Solar Lighting Designs | Solar Billboard Light 3 x 35W LED 21000lm | Powder-Coated Black Aluminium
The Solar Lighting Designs SOLLBB-105 is a solar powered billboard light with three 35W LED modules, rated 21000 lumens combined at 6000K. The SOLLBB-105 runs from a 100W solar panel and a 576Wh LiFePO4 battery, with 2 to 3 nights of autonomy on a full charge. It illuminates automatically at dusk and follows a programmed output cycle through to dawn.
A wide sign face lit by a single head reads as a bright centre with dark corners, and the artwork at the edges disappears from the road. Correcting that on a mains installation means additional fittings, additional cable, and trenching to a location with no distribution nearby. The SOLLBB-105 addresses both constraints together. Three pivoting 35W heads distribute the output across the face, while a 100W panel with a 576Wh LiFePO4 battery carries the load with no mains connection required.
Quoting an off-grid signage luminaire against a mains run changes the shape of the whole job. Trenching and switchboard work disappear, so the labour reduces to bracket fixing and beam alignment. Solar Lighting Designs supplies the SOLLBB-105 as a plug and play system, with the panel, cables, and brackets included. That shortens the materials list and keeps the quotation clean. The 1000mm outreach arm holds the heads clear of the face, so a single part number suits signage illuminated from above or below.
Features
- Triple 35W LED modules — the SOLLBB-105 carries three Philips LED heads rated 35W each, delivering 3 x 7000 lumens for 21000 lumens combined.
- 210 lumen per watt output — high-efficacy Philips LEDs turn the stored charge into light on the sign face rather than waste heat.
- 100W solar panel — the SOLLBB-105 charges from a 100W panel, with a full recharge in around 5 hours of good sun.
- 576Wh LiFePO4 battery — lithium iron phosphate storage carries 2 to 3 nights of operation on a full charge.
- Programmed mode of operation — the default program runs 100% output for 2 hours, 80% for 3 hours, then 25% output until dawn.
- Automatic dusk to dawn operation — the SOLLBB-105 illuminates at dusk under its own control and runs the cycle through the night.
- Three pivoting heads — each module pivots independently, so the beams can be spread across a wide face or grouped on a narrow one.
- 1000mm outreach arm — the adjustable bracket holds the heads a metre off the face for even coverage from above or below.
- Sealed aluminium body — fully sealed aluminium housing in a powder-coated black finish for permanent outdoor mounting.
- Complete system supplied — solar panel, cables, mounting brackets, and the pivoting LED fixtures are included for most installations.
- Output tied to battery charge — lumen output is directly related to battery charge, so extended overcast weather reduces both brightness and runtime.
- Two-year warranty — covers faulty workmanship or component failure not influenced by external means, running from the invoice date.
Where to use
- Roadside billboards — the SOLLBB-105 puts 21000 lumens across a board at highway sight distance with no supply connection to arrange.
- Wide-format business signage — three heads cover a long shopfront or fascia sign that a single fitting would light unevenly.
- Sports club sponsor boards — lights perimeter and scoreboard signage at grounds where power stops at the clubhouse.
- Estate and building entry statements — the SOLLBB-105 mounts to entry signage at the front boundary, usually the furthest point from any supply.
- Rural and remote signage — property, tourism, and roadhouse signs run off-grid on the 100W panel and 576Wh battery.
- Industrial sites and depots — lights gate and site identification signage without trenching across hardstand or traffic areas.
- Sites awaiting mains connection — signage can be lit from handover night while the permanent supply works through approvals.
Solar Lighting Designs rates this system for small to medium billboards and signs, not for area lighting, car park lighting, or sports field lighting. Lumen output is directly related to battery charge, so brightness and runtime both fall away when charging is interrupted. The 100W panel needs clear sun through the day, which makes positions under tree cover, awnings, or building overhangs poor candidates.
