Square Weatherproof IP65 IK10 LED Bulkhead Ceiling Light

The ILED-BH-S20W is a square bulkhead light designed for ceiling or wall mounting in environments where water resistance and impact protection matter. The die-cast aluminium body gives it the structural strength to survive bumps, vibration and rough handling, while the IK10-rated polycarbonate lens means accidental contact from carts, ladders or stored materials will not crack the diffuser. This is why it appears so frequently in car parks, warehouses and utility areas where fixtures take a beating.

Tech specs at a glance

The ILED-BH-S20W comes in two wattage options. The 20W version produces 2200 lumens at 110 lumens per watt. The 30W version steps up the output proportionally while keeping the same 110LM/W efficacy. Both run on 220-240VAC or 110-277VAC 50/60Hz mains, so the fixture works in most regions without a transformer. The colour temperature is selectable at installation — choose between 2800K warm white, 4000K neutral and 6500K cool white. Colour rendering sits above 80, which is sufficient for task and general illumination. The 120° beam angle spreads light evenly across the floor without creating narrow hot spots. IP65 rating keeps dust and water jets out; IK10 rating means the lens survives a 5 joule impact — roughly a 500-gram weight dropped from 1 metre.

Build and installation

The housing is die-cast aluminium, finished in white or black powder coat. The diffuser is anti-UV polycarbonate, rated IK10, mounted with a gasketed seal that maintains the IP65 rating when the fixture is closed. The integral driver is sealed inside the aluminium body — no external ballast or separate power supply is needed. Wiring is direct to mains through the terminal block inside the housing. The fixture can be surface-mounted to a flat ceiling or wall using the four mounting points on the back plate, or recessed into a 300×300mm cutout if the ceiling construction allows. Electrical classification is Class I, meaning it requires a protective earth connection.

Control options

This is a standard non-dimmable, non-controlled bulkhead. It switches on and off with the circuit — wall switch, sensor, or timer — with no dimming or DALI capability built in. If your project requires motion sensing, photocell control or DALI addressing, order the wall-packed or emergency variants from the same series instead.

What is in the box

Each unit ships as a single bulkhead with the driver pre-installed, mounting hardware included and the terminal block ready for connection. The anti-UV PC lens is factory-fitted and should not be removed after installation. No separate controllers, transformers or drivers are packed inside — the fixture is ready to wire direct to mains.

What you need to supply

A circuit breaker or wall switch for on/off control. A suitable ceiling or wall mounting surface that can support the fixture weight. For outdoor or wet-location installations, confirm the mounting location is within the IP65 protection zone and that the seal remains intact after installation. No special tools beyond a screwdriver and wire strippers are required.

Where it gets used

The ILED-BH-S20W is built for areas where the fixture is exposed to impact, moisture or harsh conditions. Car parks and undercroft parking benefit from the IK10 lens and IP65 seal — the fixture survives the occasional impact from vehicle doors and handles rain runoff without failure. Warehouse aisles and storage areas use it for general illumination where overhead fixtures are vulnerable to forklift contact. Outdoor walkways, loading bays and service corridors take advantage of the wide 120° beam and the two-wattage range to cover both tight utility spaces and broader open areas from the same product line. The 3CCT option lets a single SKU serve warm-white hospitality entrances and cool-white security zones on the same project.

Certifications and warranty

The ILED-BH-S20W carries SAA, CE and RoHS certifications. The SAA approval covers Australian and New Zealand market requirements, which is notable since many competitors in this category only list CE. The warranty period is three to five years depending on the region and distributor terms.

Lifespan and maintenance

The LumiLEDs LM80 source is rated for extended operation with lumen maintenance above the typical decay curve for commercial bulkhead lights. The sealed IP65 housing means no routine cleaning of internal components is required. Occasional external wiping of the PC diffuser with a damp cloth is sufficient to maintain light output. The anti-UV treatment on the lens prevents yellowing over time, keeping illumination levels stable throughout the rated lifespan.

Why do buyers pick these over the alternatives? Here is what we hear from customers:

IK10 impact rating. Most bulkheads in this size range carry IK08 or IK09. The ILED-BH-S20W goes to IK10, which means it survives a 5-joule impact — roughly a 500-gram object dropped from 1 metre. In car parks and warehouses where fixtures take accidental hits, that extra rating matters.

Die-cast aluminium body. The housing is cast aluminium, not extruded or stamped. Cast alloy gives better structural integrity and heat dissipation, supporting the 110LM/W output and long-term lumen maintenance.

SAA, CE and RoHS in one SKU. The SAA certification covers Australian and New Zealand regulatory requirements. Many comparable bulkheads only list CE, meaning extra approval work for AU/NZ projects. Having SAA on the datasheet removes that step.

Two wattages, one housing. The 20W and 30W versions share the same 300×300×90mm enclosure and mounting pattern, so specifiers can order the lower output for tight corridors and step up to 30W for wider spaces without changing mounting hardware.

The Square Weatherproof IP65 IK10 LED Bulkhead Light (ILED-BH-S20W) is designed for ceiling and wall mounting in environments where impact resistance and weather protection are required.

Car parks and undercroft parking. The IK10-rated lens survives impact from vehicle doors, luggage and shopping trolleys. IP65 protection handles rain runoff and washdown without internal condensation. The 120° beam spreads light evenly across parking bays and driving lanes.

Warehouse aisles and storage areas. Overhead bulkheads in warehouses are vulnerable to forklift contact and shelving impact. The die-cast aluminium body and IK10 lens absorb blows that would crack lighter fixtures. IP65 dust protection keeps light output stable in dusty environments.

Outdoor walkways and entry canopies. Covered walkways, entrance canopies and porte-cocheres expose fixtures to rain and foot traffic. The IP65 seal and IK10 lens handle both conditions. The 3CCT option lets specifiers match warm-white hospitality entrances with cool-white security zones.

Loading bays and service corridors. These areas combine moisture, dust and physical impact. The sealed aluminium housing and gasketed PC diffuser keep internal components clean and dry. The 20W/30W range covers both narrow corridors and bay areas from the same housing.

Utility rooms and plant areas. Boiler rooms, electrical rooms and mechanical spaces require rugged, maintenance-light fixtures. The sealed driver and anti-UV lens mean these areas get reliable illumination without frequent replacement.

A few things to check before ordering:

Wattage selection. The 20W version delivers 2200 lumens; the 30W version steps up proportionally at the same 110LM/W. Choose based on illumination level — 20W for narrow corridors and utility areas, 30W for wider car parks and open storage zones.

Colour temperature. Three fixed settings are available at installation: 2800K warm white, 4000K neutral and 6500K cool white. Set the switch before closing the diffuser — it cannot be changed after installation.

Finish selection. White and black housing finishes are available. White is standard. Black suits car park ceilings and modern architectural interiors where a lower-visibility fixture is desired.

Mounting type. The fixture can be surface-mounted to any flat ceiling or wall, or recessed into a 300×300mm cutout. Confirm the mounting surface supports the fixture weight and that the IP65 seal remains intact after installation.

SAA compliance. If the project requires SAA approval for Australian or New Zealand markets, confirm this variant carries the certification before ordering. The ILED-BH-S20W lists SAA on its specifications table.
