3. Current Condition Description
Current lighting original to the building (2003)
Current lighting is metal halide, which even in good condition is yellowish in color and relatively dim compared to white light
Areas of particular concern are the front faculty parking lot and the student parking lot
Due to monetary constraints, we will do the project in phases in order to keep per-year costs to a minimum
We will plan into future renovation budgets a lighting upgrade for the north and west parking lots (near tennis court and cafeteria)

5. Comparison of Metal Halide and LED
MORE UNIFORM ILLUMINATION WITH LED
LESS SHADOWS WITH LED

6. Proposed Project Scope and Cost
Purchase 32 LED pole lights from Graybar using US Communities pricing ($17,620.00)
HCS Electrical Department mounts lights using existing personnel
The only additional equipment needed will be a rented boom lift (approximately $2,500 for a week)
Total cost of project will be about $20,000
Order-ship time on the lights will be approximately six weeks
No new poles required
Most poles will continue to have one light, replacing metal halide with LED, one for one
Center poles (6) will have one additional LED light mounted on them to increase coverage in the most trafficked area
Each light has a 5-year warranty
