What is a hand lamp and what should be its voltage rating in confined space?

A hand lamp, often referred to as a portable work light or flashlight, is a lighting device designed for use in various settings, including confined spaces. In confined spaces, the voltage rating of a hand lamp should typically be low, often around 12 volts or less, to minimize the risk of electric shock and ensure safety in potentially hazardous environments. Additionally, the lamp should be intrinsically safe or explosion-proof, depending on the specific conditions of the confined space.
