If you're outfitting a 10×10 trade show booth and need more brightness than a standard 1200–1800lm arm light without jumping to a 35W unit, the 21W 2400lm display arm light sits in a useful middle ground. Here's what it actually delivers — and who it's best suited for.
What Makes 2400lm Different from Standard 21W Lights?
Most 21W booth lights on the market produce 1200–1800lm. This unit delivers 2400lm — roughly 30–50% more output at the same wattage — thanks to higher-efficiency LED chips. In a busy exhibition hall with strong overhead ambient lighting, that extra brightness is the difference between a display that holds its own and one that looks flat.
