The zoom‐able spot lighting fixture using WRGB LED is proposed. The fixture is divided into 2 parts, WRGB LED light source and the projection zoom lenses. The WRGB LED position arrangement is optimized to product more uniform colorful output and decrease the loading of the diffuser film. with the projection zoom lenses, the fixture have the divergent angle from 10 to 30 degree and 3000 lumens output which is useful in plaza or spot lighting.
