TR Bulb refines lighting technology, going from a cozy glow for entertaining to stronger light for reading. Fashioned from opal glass in matte finish or a Dim-To-Warm glossy version, the aluminum core structure draws heat away from the LED, keeping the bulb at optimum temperature. Uniquely, the DTW variant switches from a warm candle-like ambience to a cooler brilliance for more generous, brighter illumination.
