Osram Ostar Stage LEDs from Osram Opto Semiconductors offer high luminance of 48 million candelas per square meter (Mcd/m²) and tunable color tones from cold white to warm white. Combined with their extremely low-profile design and glass cover with its anti-reflective coating, they provide the basis for compact spotlights with an extremely narrow beam. This LED is ideal for use in moving head spotlights on stage, for booth lighting at trade fairs and for architectural lighting.   The special feature of the new LED is its tunable white light color. Two warm-white and two cold-white chips, arranged diagonally in the package, not only enable colors to be mixed perfectly at component level but also allow all white tones between color temperatures of 2700 Kelvin (K) (warm white) and 10,000 K (cold white) to be produced with appropriate control. The LED achieves a high color rendering index of 94 for warm white and 74 for cold white.
