# sensor Tri-Proof Lights

On a [tri-proof light](https://www.xingguanglightingcn.com/en/glossary#tri-proof) the sensor saves less energy than it saves you from lights that never get switched off: warehouse aisles and cold-store airlocks burn around the clock. A 3–5 minute hold is enough — longer and it might as well be permanently on, shorter and the light goes out while people are still walking.

## Which step the option actually changes

An option leaves the light output alone and touches three things: when it comes on, how long it stays on, and whether it stays on when the mains drop. Whether it earns its price is a question about the site — who operates the switch, and whether anyone has to walk out during an outage — not about the fixture.

The cost that gets left out is wiring: a sensor or emergency fixture needs a permanent live plus a switched line (or an emergency supply line), and retrofitting an old circuit means new conduit. If the quote excludes that, the site adds it later — often at close to the price of the fixtures.

## When to add it and when not to

The case for adding it is specific: the fixtures sit at 2.5–4 m where nobody can reach them, the switch is inconvenient, or people have to find their way out during an outage. The case against is just as specific: 24-hour process lines, and sites that already run a central control system — a second layer of control only adds a failure point.

Emergency options carry one hard constraint: the duration and the emergency flux come from the fire code that applies at the site, not from the fixture wattage. Confirm the required duration and minimum [illuminance](https://www.xingguanglightingcn.com/en/glossary#illuminance) first, then size the battery — reverse the order and you buy a fixture that has emergency output but does not meet the requirement.

## Four things to verify before ordering

① Whether flux and efficacy are quoted for the complete fixture or the light source — a 10–15% difference that changes the fixture count. ② Whether colour temperature and CRI are measured or nominal values; mixed CCT within one batch is the most common arrival dispute. ③ Driver brand and model, plus its derating curve at high temperature — it is the only part that really sets life. ④ The mounting kit list: chain, bracket and anchors in the box, or the site stops for a day.
