Lumens describe how much light is produced, not how usefully it is delivered. A focused 5W torch puts more light on a distant object than an unfocused 20W one, which is why adjustable focus appears on the higher output bodies rather than only the brightness figure. Beam pattern is stated where a torch is focusable rather than being inferred from the wattage.
Output across the range runs 50 lumens on a penlight up to 1200 lumens on the 10W rechargeable body, with 20W and 60W COB forms above. A penlight lights an engine bay at close range; a high output torch reaches across a yard. Wattage and lumens are both quoted because one describes what the torch draws and the other what it gives out.
Power source decides whether the torch is ready when it is picked up. A rechargeable torch is charged rather than restocked, and a USB-C body charges from anything to hand. A cell torch works the moment cells are fitted, which suits a torch used rarely. Runtime is also stated per torch, which is the other half of what a rechargeable body is judged on.
Specialist forms cover what a general torch cannot. A head or hat torch leaves both hands free, a UV penlight finds leak dye, and an intrinsically safe ATEX torch is rated for an atmosphere where a standard torch is not permitted.
