This listing sells the fixed deep Prime downlight on a 76mm cut-out in all six of Havit’s finishes antique brass, brass, copper and nickel alongside black and white. Each is a complete 12W luminaire with its driver, flex and plug. It does not tilt, and the depth of the housing is the point of it.

What “deep” buys you

The light source sits further back behind the face than on the shallow Prime bodies, so you see the lit surface rather than the emitter when you look up at it from across a room. Havit publishes the result of that as a UGR of <19 for this model, against <22 on the shallow HV5511 and HV5512 housings a measurable difference in discomfort glare, and the reason to choose a deep body for a room people sit and look up in. It costs ceiling depth, which is the trade to weigh against it.

The smallest hole in the deep range

76mm is the only cut-out this model takes. The deep body is also made for a 90mm hole as the HV5514, so if you are replacing existing downlights the part number rather than the range name is what has to match the ceiling. Across the whole Prime range the holes are 70mm, 76mm and 90mm, and nothing in the finish or the title distinguishes them.

Colour temperature and output

A slide switch on the back sets 3000K, 4000K or 5500K before installation. Havit measures 839lm, 913lm and 841lm at those three points, so 4000K is the brightest by roughly 9% and the warm and cool ends differ by two lumens. Those are the same figures the other three Prime bodies produce from the same 12W engine the housings change the hole and the glare, not the light. The beam is 60 and colour rendering is CRI>90 with SDCM<4, which is a tight enough binning that adjacent fittings should not read as different whites.

Dimming and insulation

The supplied driver is Triac dimmable, so an ordinary wall dimmer works and Havit offers the HV9625 to suit its Triac dimmable drivers. It is IC-4 rated with conditions: only the LED fitting may sit under insulation, the driver must never be covered and must be mounted above any insulation covering the fixture, and the fixture must not be used with loose-fill insulation such as macerated paper or wool.

Body, rating and warranty

The body is aluminium with a clear glass diffuser and measures 84mm across the face. It runs on 240V AC, is Protection Class 2 so no earth is required at the fitting, and is IP54 at the front of the fitting only. IK06, lamp expectancy >50,000hrs. Havit’s warranty line for these part numbers reads “3 Years replacement warranty (items ordered after 01/01/22)”. Lights For You does not publish an overall depth for this model: Havit’s drawing carries two unlabelled figures and does not say which is the depth of the housing, so the recess required should be confirmed on site rather than taken from a number nobody has attributed.

Questions

What cut-out does it need?

76mm, with a face of 84mm. The Prime range uses 70mm, 76mm and 90mm cut-outs across its four bodies, so match the part number to the hole rather than the range name.

Why is no depth shown?

Because Havit does not label it. The dimension drawing on this models data sheet and on the installation sheet carries two figures with nothing saying which is the overall depth, and Havits website publishes no dimensions in its page copy. Rather than pick one, this page publishes the face diameter and the cut-out, both of which every source agrees on.

What does the deep body actually change?

Glare. The emitter sits further back, and Havit rates this model UGR <19 against <22 on the shallow HV5511 and HV5512 bodies. It matters most in rooms where people look up a lounge, a bedroom, a long hallway.

Which colour temperature is brightest?

4000K, at 913lm. 3000K gives 839lm and 5500K gives 841lm, so the two ends are two lumens apart and the choice is about the room rather than about brightness.

Is it dimmable?

Yes the supplied driver is Triac dimmable, so a standard wall dimmer works, and Havit offers the HV9625 dimmer to suit its Triac dimmable drivers. The Wi-Fi versions of this body are dimmed in an app instead and are not intended for a dimmer plate.

Can it be covered by insulation?

It is IC-4 rated, with conditions. Only the LED fitting may be under insulation; the driver must never be covered and must be mounted above any insulation covering the fixture. Loose-fill insulation such as macerated paper or wool must not be used with this fixture at all.

Are all six finishes the same fitting?

Yes. One aluminium body, one light engine, one 76mm cut-out; the antique brass, brass, copper and nickel names describe the finish rather than the metal, and black and white are the same housing powder coated.
