MyLEDLightingGuide's Series of X-Large Sized Retrofits can replace up to 1500 Watt Metal Halide or High Pressure Sodium 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.

Up to 154 lumens per watt, depending on the model and chosen color temperature. We recommend 5000K as the perfect replacement for Metal Halide. These kits come available with multiple mounting options. Our kits do not come with a socket adapter as this is an unsafe mounting option and is not allowed under the DLC Premium Quality certification.

The patented heat sink design provides advanced cooling which will ultimately extend the life of the product. Compare our retrofit head side by side with a competitive product. Run them both for an hour and touch the heat sink. You will be surprised how much cooler ours is. L70 hours exceed 100,000 hours. Backed by a 10 year head and 5 year driver warranty.

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: reflector of fixture must be removed as part of the installation process of this unit. 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.

Technical Highlights:

  • New patent pending heat sink with side flow cooling technology - the first in its kind for LED Retrofit - provides superior performance and cooling
  • Advanced circuit design
  • Top quality UL PCB board
  • Latest Nichia LED Chipset
  • Intelligent thermal control with auto recovery
  • short circuit / over current / over voltage protection.
  • 154-155 lumens/watt!

  • 1000W HID replacement
  • 1500W HID replacement

  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.
