Tru-Tone LED Christmas Bulbs have a vintage appearance but are the result of modern electronic developments. The stated average lifespan of our bulbs is 20,000 hours, determined by strict lab testing by the LED component manufacturer.
Our own outdoor testing in northern Michigan surpassed 25,000 hours without failures. None of these lifespan statements are indicative of a warranty period.
The most vulnerable components of our bulbs are the glass enclosure and colored coatings, which may see damage or wear before the LED filament fails. While safe to use outdoors, exposure to the elements may increase the likelihood of fading, early wear or failure.
See our Product Guide for more information about storage, outdoor use and fading.
