MyLEDLightingGuide’s 350W LED Retrofit Kit is designed as a 1500 Watt LED Replacements for Metal Halide in your existing fixture with a simple and easy to perform retrofit process. Our X-Large Series Retrofits are extremely energy efficient and are DLC Premium Qualified meaning it meets higher lumen efficiency standards and outperforms those products that are only DLC Standard Qualified. These kits are 20-30% brighter than DLC Standard Kits. 

Our X-Large Series LED Bulb and Ballast Replacement Kits are perfect for a variety of fixtures including

  • Parking Lot lights and Area Lights
  • Flood Lights
  • Stadium Lights
  • High Mast Lights


Please note: the reflector inside the fixture must be removed as part of the installation process of this product. The reflector is not needed because LED is directional light and there is no light to reflect. Removing the reflector also increases the available cooling area inside the fixture.

Easy Installation Steps

  1. Remove bulb, ballast, reflector and socket from existing fixture.
  2. Install retrofit mount arm system using the mounting holes of the removed socket
  3. Slide the retrofit head onto the mounting arm, and attach the safety wire
  4. Install the driver in the space where the ballast was installed.
  5. Connect the black and red wires of the driver to the black and red wires of the retrofit head.
  6. Connect the input wires to the power cord coming into the fixture.
