This
retrofit replaced 462-watt HID fixtures with 238-watt, high-output T-5
lamp fixtures including (mirror type) specular reflectors and
electronic ballasts. The change increased illumination in the aisles
from an average of 4 foot candles to 18 foot candles measured at 5 ft.
above the floor.
In this case, the customer saved 224 watts on each of 258 fixtures upgraded.
Business calculations show this change provides annual savings of
$20,380 with an ROI of 24.69% and a payback on electricity savings of
48 months. The job is covered by a 5-year warranty on parts and labor. |
