Thin-Lite

<h3>About Thin-Lite</h3><p><strong>Thin-Lite Corporation</strong> has been a trusted name in low-voltage lighting since 1969, when the company pioneered fluorescent lighting fixtures purpose-built for the RV market. More than five decades later, Thin-Lite remains a go-to manufacturer for anyone who needs reliable, energy-efficient illumination in demanding mobile and off-grid environments.</p><p>Based in Camarillo, California, Thin-Lite designs and manufactures its products proudly in America using domestic and imported parts. The brand serves a remarkably broad range of markets — from recreational vehicles and marine vessels to commercial trucks, trailers, emergency vehicles, agricultural equipment, and industrial mobile offices. Whether you&apos;re outfitting a weekend camper or a heavy-duty work rig, Thin-Lite has engineered a solution with your application in mind.</p><h3>From Fluorescent Roots to LED Innovation</h3><p>Thin-Lite built its reputation on low-voltage fluorescent fixtures that delivered exceptional brightness and durability when competitors simply couldn&apos;t match up. Over the years, the company has embraced LED technology to offer fixtures with dramatically reduced amp draw, longer service life, and improved color quality. Many of Thin-Lite&apos;s LED surface-mount fixtures feature a rated LED life of 100,000 hours and accept a wide voltage input range, making them well-suited for solar-powered and battery-dependent systems.</p><p>The product lineup spans a wide variety of form factors and mounting styles. Surface-mount ceiling fixtures, recessed fixtures, dome lights, lightbar strips, and motion-sensor units give installers the flexibility to light virtually any interior or exterior space. Diffuser options — including non-yellowing acrylic and opaque white lenses — allow users to tune light quality to their specific needs, while powder-coated aluminum housings stand up to vibration, moisture, and the rigors of life on the road or water.</p><h3>Built for RV, Marine, and Commercial Applications</h3><p>What sets Thin-Lite apart is the depth of engineering that goes into each fixture. The brand&apos;s lights are designed specifically for vehicles and vessels where power is at a premium and weight matters. Low amp draw keeps battery banks healthy on extended trips, and wide voltage compatibility means fixtures perform consistently whether running off shore power, a generator, or a solar array. Many models also support Multiplex Integration, a feature increasingly valued in modern RV electrical systems.</p><p>For commercial truck and trailer operators, Thin-Lite offers fixtures built to handle continuous vibration and harsh duty cycles. Emergency and agriculture vehicle installers benefit from the same rugged construction, while the industrial office and mobile command segment appreciates the clean, professional aesthetics of the brand&apos;s premium LED series.</p><h3>Why Choose Thin-Lite?</h3><ul style="list-style:disc"><li><strong>Pioneer heritage:</strong> Over 55 years of specialized low-voltage lighting experience</li><li><strong>American manufacturing:</strong> Designed and assembled in Camarillo, CA</li><li><strong>Broad application range:</strong> RV, marine, commercial truck, trailer, agriculture, emergency, and industrial</li><li><strong>LED efficiency:</strong> High-output fixtures with minimal amp draw and long service life</li><li><strong>Versatile form factors:</strong> Surface-mount, recessed, dome, lightbar, and motion-sensor styles</li><li><strong>Wide voltage compatibility:</strong> Most fixtures accept 8–30 VDC input for flexible power source options</li></ul><p>If you need lighting that works as hard as the vehicle or vessel it&apos;s installed in, Thin-Lite delivers the durability, efficiency, and brightness that professionals and enthusiasts have relied on for generations.</p>
