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).

Comparative energy consumption analysis:

VERTICAL FREEZER (NUMBER OF DOORS) 3 4 5
Fluorescent (in Watts) 232 290 348
POSILIGHT (in Watts) 60 80 100
Power savings (in Kw) 172 210 248
Relative power savings % 74.13% 72.41% 71.26%
Estimated annual energy savings in KwH 813 994 1173
Estimated annual energy savings at 25% 275 343 412
Total annual cost savings in KwH 1088 1337 1585
Estimated annual cost savings @$0.10/KwH $108.80 $133.70 $158.50

 

Analysis parameters:

  • 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.
