GTI Graphiclite D50 and CMlite D65 fluorescent lamps are custom made to rigid specifications for optimum standards compliance and re-creation of CIE illuminants. The precise spectral characteristics and lumen output are subject to an exhaustive quality control process to assure that each lamp provides true full-spectrum, color balanced illumination and extremely accurate color rendition.
Graphic imaging applications (ISO-3664) specify the use of D50 daylight while color and appearance applications (ASTM 1729, SAE J361, BS-950 Part 2, AATCC Procedure #9) specify the use of D65.

Note: GTI Color Viewing Lamps are shipped in standard package sizes of 6 and 30 for T12 lamps, or 8 and 30 for T8 lamps (24 for 60" T8 lamps). The price per lamp is slightly higher when you order lamp kits that have less than the standard lamp quantity.
