What about the color rendering index of high pressure sodium lamp?And what are their luminous efficiency?Thank you
The color rendering of ordinary high pressure sodium lamp is CRI 23, the high color sodium lamp is CRI 83; the metal halide lamp varies according to different products and power, and the color rendering CRI is from 65-90.Ordinary sodium lighting efficiency varies from 40LM/W to 150LM/W depending on the product and power
The color index of high pressure sodium lamp is 20-25RaCeramic metal halide lamp 80-95RaQuartz metal halide lamp 65-70RaPlatinum can be better understanding of photoelectric.
The color index of high pressure sodium lamp is 20-30, light effect is 120lm/wGold halide lamp, quartz gold halide lamp, color rendering index 60-85, light effect 80lm/wThe color index of ceramic metal halide lamp is 95, and the luminous efficiency is 110lm/wIn addition, the high color sodium lamp is a special light source. It is seldom used in daily use, and the color rendering index can reach 80-90
