The trade show industry has largely shifted to LED lighting over the past decade. For most modern exhibition booths, LED is the practical first choice. But understanding why — and when halogen may still be relevant — helps exhibitors make better purchasing decisions.
Here is a direct comparison of LED vs. halogen for trade show applications.
LED vs Halogen: Direct Comparison
| Specification | LED Exhibition Light | Halogen Exhibition Light |
|---|---|---|
| Lifespan | 50,000 hours | ~2,000 hours |
| Energy efficiency | High (most energy becomes light) | Lower (~90% energy becomes heat) |
| Heat output | Low — safe near fabric and SEG | Higher — check clearance near fabric displays |
| Color rendering | CRI 90+ available | CRI ~100 natural spectrum |
| Color temperature | Selectable (CCT options) | Fixed warm white (~2700K–3000K) |
| Lamp replacement | Not required | Replaceable R7s or MR16 lamp |
| Power consumption | 25W–50W for full booth coverage | 150W–300W for equivalent output |
| Venue compatibility | Generally accepted everywhere | Check venue requirements before use |
| Certification | UL, ETL, CE, UKCA available | Available on professional fixtures |
Heat Output: The Key Practical Difference
Halogen lamps convert a significant portion of their energy into heat. In a trade show environment, this has practical implications:
- Clearance from fabric displays — SEG fabric lightboxes, fabric backdrops, and popup displays require adequate clearance from halogen fixtures.
- Venue requirements — Some convention centers restrict or require pre-approval for halogen lighting. Always check the exhibitor manual for your specific show.
- Staff comfort — Higher heat output in a warm exhibition hall is worth considering for multi-day shows.
LED fixtures run significantly cooler, which simplifies venue compliance and reduces heat-related considerations near display materials.
Lifespan and Lamp Replacement
A halogen lamp lasts approximately 2,000 hours under normal conditions. In trade show use — with frequent transport, vibration, and temperature cycling — real-world lifespan may be shorter. Exhibitors using halogen fixtures should carry spare lamps as standard practice.
LED fixtures rated at 50,000 hours require no lamp replacements under normal use. This reduces ongoing maintenance and eliminates mid-show lamp failures.
One practical advantage of halogen: the lamp is user-replaceable. For display contractors who maintain existing halogen systems, this can be convenient when a compatible replacement lamp is readily available.
Power Consumption
Standard trade show booth power allocations are typically 500W–1,000W for a 10×10 booth. Halogen fixtures at 150W–200W each consume a significant portion of this allocation. LED fixtures producing equivalent output at 25W–50W leave more capacity for monitors, demo equipment, and other electronics.
Color Temperature Flexibility
Halogen produces a fixed warm white output (~2700K–3000K) — a familiar, traditional light character that works well for certain graphics, fabric backdrops, and warm-toned displays.
LED fixtures are available across the full color temperature range — 2800K through 6800K — with some fixtures offering tunable white for on-site adjustment. This flexibility is an advantage for exhibitors who need to adapt to different products, venues, or brand requirements.

CRI: Color Rendering Quality
Halogen produces light with a CRI close to 100 — a natural, continuous spectrum. This is a genuine advantage for applications where absolute color accuracy is critical, such as fine art or gemstone displays.
Professional LED exhibition fixtures rated CRI 90+ close this gap significantly. For the vast majority of trade show applications, CRI 90+ LED provides color rendering that is indistinguishable from halogen in practice.

When LED Is the Better Choice
- Building a new booth from scratch
- Venues with strict halogen restrictions
- Booths with fabric backdrops, SEG displays, or popup systems
- Exhibitors who need color temperature flexibility
- High-frequency exhibitors who want to minimize maintenance
When Halogen May Still Be Relevant
- Existing display systems built around halogen fixtures
- Applications where a replaceable R7s lamp is preferred
- Exhibitors who specifically want the traditional warm halogen light character
- Venues where halogen is permitted and the application is compatible

Frequently Asked Questions
Is LED or halogen better for trade show booth lighting?
For most modern trade show applications, LED is the practical choice: lower heat output, longer lifespan (50,000 vs ~2,000 hours), lower power consumption, and no mid-show lamp failures. Halogen remains relevant for specific applications — particularly existing display systems or where a replaceable lamp design is preferred. Always check venue requirements before using halogen.
Do halogen lights get too hot for trade show booths?
Halogen lamps produce more heat than LED fixtures. This requires adequate clearance from fabric backdrops, SEG displays, and popup booths. Some venues restrict halogen use — always check the exhibitor manual for your specific show. LED fixtures run significantly cooler and are generally easier to use near fabric display materials.
How long do LED trade show lights last compared to halogen?
LED exhibition fixtures are rated at 50,000 hours — approximately 25 times longer than halogen lamps (~2,000 hours). In trade show use, transport and temperature cycling may reduce halogen lamp life further. Halogen lamps are user-replaceable; LED fixtures typically require no lamp replacement.
Does LED have better color rendering than halogen?
Halogen has a natural CRI of ~100. Professional LED fixtures rated CRI 90+ provide color rendering that is indistinguishable from halogen for most exhibition purposes. For applications requiring absolute color accuracy, halogen's natural spectrum remains a consideration.
Are LED trade show lights more expensive than halogen?
LED fixtures typically have a higher upfront cost but lower total cost of ownership — no lamp replacements, lower power consumption, and longer fixture life. For high-frequency exhibitors, LED is generally more economical over multiple shows.
