Semiconductor Illumination Now

Achieved semiconductor light sources efficiency level allows their using in all traditional application areas 2005: 47 lm/W, 0,15 $/lm 2007: 110 lm/W, 0,03 $/lm

Significant resource and high lighting parameters stability Broad white light tones spectrum – CCT from 2600К to 10000К High Color Rendering Index: CRI = 87…95 Harmful substances absence (mercury, lead etc)

Light sources utilization problem solving Good control

Power saving illumination control creation possibility

Light Sources Working Resource

Semiconductor light source doesn’t fail after 50 – 100 thousand hours working in contrast to traditional lamps. There is only monotonous luminous flux decreasing. Urgent light source replacement after resource finish doesn’t need.
