The Searchlight Black Line 77910-300 is a modern outdoor LED wall light in a sand black finish, designed to provide automatic lighting around entrances, doorways, pathways and exterior walls. Its slim rectangular shape measures 30 cm high and just 6 cm wide, making it suitable for locations where a compact, architectural fitting is preferred. Frosted acrylic panels soften the appearance of the integrated LED light, while a built-in photocell sensor automatically switches the fitting on at dusk and off at dawn. The 7W integrated LED offers a choice of warm white, intermediate white and cool white light settings. With an IP65 rating for outdoor protection, Black Line combines a discreet appearance, practical exterior lighting and convenient automatic operation without requiring separate light bulbs.
The Black Line wall light has a narrow, vertical rectangular profile with clean edges and a contemporary architectural appearance. Its sand black finish creates a simple, understated look that works particularly well against rendered walls, brickwork and modern exterior cladding.
Constructed from metal and acrylic, the fitting incorporates frosted acrylic panels that diffuse the integrated LED light. The combination of a dark exterior and illuminated panels creates a clear contrast when the light is switched on.
At 30 cm high and 6 cm wide, with a projection of only 4.8 cm, the fitting sits close to the wall without a large projecting arm or decorative housing.
The Searchlight Black Line features a built-in 7W LED light source, so there is no need to purchase or install a separate bulb. Light passes through the frosted acrylic panels, helping to soften the brightness of the LED and provide illumination around the fitting.
Three selectable colour temperature settings allow the light appearance to be chosen during installation:
- 2700K - Warm white light for a softer, welcoming appearance.
- 3000K - Warm white light with a slightly clearer appearance.
- 4000K - Cool white light for a brighter-looking, more neutral effect.
The manufacturer lists light outputs of 810, 883 and 909 lumens across the three colour temperature settings.
An integrated photocell sensor detects changes in ambient daylight and automatically switches the light on when it becomes dark and off when daylight returns. This is a dusk-to-dawn sensor rather than a movement detector.
The fitting is non-dimmable. Its IP65 rating provides protection against dust and water jets, making it suitable for outdoor wall installation.
- Front entrances and doorways requiring automatic dusk-to-dawn lighting.
- Exterior house walls where a slim, modern design is preferred.
- Garden pathways and access routes alongside buildings.
- Patio and terrace walls requiring decorative exterior illumination.
- Contemporary homes with rendered, brick or clad facades.
- Side entrances and outdoor access areas where automatic operation is useful.
- Exterior locations requiring an IP65-rated wall fitting.
- Integrated 7W LED - provides illumination without the need for a separate replaceable bulb.
- Built-in photocell sensor - automatically operates the light according to surrounding daylight levels.
- Three colour temperature settings - offers a choice of 2700K, 3000K or 4000K to suit the installation.
- IP65 protection - provides a high level of resistance to dust and water ingress for exterior use.
- Sand black finish - creates a discreet, contemporary appearance on exterior walls.
- Frosted acrylic panels - diffuse the LED light and reduce the direct visibility of the light source.
- Slim 6 cm width - makes the fitting suitable for relatively narrow sections of wall.
- Shallow 4.8 cm projection - keeps the light close to the mounting surface.
- Class I construction - designed for an earthed mains electrical connection.
- Automatic dusk-to-dawn operation is useful for entrances and outdoor areas where lighting is needed after dark.
- The compact rectangular design suits modern architectural exteriors without introducing bulky decorative features.
- Selectable light colours provide flexibility when coordinating exterior lighting with the surrounding property.
- Integrated LED technology removes the need to select a compatible bulb or replace conventional lamps.
- The IP65 rating makes the fitting suitable for exposed outdoor wall locations when correctly installed.
- The combination of a narrow body and shallow projection offers a practical solution where wall space is limited.

Does the Searchlight Black Line 77910-300 switch on automatically?
Yes. The light has a built-in photocell sensor that responds to the surrounding daylight level. It automatically switches on when it becomes dark and switches off when daylight returns. The sensor detects light levels rather than movement, making it suitable for automatic dusk-to-dawn exterior lighting.
Can I change the colour of the light?
Yes. The integrated LED offers three selectable colour temperature settings: 2700K, 3000K and 4000K. These provide different shades of white light, from warm white to cool white. The colour temperature is selected using a switch on the fitting during installation, rather than through a remote control.
Is the Black Line 77910-300 suitable for outdoor use?
Yes. Searchlight specifies an IP65 rating, meaning the fitting is dust-tight and protected against water jets. It is designed for outdoor wall mounting and can be installed in exposed exterior locations when fitted correctly in accordance with the manufacturer's installation instructions.
Do I need to buy a bulb for this outdoor wall light?
No. The Black Line 77910-300 includes an integrated 7W LED light source. There is no conventional bulb holder, so a separate E27, GU10 or other replaceable bulb is not required. The LED is built into the fitting.
Is this outdoor LED wall light dimmable?
No. The Searchlight Black Line 77910-300 is specified as non-dimmable. Its three colour temperature settings change the shade of white light rather than adjusting its brightness. The built-in photocell sensor controls automatic switching according to daylight levels.

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.
