Residential Area Benefits from 2D Ledison Lights

Project Description

The residential area of Belgrade Plaza has 64 modern apartments. The communal areas had 350 circular light fittings installed using traditional 28W 2d's and twin 18 PL lamps. The existing housings were kept but use the Ledison 2D Lamp. Ledison supplied and installed 12watt 2D LED lamps with the integrated microwave sensor and emergency pack.

To comply with building regulations, the LED lights on the stairwells and in front of the elevators are switched on 24/7. Only the lights in the corridors are controlled by microwave sensors.

Electrical Savings

The electricity usage for lighting was down to 85% after the installation of the 2D LED. This impressive amount of energy savings was achieved due to the microwave sensors and the ultra-efficient LED lamps. The sensor detects movement in a similar way to a PIR sensor and will activate the light for an adjustable preset duration from 6 seconds to 30 minutes.

Payback

The return of investment is calculated to only 9months, while the actual energy savings have reached the staggering amount of 85%. The corridor lights are automatically switched on only when a resident walks there. The LED lights will remain on for a present period of 2 minutes.
