Channel Letter Lighting Choices

There are different ways that you can light up your channel letter sign:  neon, SpectraLites internal LEDs, SolarBrite internal LEDs, and LetterLites external LEDs.

Click on the "Neon", the "SpectraLites and LED" and the "LetterLites LED" tabs to the left to learn about these lighting options.

There are two important indexes for judging the importance of various lamps in illuminating your sign: Color Rendering Index (CRI) and the light’s color, expressed as degrees Kelvin (K).

In degrees Kelvin a lower number is a more “yellow/red” light, a higher number is a more “blue” light.

Interestingly, the color of “daylight” varies from the equator to the poles.  But it is generally accepted as about 6000K with a CRI of 100.

A CRI of 100 is perfectly matching the sun’s effect on colors.

In white neon the old standard has been that 6500K neon is best for lighting a sign face.  It has a CRI of 65.  The tri-phosphor “rare earth” neon Dallas Signs Manufacturing uses to illuminate digital graphics, translucent paint, translucent vinyl, and color transparencies has a CRI of almost 100.

Unless you work for a very major corporation and have been paid to study this issue this information has not been readily available until now.

NBC LOGO WITH 2 DIFFERENT LIGHT SOURCESThanks to digital photography we are now able to show you what we are talking about without asking each potential customer to visit our lighting laboratory.

The left side of the picture is a sign lighted by Daylight HO fluorescent lamps, the right side with CW HO lamps.  A thin black line has been placed where the two pictures are spliced together.

Daylight HO lamps are 6000K with a CRI of 65.  CW HO lamps are 4500K with a CRI of 50.

Fluorescent lamps are actually just large pieces of neon!

Our simple goal is to get a potential customer to notice your sign first; rather than look at someone else’s sign and never notice yours.
