TDK-Lambda is one of the world's leading power supply manufacturers and we use them in every American LED Technology sign! We test the limits of all things that go into making one of our signs, the final result is a high performing display that will shine in any sort of situation.


Our customers expect a reliable LED display, and that's what we deliver!


With these two videos (Day 01 and Day 02) we tried our best to overheat and damage our sign! Unfortunately even with the inside parts reaching over 190 degrees, everything still worked perfectly. On day 2 we brought in a better camera to take readings with. We also added a stronger heater. Everything was so hot that we had to use welding gloves for protection.
