PAR38 LED bulbs are designed for high-intensity illumination in both demanding indoor environments and rugged outdoor applications. As the largest of the parabolic reflector series, these bulbs provide a powerful, concentrated beam that is ideal for high-ceiling recessed cans, warehouse lighting, and outdoor flood fixtures. By upgrading to LED, you can achieve up to 85% energy savings while benefiting from a durable housing that withstands frequent use and varying environmental conditions.
Our collection of PAR38 LED replacements features a wide range of color temperatures and lumen outputs to suit any security or architectural need. Many of these lamps are UL-rated for wet locations, ensuring reliable performance in open-air fixtures and landscape spotlights. With advanced optics that provide uniform beam distribution and long-lasting durability, these LEDs are the definitive choice for projects that require maximum visibility and professional-grade reliability.
Technical Specifications: Power and Protection
The PAR38 (4.75-inch diameter) is engineered for applications where a standard light bulb simply doesn't have the reach or the ruggedness required.
Wet Location & Weatherproofing
Most PAR38 LED bulbs are designed with a sealed housing and a Wet Location rating. This makes them the industry standard for outdoor security floodlights, as they can handle direct exposure to rain, snow, and irrigation systems without failing.
High-Lumen Output
For ceilings 15 feet or higher, the PAR38 is essential. These bulbs provide the center-beam candlepower necessary to push light all the way to the floor, making them perfect for auditoriums, hotel lobbies, and vaulted residential spaces.
Security and Industrial Performance
Shatter-Resistant Optics
Safety is a priority in industrial settings. Our LED PAR38 replacements utilize high-impact polycarbonate lenses that are inherently shatter-resistant. This is a critical upgrade over traditional glass halogens in food preparation areas, workshops, and high-traffic public zones.
Precision Dimmability
Despite their high power, our PAR38s offer smooth dimming performance. This allows you to use them in residential "great rooms" to transition from bright daylight levels to a soft, warm evening glow without the flickering often associated with large-format LEDs.
