This listing sells the 76mm deep Prime RGBCW in both plain finishes HV5513RGBCW-BLK and HV5513RGBCW-WHT. It is a 12W recessed downlight with a wifi radio in it: the white light tunes, the colour channels change, and everything is set from the Tuya app rather than from a switch on the wall.

The one fact that decides whether this is the right fitting

An RGBCW Prime is much dimmer than the switched or tunable-white Prime of the same size and the same 12W. Havit measures this model at 300lm at 3000K and 320lm at 5500K, against 839913lm for the tri-colour HV5513T in the identical 76mm body. That is roughly a third of the light for the same wattage and a similar price, and the red, green and blue channels are dimmer again colour light is a fraction of white light on any RGB fitting, and the figures on Havit’s sheet make that explicit. Specify this where the colour is the point a media room, a bar, a display niche, a child’s room and specify the tri-colour or CCT Prime where the room has to be lit.

Control

Dimming and colour are handled in the Tuya app, not at the wall. There is no Triac dimmer behind this fitting and it should not be put on one. The white channel tunes across 3000K to 5500K on this model’s own dated data sheet. Havit’s page copy for the same part numbers describes the cool point as 6500K instead, and the two are not reconciled anywhere in its material, so the sheet’s pairing is what is published here and the disagreement is stated rather than hidden.

The hole, and the depth behind it

The cut-out is 76mm and the face measures 84mm, so there is about 4mm of trim all round to cover the edge of the hole. This is a deep body that is what the shallow and deep halves of the Prime range differ by, and it is why this model is rated UGR<19 where the shallow 90mm Prime is <22: the source sits further back from the aperture. Havit's drawing carries two unlabelled figures for the body, so no overall depth is published here; measure the plenum before committing to a deep body in a shallow ceiling.

Insulation, and what IC-4 does and does not permit

The fitting is IC-4 rated, so insulation may abut and cover it. The driver is a separate question: Havit’s installation sheet requires the driver to be mounted above any insulation covering the fixture and never covered by it, and forbids loose-fill insulation over the installation. The two conditions travel together and only the first one is what “IC-4” names.

Electrical, rating and warranty

It runs on 240V AC and is Protection Class 2, so no earth is required at the fitting, and it is supplied with a flex and plug. The face is rated IP54, front of the fitting only the aperture resists splashing, the body above the ceiling does not, so this is a covered interior fitting and not an exterior one. The body is aluminium behind a frosted perspex diffuser, IK06, with colour rendering CRI>90 and colour consistency SDCM<4, on a 120 beam. Warranty is 3 years replacement. Lights For You publishes here only what this model’s own data sheet states against these two part numbers and their barcodes.

Questions

Is it as bright as the normal Prime downlight?

No, and this is the main thing to know. Havit measures it at 300lm at 3000K and 320lm at 5500K, against 839913lm for the tri-colour HV5513T in the same 76mm body roughly a third of the light for the same 12W. Buy it for the colour, not for the light.

How is it controlled?

Through the Tuya app over wifi brightness, white colour temperature and RGB colour. It is not dimmed from a wall dimmer and must not be put on a Triac dimmer.

What size hole does it need?

76mm. The visible face is 84mm, so about 4mm of trim covers the edge of the cut.

Can it be covered with insulation?

The fitting is IC-4 rated, so insulation may cover it. The driver may not Havit requires the driver to sit above any insulation and never be covered, and no loose-fill insulation may be used over the installation.

Does it need an earth?

No. It is Protection Class 2, double insulated, and is supplied with a flex and plug. It is still a licensed electricians installation.

Can I use it in a bathroom or outside?

It is IP54 at the front of the fitting only, which means the visible face resists splashing while the body above the ceiling is not rated. It is an interior fitting for a covered ceiling.

What is the difference between this and the 90mm RGBCW?

The hole, and the glare figure. This one cuts 76mm; the other cuts 90mm. Both are deep bodies with the same 12W engine and the same output.
