A compatible, purpose-built linkable lighting system can simplify booth wiring. Plan the exact models, connections and complete circuit load before deciding how many fixtures to link. One outlet does not guarantee adequate capacity or lower event electrical fees.
What linking means
The first fixture receives power through its specified input cable; subsequent compatible fixtures connect to the designated pass-through outputs. “Daisy-chain” describes this physical cable layout, not an electrical series circuit through the LEDs. Use only the manufacturer-approved configuration. Linking fixtures is different from plugging one power strip into another.
Check the limit for the exact model
| Model | Published maximum per run | Nominal fixture wattage at that maximum |
|---|---|---|
| 25W fixed-CCT arm light | 10 | 250W |
| 25W Tri-CCT arm light | 10 | 250W |
| 50W fixed-CCT arm light, black or silver | 6 | 300W |
| 50W Tri-CCT arm light | 10 | 500W |
These are the published configurations for these specific products, not limits for every 25W or 50W light. The permitted number may be lower. Check the delivered model’s instructions, supply voltage, input current, main cable, link cables, connectors, pass-through ratings and venue approval. The input lead supplies the whole run; each downstream connection must also remain within its documented limit. Do not infer connector capacity from the fixture’s wattage.
Budget the whole circuit
Add the specified AC input loads of lights, screens, chargers and demonstration equipment sharing the circuit. Nominal fixture watts are a first estimate, not a complete current calculation. LED driver efficiency, power factor and switch-on inrush can matter; use the complete fixture’s input specifications without counting an included driver twice. Have the venue’s electrical provider confirm usable capacity, other shared loads and applicable continuous-load rules. Booth dimensions do not establish a standard power allocation.
As an arithmetic example, four fixtures rated 25W total 100W nominally. That does not prove a particular supply has 100W available or approve the chain. Two outlets may share one circuit, and a power strip adds sockets rather than independent circuits or capacity. Follow the approved distribution equipment’s instructions; do not chain ordinary power strips.
Can different wattages share a run?
Different wattages alone do not cause uneven power distribution. Mixing is acceptable only when the manufacturer confirms compatibility of the exact models, voltage, connectors and pass-through load, including the combined limit. Matching connector shapes and adding watts are insufficient. Without that confirmation, use separate approved lighting runs and verify their combined supply load.
Connect and route cables before energizing
- Disconnect the supply, inspect cables and connectors, and mount the fixtures securely on suitable supports.
- Connect the designated outputs to the next compatible inputs using approved link cables. Fit the main supply cable while the source remains disconnected.
- Check seating, strain relief, the number of fixtures and all load limits. Protect cable routes from sharp edges, pinching and pedestrian traffic using permitted supports or covers.
- Energize the completed arrangement as instructed and check every light. Disconnect before moving or reseating connections.
Longer runs require the correct connector, voltage/current rating, conductor size and permitted length for the complete downstream load. Do not make improvised adapters. Follow cable-reel instructions and wound/unwound load ratings; a tightly coiled cable is not automatically suitable under load. There is no guaranteed five-minute installation time.
Find the fault without opening live equipment
- No lights: have the venue confirm the supply, then inspect the disconnected main cable and first input.
- One light off: disconnect and inspect its external connections. A cable, fixture or driver fault is possible; a loose plug is not the only explanation.
- All lights after one point off: disconnect and inspect the preceding pass-through output and link cable.
- Flicker or tripping: stop and review connections, compatibility, full load and driver/control requirements. Inrush, supply problems and equipment faults may need the supplier or qualified electrical provider.
Remove damaged parts from service. If a connector is unusually hot, discoloured or smells burnt, disconnect the system and arrange inspection; do not keep resetting protection or bypass it. Use approved replacements and follow the supplier’s test procedure. Compare linkable booth lights by their exact documentation, then test the complete approved setup before the show opens.
