21W LED Exhibition Arm Light for Trade Show Booth – Clamp Mount, Swivel Head, Silver
What's the best way to illuminate a trade show backwall without complicated wiring or heavy fixtures?
This brushed silver LED flood light clamps directly onto your booth frame and floods your backwall graphics with bright, neutral white light — no tools, no electrician, no hassle. The swivel and tilt head lets you aim the beam exactly where it counts. At 21W, it delivers 2100–2500lm of output and runs cool without overheating during a full show day.

3000K warm white suits jewelry, food, and lifestyle brands. 4500K daylight white works for apparel and general merchandise. 6000K cool white is best for tech, industrial, and high-contrast graphic panels. Each light ships in the color temperature you select — it is a fixed setting, not switchable.
