How to expand coverage with remote heads: sizing battery load, choosing 6V/12V units, and wiring for reliable 90-minute runtime.
Last updated: October 2025
Why remote heads
Add coverage without adding another full fixture: power additional lamp heads from a single remote-capable base unit.
Sizing load (VA/W)
Total all heads (on-board + remote) and ensure the battery supports 90 minutes. Leave margin for temperature and aging.
6V vs 12V & wire runs
Long runs favor 12V to reduce voltage drop; upsize copper on long home runs; avoid mixing wire gauges on the same circuit.
Install tips
- Label circuit voltage on J-box; record remote head count in inventory.
- Aim heads to eliminate dark spots; test for full 90 minutes on sign-off.
FAQ
Can I mix voltages?
No—match heads to the base unit voltage.
