Hillcrest assisted living in Boise Idaho had over 800 incandescent light bulbs (both interior and exterior). Bright Ideas Lighting changed out all incandescent lights at the facility to screw in 11 watt LEDs.
Going from the incandescent lights to LEDs reduced energy about 80%, while also increasing the bulb life approximately 10 times, and slightly increasing light levels.
The dining area for the residents had 175 watt mercury vapor lights, which were changed out to new 32 watt LED fixtures. This both increased light levels and light quality.
In picture below the old mercury vapor lights are on the left and new LED fixtures are on the right.
For the exterior lighting we changed out all 115 exterior incandescent lights to 11 watt LEDs. The canopy lights were changed out from a 100 watt R40 mercury vapor light (not even made anymore) to LED par lights. The parking lot lights were changed from 250 watt metal halide to 45 watt LEDs.
Energy savings for this project will be over 200,000 kwh per year.
We used the Idaho Power easy upgrade project for this and the incentives paid for approximately 90% of total cost. Energy savings will pay for project in approximately 3 months.
