• T8 fluorescent lamps have the following metrics and issues:

p g

– 83~88lm/w typical design lamp efficacy at 25°C ambient temperature – 70~85Ra typical CRI, lower efficacy at higher CRI figures 20K 25K hour 50% (L50) survival life lower when cycling more often – 20K~25K hour 50% (L50) survival life, lower when cycling more often – Suffer fromchromatic shift over time, turning pinkish red to purple – Source of mercury contamination from low recycling levels in the US – Substantial lumen loss from LDD (Luminaire Dirt Depreciation) within months due to dust accumulation above lamps – Lower lux levels due to diffuse light spread, lamps also physically block substantial portions of the light reflected off the reflector
