21W Linkable LED Exhibition Arm Light – 2100lm, 3-Pin Locking Daisy Chain

Need a secure locking daisy-chain LED arm light for your trade show booth — ETL certified for McCormick Place, LVCC, and Javits Center? This 21W LED arm light delivers 2100lm with CRI 90+ through 50 high-density LEDs, covering 2–4 sqm per light. The 3-pin locking connector ensures a mechanically secure daisy-chain link that won’t accidentally disconnect during setup or teardown — the critical difference for rental fleets and high-frequency exhibitors. UL, ETL, CE, SAA, UKCA certified.

Frequently Asked Questions

Will this light fit my frame?
Yes — all four mounting options are included at no extra cost. For frames up to 55mm deep, use the Universal C-Clamp. For a flatter grip on square profiles up to 31mm, use the Square Tube Clamp. If your frame is too thick for the clamp, use the included Dual M8 Bolt-Fix Bracket — it screws directly onto the flat frame surface with no thickness limit. If your frame has a T-slot channel, use the included M8 Sliding Block Bracket — it slides into the groove and locks in place without drilling.

What’s the advantage of a 3-pin locking connector over standard push-fit?
The 3-pin locking connector physically locks into place and requires a deliberate twist to disconnect — it won’t pull loose during setup, teardown, or when cables are accidentally tugged on a busy show floor.

Is this light ETL certified for U.S. convention centers?
Yes. ETL listed by Intertek — accepted at McCormick Place, LVCC, Javits Center, and all major U.S. venues. Learn more: UL and ETL Certification for Trade Show Lights
