MyLEDLightingGuide's 280 Watt LED Retrofit Kit can replace up to 1000 Watt Metal Halide or High Pressure Sodium in your existing fixture with a simple and easy to perform retrofit process. Our 280 Watt LED Retrofit Kit is extremely energy efficient and is DLC Premium Qualified meaning it meets higher lumen efficiency standards and outperforms those retrofit kits 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 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. Enjoy your energy savings with MyLEDLightingGuide's 280W 43,120 lumens LED Retrofit Kit, perfect for pole mounted, high bay, street light or parking lot applications.

Our LED Retrofit Kits are perfect for a variety of fixtures including:

  • Cobra Head and Street Lights
  • Parking Lot lights and Area Lights
  • Flood Lights
  • Wall Packs
  • Low Bays, High Bays, Canopies and Garage Lights


Please note: reflector of fixture must be removed as part of the installation process of this retrofit kit. 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 retrofits - 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.
  • 280 Watts 43,120 lumens
  • 154 lumens/watt - most efficient 350 watt retrofit kit on the market today!



  • Our 280 Watt LED Retro Kit wins in life rating, wattage savings, payback, CRI, and the ability to retrofit in 99% of existing Metal Halide and High Pressure Sodium fixtures.
