ceiling.

Output, and which setting is brightest

Three colour settings are built in and chosen at installation, and the brightest is not the coolest: 1,380 lm at 3000K, 1,430 lm at 4000K and 1,305 lm at 5500K. Output peaks at 4000K and falls away above it, so if you want the most light on the floor, 4000K is the setting — and 5500K costs you around 125 lm for the cooler colour. Colour rendering is CRI >80.

Installation

No cutout is required. The fitting attaches to a mounting base against the ceiling surface, so it works on concrete, render and timber linings, and in renovations where the ceiling cavity cannot be reached. Allow for the depth of the extension housing when you check clearance in circulation areas.

It runs on 240 V AC wired directly to mains with no driver in the circuit. It is Protection Class I, so an earth connection is required, and fittings are wired in parallel across a run. Dimming is Triac, and Havit lists the HV9625 Triac Dimmer as the matching control. The IP54 rating covers dust and splashing water from any direction — bathroom ceilings and under-cover outdoor areas — but not immersion or high-pressure water.

Lamp expectancy is over 30,000 hours and the warranty is 3 years replacement. Lights For You lists the 7 W, 12 W and 18 W extension bodies together so the step up in output can be weighed against the extra size before a ceiling is committed to one of them.
