180W Solar Street Light Aluminium 24Ah LiFePO4

For larger sites that still want a single self-contained fitting, this 180W aluminium solar street light carries 324 Bridgelux 5730 LEDs and is specified on industrial yards, campuses, transport depots and long estate roads.

The LED array runs at 6000K to 6500K with a stated 160 lm/W. A 10V 28W polycrystalline panel charges the LiFePO4 6.4V 24Ah battery, and the manufacturer's figures are 6 to 8 hours of charging against 20 to 24 hours of discharge, so the pack is sized to hold reserve past a single night. Anyone comparing this against the 120W model should weigh the extra 6Ah of storage and 6W of panel against the larger array it has to feed. Construction is aluminium, measuring 901 x 220 x 118mm.

Mount at 8 to 10 metres, which needs a street-grade pole and bracket. Sensible applications include weighbridges, container yards, hospital grounds and sports areas, often several units in a line rather than one in the middle. Output through the night follows siting and season, so plan for unshaded panel positions. The manufacturer states a 3 year warranty.
