У ствари, отпорност на топлоту сијалица отпорних на експлозију има своје границе. На пример, if a light’s casing can withstand temperatures up to 135°C, да ли то значи да може да толерише велику топлоту? That’s not necessarily true because the solder inside the light beads has a much lower temperature tolerance. Ако је температура exceeds 100°C, the beads might fall off. Стога, 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.
