Buying LED trade show lights for the first time — or switching suppliers — can feel overwhelming. The market is flooded with options at wildly different price points, and the wrong choice can mean non-compliant fixtures, poor color rendering, or lights that fail mid-show.
This guide gives you the exact questions to ask any trade show display light supplier before you commit, along with the answers you should expect from a reputable manufacturer.
1. Are Your Fixtures ETL or UL Listed?
This is the single most important question. Major US trade show venues — including McCormick Place, LVCC, and the Orange County Convention Center — require all electrical equipment to be UL or ETL listed. Non-compliant fixtures can be confiscated by show management before your booth even opens.
What to expect: A reputable supplier will provide the certification number and the name of the testing laboratory. Ask to see the actual certificate, not just a logo on a product page.
Red flag: "CE certified" alone is not sufficient for US venues. CE is a European standard. Insist on ETL or UL.
2. What Is the CRI of Your Trade Show Display Lights?
CRI (Color Rendering Index) determines how accurately your products and graphics will look under the light. For trade show applications, CRI 90+ is the professional standard.
What to expect: The supplier should state the exact CRI value (e.g., CRI 92) and be able to provide a photometric test report (IES file or LM-79 report) to back it up.
Red flag: Vague answers like "high CRI" or "CRI 80+" without a specific number. CRI 80 and CRI 95 are very different in practice.
3. What Voltage Range Do Your Lights Support?
If you exhibit internationally, universal voltage (AC 100–265V) is essential. US-only fixtures (AC 110–120V) will fail or be damaged if plugged into European or Asian power systems.
What to expect: AC 80–265V universal voltage, confirmed on the product spec sheet.
4. How Does the Mounting System Work?
Trade show booths use a variety of systems — pipe-and-drape, panel systems, truss, and custom builds. Your lighting needs to mount securely on your specific setup without tools or special hardware.
What to expect: The supplier should be able to confirm compatibility with standard 1"–2" pipes and common panel systems. Ask for photos or videos of the mounting in action.
Red flag: Proprietary mounting systems that only work with the supplier's own booth hardware.
5. Can I Link Multiple Units Together?
For larger booths, daisy-chaining lights from a single power outlet is a major convenience — and often a venue requirement (fewer power drops = lower electrical costs). Ask how many units can be linked and what the maximum load is.
What to expect: Professional LED trade show lights should support linking up to 8–10 units per circuit.
6. What Is the Beam Angle, and Is It Adjustable?
Beam angle determines how focused or spread out the light is. A narrow beam (15–25°) is ideal for spotlighting products. A wide beam (60–120°) works better for illuminating large graphics or backdrops.
What to expect: The supplier should provide the beam angle in the spec sheet. Adjustable-head fixtures give you more flexibility across different booth configurations.
7. What Is the Warranty and What Does It Cover?
Trade show lights take a beating — packed, unpacked, clamped, adjusted, and transported repeatedly. A solid warranty signals product confidence.
What to expect: Minimum 2-year warranty covering manufacturing defects. Ask specifically whether the warranty covers the driver (the most common failure point in LED fixtures) and what the replacement process looks like.
Red flag: 30-day or 90-day warranties, or warranties that require you to ship the product back to China at your own cost.
8. Are You the Manufacturer or a Reseller?
This question has major implications for price, lead time, customization, and support. Direct manufacturers can offer better pricing, faster issue resolution, and custom configurations such as color temperature, wattage, finish and plug type. Resellers add margin and often have limited technical knowledge.
What to expect: A manufacturer should be able to provide product documentation, OEM/ODM capability details, and direct engineering support.
9. What Are the Lead Times and Shipping Options?
Trade shows have hard deadlines. A supplier who cannot explain processing time, transit time, customs handling and delivery costs clearly is a liability.
What to expect: Clear timelines for in-stock items, made-to-order items and bulk orders. For Europe-bound Booth Lights orders, shipping is free, duties and import taxes are included in the checkout price, and estimated delivery is 8-18 business days after order placement. Ask whether expedited options are available when your show date is close.
10. Do You Have References or Case Studies from Other Exhibitors?
Real-world performance matters more than spec sheets. Ask for references from exhibitors in your industry, or look for verified reviews that mention specific trade shows and venues.
What to expect: A confident supplier will point you to customer testimonials, case studies, or a portfolio of booth installations. Be skeptical of suppliers who can only show product photos — never real booth setups.

Frequently Asked Questions
What certifications do trade show lights need for US venues?
ETL or UL listing is required at most major US trade show venues, including McCormick Place, LVCC, and the Orange County Convention Center. CE certification alone does not meet US venue requirements.
Is factory-direct always better than buying from a distributor?
For standard products, buying direct typically offers better pricing and faster issue resolution. For buyers who need local stock, fast returns, or consolidated orders from multiple brands, a reputable distributor can add value.
What CRI is acceptable for trade show display lights?
CRI 90+ is the professional standard. CRI 80 is the minimum for general commercial use but is not recommended for product-focused trade show displays where color accuracy matters.
How do I know if a supplier is actually a manufacturer?
Ask for product documentation, OEM/ODM capabilities, and engineering contacts. Legitimate manufacturers can explain wattage, driver, beam angle, voltage, certification and customization details clearly.
What should I do if my trade show lights fail at the show?
Always bring 1–2 spare fixtures as backup. For critical shows, carry a spare driver (power supply) as well — it is a common failure point and easy to swap on-site.
Can I get custom color temperatures for my booth lighting?
Yes, if you are buying direct. Many manufacturers offer 2800K–7000K CCT options, and some fixtures support adjustable CCT via a switch or remote. Minimum order quantities typically apply for custom configurations.
