What are Mogul Base LED Bulbs?
Mogul base LED bulbs are large-format LED replacement bulbs featuring a 39mm (1.5-inch) diameter screw base, known as E39 or EX39. These professional-grade lamps are the industry standard for high-wattage applications, allowing for a seamless HID retrofit of metal halide and high-pressure sodium systems. An E39 LED bulb or EX39 LED bulb is engineered to handle the high thermal demands of industrial environments, delivering high-lumen output for warehouses, factories, and outdoor site lighting.
HID vs. LED: Mogul Base Efficiency Comparison
Upgrading to mogul base LED bulbs provides immediate energy reduction across all industrial categories. Replacing a traditional system with a mogul base LED corn bulb or specialized retrofit can reduce power consumption by over 75%.
| Traditional HID Source | Traditional System Wattage | LED System Wattage | Energy Savings |
| 175W Metal Halide | 210W | 45W | 79% |
| 250W Metal Halide | 300W | 63W-75W | 75% |
| 400W Metal Halide | 480W | 100W-120W | 75% |
| 1000W Metal Halide | 1200W | 300W-450W | 63% |
E39 vs. EX39: Understanding the Difference
When choosing a mogul base LED bulb, it is critical to select the correct base type for your fixture safety requirements:
- E39 (Standard Mogul): The most common base for commercial fixtures. It is typically designed for use in fully enclosed fixtures.
- EX39 (Extended Mogul): Features a slightly longer center tip. EX39 LED bulbs are "open-rated," meaning they are protected by a shield and can be safely used in both open and enclosed fixtures. EX39 bulbs are backward compatible and will fit into standard E39 sockets.
High-Performance Industrial Features of Mogul Base LED Bulbs
- Field-Selectable Technology: Many E39 LED bulb models include switches to toggle between color temperatures (3000K/4000K/5000K) and wattage levels.
- Smart Port Connectivity: Integrated ports support plug-and-play microwave motion sensors and photocells to maximize automated energy savings.
- Advanced Surge Protection: Most industrial-grade lamps include 4kV to 6kV surge suppression to protect internal drivers from voltage spikes.
- Active Cooling Design: Performance Class models utilize integrated heat sinks and advanced airflow to maintain low operating temperatures in high-ambient environments.
