Are Explosion-Proof Lights Afraid of High Temperatures

In fact, the heat resistance of explosion-proof lights has its limits. For instance, if a light’s casing can withstand temperatures up to 135°C, does that mean it can tolerate high heat? That’s not necessarily true because the solder inside the light beads has a much lower temperature tolerance. If the temperature exceeds 100°C, the beads might fall off. Therefore, the casing temperature does not represent the internal temperature of the light, which is typically around 80°C.

In high-temperature environments like boiler rooms and paint baking rooms, boiler rooms generally don’t pose a problem, but paint baking rooms are definitely unsuitable.
