LED lighting upgrades in Welwyn
Swap fluorescent, halogen and metal halide fittings for efficient LED. Most Welwyn businesses we survey still have a mix of T8 battens, 600×600 fluorescent panels and the odd halogen downlight. Replacing them with complete LED luminaires usually cuts lighting energy by a third to a half.
Local LED lighting upgrades in Welwyn
Where ceilings in Welwyn offices are being replaced anyway, we plan the new LED layout to BS EN 12464-1 rather than simply copying the old positions.
Old tubes are hazardous waste. Our teams working in Welwyn bag and recycle them through an authorised route and give you the paperwork.
We cover the whole of Welwyn, including the AL6, AL8 and SG3 postcode districts, and nearby places such as Welwyn Garden City, Knebworth and Hatfield.
