This listing sells the fixed deep Prime downlight on a 90mm cut-out in all six of Havit’s finishes antique brass, brass, copper and nickel alongside white and black. Each is a complete 12W luminaire with its driver, flex and plug. It is the largest hole in the range and the deep housing behind it is what the model is for.

The 90 mm hole, and what else fits it

Two Prime models take a 90mm cut-out: this fixed deep body and the tilting HV5512. That is worth knowing before you buy, because it means an existing 90mm ceiling can take either the low-glare fixed one here, or a tilting one where light needs aiming at a wall. The other two Prime bodies take 70mm and 76mm holes and will not fit, and nothing in the range name or the finish distinguishes them. The face measures 105mm, so it covers a rough or previously enlarged 90mm hole with a reasonable margin.

What the deep body changes

The light source is set well back from the face, so what you see from across a room is the lit surface rather than the emitter. Havit publishes that as UGR<19 for this model against <22 on the shallow HV5511 and HV5512 housings a real difference in discomfort glare, and the reason to choose a deep body for a lounge, a bedroom or any room people sit and look up in. What it costs is ceiling depth.

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 points, so 4000K is brightest by about 9% and the warm and cool ends are two lumens apart the colour decision costs nothing in light. Those figures are identical across all four Prime bodies from the same 12W engine; the housing changes the hole and the glare rating, not the output. The beam is 60, with CRI>90 and SDCM<4.

Dimming and insulation

The supplied driver is Triac dimmable, so an ordinary wall dimmer works; Havit offers the HV9625 to suit its Triac dimmable drivers. It is IC-4 rated, and the rating comes 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, on 240V AC, Protection Class 2 so no earth is required at the fitting, and IP54 at the front of the fitting only an indoor recessed downlight. 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 available should be checked on site rather than taken from an unattributed number.

Questions

What cut-out does it need?

90mm, with a face of 105mm. The tilting HV5512 takes the same hole, so an existing 90mm ceiling can take either model; the other two Prime bodies use 70mm and 76mm and will not fit.

Why is no depth shown?

Havit does not label it. The dimension drawing on this models data sheet and on the installation sheet carries two figures with nothing identifying which is the overall depth, and Havits website publishes no dimensions in its page copy. The cut-out and the face diameter are published because every source agrees on them.

How is this different from the tilting HV5512?

Same hole, different job. This one is fixed and sits deeper, which is what gives it the UGR <19 glare rating; the HV5512 tilts 20 so it can aim light at a wall, and is rated <22. Choose on whether the light needs aiming or needs to disappear.

Which colour temperature is brightest?

4000K, at 913lm. 3000K gives 839lm and 5500K gives 841lm two lumens between the two ends so pick the colour for the room, not for the output.

Is it dimmable?

Yes. The supplied driver is Triac dimmable so a standard wall dimmer works, and Havit offers the HV9625 to suit its Triac dimmable drivers. The Wi-Fi RGBCW version of this body is dimmed in an app instead and is 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 the brass and copper finishes solid metal?

No the body is aluminium and those names describe the finish applied to it. Havits data sheet gives the material as aluminium for every one of the six finishes on this listing.
