LED – Light Emitting Diode, High Bay Fixtures
- Newest technology for illuminating factories, warehouses and industrial spaces
- Provides 35-70% savings in lighting energy costs (depending on existing fixtures)
- Provides bright, high quality light levels
- The brighter light helps to improve productivity & employee morale
- LED’s typically last 70,000-100,000 hours
- Accommodates occupancy sensors
- Runs cooler, less taxing on your A/C vs. metal halide fixtures
- Lower maintenance costs
HIF – High-Intensity Fluorescent T5 High Bay Fixtures:
- T5’s are still the #1 seller when replacing HID (metal halide) fixtures
- Provides 50-70% savings in lighting energy costs vs. HID fixtures
- Provides bright, high quality light levels
- The brighter light helps to improve productivity & employee morale
- Average rated lamp life of 35,000 hours
- Accommodates occupancy sensors
- Runs cooler, less taxing on your A/C vs. metal halide fixtures
- Lower maintenance costs
*HID – High Intensity Discharge (Old, Less Efficient Lighting):
- Typically Metal Halide 400 watt fixtures which draw 458 watts
- More expensive to operate by 50%
- Metal halide fixtures depreciate in lumen output dramatically over time.
- Light is not as white
- Average rated lamp life of 20,000 hours
- Runs as hot as 300-400 degrees, taxing your A/C
- Not air conditioned, they still make for a hotter work environment
*HID Lights would include all three types: Metal Halide, High Pressure Sodium (yellow) and Mercury Vapor lights.
Color Temperature
Color temperature is conventionally stated as Kelvin temperature, having the unit symbol K. Color temperatures over 5,000K are called cool colors (bluish white), while lower color temperatures (2,700–3,000K) are called warm colors (yellowish white through red).
Offices would typically use 3500K or 4100K while a warehouse or manufacturing plant is better served with brighter, 5000K (whiter white).
Foot Candles
The unit of measurement indicating how much light is reaching the surface, 30 inches above the floor.
CRI
Color rendering index is the color appearance of an object when illuminated. Scales ranges from 0 to 100. The higher the CRI number, the less distortion of the object’s color, providing a more accurate rendering of the objects actual color.
