The R-PAL is a compact lantern made by RTG, Inc. that is smaller, lighter, and brighter than any other lantern on the market. It utilizes a custom made integrated circuit, made by the same company, allowing it to provide a feature set unparalleled by any other manufacturer. There are 15 logarithmic brightness settings, covering a brightness range from 3 to 300 lumens. When using the flashing or sos modes, the lantern gains even longer runtimes (the lantern can use all 15 brightness settings in any mode). The mode and brightness are retained between on/off cycles, and there is no need to cycle through anything. The R-PAL also has an automatic shut off feature, where it will warn the user (through a unique strobe pattern) and then turn itself off. There is also a low battery indicator, also displayed through a unique strobe pattern.
