To have better lighting in Arizona hospital’s parking lot for the security cameras to operate more efficiently, the Facilities Maintenance Department of Kingman Regional Medical Center approached Howard Industrial Sales in nearby Chandler to initiate energy savings comparisons and a lighting upgrade proposal in order to increase the light output in its vast parking lot.

The medical center was using 250-watt HPS lamps in 88 fixtures throughout the campus, running on voltage ranges from 120VAC to 277VAC. The poles are mostly around 16-20 feet high, with some in the 24'-26' range; they are spaced 40-60 feet apart in the parking lot.

When Howard Industrial Sales made a demonstration of the 88-watt LEDtronics SLL003P-30X2W-XPW-005 LED luminaire, the chairman of the board, managers and other executives were all impressed by the light output and the resulting detail clarity in the security cameras, and the energy savings of 202 watts per fixture.

The proposed upgrade to LED lighting also coincided with the KRMC embracing the green movement in recent months and undertaking a leadership position in environmentally friendly solutions in their community.

An initial order to replace the 88 HPS lamps was shipped within a few months, followed by another shipment to bring the total to 104 LED lamps. The shoebox-style LED luminaires use over 60% less energy than the conventional HPS units that were being used, and require much less maintenance in the way of bulb and ballast replacement.

The LEDtronics LED parking-lot lights are provided with a 5-year warranty and will provide useful light with no more than 30% light degradation at 50,000 hours of operation. This results in an estimated savings slightly in excess of $100,000 during that time frame.
