Office lighting in Treflys
Glare-free LED lighting for desks, meeting rooms and receptions. Reception areas in Treflys often need a warmer, layered look than the open-plan floor, with downlights or a feature pendant over the desk.

Local office lighting in Treflys
For office lighting in Treflys 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.
We usually phase office work in Treflys over evenings, one zone at a time, so nobody loses a desk while the ceiling is opened up.
We cover the whole of Treflys, including the LD5 and LD4 postcode districts, and nearby places such as Llangamarch, Duhonw and Llandovery.
