Next Generation for high lumen density, white COB arrays featuring the latest enhancement to improve maximum operating temperature, Robusto technology. High lumen density parts are used in narrow beam applications where Center Beam Candle Power (CBCP) is the key metric.
While this depends on the specific beam angle and power level, the high lumen density parts typically deliver two times or greater lumen density than standard parts. Higher temperature operation means more luminaire design flexibility and lower potential cost with, for example, smaller, lighter heat sinks.
These Generation 4 high lumen density parts provide stable lumen output and color points with temperatures as high as Tc = 120⁰C. Robusto technology has the ability toenable higher drive currents while still delivering exceptional lumen maintenance (L90>55k hrs.) and remarkably stable color points. This line of COBs has outstanding color quality, high lumen intensity, and the industry’s best flux and color stability over their operating life all which make them the preferred solution for narrow beam, high CBCP applications in retail and shop lighting, hospitality lighting, architectural and specialty lighting.
