Our LED Parking lot lights are a replacement for your typical HID / HPS lights for example, we can replace a 1000 watt HID / HPS parking lot fixture with a 240 watt fixture instead. With a 400 watt HID / HPS lights you can use a 120 watt LED light. Our lights are designed to be maintainable after the warranty. The ability to repair the fixture after the warranty makes switching to LED lights more affordable. With most other LED Parking lot lights you have to return the fixture to the manufacture to get it fixed.
