T5HO High Bays in Warehouse Applications
Light level recommendations for warehouses or manufacturing plants range from 10 foot candles (fc) for inactive areas to over 50 fc for detail loading areas.
Traditional 400 W Metal Halide high bays consume a total of 454 Watts of power - 400 Watts for the lamp and an additional 54 watts of ballast power. By comparison, a 4-lamp T5HO fixture consumes only 228 Watts of power while a 6-lamp fixture consumes 342 Watts. This lower energy consumption allows for a reduction in total lighting system consumption and therefore a lower electric bill. To provide concrete numbers, let's work with an example and assume we're investigating replacing 30 existing 400W MH fixtures with T5HO fluorescent fixtures. The table below summarizes the costs associated with lighting this warehouse assuming a cost of $0.10 per kWh and an annual usage of 4,368 hours.
