180 poles · 6,000 lm · 18 m spacing
A 180-pole retrofit that avoided 2.4 km of trenching
A leased logistics yard could not justify trenching for lighting, so the lighting had to arrive with its own power.

The site is leased for nine years, which killed the capital case for a trenched lighting circuit. Solar poles moved the cost into a single line item with a five-year payback.
We modelled the yard in DIALux at 8 m mounting height and 18 m spacing, targeting 20 lux average with 0.35 uniformity. The chosen fixture holds 6,000 lm and dims to 30% between vehicle movements.
Commissioning took nine days for 180 poles, including the time profile and motion threshold for each. Winter autonomy was verified in the first February: the lowest pole returned 3.4 nights of reserve.
