Re: USO digital illumination is it better ?
The new digital rheostat is a huge upgrade from the original design. The brightness is about the same on the top end, but it has more steps in the range. The biggest improvements are, longer battery life, about 100 hours on the brightest setting, water proof to 66 feet, auto shut off after one hour, and a memory. The memory works like this; when you turn on the unit and set it to a desired setting, then turn it off, when you turn it back on it will be at the last setting.
Hope that helps!
