Last updated 02-15-08

The 3in1 Power Failure Light is an LED nightlight that's about the size of a pack of cards, and performs three distinct functions: it acts as a nightlight, a power failure light, and a handheld rechargeable flashlight with a slightly adjustable focus.

It has a rechargeable battery and charger built in, and has three white LEDs: one for the flashlight, and two behind a prismatic plastic window that serve as a nightlight and the power failure light.


To use the 3in1, remove it from its package by cutting down one side and either the top or the bottom with household scissors; or a sharp knife or razor blade if scissors are not available.

Unfold the AC prongs from the underside, and plug it in to any standard United States 110-130 volts AC household receptacle. A red LED on the front of the unit should now come on; I believe this indicates either charging status, or that the unit is receiving power. It's too early to tell exactly *WHAT* the red LED indicates at this point.

If the switch on the side is set to "NITELITE & EMERGENCY LITE", the two white LEDs on the front of the unit will come on when power to the unit fails or is interrupted.

And if the switch is set to "FLASH LITE", the flashlight on the top of the unit can be used. You can unplug the unit and fold the AC prongs on the bottom of the unit into slots that fit them. So you can carry it in a pocket or purse if desired, and not have two metal prongs poking you or otherwise getting in the way.

The focus (beam width) of the flashlight can be somewhat adjusted by turning the plastic ring that holds the lens.

Because this product uses an internal rechargeable battery and internal charger that plugs into any household 110-130 volts AC outlet (United States), this section can and will be skipped.

This is a nightlight designed to be plugged in somewhere and not {vulgar term for having had intercourse} with very often, not a flashlight designed to be used every day and thrashed and abused, so I won' try to drown it in the toilet, smash it against a concrete sidewalk, throw it against a wall, stomp on it, sit down hard on it, or otherwise abuse it. So this portion of the web page will be more bare than this section of the web page on a page about a flashlight who's sole purpose in life is to be a flashlight.

The unit has a CdS (cadmium sulfide) photocell in it so the nightlight turns on at dusk and turns off at dawn all by itself - no switches to fuss with or forget.

A red LED on the front of the unit stays lit to indicate the unit is receiving power; do not expect it to go off or be able to turn it off without unplugging the entire unit.

Measures 6,040mcd on a Meterman LM631 light meter.
Flashlight has a wide beam angle, which translates into a lower intensity reading.
