Greenlight Solar LED Street Light SL 12W

Go Solar Systems LTD: Greenlight Solar LED Street Light SL 12W

The Greenlight SL 12A is the mid-range model in the Greenlight all-in-one solar streetlight series, delivering 1,200 lumens from a 12W LED array powered by a 16W polycrystalline solar panel and a 12V 14.4Ah lithium-ion battery. With a 12 to 16 hour discharge time and a higher installation height of up to 5 metres, the SL 12W is designed for wider-area applications where the lower-wattage models cannot deliver adequate coverage: internal estate roads, commercial car parks, warehouse yards, school compounds, and institutional campuses. The unit mounts on a standard lighting pole or wall bracket and operates autonomously from dusk to dawn with no grid connection.

Technical Specifications:

• LED output: 12W, 6000K-6500K colour temperature (cool daylight), 100 lm/W luminous efficacy (1,200 lumens total)
• Solar panel: 16W polycrystalline, integrated
• Battery: Lithium-ion, 12V 14.4Ah (12V system, significantly larger capacity than the 3W-6W models)
• Charging time: 5-6 hours (full sun)
• Discharge time: 12-16 hours
• Lamp dimensions: 555 x 305 x 55 mm
• Body material: polycarbonate and iron (PC Iron)
• Weight: 5 kg
• Installation height: 2-5 metres
• Mounting: pole-mount or wall-mount compatible
• Auto on/off via light sensor (dusk-to-dawn operation)
• Warranty: 2 years
• Certification: KEBS

Sustainability Features:

• Generates its own electricity from solar energy, eliminating grid electricity demand and associated Scope 2 carbon emissions for outdoor lighting
• Zero operational energy cost over the product’s lifetime, reducing long-term building operating expenses
• At 1,200 lumens, replaces a conventional 100W incandescent or 25W CFL streetlight while drawing zero grid power, representing a significant energy saving per fixture on a multi-luminaire estate lighting scheme
• No cabling, trenching, or electrical infrastructure required, reducing site disruption, copper use, and installation cost compared to grid-connected alternatives
• Extended 12-16 hour discharge covers the full overnight period in equatorial Kenya, maintaining continuous lighting without grid backup
• Lithium-ion battery avoids the lead-acid waste disposal burden of older solar lighting systems
