How to Choose the Right LED Module for Your Trade Show Lightbox: 7W vs 12W vs 13W vs 20W Guide

July 30, 2026

Choosing the wrong LED module for your trade show lightbox is one of the most common — and costly — mistakes exhibitors make. Too dim, and your fabric graphics look flat. Too bright, and you risk hotspots that distract from your brand message.

This guide breaks down four purpose-built LED modules from BOOTH LIGHTS, so you can match the right wattage to your lightbox size and application.

Quick Selection Guide

Wattage	Best For	Lightbox Size	Brightness
7W Side-Lit Module	Small signage, countertop displays	Up to 60×60cm	700lm
12W Backlit Module	MODULAP, SEG fabric lightboxes	60–120cm frames	1320lm
13W Edge-Lit Bar	Edge-lit panels, slim lightboxes	Standard frame widths	1300lm
20W LED Strip	Large lightboxes, high-brightness venues	100cm+ frames	2200lm

7W DC24V Side-Lit LED Module – For Small Displays

The 7W Side-Lit Module is designed for compact lightbox applications — countertop displays, small signage panels, and portable pop-up systems where space and power consumption matter.

Key specs: DC24V, 700lm, optical lens for even side-lighting, 3-pin connector (3P plug), available in Square and Round form factors.

Choose this if: Your lightbox frame edge is under 60cm, or you're building a low-power portable display system.

12W LED Backlit Module – For MODULAP & SEG Fabric Lightboxes

The 12W Backlit Module is the go-to choice for standard trade show fabric lightboxes — particularly MODULAP and SEG aluminum frame systems used at most major exhibitions.

Key specs: DC24V, 1320lm, plug-in connector for daisy-chain wiring, CRI90+, dimmable, available in 2700–3200K / 4200–4500K / 6500–7000K.

Choose this if: You're using a MODULAP, Expolinc, or standard SEG fabric frame and need reliable, even backlit illumination across the panel.

13W ETL Listed Edge-Lit Bar – For Slim & Edge-Lit Lightboxes

The 13W Edge-Lit Bar is purpose-built for edge-lit lightbox designs — where the light source sits along the frame edge and illuminates the panel from the side inward. ETL listed for North American exhibition venues.

Key specs: DC24V, 1300lm, Molex 5557 connector, CRI90+, 470mm length fits standard frame widths.

Choose this if: Your lightbox uses an edge-lit design (light enters from the side, not behind), or you need ETL certification for US/Canada venues.

20W LED Strip – For Large Lightboxes & High-Brightness Applications

The 20W LED Strip delivers the highest output in the lineup — 2200lm per strip — making it the right choice for large-format lightboxes, island booths, and venues that demand maximum visual impact.

Key specs: DC24V, 2200lm, CRI90+, UL listed, 10×40° transparent lens, Molex 5557 connector, dimmable.

Choose this if: Your lightbox frame edge exceeds 100cm, you're in a brightly lit venue, or UL certification is required by the exhibition hall.

How to Calculate How Many Modules You Need

Quantity is based on the length of each frame edge, not total lightbox area. Install on opposite edges (top + bottom, or left + right) for best uniformity.
