Walk into any trade show and you'll immediately notice which booths stand out. It's rarely the biggest booth or the most expensive display — it's almost always the one with the best lighting. Great trade show lighting makes products look premium, draws foot traffic, and keeps visitors engaged longer.
But choosing the right lights isn't as simple as picking the brightest option. This guide breaks down the three most important factors: CRI, wattage, and color temperature — and how to choose the right combination for your booth and products.
What Is CRI and Why Does It Matter for Trade Shows?
CRI stands for Color Rendering Index. It measures how accurately a light source renders colors compared to natural daylight, on a scale of 0 to 100.
- CRI 70–79: Colors appear dull and slightly off. Acceptable for warehouses, not for trade shows.
- CRI 80–89: Decent color accuracy. Common in office lighting.
- CRI 90–95: Excellent color accuracy. Industry standard for retail and trade show lighting.
- CRI 95+: Near-perfect color rendering. Used in photography studios and jewelry displays.
For trade shows, CRI 90+ is the minimum you should accept. Below CRI 90, product colors shift — reds look orange, whites look yellow, and fabrics lose their vibrancy. This directly affects how buyers perceive your products.
All Booth Lights products are rated CRI 90+, ensuring your products look exactly as intended under show floor conditions.
How Much Wattage Do You Need?
Wattage determines brightness (measured in lumens). The right wattage depends on three factors: your booth size, the venue's ambient lighting, and your product type.
By Booth Size
- 10x10 booth: 16W–25W per light, 2–3 lights recommended
- 10x20 booth: 25W–35W per light, 4–6 lights recommended
- 20x20 booth or larger: 35W–50W per light, 6+ lights depending on layout
By Venue Brightness
- Bright convention halls (e.g., Las Vegas Convention Center): Higher wattage needed to compete with ambient light. Go 25W minimum.
- Darker or older venues: 16W–21W may be sufficient.
- Outdoor or semi-outdoor events: 35W+ recommended.
By Product Type
- Jewelry, watches, luxury goods: High brightness + CRI 95+ for maximum sparkle and color accuracy
- Apparel, textiles: Medium brightness, CRI 90+, neutral color temperature
- Electronics, tech products: Medium-high brightness, cool white (5000K–6500K)
- Food, lifestyle products: Warm white (3000K), medium brightness
Our 25W Dual CCT LED Arm Light covers most booth sizes and product types, with switchable color temperature built in.
Color Temperature: Warm, Neutral, or Cool?
Color temperature is measured in Kelvin (K). It determines the "mood" of your lighting and has a significant impact on how products are perceived.
3000K — Warm White
Creates a cozy, premium, boutique atmosphere. Makes wood tones, leather, and earth colors look rich and inviting.
Best for: furniture, home décor, food & beverage, lifestyle brands, luxury goods
4000K–4500K — Neutral White
The most versatile option. Renders colors accurately without adding warmth or coolness. Looks clean and professional.
Best for: general merchandise, apparel, B2B products, most trade show applications
5000K–6500K — Cool White / Daylight
Crisp, high-contrast light that emphasizes precision and clarity. Makes metallic surfaces and screens look sharp.
Best for: electronics, medical devices, industrial equipment, tech products
Can't Decide? Choose Tunable White
If you exhibit at multiple shows with different product mixes, a tunable white LED arm light lets you switch color temperatures without buying multiple fixtures. Our 25W Dual CCT LED Display Arm Light switches between warm and cool white, giving you flexibility for any venue or product.
Beam Angle: Spot vs. Flood
Beam angle determines how wide or narrow the light spreads.
- 15°–25° (Spot): Tight, focused beam. Ideal for highlighting a single product or creating dramatic accent lighting.
- 30°–45° (Narrow Flood): Good balance of focus and coverage. Works well for most booth displays.
- 60°+ (Wide Flood): Broad coverage. Better for general ambient fill than product spotlighting.
For most trade show arm lights, a 30°–45° beam angle is the sweet spot — focused enough to highlight products, wide enough to cover a display panel or banner.
UL and ETL Certification: Non-Negotiable for US Shows
If you exhibit at major US trade shows, your lighting must be UL or ETL certified. This is not optional — it's a venue requirement enforced by show management.
Major venues that require certified lighting include:
- McCormick Place, Chicago
- Las Vegas Convention Center
- Jacob Javits Center, New York
- Orange County Convention Center, Orlando
- Georgia World Congress Center, Atlanta
Non-certified lights can be removed from your booth by show electricians, leaving you with no lighting on the first day of the show. All Booth Lights products carry both UL and ETL certification, so you're always compliant.

Frequently Asked Questions
What CRI do I need for trade show lighting?
CRI 90+ is the industry standard. Below CRI 90, product colors will appear inaccurate, which can negatively affect buyer perception.
Is 25W enough for a trade show booth?
For a 10x10 booth, yes. Two 25W arm lights provide excellent coverage for most standard displays. For larger booths or very bright venues, consider 35W.
What color temperature is best for trade shows?
4500K (neutral white) works for most applications. Choose 3000K for warm lifestyle products and 6000K+ for tech or industrial products.
Do I need UL certified lights for trade shows?
Yes, if you exhibit at major US convention centers. UL or ETL certification is required by most venues and enforced on the show floor.
How many lights do I need for a 10x10 booth?
2–3 LED arm lights is the standard recommendation. Start with 2 and add a third if you have multiple product zones or a backlit display.
