Choosing the Right Wattage

Wattage measures power draw, while lumen output indicates brightness. Compare both alongside beam angle, mounting distance and the area you need to cover:

Model Watts Lumens Best For
11W Accent Light 11W — Accent, EU shows, luxury brands
21W Linkable 21W 2,100lm Shelving, daisy chain setups
25W Display Arm 25W 3,250lm 10×10 booths, fabric displays
35W Exhibition 35W 3,500lm 10×20, premium inline
50W Linkable 50W 5,500lm 20×20+, island booths, max brightness

Color Temperature Guide

Color temperature (measured in Kelvin) affects how your products and graphics look. Several BoothLights arm-light models are available in multiple color temperatures, including switchable Tri-CCT options:

Which Color Temperature Should You Choose?

  • 3000K (Warm White): Best for food, luxury goods, fashion, and wood/natural materials. Creates a warm, inviting atmosphere.
  • 4500K (Neutral White): The most versatile choice. Accurate color rendering for most products and graphics. Recommended for first-time exhibitors.
  • 6000K (Cool White / Daylight): Best for technology, automotive, industrial, and medical products. Creates a clean, clinical look.

Many BoothLights arm lights use CRI90+ LEDs for accurate product and graphic color. Check the exact model and variant before ordering, because CRI and available color temperatures can differ.

ETL & UL Certification

Many US venues require booth electrical equipment to carry an acceptable safety listing, but rules vary by event, venue and installation. Check the current exhibitor manual and confirm the exact fixture, driver, plug and configuration before ordering.

Venue Documentation to Confirm
McCormick Place, Chicago Check the current exhibitor manual and electrical contractor
Las Vegas Convention Center Check the current exhibitor manual and electrical contractor
Orange County Convention Center Check the current exhibitor manual and electrical contractor
Jacob K. Javits Center, NYC Check the current exhibitor manual and electrical contractor
European venues (Messe) Check the current venue and destination-market requirements

Certification varies by model, configuration and destination market. Verify the listing or declaration shown for the exact product variant, and request supporting documentation when the venue requires it.

Daisy Chaining Explained

Daisy chaining lets compatible lights share a power feed, which can simplify booth wiring where floor outlets are limited. Venue rules for outlets, extension leads and electrical work vary, so confirm the planned circuit before setup.

Our Linkable Models

  • 21W Linkable: Designed for up to 10 lights where the exact model, plug, cable, supply voltage and venue circuit permit; choose the actual run for the site conditions
  • 50W Linkable: Follow the connection limit stated for the exact model and configuration; choose the actual run for the site conditions

Models listed as non-linkable need a separate compatible power connection for each light. Confirm the exact product configuration and plan power drops before ordering.

Lighting by Industry

Different industries have different lighting priorities. Here’s a quick reference:

Fashion & Cosmetics

3000K Warm White

CRI90+ can improve color fidelity. Warm light can flatter skin tones and fabrics. A 10×10 booth may start with 3–4 25W lights, then adjust for display width and ambient light.

Technology & Electronics

6000K Cool White

Clean, bright light that makes screens and hardware look sharp. 50W for large displays.

Food & Beverage

3000K–4500K

Warm light can enhance food colors. A CRI90+ option supports more accurate product appearance.

Luxury & Premium Brands

3000K + Accent Lights

Combine 25W backwall lights with 11W accent lights for a layered, premium look.

Healthcare & Medical

4500K–6000K

Neutral to cool white can create a clinical, professional appearance. Confirm the exact model documentation required by the venue.

Automotive & Industrial

6000K Cool White

Maximum brightness to showcase finishes and details. 50W linkable for large displays.

Frequently Asked Questions

What is the most important factor in trade show booth lighting?
No single specification decides the result. CRI affects color fidelity, while lumen output, beam angle, mounting distance, placement and ambient light determine coverage. A CRI90+ option can improve color accuracy; check the stated specifications for the exact model.
How far in advance should I order trade show lights?
Plan at least 3–4 weeks before the show so the estimated 8–18-business-day delivery window still leaves time for testing and adjustments. Allow more time for large, custom or venue-documented orders. Displayed prices include worldwide shipping and duties.
Can I use the same lights at shows in the US and Europe?
Compatibility depends on the exact input-voltage range, plug, driver, certification documents and venue rules. Plug availability varies by model. Confirm the selected configuration and destination requirements before ordering; a plug adapter alone does not make every model suitable for every market.
What happens if my lights fail ETL inspection at the venue?
A venue or its electrical contractor may reject equipment that does not meet the current rules or may require it to be removed from service. Certification varies by model and configuration, and the event electrician has final authority. Verify the selected product and documents against the current exhibitor manual before ordering.
Do you offer volume discounts for exhibit houses and rental companies?
Yes. We sell direct from the factory and offer volume pricing for exhibit houses, rental companies, and distributors. Contact us for a custom quote on orders of 10+ units.
