Ask a contractor in Lagos what killed the last lighting budget and you rarely hear "the lamps were too expensive". You hear about cable - copper, conduit, trenching, a transformer upgrade, and a connection approval that lands after the road is already paved.

That one line item is why the all-in-one solar garden light went from niche to default in Africa. A lamp that arrives with its own panel, battery and controller and mounts in twenty minutes beats a wired fixture that needs a crew, a machine and a permit.

What changed

LiFePO4 packs rated for 2000 cycles stopped doubling the lamp cost, and 5050 LEDs reached roughly 230 lumens per watt - so 40W now delivers 7200 lumens instead of 4000.

The LGH series, in plain numbers

40W, 60W, 80W and 100W on one housing: 70W to 160W monocrystalline panel, 36Ah to 80Ah LiFePO4, 7200 to 18000 lumens, 3-10m mounting height. Six to eight hours to charge, three to five overcast nights of reserve, no cable anywhere.

Why overseas buyers keep choosing it

• They can defend the number. Panel, pack, lumen and reserve are all stated, so the figure survives a procurement committee.
• It survives a bad install. One body and one bracket tolerate a crew that never read the spec better than a three-box split system.
• Field serviceable. Battery and controller come out through the back plate in minutes, not weeks.
• Heat is designed out. The hollow body moves air across the LED board, so output does not fade by year three.
• We say no when it is wrong. 18000 lumens on a 4m garden pole is a glare complaint, so we quote the 40W instead.

Who builds it

LEADRAY has made outdoor lighting in Shenzhen since 2005: 300-500 staff, 80-90% of output exported, own tooling, die-casting, CNC machining and a lab running aging, IP and temperature cycle tests on every batch. Our solar lines already run on village roads, communities and compounds across Africa, the Middle East and South America.

Send the pole height, road width and the number of overcast days you must cover. You get a configuration and the reasoning behind it, not just a price.
