The Lina LED slide has a straightforward design. Its bright light emits a white color. It is eco-energetic and sustainable with an LED lifetime of 50,000 hours minimum (equivalent to 20 years of intensive use without maintenance) and has a 5 year guarantee. Its 17 watts power 12 LEDs which are housed in an aluminum anodized with a small footprint -- 20 mm in diameter and 400 mm in length. A transparent cover made of polycarbonate which allows optimal distribution of light and excellent protection against dust or splash (IP53) protects the LEDs. The LEDs are mounted on a printed circuit and are efficiently cooled by the aluminum profile which then contributes to its overall effectivity. Other features include : - Kelvin : 6000° - Color Rendering Index (IRC) : 95 - Cable Length : 3 meters - Insulation : Classe II - At 50 cm : 2500 lux; At 90 cm : 900 lux
