Square Bulkhead Light LED 20 30 Watt IP65 Wall Packed Photocell Wall Packed Emergency

The ILED-BH-S20W-A is a square IP65 bulkhead light built for wall mounting on building exteriors where automatic light control and emergency backup are needed. Unlike surface-mounted photocells that can be vandalised or missed by rain, the photocell is factory-installed inside the housing — it senses ambient light and switches the fixture on and off automatically. The emergency battery kicks in the moment mains power fails, providing fallback illumination for walkways and entrances.

Tech specs at a glance

The ILED-BH-S20W-A runs at 30W and produces 3000 lumens at 100 lumens per watt. It accepts 220-240VAC or 110-277VAC 50/60Hz input. The colour temperature is fixed between 2800K and 6500K at installation — choose warm, neutral or cool white depending on the application. Colour rendering is above 80. The beam angle is 120°, spreading light evenly across the area below. The housing measures 308×265×126mm, larger than the round R20W sibling. The opal polycarbonate diffuser scatters light softly with no harsh glare points. The body is powder-coated black — the only finish offered for this wall-packed variant.

Wall-packed photocell

The photocell is built into the housing, not added as an external sensor. It detects ambient light levels and switches the fixture on at dusk and off at dawn automatically. Because it is sealed inside the IP65 enclosure, it is protected from rain, dust and vandalism. No separate controller, timer or wiring to an external light sensor is needed.

Emergency function

The ILED-BH-S20W-A includes a wall-packed emergency battery. When mains power is lost, the fixture automatically switches to battery mode and continues to illuminate at reduced output for a rated duration. The emergency function operates independently of the photocell — if power fails during daylight, the light still activates on battery when conditions require. The emergency battery is tested automatically on each charge cycle.

Build and installation

The housing is aluminium with a black powder-coated finish. The diffuser is opal polycarbonate, which provides soft glare-free light spread. The integral driver, emergency battery and photocell are all sealed inside the housing. Wiring is direct to mains through the terminal block. Electrical classification is Class I, requiring a protective earth connection. The fixture mounts to a flat wall or soffit using the four mounting points on the back plate. For recessed mounting, cut a 308×265mm opening in the wall surface.

Control options

This fixture has no DALI, DMX or remote control capability. It is controlled by the integrated photocell (on/off based on ambient light) and a standard wall switch or circuit breaker. For projects requiring motion sensing or DALI dimming, order the non-emergency variants from the same series instead.

What is in the box

Each unit ships as a single bulkhead with the driver, emergency battery and photocell pre-installed. Mounting hardware and the terminal block are included. No separate sensor module, transformer or emergency converter is packed inside — the fixture is ready to wire direct to mains.

Where it gets used

The ILED-BH-S20W-A is built for exterior wall mounting where automatic operation and emergency backup are both required. Building perimeters and entryways use the photocell for hands-free dusk-to-dawn operation. Security lighting at loading bays and rear entrances benefits from the emergency function — the area stays lit if the main supply is cut. Corridor and passage lighting in commercial buildings uses the black finish to blend with brickwork. The opal diffuser provides even, glare-free illumination suitable for CCTV-covered areas.

Certifications and warranty

The ILED-BH-S20W-A carries SAA, CE and RoHS certifications. SAA approval covers Australian and New Zealand market requirements. The warranty period is three to five years depending on the region and distributor terms.

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

Wall-packed photocell, not add-on. Many competitors sell a bulkhead and expect you to wire an external photocell separately. The ILED-BH-S20W-A has the sensor factory-installed inside the IP65 housing — no extra wiring and no external sensor to vandalise or expose to weather.

Built-in emergency backup. The integrated battery means no separate emergency converter box is needed. The fixture switches to battery mode automatically on mains failure, and the photocell keeps working on backup power.

Black finish as standard. Most IP65 bulkheads come in white. The black powder-coated body blends into brickwork and dark fascia, making it less visible on building exteriors — preferred for heritage buildings and modern facades.

Opal diffuser for even light spread. The opal polycarbonate diffuser scatters light softly with no hot spots or glare. This is particularly useful for CCTV-covered areas where a clear diffuser would cause lens flare and reduce camera image quality.

The Square Bulkhead Light LED 30W IP65 with Wall-Packed Photocell and Emergency (ILED-BH-S20W-A) is designed for wall mounting on building exteriors where automatic operation and backup illumination are required.

Building perimeters and entryways. The wall-packed photocell provides hands-free dusk-to-dawn operation without external wiring. The emergency battery ensures the entrance stays lit during power failures, meeting fire safety requirements for escape routes.

Security lighting at loading bays and rear entrances. The black finish blends into brickwork and dark fascia. IP65 weatherproofing handles rain and washdown. The emergency function maintains illumination if the main supply is cut during a power failure.

Corridor and passage lighting in commercial buildings. The opal diffuser provides even, glare-free illumination without hot spots. The black body is less visible on exterior walls than white fixtures, which is preferred for heritage buildings and modern architectural facades.

CCTV-covered areas and car park boundaries. The opal polycarbonate diffuser scatters light softly, reducing lens flare that would otherwise degrade camera image quality. IP65 weatherproofing ensures reliable operation in exposed outdoor locations.

Walkways and pedestrian routes. The 120° beam angle spreads light evenly across walkways. The emergency function provides backup illumination along escape routes if mains power fails.

A few things to check before ordering:

Voltage compatibility. This fixture accepts 220-240VAC or 110-277VAC 50/60Hz. Confirm your local mains voltage.

Impact rating. The ILED-BH-S20W-A is IP65 rated only — it does not carry an IK impact rating. If the installation location is subject to physical impact, order the IK10-rated sibling (ILED-BH-S20W) instead.

Colour temperature. The range spans 2800K to 6500K. Set the desired colour temperature at installation — it cannot be changed after the diffuser is sealed. Confirm the specification before ordering if a specific temperature is required.

Mounting type. The fixture is designed for surface mounting on flat walls or soffits. For recessed installation, cut a 308×265mm opening. 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-A lists SAA on its specifications table.
