3. Color Rendering Index (CRI)
The Color Rendering Index (CRI) measures lighting quality, on a scale of 0 to 100. The closer the number is to 100, the truer the color of light is. Higher CRI rated lamps should be used when quality or color matching is important.
One thing to keep in mind though is that higher CRI rated lamps tend to be less energy efficient than lamps with lower CRI rating.
4. Foot Candles
The brightness of a booth can be measured in foot-candles. A candle is the intensity of light in a given direction. An ordinary wax candle has the luminous intensity of one-foot candle. The industry standard for a paint booth is 100 to 150 foot-candles at a 3-foot height. If a different foot-candle is desired, light quantity, placement and size should be adjusted.
5. Clear Tempered Lens
A clear tempered lens on the light fixture allows for clearer, more accurate lighting. Tempered glass is 4 to 5 times stronger than regular glass of equal size and thickness. It’s also much clearer than wire reinforced glass, which was previous used in GFS paint booths.
6. Energy-Efficient Dual Ballasts
An energy-saving feature, 6-tube dual ballast fixtures offer two levels of lighting. When less light is needed, such as during prep operations, you can save on energy costs by using half of the lights (3 tubes). Full lighting can be easily restored for painting operations and detail work.
7. Inside-Accessible Fixtures
Depending on your shop and booth location, it may be difficult to get at the sides or top of the booth to replace light bulbs. Inside-accessible light fixtures swing open to the inside of the booth, allowing for much easier light replacement.
8. Class I Division II Electrical 3rd Party Listing
We cannot express enough the importance of code compliance when purchasing and installing a paint booth. In addition to the booth as a whole, certain booth components must comply with national, state and local regulations. When it comes to lighting, regulatory agencies require that booth light fixtures be approved for Class I, Division II, Groups A-D.
