Where arm lights can help
Use external arm lights to illuminate front-facing graphics, booth walls, product displays, banner stands and compatible retail or dealer displays. They can supplement a lightbox face when needed, but do not replace its internal edge-lit or backlit modules. Pop-up, modular, aluminum and SEG frames all need a matching mounting interface; a frame brand alone does not prove fit. At CES, Canton Fair, Hannover Messe, MEDICA, LightFair, EuroShop or a local event, test the actual display and ambient light rather than assuming one universal setup.
What to compare
Compare useful illuminance, distribution, CRI, CCT, adjustment, bracket fit, input power, linking limits and transport protection. Wattage alone is not brightness, and 25W is a product size rather than a professional standard. CRI90+ is an index to compare alongside real product samples. Head tilt is different from optical beam angle.
A current product reference
The linked 25W 3250lm arm light has CRI90+, a fixed 120° beam, 359° rotation and 0–90° tilt. Current specifications list AC85–245V input, black or gray housing, a 3 m power cord, 1 m link cable and aluminum clamp. Its fixed CCT is chosen when ordering. The page currently states up to 10 compatible units per run; the final run must also respect the lowest-rated cable, connector, supply circuit and venue requirement.
Trial layouts by booth size
| Booth size | Trial fixture count |
|---|---|
| 10×10 ft: one graphic wall | 2–3 |
| 10×20 ft: graphic and product zones | 4–6 |
| 20×20 ft: multiple zones | 6–10+ |
These are planning examples, not guarantees. Adjust for graphic dimensions, mounting height, beam overlap, ambient light and accent-light needs.
LED and halogen compared
| Feature | LED | Halogen |
|---|---|---|
| Power | Compare input for equal useful light | Often higher for comparable useful light |
| Heat | Fixture and driver still need ventilation | Lamp and housing can run hot |
| Lifetime | Use model data and warranty | Use the bulb rating and replacement plan |
| Color | Depends on CCT, spectrum and aging | Depends on lamp, supply and dimming |
| Start-up | Typically immediate | Ordinary halogen lamps also light promptly |
| Maintenance | Check driver and serviceability | Allow for bulb replacement |
| Color rendering | Check CRI and real samples | Check actual lamp and real samples |
Installation and transport
Assemble the stable frame, confirm bracket dimensions and load, secure the fixture, aim and lock the head, then connect the correct cable with power off. Route cables without strain or trip hazards and link only compatible models. Rehearse before attaching the graphic if access requires it. Protect fixtures in cases sized for the actual equipment and inspect clamps, locks and leads between events.
Questions about arm lights
What is an exhibition arm light?
It is a display light on an arm that places the head in front of a graphic. The mounting method and adjustable parts depend on the model.
What is the difference between an arm light and a spotlight?
An arm describes the fixture's mounting form; a spotlight describes its optical beam. Arm lights can have wide or narrow optics. Match distribution to the task.
How many lights does a 10x10 trade show booth need?
A 10×10 ft booth may start with two or three arm lights for one graphic wall, then adjust after testing. Add task lights only where products need them.
What is CRI and why does it matter for exhibition lighting?
CRI compares selected sample colors with a reference source at a similar color temperature. CRI90 is an index, not 90% accuracy; it does not describe every color.
What is Dual CCT?
Dual CCT means two selectable color temperatures on a model that supports switching. The linked 25W 3250lm model has a fixed CCT selected when ordering: 2700–3200K, 4500–4700K or 6500–7000K.
Can I daisy-chain multiple exhibition lights?
Only for linkable models with matching cables. Follow their maximum run and the lowest-rated connector, cable, circuit and venue requirement.
How do I know which mounting clip is compatible with my display frame?
Obtain a profile drawing, groove and edge dimensions, thread and allowable load. Compare both frame and light interfaces; send photos and measurements if unsure.
Can LED lights be used near fabric?
Both LEDs and their drivers generate heat. Keep the clearances and ventilation specified for the fixture and material; lower heat than a comparable halogen light does not guarantee safe contact with fabric.
Which certification documents should I check?
Ask for the documentation for the exact model, variant and destination. Verify an ETL/UL listing in its official directory when applicable. CE is a manufacturer conformity marking supported by the EU declaration and technical documentation, rather than a generic third-party safety certification.
How long do LED arm lights last?
Use the model's stated lifetime, conditions and warranty. LED lumen maintenance is different from whole-fixture reliability; a universal 50,000-hour or ten-year promise is not justified.
Can I use them in a showroom?
Yes, if the fixture, mounting and duty cycle suit the showroom. The same portable light can serve compatible retail frames, dealer displays and product-launch installations.
What beam angle should I use for trade show lighting?
Narrow beams suit selected accents; broad beams can suit graphic washes. Use the actual beam curve and mounting distance, not a universal 30–45° rule for arm lights.
What color temperature is best for product displays?
Test the real product and finish. A warmer or cooler appearance can suit different presentation goals, but product category does not prescribe a mandatory CCT.
What lights are used for SEG displays?
Use external arm lights for front-lit SEG graphics. Internal lightboxes use edge-lit bars or backlighting modules selected for frame depth, fabric and optical layout.
How many lights does a 10x20 trade show booth need?
A 10×20 ft booth may begin with four to six fixtures across its graphics and product zones. Height, optics and measured coverage determine the final quantity.
