features Lamps available in 40, 60, 80, 120.150, 200 and 400 watts controller 12 VDC, 85-277 VAC. Long average life of 88.000 to 100.000 hours, about 20 years old with a use of 4,000 hours per year Light efficiency. 70-80lm / W High Color Rendering Index (CRI) 90%, high resolution and natural color quick Start Advantage especially with hot lamp start, taking an obvious advantage against vapor lamps high pressure sodium and metal halide. High Power Factor > = 0.95 High frequency operation Soft light effect, flicker, protects the eye, makes colors look more natural, like sunlight. Low luminance decay The luminance is maintained at 70% after 60,000 hours, which ensures stable light output in the life of a lamp. Wide range of color temperatures to 6500K depending on the application (5000K STANDARD) Constant Power The power varies less than 3% of the input voltage variation of + / -20%, to ensure a constant light source. Works at low temperatures You can work at -20 ° C Low harmonic content THD
