This listing is the Prime recessed downlight in the two standard finishes HV5511T-BLK matt black and HV5511T-WHT white on a 70mm cut-out. Both are the same 12W aluminium fitting supplied complete with a Triac dimmable driver, flex and plug, and both sit below the metallic finishes of the same model in price while giving identical light.

Why this is the volume choice

Black and white are the finishes that disappear: white against a painted ceiling, black against a dark or raked one, and black is also the finish that reads as least visible when the light is off because the aperture and the trim are the same tone. If a whole house is being fitted out, this is the part number that does it, with the brass, copper, nickel and antique brass versions of the identical fitting reserved for the rooms where the trim is meant to be seen.

What the specification is buying

The Prime renders at CRI>90 high enough that timber, paint and skin tones keep their depth and is binned to SDCM<4, so a run of them across one ceiling reads as a single installation rather than as slightly different whites. Glare is held to UGR<22 behind a clear glass lens, the body is IK06, and lamp expectancy is >50,000hrs.

Output and colour

A switch selects 3000K, 4000K or 5500K, and Havit measures 839lm, 913lm and 841lm in that order. 4000K is the brightest by about 9%, and 3000K and 5500K are within two lumens of each other so the warm-versus-cool decision on this fitting costs nothing in output. The beam is 60, and the head is fixed with no tilt.

IC-4, insulation and warranty

The Prime is IC-4 rated without an accessory, but the rating covers the fitting rather than the whole assembly: the driver must be mounted above any insulation covering the fixture so it can ventilate, and loose-fill insulation such as macerated paper or wool must not be used with this fixture. It runs on 240V AC, is Protection Class 2 so no earth is required at the fitting, and dims over 10100% on a Triac dimmer such as Havit’s HV9625. IP54 applies to the front of the fitting only. Havit’s warranty line for these part numbers reads “3 Years replacement warranty (items ordered after 01/01/22)”. An older undated sheet attached to this listing shows a shorter term; the current dated model data sheet, the stored warranty value and Havit’s own page all give the three-year figure, and Lights For You publishes that.

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.

Questions

What cut-out does it need?

70mm, with a body of 88mm across the face by 70mm deep. Two of the other Prime models use 76mm and 90mm cut-outs, so check the part number against the hole rather than the range name.

Is the black one different from the white one in any way?

Only in finish. Both are HV5511T on the same ordering row of the same data sheet, with identical output, beam, cut-out, ratings and warranty.

Which colour temperature is brightest?

4000K, at 913lm. 3000K gives 839lm and 5500K gives 841lm two lumens apart, so choosing between warm and cool costs no light.

Can it be covered by insulation?

The fitting is IC-4 rated and may be. The driver may not Havit requires that the driver must be mounted above any insulation covering the fixture so that it can ventilate, and that loose-fill insulation such as macerated paper or wool is not used with this fixture at all.

Does it need an earth?

No. It is Protection Class 2 and is supplied with a flex and plug that lands on a plug base installed in the ceiling.

How far does it dim?

Havit publishes a dimming range of 10100% using a Triac dimmer, with the HV9625 offered to suit its Triac dimmable drivers.

One of the attached sheets shows a shorter warranty which applies?

The three-year term. The shorter figure comes from an older undated sheet; the current dated model data sheet, this products stored warranty value and Havits own page for both part numbers all state three years replacement.
