The ADJ ENC475 Encore FR20 DTW is a compact, professional-grade LED Fresnel fixture designed as a highly efficient and versatile replacement for small tungsten Fresnels traditionally used in studio, theater, and location lighting. The "DTW" stands for Dimmable Tunable White, indicating its core feature: the ability to smoothly dim and adjust the color temperature of its output. This fixture produces a warm white light with a color temperature that can be tuned, typically from a very warm ~2200K to a standard tungsten-like ~3200K, allowing it to match other tungsten sources on set or create specific atmospheric warmth. Its 20W LED engine provides a high light output comparable to a 100W-150W traditional Fresnel while consuming far less power and producing minimal heat.

This fixture is prized for its quality of light and silent operation. It utilizes a genuine stepped Fresnel lens to produce the characteristic soft-edged, smooth field of light that is ideal for key lighting subjects, filling shadows, or providing general wash illumination. The dimming is flicker-free and performs without the color shift towards orange that occurs when dimming incandescent bulbs. Control is straightforward and professional, offering both DMX control (with RDM for remote management) and manual control via its onboard buttons and display for standalone use. It also features a 0-100% electronic strobe effect.

Built with a durable die-cast aluminum housing, the FR20 DTW is both lightweight and robust. Its fanless, passive cooling design ensures it is completely silent, making it perfect for film sets, television studios, and theatrical environments where microphone pickup of fan noise is a concern. With its combination of tunable white light, excellent output, silent operation, and professional control, it is an essential tool for cinematographers, broadcasters, and theater technicians seeking the quality of a Fresnel with the benefits of modern LED technology.
