Plastic-body industrial flashlights insulate against heat, so they won't become too hot to hold in high-temperature environments. They won't conduct electricity like aluminum flashlights and are more resistant to impacts, scratches, chemicals, and water, but they may burn out when run for extended periods. Plastic flashlights are commonly used by electricians, firefighters, plumbers, and others working near electricity, in hot workspaces, or in wet locations. They are powered by disposable batteries.
