Sa totoo lang, ang heat resistance ng explosion-proof na mga ilaw ay may mga limitasyon. Halimbawa, if a light’s casing can withstand temperatures up to 135°C, ibig sabihin kaya nitong tiisin ang mataas na init? That’s not necessarily true because the solder inside the light beads has a much lower temperature tolerance. Kung ang temperatura exceeds 100°C, the beads might fall off. Samakatuwid, 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.
