Office lighting in Treharris
What we do in Treharris: glare-free LED lighting for desks, meeting rooms and receptions. For office lighting in Treharris we design to about 500 lux on desks, as BS EN 12464-1 suggests, and keep glare off screens by choosing the right optics rather than simply adding more light.

If your Treharris office has window bays, daylight sensors can dim the perimeter row of fittings on bright days without anyone noticing.
Reception areas in Treharris often need a warmer, layered look than the open-plan floor, with downlights or a feature pendant over the desk.
Treharris sits within Mid Glamorgan. We work throughout the CF46, CF45 and CF82 postcode districts and surrounding places, including Gelligaer, Penrhiwceiber and Bargoed.
