The Ketra A20 LED lamp delivers full-spectrum light with unparalleled fidelity and versatility, making it ideal for wall sconces, decorative pendants, and table lamps. At its core, the lamp features a proprietary four-channel light engine that produces both natural white light across an unprecedented color temperature range of 1,400K to 10,000K and 16.7 million fully saturated and pastel colors. This extensive range allows for warm golden tones reminiscent of candlelight as well as cool, blue-hued whites, enabling precise rendering of art, furnishings, and interior details. The A20 lamp’s 90+ CRI and R9 greater than 90 ensure superior color rendering, while the Vibrancy control allows subtle manipulation of spectral composition to influence color perception without altering overall intensity or color temperature.
Color Lock technology continuously monitors and adjusts light output to maintain consistent color over the 50,000-hour rated life to L70, preserving accurate color at a one-step MacAdam ellipse across the lamp’s lifetime. The A20 lamp supports both omnidirectional 600-lumen and semi-directional 800-lumen beam angles, providing flexibility for diverse residential applications. It is compatible with E26 and GU24 bases, facilitating retrofit installations without modification of existing fixtures. The lamp is dimmable from 0.1% to 100%, allowing for precise control over brightness in any environment.
The A20 LED lamp is natively compatible with Lutron wireless control systems, utilizing Clear Connect Type X RF communication to integrate seamlessly with HomeWorks and Athena systems. Field adjustments, scenes, and wireless control are fully supported without additional wiring, providing ease of installation and long-term adaptability. Rated for UL Damp Locations and IP20, the lamp operates in ambient temperatures from 32°F to 122°F (0°C to 50°C), with an extended range of -13°F to 32°F (-25°C to 0°C), and supports relative humidity of 0% to 95% non-condensing. Outdoor use is permitted only in residential enclosed or covered patio applications.
With a luminous output comparable to 40W to 60W incandescent lamps, the Ketra A20 LED lamp combines superior spectral quality, tunable color, and wireless integration to create both functional and experiential lighting. Its combination of omnidirectional and semi-directional beams, long lifetime with continuous Color Lock, and compatibility with Lutron controls make it a versatile and reliable solution for residential spaces demanding exceptional light quality. Regulatory approvals include UL, cUL, RoHS, and FCC Class B, ensuring compliance and safety in residential installations.
