XLR Trigger Box For Lights - Relay Switching, Current Limits, and DMX Alternative¶

LIKELY ELECTRICAL SAFETY

Summary¶

The XLR Triggers Box can switch outputs from Flair, but using it to turn modern lights on/off requires care. The chat answer separated three cases: trigger a DMX cue when possible, use a properly rated relay/contactor for higher-current switching, and do not assume digital ballast/LED fixtures behave like tungsten bulbs when power is cut and restored.

Symptoms / Questions¶

Operator wants to connect a light to the trigger box for on/off control.
Light may be an Aputure / digital ballast / LED fixture.
User is unsure whether to use trigger output, mains breakout, relay, or DMX.

Settings Location¶

Task	Flair location
Program trigger output frames	Setups -> Outputs
Test trigger outputs	Setups -> Outputs -> Test Outputs
External camera trigger	Setups -> External Camera Setup
DMX alternative	Setups -> DMX or Setups -> External Devices -> DMX / Root DMX

Community Solutions¶

[LIKELY] Prefer DMX For Modern Lights¶

For Aputure-style digital lights, triggering DMX is usually more appropriate than cutting mains power. Modern LED fixtures and digital ballasts may not switch predictably like tungsten lamps when their mains input is toggled.

Confidence: 0.76

[LIKELY] Use A Proper External Relay For High Current Loads¶

If the light/effect must be power-switched, use the trigger box to drive a properly rated high-current relay or contactor with a 12V or 24V DC coil, rather than asking the trigger box relay to carry a questionable load.

Confidence: 0.74

[CONFIRMED] Respect Trigger Box Current Ratings¶

The Triggers Box Mk II QSG lists relay output limits and pinouts. The chat referenced 8Amp Max; the QSG also states output constraints including 250VAC/30VDC 8A Max at the connector reference, and separate relay-output notes for voltage/current and inductive-load limits. Treat inductive loads conservatively and ask MRMC for final confirmation.

Confidence: 0.82

2026-05-19 21:49	Stafford	XLR trigger box has mains breakout cables; thought maybe 10A, needed QSG check.

2026-05-19 21:56	Timothy Heys Cerchio	Stated `8Amp Max`.
2026-05-19 22:05	Timothy Heys Cerchio	Warned modern digital ballast lights like Aputures may not work well with mains power switching.
2026-05-19 22:30	Chavez.Camera	Suggested DMX is probably best.
2026-05-20 04:15	Peter Constan-Tatos	Best method is high-current relay with 12V or 24V DC coil.

2026-05-19 21:49 - ~ Stafford: XLR trigger box has mains breakout cables for 110V I'd need to check the QSG but i think 10A

2026-05-19 22:05 - Timothy Heys Cerchio: Though, I fear, modern digital ballast lights like the Aputures might not actually work well with Mains Power switching ON/OFF... 😬
2026-05-19 22:07 - Timothy Heys Cerchio: Or, let's say, definitely not like an analogue tungsten light bulb would 😉
2026-05-19 22:30 - ~ Chavez.Camera: Probably best to trigger DMX
