Many retrofit boxes have only a live conductor at the switch. Factories therefore offer no-neutral (single live) modules. They work — until the LED load is too small, the bypass is missing, or the market expects always-on status LEDs. Buyers should treat wiring as a first-class RFQ field, not a footnote.
Neutral preferred
- Stable power for the radio module and backlight
- Better behaviour with low-wattage LED lamps
- Default recommendation for new apartment fit-out
No-neutral (single live)
- Useful for retrofit where pulling N is impossible
- May need minimum load or capacitor bypass on some LEDs
- Higher risk of glow/flicker — document lamp brand/wattage
RFQ wording that helps factories quote correctly
“Neutral available: yes/no. Lamp type: LED xxW × n. Prefer neutral module if possible. If no-neutral, confirm bypass requirement and max LED count.” Attach a photo of the existing switch box when possible.
