Quality of Light

See how the simple change of a light bulb can give your business a dramatic new look.

The color rendering of a light source describes that source's ability to accurately render the colors of perceived objects - people and things. As a general rule, the higher a light source's Color Rendering Index (CRI) number, the better the lamp will make things appear.

SP lamps have a CRI of 70+ making them better color rendering light sources than older standard fluorescent lamps. SPX lamps have a CRI of 80+ even better than SP lamps, an even higher color rendering with the same high efficiency. A second consideration in light source selection is the degree of visual "coolness" or "warmth" of the light source.

GE SP30 and SPX30 lamps produce a warm appearance slightly enhancing reds and yellows. SP35 and SPX35 lamps produce a balanced tone, midway between warm and cool. SP41 and SPX41 lamps are cooler in tone, slightly biased toward blues and greens. SPX50 is a very cool, high color rendering light source designed to simulate natural outdoor daylight at high efficiency. SP65 and SPX65 lamps also provide very cool light similar to the north sky and are considered an ideal substitute for daylight color lamps.
