The NU4RD-LMX LITEOPTICS 4" recessed downlight by ALPHABET, using araya5 LogicModules from Lumenetix, dynamically and precisely tunes light with accuracy, control andnconsistency. White light at 90+ CRI is delivered with a color consistency within a 2-step MacAdamnellipse (SDCM) across a range of 1650K to 8000K. Gradients of saturated colors from 1 to 100%ncan be added to color points within the tuning range. On-board, closed-loop thermal feedbackncompensates each color channel for thermally induced variations in light output due to dimmingnor changes in ambient temperatures. On-board, closed-loop optical feedback measures the lumenndepreciation of each channel and re-balances the color model to ensure color consistency overnthe life of the LED array. Available in 120V, 277V and 347V input options with multiple controlnoptions including 0-10V, Bluetooth, DMX512, Legrand Digital Lighting Management (DLM),nDALI and Lutron EcoSystem.
