Warehouse lighting in Treflys
LED high bays and aisle lighting for warehouses and distribution sites. Loading bays in Treflys need good light at the dock edge and inside trailers. We often add dedicated dock lights alongside the high bay upgrade.

Local warehouse lighting in Treflys
Many Treflys sites run two or three shifts, so lighting hours are high and LED payback is quick, often inside three years.
Aisle-by-aisle presence sensing works well in Treflys warehouses where some aisles are only visited a few times an hour.
We cover the whole of Treflys, including the LD5 and LD4 postcode districts, and nearby places such as Llangamarch, Duhonw and Llandovery.
