This is the two-head Focus with a microwave occupancy sensor built into the base the same 15W head as the single-head model, doubled, on a fitting that switches itself. It suits the places where a light is genuinely useful only when someone is there: a side path, a carport, a back door, a set of external stairs.

What the sensor actually does

Havit specifies a microwave sensor at 5.8GHz with a detection field of 180 and a range of up to 12m. Microwave sensing differs from the passive infrared used in cheaper fittings: it detects movement rather than body heat, so it still triggers reliably on a cold night when a persons thermal signature is close to the background, and it can see through a thin non-metallic obstruction. The trade-off is that it is sensitive enough to be triggered by a moving branch or a passing car, so the position and the sensitivity setting both need thought.

Standby, hold time and override

The fitting ships with a remote that sets the lux threshold, the hold time and a standby level of 10%, 25% or 50% so instead of switching fully off between detections, it can idle dim and lift to full output when someone approaches. A manual override is also provided for the nights you simply want it on. That standby control is not the same thing as wall dimming: the fitting is not designed to run from a dimmer circuit, and the levels are set through the remote rather than a dimmer plate.

Output and colour

Both heads are tri-colour and set together at installation: 2 1,200lm at 3000K, 2 1,275lm at 4000K and 2 1,350lm at 5500K roughly 2,400 to 2,700lm from the fitting as a whole, at CRI>80. Each head tilts through 90 and swivels through 270, so the pair can be split to cover two directions from one point rather than doubling up on one.

Installation

UV-resistant polycarbonate body, semi-frosted glass lens, IP65 and IK06, surface mounted to a wall or ceiling with no cutout required. It runs on 240V AC direct to mains as a Class 2 fitting, so no earth is needed at the light and no driver is involved. Warranty is 3 years replacement.

Lights For You stocks this alongside the single-head Focus in both finishes, which is the practical way to mix sensor-switched and always-on positions on one elevation without the two fittings looking like different products.

Questions

How far does the sensor see, and how wide?

Havits data sheet for this model specifies a detection field of 180 and a range of up to 12m. Note that this is the sensors field of view, not the lights beam the beam angle is 120.

What kind of sensor is it?

A microwave sensor at 5.8GHz. It detects movement rather than body heat, so it triggers reliably in cold weather where a passive infrared sensor can miss a well-insulated person. It is also sensitive to moving branches and passing traffic, so aim and sensitivity are worth setting deliberately.

Can I stop it switching fully off between detections?

Yes. The supplied remote sets a standby level of 10%, 25% or 50%, so the fitting idles dim and lifts to full output on detection. The same remote sets the lux threshold and the hold time, and a manual override is provided.

Is it dimmable from a wall dimmer?

It is not intended to run from a dimmer circuit. Level control on this model is done through the supplied remote as a standby setting, which is a different mechanism from wall dimming.

How much light does it give in total?

Each head gives 1,200lm at 3000K, 1,275lm at 4000K or 1,350lm at 5500K, and there are two heads so between roughly 2,400 and 2,700lm from the fitting depending on the colour setting chosen at installation.

Can the two heads point in different directions?

Yes. Each head tilts through 90 and swivels through 270 independently, so one fitting can cover a path in one direction and a doorway in another.

What warranty applies?

Three years replacement, per Havits current data sheet for this model.
