The longest fitting of the four brass listings: the 12W extension body, 90mm across and 240mm deep. It is the one to specify when a surface-mounted downlight has to hold its own against a high ceiling and a large room, and when the brass finish is meant to be seen rather than tolerated.

Length, not light

The extension doubles the housing and leaves the optics alone same 12W engine, same 60 beam, same 688 / 840 / 916 / 931 / 1,004lm as the 120mm body. There are two real reasons to pay for the extra length. The first is proportion: at 240mm the fitting is an object in the room, and on a 3m-plus ceiling a short body simply reads as a smudge. The second is clearance the extension drops the source below a deep bulkhead, service run or cornice that would otherwise shade the edge of the beam.

Indoors only, per Havit

The colour row on Havit’s own data sheet carries a footnote: “Brass Model can only be used indoors”. The black and white versions of exactly this body are rated for covered outdoor use; the brass one is excluded, and the IP54 rating does not override it. Specify this for interiors stairwells, double-height living rooms, hospitality and use a black or white body where the ceiling is outside.

Colour, glare and rendering

Five settings from 2700K to 5700K, selected on a switch inside the body, and on this wattage the difference is substantial: the warmest setting delivers about a third less light than the coolest. Decide the colour before you decide the quantity. Glare is rated UGR<10 thanks to the honeycomb baffle behind the lens, colour rendering is CRI>90, and SDCM<3 binning keeps a row of them consistent with each other.

Supply and earthing

Both versions are on this page. The 240V model is Protection Class 1 and requires an earth, connected before positive and neutral, and it is the Triac dimmable one. The 12V DC model runs from a constant-voltage driver, wires in parallel, is Protection Class 3 with no earth at the fitting, and is not dimmable per Havit.

Installation and warranty

The 85mm base plate, 34mm deep, screws to the ceiling through two 9 4mm slots and the body twists on no cut-out, only a cable hole. Set the colour switch before the body goes home; it is preset to 3000K. Rated IP54, IK08 and >30,000hrs, with Havit’s aluminium exclusion for sites within 5km of salt water. Warranty is 3 years replacement. Lights For You lists the 7W extension at 200mm for the same look at lower output, which is how most mixed schemes in this range are put together.

Questions

How long is this one?

240mm, on a 90mm body the longest of the four brass listings. The standard 12W body is 120mm, and the 7W extension is 200mm on a 75mm body.

Is it brighter than the shorter version?

No. Both are 12W and give 688 / 840 / 916 / 931 / 1,004lm with a 60 beam. The extension changes the length of the housing only.

Can it go on a covered outdoor ceiling?

No. Havit restricts the brass model to indoor use in a footnote on its data sheet, whatever the IP54 rating suggests. Use the black or white version of the same body outdoors under cover.

How much light does the warm setting cost?

About a third. 2700K gives 688lm against 1,004lm at 5700K, so on this wattage the colour choice is also a brightness choice much more so than on the 7W body.

Which one dims?

The 240V model, on a Triac dimmer. The 12V DC model is specified as not dimmable, so dimming would depend on a driver built for it.

Is an earth required?

On the 240V model yes Protection Class 1. The 12V DC model is Class 3 and lands no earth at the fitting.

Is the brass finish solid metal?

No a brass-coloured powder coat over aluminium. Havit lists the material as aluminium, which is why the 5km salt-water exclusion applies to it.
