Square LED Bulkhead Light Grille Crossing 15W 18W 270mm Aluminium Waterproof IP65

The ILED-BH-R275-GL S is a square LED bulkhead light designed for exterior and covered outdoor environments where consistent, glare-controlled illumination is required. The grille crossing diffuser — a frosted cross-hatch pattern molded into the polycarbonate cover — softens the light output and reduces direct glare, making this variant particularly suited to corridors, walkways, and entrances where harsh point-source light would be uncomfortable. Unlike the round R275 bulkhead (ILED-BH-R275), the square 270×270mm form factor aligns with rectangular ceiling tile grids and modern architectural lines, giving installers a clean geometric fit that a round housing cannot match.

Tech specs

The 15W version delivers 1400 lumens and the 18W version delivers 1700 lumens, both at a rated 90–100 lumens per watt using LumiLEDs LM80-certified chips. The 3CCT switch lets you select 2800K warm white, 4000K neutral white, or 6500K cool white at installation — one SKU covers the three most common colour temperatures without needing separate stock. Input voltage accepts either 220–240VAC or 110–277VAC at 50/60 Hz, which gives flexibility for projects in different regions. The power factor is above 0.9, meaning the driver draws current efficiently without unnecessary reactive power. The die-cast aluminum housing measures 270×270×86mm and is rated IP65 for dust and water ingress plus IK10 for impact resistance, so it survives accidental knocks from maintenance ladders, carts, or falling debris. Body colour options are white, black, and silver gray, allowing the fitting to blend or contrast with the surrounding facade. A beam angle of 120° gives a wide, even wash across the target area. The class I construction requires a protective earth connection.

Grille crossing diffuser — what it does

The GL suffix stands for Grille Crossing, which refers to the micro-prismatic cross-hatch pattern built into the diffuser panel. This pattern breaks up direct line-of-sight to the LED chips while still passing a high proportion of the light through. The result is a softer, more evenly distributed beam that feels comfortable to look toward — important in spaces where people pass directly underneath the fitting. Compared with the plain diffuser (ILED-BH-R275 S), which gives the highest raw lumen output, the grille crossing version trades a small amount of peak brightness for significantly better visual comfort. Compared with the eyelid half-moon version (ILED-BH-R275-EL S), which adds a shroud for the lowest glare, the grille crossing offers a middle ground: good light quality without the deep recessed look. The crossing pattern also hides individual LED points from oblique viewing angles, giving a cleaner appearance when viewed from below at an angle.

Optional features

Three factory-installed options are available for the ILED-BH-R275-GL S: an emergency battery pack that provides approximately 90 minutes of backup illumination on mains failure, a DALI dimming driver for integration into building management systems, and a standby motion sensor for presence-reactive lighting. These options must be specified at the time of order because they are installed during manufacturing and cannot be added in the field. The emergency and DALI variants carry the same IP65 and IK10 ratings as the standard version — the internal components are sealed within the same housing.

Packaging and installation

Each unit weighs 2.2 kg net and ships 10 pieces per carton at 24.8 kg gross, in a carton measuring 60×54×32 cm. The square housing mounts to a standard junction box with the provided fixing screws, and the terminal block accepts both wire and clamp connections. Because the input voltage range covers both 220–240VAC and 110–277VAC, no transformer or voltage converter is needed for most international installations.

Why do buyers pick the ILED-BH-R275-GL S over the alternatives? Here is what we hear from customers:

Square form factor. — 270×270mm fits modern rectangular ceiling layouts and contemporary facades better than a round housing. Installers note the visual alignment with tile grids and cladding patterns.

Grille crossing glare control. — The frosted cross-hatch diffuser reduces direct glare without sacrificing too much output. It sits between the plain version (maximum brightness) and the eyelid version (maximum glare reduction), which many specifiers describe as the “just right” option for corridors and entrance canopies.

IK10 impact rating. — The die-cast aluminum body and reinforced diffuser give IK10 protection, important for car parks, loading bays, and areas where equipment or carts may contact the fitting.

Wide voltage acceptance. — 220–240VAC and 110–277VAC both work, so the same SKU is usable across regions without re-specifying.

Factory options. — Emergency, DALI, and motion sensor are all available as factory-installed modules, so there is no need for field retrofits that can compromise the IP65 seal.

Corridor and hallway lighting. — The glare-reduced output of the grille crossing diffuser makes this bulkhead ideal for long interior corridors in offices, hospitals, and schools, where occupants look up repeatedly and direct LED points would cause discomfort.

Entrance canopies and porte-cochères. — IP65 and IK10 ratings handle rain, vehicle spray, and occasional impacts. The square housing aligns with modern architectural entries that favour geometric forms over round fixtures.

Car park aisles and pedestrian walkways. — 1700 lumens on the 18W model provides sufficient illumination for vehicle aisles and foot-traffic routes. The 120° beam angle covers a wide strip beneath each fitting, reducing the number of units needed.

Warehouse receiving bays and loading docks. — IK10 impact resistance handles the occasional bump from fork-lift masts or rolling crates. The wide voltage range (110–277VAC) accommodates facilities in different countries without re-specifying.

Retail back-of-house and service corridors. — The grille crossing diffuser provides even, shadow-free light for stock handling and inventory movement, while the slim 86mm depth keeps the fitting unobtrusive in low-ceiling spaces.

Educational building circulation spaces. — Corridors, stair landings, and locker rooms benefit from the balanced glare control and the option to specify standby motion sensor for energy savings during unoccupied periods.

A few things to check before ordering the ILED-BH-R275-GL S:

Diffuser type. — Confirm whether Grille Crossing is right for your space. If the fitting will be looked at directly for extended periods, the eyelid (EL) version may be more comfortable. If maximum brightness is the priority, the plain diffuser gives more lumens.

Body colour. — White, black, and silver gray are available. Choose the colour that matches or blends with the surrounding facade or ceiling.

Voltage range. — Both 220–240VAC and 110–277VAC are accepted, so no transformer is needed for North American or Asian installations. Verify the local mains voltage anyway.

Factory options. — Emergency battery, DALI driver, and motion sensor must be specified at order time. They cannot be added after manufacture.

Packaging. — 10 pieces per carton, 2.2 kg net per unit, 24.8 kg gross, carton size 60×54×32 cm.
