LIGHTING TECHNIQUES TABLE 1: Average light output in lumens per foot of some typical neon colors; assumes a 15mm tube operated by a 30mA magnetic transformer. Color/phosphor lumen/ft@30mA,15mm Clear glass neon red divide by 300; you get the surface in square feet for each foot of tubing (or multiply the diameter in mm by 0.010472). Now take the lumen-output-perfoot from Result 3 and divide it by the surface in square feet (which you just calculated). That will give you the surface brightness in candela per square foot for the bare tube. Up to now, we considered the pure-neon glass sign, without any channel letter or sign box. Add those factors, and things get complicated. The most simple situation is the classic, open-face, polished, stainless-steel channel letter (Photo 1). Each surface reflects the light at approximately 90% of the incident intensity. Roughly, we can say the light from the tube’s front-half circumference isn’t reflected, but seen directly, and the other half is reflected at 90% of its intensity. 175 Clear glass blue (Argon + Mercury) 60 Standard sign green (Zinc orthosilicate) 252 Standard sign blue (Tungstate) 99 Coral pink (Yttrium Vanadate) 136 Turquoise rare earth (RE) 178 6500 White halophosphate 158 6500 White RE triphosphor 210 4500 White halophosphate 165 4500 White RE triphosphor 194 Clear gold (double coat) 168 Noviol yellow (color glass, RE powder) 106 Emerald green (color glass, RE powder) 73 Ruby red argon (color glass) 28 Note: These numbers are averaged values from the following manufacturers: EGL, FMS Brillite, TecnoLux, Voltarc (Lightsources Inc.) - Though not all manufacturers have listed all colors, or have different phosphor compositions, actual values may differ from these values.
