Collingwood Daylight Sensor for Area Bay Luminaires

Let the Daylight Do Some of the Work

Warehouses and industrial units often get decent daylight through roof lights or windows for part of the day, yet the lighting still runs at full output whether it is needed or not. This sensor changes that. Fitted into a Collingwood Area Bay luminaire, it reads the natural light in the space and holds the fixture back when there is already enough brightness around, only calling for full output once daylight drops away.

A Simple Plug In Sensor

The sensor is a compact black photocell housed in a ribbed twist cap, small enough to sit flush in the centre of the luminaire it is fitted to. It clicks into the standard Zhaga socket built into compatible Area Bay fittings, so there is nothing extra to wire in and no separate bracket or enclosure to source.

How It Works

• A photocell in the sensor constantly measures the ambient light level in the space
• You set the lux threshold you want the luminaire to react to
• Once daylight falls below that threshold, the luminaire brings itself up rather than switching straight to full brightness
• Dimming runs over 0 to 10V or PWM, so the change between daylight and electric light is gradual

Where It Works Best

This is built for the kind of high ceilinged spaces the Area Bay range is designed for, warehouses, distribution centres, workshops and factory floors, especially where roof lights or large windows bring in changeable daylight through the day. Fitting one to the luminaires nearest those daylight sources is where the savings show up first, since those are the fittings most likely to be running at full output when they do not need to be.

Collingwood Lighting

Collingwood has been developing LED lighting technology since 2002, designing and manufacturing from its base in Sywell, Northamptonshire. The brand says it was among the first to bring mains dimmable LED products of this kind to the UK electrical wholesale market, and daylight harvesting sensors like this one sit within that same push toward lighting that only draws power when it is actually needed. Collingwood has also been awarded a Gold medal by EcoVadis, placing it in the top 5% of companies assessed globally for sustainability.

Good to Know

• Rated IP65, suited to the industrial and warehouse environments Area Bay luminaires are typically installed in
• Supports 0 to 10V and PWM dimming for a gradual rather than stepped change in light output
• Fits directly into the Zhaga socket on compatible Area Bay luminaires, no separate wiring required
• Comes with a 5 year warranty
• Weighs 0.1kg

Questions People Ask

Will this work with any Area Bay luminaire?

It is designed for Collingwood Area Bay luminaires fitted with the standard Zhaga socket, so check your specific luminaire has that socket before ordering.

Do I need an electrician to fit it?

No extra wiring is needed since it plugs directly into the Zhaga socket already built into the luminaire, though the luminaire itself should always be installed by a qualified electrician.

What lux level does it react to?

You set your own threshold on the sensor, so it can be tuned to the daylight conditions of the specific space it is installed in.

Does it dim the light gradually or just switch it on and off?

It supports 0 to 10V and PWM dimming, so the luminaire ramps up and down gradually as daylight changes rather than switching abruptly.
