The ILED-BH-R20W is the base model of the Halo 300mm bulkhead family: a round ceiling-or-wall fitting for corridors, stairwells, carparks and building perimeters, where a sealed, impact-resistant light does the everyday work. Two outputs share the same body, so a building can run the brighter version where the ceiling is higher and the standard one everywhere else without changing the look. It is the fitting most people mean when they say bulkhead: round, sealed, tough, and mounted where the traffic is.
Two outputs, one body
The 20W version puts out 2200 lumens and the 30W version 3300, both at 110 lumens per watt from LumiLEDs LM80 sources. The LED source is LM80-rated, which is the rating that says the chips have been tested for how their light holds up over time. Colour temperature spans 2800K to 7000K at order — warm for residential corridors, cooler for service areas — with colour rendering above 80.
Build and mounting
The body is die-cast aluminium with a polycarbonate diffuser, gasket-sealed to IP65 against dust and water jets from any direction, and rated IK10 for impact — the top of the standard scale, which is what a fitting mounted at corridor or carpark height needs. The finish is white, black or grey painted. It is a surface mount for wall or ceiling, Class I wired, with the driver inside the body, so the install is the base plate, the terminal block and nothing else.
Voltage and control options
The fitting runs on 220-240VAC or 110-277VAC, so one product covers both regional supplies. Four functional versions are available factory-fitted: DALI dimming for buildings with a control system, a motion-sensor version, a standby motion-sensor version that runs the light at a low level until someone passes, and an emergency version that keeps the fitting lit through a power outage. These are fitted at the factory — they are not field retrofits, so the IP65 seal is never opened on site.
What you need to supply
You need the wall or ceiling fixings suited to the surface and a switched circuit with a protective earth for the Class I connection. For a DALI version, the DALI power supply and controller are separate purchases; for the emergency version, the circuit must sit on the board that stays live for battery charging. An electrician handles the hardwired connection per local code.
The 300mm family
This standard model is one of three on the same body. The MC version adds a microwave detector with the emergency function, for areas that need the light to come on without anyone touching anything. The Tri Guard version carries a reinforced cover over the diffuser for the positions that take harder hits. All three keep the same φ300×90mm silhouette and the same output options, so a building can step up the protection per area while the ceiling still reads as one scheme.
Where it gets used
Corridors and stairwells in schools, offices and housing are the bread-and-butter positions. Carparks and loading bays take the IK10 body and the IP65 seal, day in and day out. Building perimeters and entrance ways use it as the weather-sealed amenity light, and with the DALI or sensor versions the running hours drop without anyone touching a switch. The anti-salty finish suits coastal installations where repainting is the usual cost.
Certifications and warranty
The ILED-BH-R20W carries SAA for Australia and New Zealand, CE and RoHS for Europe, and TUV. The warranty runs three to five years depending on the region and version ordered. The sealed body needs no routine work inside; a wipe of the diffuser face during site maintenance keeps the output even.
