Municipal and private projects keep buying all-in-one solar lights, and the category rewards buyers who specify tightly, because nameplate wattage is routinely overstated.
Why it is moving
Unreliable grid supply plus falling panel and battery prices make solar lighting cheaper than cabling new mains runs, especially for compounds, car parks and roadside projects.
What to verify before the deposit
Lighting is the category where paper specs and measured performance diverge the most.
- Measured lumen output and LM-80 data, not the wattage printed on the housing
- Actual battery capacity in Wh, verified by weight and cell markings
- IP rating tested on the finished fixture, including the gasket and cable gland
- Warranty terms in writing, with a named spare-parts allowance per shipment
Sourcing notes
We photograph the label of every carton during inspection and cross-check it against the purchase order, because relabelled lower-wattage stock is the most common substitution in this category.
