Pressed on by its security department that was anxious to have better lighting in the 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.
Nestled in the foothills of the Hualapai Mountain range, the award-winning Kingman Regional Medical Center (KRMC) is a community-owned 235-bed healthcare facility located in Kingman, Arizona—the seat of the Mohave County. It is the largest provider of health and wellness services in northwestern Arizona and has been often recognized as one of the nation’s top 100 hospitals in the State of the Nation’s Hospitals report. At 3,500 feet in elevation, the hospital sits in a beautiful high-desert rural community.
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, not to mention 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.
What started as a project to get better-lit images out of the security cameras ended up as a whole package of energy savings as well as security benefits and better lighting for users of the parking lot. Due to the success of the project, Kingman is now looking at other areas within the facility where LED lighting might bring energy savings as well as reduce maintenance labor and time.

LEDtronics® announces another of its energy-saving LED light bulbs: the LED15T4 -SIW-120A T4 tube bulb with an E12 candelabra base and 120A input voltage. The 0.9-Watt consuming LED tube bulb replaces incandescent bulb numbers 15T4, 15T6/CB/130, 15T7/CB/130 and GE 15T7C 13494 up to 15 Watts.
The LED15T4 series boasts more than 23 lumens and a spherical candela of 1.84 while drawing just 0.18mA current. This translates into an efficacy of 23.1 lumens per a watt of energy. It provides a warm-white light in the range 2800K to 3200K and is ideally used in indicator lamps, theater aisle seats, night lights, step lights and decorative lighting. It easily installs in any fixture with an E12 candelabra base.
With the 50,000-hour lifespan of white LEDs, the LEDtronics LED15T4 series lamp offers 50 times the average 1,000-hour rated life of an equivalent filament T4 bulb. With the 94% energy reduction compared to a 15-Watt incandescent bulb, savings from greatly extended life, reduced maintenance costs and major reduction in energy usage quickly return the capital investment expenditure, making the LED bulb as friendly to the environment as it is to the operating budget.
A clear, shatter-resistant polypropylene lens and a Rynite® sleeve protect the LEDs from environmental stress, while the solid-state design renders them impervious to electrical and mechanical shock, vibration, frequent switching and environmental extremes. LED lamps produce almost no heat and do not get hot to the touch. The LED15T4 -SIW-120A T4 tube bulb operates in an ambient operating temperature range of ~-22°F to ~+122°F.
The LEDtronics LED15T4 series bulbs comes with a 3-year limited warranty and is priced $18.53 each; availability is stock to 4-6 weeks for special requirements. Large-quantity discounts are available.
