LED Vertical Freezer Lighting:
More than 50% of the energy consumption in a retail store is dedicated to refrigeration.
Refrigeration lighting represents approximately 12-13% of total electricity costs.
Inefficient fluorescent tubes result not only in higher maintenance and energy consumption, but also generate significant heat which works against your refrigeration compressor unit (estimated at 25% additional costs).

- Kw usage based on a typical Vertical glass door freezer
- Fluorescent -typical F58T8, 58W by 60” tube
- POSiLiGHT solid state LED fixtures
- Assume 13 hours on time/ day X 364 days/ year to calculate Total estimated energy cost savings.
