Light Efficient Design LED-8000M345-FW-MV 300/360/450W EX39 LED Corn Cob Retrofit: 3-CCT, 208–347V AC
A high-output EX39 mogul-base LED post-top retrofit lamp with 300W, 360W, and 450W settings, 3000K/4000K/5000K color selection, 50,100–73,300 lumens, and 208–347V AC operation.
High-Output LED Retrofit for medium-voltage commercial and industrial systems
The Light Efficient Design LED-8000M345-FW-MV converts compatible post-top and area-light fixtures to high-output LED performance. Three selectable wattages and three selectable color temperatures let installers configure the lamp for parking lots, roadways, pathways, and security-lighting applications.
Output ranges from 50,100 to 73,300 lumens, with a 360-degree beam designed to use the existing fixture's optical system. The active cooling fan manages heat, while 6kA surge protection adds protection against electrical transients in demanding outdoor-lighting circuits.
⚙️ 300W / 360W / 450W
Select output with side-mounted switches; the factory default is 360W.
🎚️ 3000K / 4000K / 5000K
Set warm, neutral, or cool white light; the factory default is 4000K.
🌬️ Active Cooling Fan
Integrated active cooling supports thermal management at high operating wattages.
⚡ 6kA Surge Protection
Built-in surge protection helps protect the retrofit lamp on outdoor electrical systems.
⚠️ Ballast Bypass and Voltage Verification Required
The existing ballast must be bypassed. Confirm that the supply is within the 208–347V AC input range before installation; do not substitute this version on an incompatible circuit.
📋 Post-Top, Area, Roadway, and Security Lighting
The lamp can be mounted base up, base down, or horizontally. It is suitable for compatible enclosed fixtures and damp locations, providing a configurable LED replacement for high-wattage legacy lamps in large outdoor fixtures.
Key Features & Benefits
- Replaces multiple wattages: The selectable design can replace legacy lamps rated up to 1,000 watts.
- Adjustable output: Changing the wattage provides approximately 50% to 70% output adjustment without a separate dimmer.
- Field-selectable light color: Three CCT settings help coordinate lighting across roadways, parking areas, and security zones.
- Orientation flexibility: Base-up, base-down, and horizontal mounting support a wide range of existing fixture designs.
- Outdoor operating range: Operation from -40°F to 122°F supports demanding seasonal conditions.
- Longer maintenance cycle: Up to 50,000 hours of rated life reduces service frequency in elevated fixtures.
