Compact safe light, which can be used to check prints in the developers, aperture settings of the enlarger, etc. Also very useful to check development progression of lith prints.
The red LEDs have a very tight spectrum and therefore the safe light torch is save for all black&white papers (not for panchromatic papers).
The torch is switched on by pressing and holding the red button. It uses a A23 battery. The battery lasts for 3000-5000 flashes of 3 second duration each.
