GFS BOOTH BLOG — Proper paint booth lighting plays a crucial role in achieving a quality paint job. There are many factors that go into creating a well-lit environment, including fixture quality, fixture location and type of light tube. The following are a few things to consider when it comes to paint booth lighting.

1. T8 Energy-Efficient Light Tubes

T8 light tubes are much more energy-efficient and cost-effective than its predecessor, T12, which are no longer in production. If you have an old booth with T12 light fixtures, be sure to upgrade your booth to T8 fixtures, as you will no longer be able to purchase replacement T12 lights.

2. Color-Corrected Tubes

For many paint jobs, color matching is critical. In order to accurately color match, the lighting in the paint booth should match outdoor lighting. This is accomplished by using color-corrected light tubes.

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.
