This listing sells the 7W Nella Tilt in both finishes HV5812T-WHT in white and HV5812T-BLK in black. It is the smallest fitting in the Nella surface-mounted family at 75mm across the face by 102mm deep, it needs no ceiling cut-out, and the lamp module inside it swings 20 so the light can be aimed after the fitting is on the ceiling.

What 20 of tilt is actually for

Twenty degrees is a modest, deliberate amount of movement. It is enough to lift a beam off the floor and onto a wall, a splashback or a run of joinery from a fitting set back a little way from it, and it is not enough to aim across a room. The beam itself is 60, so the tilt is steering a reasonably contained cone rather than nudging a broad wash which is the practical difference between this model and the 18W HV5805T, whose 120 beam is fixed and points straight down. Havit prints tilt and beam angle in adjacent columns on its sheet, where they are easily read as one figure, so they are stated separately here.

IP40 the specification most likely to be assumed wrong

This fitting is IP40. Three of the five Nella surface mounts are IP54 and this one is not, and nothing in the range name or the part number tells you which you are buying. IP40 means it resists solid objects down to 1mm and carries no water rating at all. It is an interior fitting: a bedroom, a hallway, a retail display, a stair soffit. It is not a shower zone, not an eave, not an unlined carport, and not a bathroom position that could take splashing. If the location can get wet, the IP54 members of the family are the fittings to look at instead.

Output and colour temperature

A slide switch inside the fitting selects 3000K, 4000K or 5500K before it goes up. Havit’s ordering row measures 600lm at 3000K, 640lm at 4000K and 605lm at 5500K for every part number on this listing. The brightest setting is 4000K; the warm and cool ends are within five lumens of each other, so at either extreme the choice is purely about how the room should feel. Seven watts delivering 640lm is a genuinely small fitting sensible in a tight ceiling grid or a low ceiling where a larger head would dominate, and not a substitute for one of the higher-wattage models in a large room.

Mounting and electrical

A 72mm mounting base is fixed to the ceiling and the 75mm body covers it, so the fitting conceals its own fixings with very little margin mark out carefully. It runs on 240V AC, is Protection Class 1 so an earth is required at the fitting, and is Triac dimmable from a standard wall dimmer, with Havit’s HV9625 dimmer offered to suit.

Materials, siting and warranty

Powder-coated aluminium behind a Semi Frosted Glass diffuser, IK07, CRI>80, lamp expectancy >30,000hrs. Its own installation sheet states a condition on the fitting: “Aluminium and 304SS fittings must not be installed within 5km of any salt water environments.” Havit’s page for these part numbers reads “Built-in 7w LED 3 Years replacement warranty (items ordered after 01/01/22)”, and HV5812T_Data_Sheet_JULY23.pdf prints “Warranty 3 Years Replacement*”. Lights For You publishes here only what this model’s own dated sheet and Havit’s page for these exact part numbers state.

Questions

Is this suitable for a bathroom?

It is IP40, which carries no water rating, so it is not a fitting for a shower zone or any position that can be splashed. Three of the five Nella surface mounts are IP54 and this one is not check the rating rather than the range name.

How far does it tilt, and how wide is the beam?

The module tilts 20 and the beam is 60. They are two different numbers printed in adjacent columns on Havits sheet. The tilt aims the beam; it does not widen it.

Does it need a cut-out?

No. A 72mm base is screwed to the ceiling and the 75mm body covers it. Nothing is cut and no plenum depth is needed.

Which setting is brightest?

4000K, at 640lm. 3000K gives 600lm and 5500K gives 605lm five lumens apart, so the warm and cool ends are effectively identical in output.

How big is it?

75mm across the face by 102mm deep, on a 72mm base. It is the smallest fitting in the Nella surface-mounted family.

Can I dim it, and does it need an earth?

Yes to both: it is Triac dimmable from a standard wall dimmer (Havit lists the HV9625 to suit) and it is Protection Class 1, so an earth is required at the fitting.

Is 7 W enough?

It delivers up to 640lm, which suits a hallway, a bedside position, a stair soffit or a retail display where a larger head would dominate. For general light in a living area, the 12 W and 18 W members of the family are the fittings to compare.
