While colored LED’s offer superior color-fastness, they also have a very electronic appearance, and are what you would visually associate with other LED based Christmas lights. Additionally, the very narrow color spectrum emitted from colored LED’s casts a uniquely “electronic” glow. Our JEWELTONE™ bulbs incorporate our warm-white Tru-Tone™ filament, and offer beautifully saturated color that more accurately replicates incandescent, casting a bright, warm glow.
