Flashes and on-camera lights with case

Case / bag

— the presence of a bag or cover in the standard configuration of the lighting device. Bags are often equipped with handles or a strap for easy carrying, a cover is somewhat simpler - it does not have handles and is designed to be carried in a bag for photographic equipment, a backpack, etc. A bag or cover protects the device from dust and other contaminants, to some extent protects the contents from damage from impacts and falls.
