The Searchlight Black Line 77910-900 is a modern outdoor LED wall light designed to provide practical illumination along exterior walls, entrances and building facades. Standing 90 cm tall and just 6 cm wide, its slim vertical profile creates a distinctive architectural feature without projecting far from the wall. A sand black finish and frosted acrylic diffusers give the fitting a clean, contemporary appearance. The integrated 17W LED offers three selectable colour temperatures, making it possible to choose between warm and cooler white lighting. A built-in photocell sensor responds to changes in daylight, automatically operating the light when it becomes dark. With an IP65 rating for outdoor protection, Black Line is suitable for exposed exterior locations where automatic lighting, modern styling and a narrow wall-mounted design are important.
The Black Line collection features a minimalist, linear design with a strong architectural character. This 90 cm version has a tall, narrow rectangular body in a sand black finish, complemented by frosted acrylic light diffusers.
Its metal and acrylic construction combines a dark exterior frame with lighter illuminated surfaces, creating a noticeable contrast when switched on. The frosted diffusers soften the appearance of the integrated LEDs and help produce a more evenly illuminated surface.
Measuring only 6 cm wide with a projection of 4.8 cm, the fitting maintains a relatively shallow profile against the wall. Its understated design works particularly well with contemporary architecture, rendered walls, brickwork and modern entrance areas.
The Black Line 77910-900 incorporates a 17W integrated LED light source, so separate bulbs are not required. The elongated illuminated sections provide light along the fitting's vertical profile, while the frosted acrylic diffusers help reduce the direct appearance of individual LED components.
Three selectable colour temperatures provide flexibility for different exterior settings:
- 2700K - warm white light, suitable for creating a softer appearance around entrances and outdoor seating areas.
- 3300K - a slightly cooler warm white for general exterior illumination.
- 4000K - neutral white light for a clearer, more functional appearance around entrances and access routes.
The manufacturer specifies light outputs of 2,274 lumens at 2700K, 2,362 lumens at 3300K and 2,418 lumens at 4000K.
An integrated photocell sensor detects ambient daylight and automatically controls the light as surrounding conditions change. Unlike a PIR motion sensor, a photocell operates in response to light levels rather than movement.
The fitting is non-dimmable. Its IP65 rating provides dust-tight protection and resistance to water jets, making it suitable for exposed outdoor wall installations.

Does the Searchlight Black Line 77910-900 need separate bulbs?
No. This outdoor wall light has a built-in 17W LED light source, so there are no separate bulbs to purchase or install. The LED is integrated into the fitting rather than using a conventional replaceable bulb holder.
How does the photocell sensor work?
The integrated photocell detects changes in ambient daylight and automatically controls the light as it becomes dark or bright outside. It is a daylight sensor rather than a movement detector, so someone walking past is not required to trigger the light.
Can I change the colour of the light?
Yes. The integrated LED offers three selectable white colour temperatures: 2700K, 3300K and 4000K. These provide a choice between warmer and more neutral white illumination. The setting is intended to be selected as part of the fitting's configuration rather than through a colour-changing remote control.
Can this wall light be installed outdoors in the rain?
Yes. The Searchlight Black Line 77910-900 has an IP65 rating, providing protection against dust ingress and water jets. It is designed for outdoor wall installations, including exposed entrances and building facades. Installation must follow the manufacturer's instructions to maintain the specified weather protection.
Is the Black Line 77910-900 dimmable?
No. The manufacturer specifies this integrated LED wall light as non-dimmable. It does, however, offer three selectable colour temperatures, allowing the appearance of the white light to be adjusted without changing the brightness through a dimmer.

Understanding LED colour temperature and the Kelvin scale
Colour temperature 2000K to 3000K, the light produced is often referred to as a "warm white", "soft white", occasionally called a "candle white". It ranges from orange-ish to yellow-ish white in appearance. This kind of light is attractive, enjoyable, comfortable and relaxing.
Colour temperature 3100K to 4500K, the light produced is often referred to as a "neutral white", "bright white" or "natural white". Light sources within this range will emit a more neutral white light and may even have a slightly blue tint. This kind of light is bright, vibrant and clean appearing.

Colour temperature 4600K and above, the light produced is often referred to as a "cool white", "pure white" or "day white". Light sources in this range will have a blue-ish white tint to them. The higher the number, the more blueish it will appear. This kind of light will appear crisp, invigorating and energetic.
