The only silly question is the one we don’t ask… or, something like that. Well, here are some answers to the questions we hear most often. If you don’t see the answer you need, please don’t hesitate to contact us.
Where are your LEDs made?
Most of our LED modules are made at our factory (Principal Tech.) in Taiwan, with additional assembly at our plant in Texas. PLED also has contract manufacturing plants in Shenzhen and Shanghai, China.
How can I buy your product?
Principal LED has over 75 distribution locations throughout the USA, Canada, and South America. Navigate to Where to Buy for a list by state and specific location.
How do you bin your LEDs?
Our Fusion DM LEDs are binned ourselves at the module level using 100% automated test equipment. SMD parts that we source come from a single bin and then are sub-binned to further increase uniformity.
How long do your LEDs last?
In addition to accelerated life and LM-79 and LM-80 test data, we track all returns. Principal LED sign modules has a failure rate of less than 0.01%. That is why we offer extended labor warranty on our entire line of outdoor LEDs for signs.
