Langland House an office redevelopment which required an LED system.

PIR sensors were built into the PREMLED 600mm x 600mm recessed luminaire. The PREMLED was spaced at 3.0m x 2.4m, whilst still providing even light distribution and reaching 400lux on the desks.

The PIR sensors were set at 20 minutes allowing the office lights to remain on during normal working hours but off at times when the employees were arriving or leaving for the day.

The same luminaires were used in the rest of the areas.
