The PAR38 LED bulb brings the beauty of natural white light to both retrofit projects and new lighting installations, creating an atmosphere that mirrors the feel of daylight throughout the day. Utilizing a breakthrough three-channel light engine combined with proprietary optics and precise color mixing technology, it produces a wide correlated color temperature (CCT) range from 1,800 K to 5,500 K. This technology enables the lamp to replicate natural white light more faithfully than conventional LED sources, producing light that feels balanced, vibrant, and comfortable to the eye. Its high fidelity of color, with a CRI greater than 90 and R9 above 80, ensures that colors, finishes, and materials appear authentic and vivid under any setting—from the warm glow of morning to the cool brightness of midday.
The bulb’s Natural Show capability allows it to integrate seamlessly into Lutron’s dynamic lighting ecosystem, automatically adjusting intensity and color temperature throughout the day to emulate natural daylight cycles. This feature helps synchronize interior lighting with the human circadian rhythm by mimicking outdoor light patterns, shifting from cool, bright tones at noon to warmer, softer hues in the evening. The result is a more natural, health-conscious lighting experience that enhances well-being and visual comfort. TruBeam optical technology further refines light distribution, maintaining uniform color and consistency across every beam angle, whether it is used as a focused spot or a wide flood source.
The PAR38 LED bulb is fully compatible with Lutron’s HomeWorks, Athena, and myRoom control systems. Integrated wireless control is made possible through Clear Connect Type X (CCX) technology, which not only allows for native wireless operation but also supports diagnostic reporting for input voltage and connectivity status. The single-source multi-die modular LED emitter is binned to tight 3-step MacAdam ellipses, ensuring consistent color quality from one lamp to another. The fixture’s dimming capabilities are exceptional—dimmable from 100% down to 0.1% measured luminous flux—allowing users to create seamless transitions in brightness and warmth that replicate the behavior of incandescent light sources.
With an output of approximately 1,000 to 1,100 lumens, the PAR38 LED bulb provides the power and clarity of a traditional 75 W or 100 W halogen lamp while maintaining remarkable efficiency. Its optical system produces precise beam options, including 15° spot, 25° flood, 40° wide flood, and 60° very wide flood patterns, making it suitable for a wide range of lighting applications—from accent lighting to general illumination. Compatible with both E26 and GU24 bases, it easily fits into standard six-inch recessed or track lighting fixtures. The bulb operates on 120 V 60 Hz power with a maximum current of 120 mA and maintains a power factor greater than 0.9.
Constructed for reliability, the LED light source has an estimated useful life of at least 50,000 hours at 70% lumen maintenance, based on IES LM-80 testing data. It performs effectively in environments ranging from 32°F to 122°F (0°C to 50°C), and extended operation is possible in colder ambient temperatures down to -13°F (-25°C). The lamp is UL, cUL, RoHS, and FCC Class B certified and is rated for use in damp locations (IP20). Outdoor use is permitted for enclosed or covered residential patio applications.
Every aspect of this PAR38 LED bulb has been built for consistency, versatility, and long-term performance. The three-channel light engine produces an exceptionally broad spectrum of natural white light, enhancing architectural details and interior finishes. The result is a refined, adaptive lighting source that harmonizes technology, control, and aesthetic precision—ideal for modern spaces seeking the look and feel of true natural daylight with the intelligence of integrated wireless control. A five-year warranty covers the fixture, LED components, and dimming functions, ensuring lasting quality and reliability across diverse residential and commercial applications.
