SLIMLED™ Dim to warm LED fixture. LEDs can be used in virtually any lighting application with greatly improved colour quality and warm CCTs at high CRI levels. When fixtures are being used on a dimmer, as the light level drops, todays’ LEDs maintain the same colour temperature that they exhibit at full power. Incandescent and halogen lamps dim to a warmer CCT at lower levels. Dim-to-warm technology is now available in LED lighting fixtures they can deliver 3000°K CCT light at full power yet smoothly reduce the CCT to the 2000°K range at the lowest dimming light levels.
