This is the original Nella 12W surface mounted downlight the tri-colour, glass-diffused body that preceded Havit’s five-colour models. It is a different fitting from the five-colour Nella despite the shared name, and the differences are worth understanding before you mix them on one ceiling.

Where the newer bodies use a deep baffle and a narrow 60 beam, this one runs a 120 beam through an aluminium-and-glass housing. That is a genuinely wide spread: it washes a room evenly from fewer fittings rather than dropping defined pools of light, which suits hallways, bedrooms and general living areas more than it suits task lighting over a bench.

Tri-colour output

Three colour settings are built in and selected at installation: 995lm at 3000K, 1,125lm at 4000K and 1,050lm at 5500K. Note the shape of that: the brightest setting is 4000K in the middle, not 5500K at the top. It is natural to assume a cooler LED is a brighter one, and on this fitting the opposite holds above 4000K so if you want the most light on the floor, 4000K is the setting, and 5500K is a colour choice you pay about 75lm for. Colour rendering is CRI>80.

Both black and white finishes are available from this listing, and both carry identical output; the finish is a styling decision rather than a performance one.

Glass, not plastic

One detail separates this generation from the newer five-colour Nella bodies and it is worth knowing: Havit’s specification for this fitting lists the material as aluminium with a glass diffuser, where the five-colour models use a plastic diffuser. Glass holds its clarity over time rather than yellowing under heat, and it wipes clean without scratching a real advantage in a kitchen or a bathroom where the fitting will be washed rather than dusted. The trade-off is toughness: glass is more brittle than the plastic used on the five-colour bodies, which Havit rates IK08 for impact. This is not the fitting for a garage, a workshop, or a ceiling within reach of a swung object.

Installation

Being surface mounted, the Nella needs no cutout it fixes to a mounting base flat against the ceiling, which makes it usable on concrete, render and timber linings where a recessed fitting cannot go. It runs on 240V AC wired directly to mains with no driver in the circuit, and multiple fittings are wired in parallel.

The fitting is IP54 rated dust protected and sealed against splashing water from any direction which covers bathroom ceilings and covered outdoor areas, though not immersion or high-pressure water. Dimming is Triac.

Havit’s warranty on this fitting is 3 years replacement. Some older printed documentation for this model still shows a shorter term; the current entitlement is 3 years and that is what Lights For You honours on every Nella sold.

Lights For You stocks both the tri-colour and the five-colour Nella bodies, and it is worth checking which one an existing ceiling uses before ordering replacements the beam angles are 120 and 60 respectively, and mixing them in one room is visible.

Coastal siting Havits condition

Havits installation instructions for this fitting state that aluminium and 304 stainless steel fittings must not be installed within 5 km of any salt water environment. That is a condition on where the fitting may go, and it sits beside the IP rating rather than inside it: a fitting can be rated for direct rain and still fall outside this rule, because the issue is salt carried in the air rather than water landing on the surface. If your site is inside that zone, talk to us before you specify it Lights For You can point you at a fitting whose material Havit does not name here.

Earthing and protection class

This fitting runs on 240 V AC mains and is Protection Class 1 an earth is required at the fitting. Havit’s installation sheet has the installer connect the earth conductor first, then live and neutral.

Questions

How is this different from the five-colour Nella?

Two things matter. This is a tri-colour fitting (3000K, 4000K, 5500K) rather than five-colour, and it runs a 120 beam through a glass diffuser rather than a 60 beam through a deep baffle. The wide beam washes a room evenly; the narrow one places defined pools of light. Mixing the two in a single room is noticeable.

What is the light output?

995lm at 3000K, 1,125lm at 4000K and 1,050lm at 5500K. The middle setting is the brightest output does not keep climbing as the light gets cooler. The setting is chosen on the fitting during installation, so one product code covers all three.

Do I need to cut a hole in the ceiling?

No. It is surface mounted and fixes to a mounting base against the ceiling, so there is no cutout to make and no clearance required in the ceiling cavity.

Does it need a driver or transformer?

No. It runs on 240V AC wired directly to mains, with fittings wired in parallel across a run. Installation is work for a licensed electrician.

How long is the warranty?

Three years replacement. Some older printed material for this model still shows a shorter term, but the current Havit entitlement is 3 years and that is what applies to this product.

Can it be dimmed?

Yes it is Triac dimmable. Use a dimmer rated for LED loads and check the dimmer’s minimum load against the number of fittings you are putting on the circuit.

Can I use it in a bathroom?

IP54 gives dust protection and resistance to splashing water from any direction, which suits bathroom ceilings and covered outdoor areas. It is not rated for immersion or direct high-pressure water, so confirm the zone with your electrician.
