It all starts with the light, and not all LED lights are the same. Unlike traditional light bulbs where the science behind the light bulb has not changed for decades, the actual LED diode is similar to a computer chip where efficiency and performance continuously improve. Comparing two LED lights because they have the same wattage would be like comparing two computers because they look similar.
Signal Power is the only light tower manufacturer in the world to actually design and build its own lighting. The LED lights manufactured and tested by Signal Power are the most advanced and effiecient LEDs in the world and are designed around DOT, FAA and US Military open air lighting standards.
