COB Warm Dim matches the dimming curve of halogen lighting, getting warmer as brightness decreases. The innovative LED design enables high performance and efficacy without the cost and complexity of alternatives. It works with standard 0-10V dimmable drivers and eliminates the need for complex controls.Our chip has a 10 mm light emitting surface, with dim to warm from 3000-1800K. COB Warm Dim maintains 90+ CRI throughout the dimming range. We use 3-Step MacAdam binning to ensure color consistency.FEATURES 5-Year Warranty Chip-on-Board LED Mimics Halogen Dimming on Any Compatible Driver Works With Standard 0-10V, ELV, and TRIAC Drivers CCT Range: 3000 K - 1800 K CRI: 90+ Throughout Entire Dimming Range 3-Step MacAdam Binning High Efficacy: 98 lm/WGENERAL SPECIFICATIONS Forward Voltage: 36 V Max Voltage: 36.5 V Power: 12.5 W Nominal Current: 350 mA Max Current: 385 mA Luminous Flux: 1220 lm (nominal) Light Emitting Surface: 10 mm Diameter Board Size: 12 mm x 15 mm L70: 45,000 Hours (Calculated, 105 °C, 350 mA)
