A sensor kit that lets a Springbok Lite think for itself This is Collingwood's microwave sensor kit, code HBLMWS, built specifically for the Springbok Lite high bay range. It fixes a 5.8GHz motion sensor onto the fitting so the light only runs when somebody is actually underneath it, and it adds a daylight threshold so the high bay will stay off through a bright morning even when the space below is busy. On a building full of high bays that currently burn all shift, it is one of the simplest ways to stop paying for light nobody is using. Black hardware made to sit on the fitting Every part of the kit is finished in black to match the Springbok Lite itself, so the sensor head, the junction box and the brackets read as part of the luminaire rather than as bolt on clutter. The sensor is a squat cylindrical housing on a short flying lead, clamped to its bracket. The junction box is a sealed black enclosure with cable glands along one side for the supply. Between them sit flat steel mounting plates, a pair of half moon counterweights and a set of stainless steel screws and nuts. None of it is decorative. It is plain industrial hardware that pairs with one thing, the Collingwood Springbok Lite high bay. How It Works The sensor uses 5.8GHz microwave detection, which reads movement rather than body heat, so it picks up people and vehicles across an open floor. When it senses motion it switches the high bay on. Once the area clears and the hold time expires, it switches it off again. Hold time is selectable at 30 seconds, 1 minute, 3, 5, 10, 20 or 30 minutes, so a busy loading bay and a rarely visited racking aisle can behave completely differently. The daylight threshold is the second half of the job. Set it to 2, 10, 30, 50, 80 or 120 lux and the sensor will not bring the light on while ambient daylight sits above that level. It arrives with the threshold disabled, so you switch it on deliberately at commissioning. Detection area can also be pulled back to 75, 50 or 25 percent of full coverage if the sensor is picking up movement in a neighbouring aisle it should be ignoring. All of those settings are commissioned by remote, so they can be changed from the floor rather than at the fitting. Collingwood lists the kit contents as the microwave sensor, a junction box for cabling and a counterweight for balance, and quotes a typical installation height of 8 to 15 metres. The complete kit weighs 1.5 kg. Where It Works Best This is either a retrofit for a Springbok Lite high bay that is already hanging or an item specified at the point of order. It mounts onto the body of the luminaire, with the sensor on one arm and the junction box on the other, and it wires into the mains feed to that fitting so the sensor sits between the supply and the light. Warehouses and distribution sheds are the obvious home for it, especially racking aisles that only see a picker now and then. Workshops, factory floors, MOT bays, sports halls and agricultural buildings all suit it just as well, anywhere with a high roof, intermittent occupancy and lighting that would otherwise run all shift. It earns its keep fastest in a building with plenty of roof lights, where the daylight threshold does much of the saving on its own. About Collingwood Lighting Collingwood designs and manufactures its LED products from Sywell in Northamptonshire, and has worked in LED technology since 2002, which in this trade counts as a very long run. The brand states it was among the first to bring fire rated, fully sealed for life and mains dimmable LED products to the UK electrical wholesale market. It has also been awarded an EcoVadis Gold medal, placing it in the top 5 percent of companies assessed worldwide for sustainability. On a product whose entire purpose is to cut the energy a building spends on lighting, that focus is rather the point. Good to Know Backed by a 4 year Collingwood warranty. Rated IP65, which means it is fully protected against dust and against low pressure water jets from any direction, so dusty and damp industrial spaces are no trouble. That IP65 sealing also sits well above the ingress protection required for bathroom zones, so it is suitable for bathroom use. Our guide to bathroom lighting zones explains how the zones are set out. Collingwood supplies this as a Springbok Lite accessory, so it is designed around that fitting rather than as a universal sensor. This is an on/off sensor. It switches the high bay rather than dimming it, so it is not a replacement for a dimming control system. Hold time, daylight threshold and detection area are all set by remote, which means they can be adjusted after installation without dropping the fitting. Collingwood quotes a typical installation height of 8 to 15 metres. The kit weighs 1.5 kg, and the supplied counterweight balances that load so the high bay still hangs level. Give the sensor lens a wipe now and then. Dust settling on a high bay sensor is the usual reason one starts responding slowly. Moonlight Design recommends installation by a registered NICEIC electrician. Questions People Ask What does the Collingwood Springbok Lite microwave sensor kit do? The Collingwood HBLMWS microwave sensor kit adds 5.8GHz motion detection and an adjustable daylight threshold to a Collingwood Springbok Lite LED high bay, switching the light on when movement is detected below the fitting and holding it off when there is already enough natural light in the space. How long does the light stay on after movement stops? The hold time on the Collingwood HBLMWS microwave sensor kit is selectable at 30 seconds, 1 minute, 3 minutes, 5 minutes, 10 minutes, 20 minutes or 30 minutes, and is chosen at commissioning to suit how the space is used. Does the HBLMWS sensor kit dim the high bay? No. The Collingwood HBLMWS is an on/off microwave sensor kit, so it switches a Springbok Lite high bay fully on and fully off and does not provide dimming or step dimming. What is included in the Collingwood microwave sensor kit? The Collingwood HBLMWS kit contains the 5.8GHz microwave sensor head on a flying lead, a sealed junction box with cable glands for the wiring, steel mounting brackets, a counterweight to keep the Springbok Lite high bay hanging level, and stainless steel fixings. What height should the sensor be installed at? Collingwood gives a typical installation height of 8 to 15 metres for the HBLMWS microwave sensor kit, which reflects the high roof spaces the Springbok Lite high bay range is built to light.
