Prime Coloured Fixed Deep Downlight 90mm Cutout

This listing sells the fixed deep Prime downlight on a Ø90 mm cut-out in all six of Havit's finishes — antique brass, brass, copper and nickel alongside white and black. Each is a complete 12 W 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 Ø90 mm cut-out: this fixed deep body and the tilting HV5512. That is worth knowing before you buy, because it means an existing 90 mm 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 Ø70 mm and Ø76 mm holes and will not fit, and nothing in the range name or the finish distinguishes them. The face measures Ø105 mm, so it covers a rough or previously enlarged 90 mm 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 839 lm, 913 lm and 841 lm 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 12 W 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 240 V 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 >50,000 hrs. 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.
