This Energizer RCL1NM2WR Rechargeable LED Flashlight can operate in two modes: - In 'ON' or 'high-beam' mode, it projects a bright focused beam, which forms a circle of 3 ft diameter from a distance of 12 ft away. The light pattern is very similar to that from my Rayovac BRSLED2AA-B 2AA LED Flashlight, except the output from this Energizer flashlight is at least twice as bright when it is freshly charged. - In 'nightlight' or 'low-beam' mode, the light is much dimmer, while the battery life is extended to 15 hours, instead of just 2-3 hours in full-power mode. To use it as an emergency power failure light, you should leave this flashlight in 'ON' position, and plug it into an AC outlet. The light goes out while it is being recharged. But when the power goes out, or when you unplug it from the outlet, the light comes back on immediately. You can also leave the unit in 'nightlight' mode while it is being recharged. But in this case, the flashlight remains on 24 hours a day since there is no light sensor. The light is actually too bright when used in bedroom. But it is just perfect for basement or hallways where you always need some illumination. Plus you'll never have to search for a flashlight again. Some other points that I like: - Unlike many other power failure lights, this one does NOT cover both AC outlets when it is plugged in. - It can be mounted in either up or down directions. - It only consumes 1W when recharging in nightlight mode. There is one thing I don't quite understand: The flashlight is powered by a single NiMH button cell, Varta CP300H, with capacity of only 300mAh. It seems to me there is enough space to fit an AAA NiMH cell with capacity of 800+ mAh, or even an AA NiMH cell with capacity of 2000+ mAh. By doing this, the battery run time will be extended by several folds. But more importantly, I will be able to swap in alkaline cells when the rechargeable battery runs out! On the other hand, the main purpose of this flashlight is just to help me find my other flashlights in case of a blackout. So for that I'm completely satisfied.
