Most warehouses currently use Metal Halides, High Pressure Sodium (Orange light) or fluorescent T-Bay lighting technologies in the warehouse. The problems with these legacy lighting technologies are:
Green Power will undertake an audit of the existing lighting and prepare a light design to replace the energy inefficient legacy technologies with appropriate LED lighting technology in a way that is financially feasible and environmentally responsible. Also, light levels are generally improved as a result the upgrade.

The lumen maintenance of the current and LED lighting technologies is as follows:
Comparison of Metal Halide and LED lighting is as follows:
|Initial lumen output*||27,000||15,960|
|Light Output Ratio||65%||100%|
|System Lumen Output||17,550||15,960|
|Energy saving compared to Metal Halide||64%|
Comparison of fluorescent T-Bay and LED lighting is as follows:
|T-Bay (HO T5)||LED|
|Single Lamp wattage||80||120|
|Initial lumen output*||24,600||15,960|
|Light Output Ratio||75%||100%|
|System Lumen Output||18,450||15,960|
|Energy saving compared to T-Bay (HO T5)||64%|
