Fil-fatt, ir-reżistenza tas-sħana tad-dwal kontra l-isplużjoni għandha l-limiti tagħha. Per eżempju, if a light’s casing can withstand temperatures up to 135°C, dan ifisser li jista 'jittollera sħana għolja? That’s not necessarily true because the solder inside the light beads has a much lower temperature tolerance. Jekk il- temperatura exceeds 100°C, the beads might fall off. Għalhekk, 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.
