The Multicolor 20 LED Fairy Lights is a battery-powered set of LED holiday lights that feature 20 5mm LEDs with inverse conical lenses on a cord attached to a box containing three AA cells and a slide switch that turns them on in steady mode, in unison blink mode, and off.

Feed the lights first (see directly below), and then you can go decorate that porch.

String these up as you would ordinary (corded) seasonal lights. Hang them on porches, mantles, doorways, or other places where you might normally hang light sets.

To turn them on, slide that little black switch on the upper-right side of the battery box toward the "on" legend (all the way right -- as far as it will go).

To turn them on in "blink" mode, slide the switch to the center position.

To turn them off, slide the switch to the "off" position (all the way to the left).



To change the batteries, slide the battery door off in the direction of the embossed label on it, carry it to a bridge over deep water (the Oakland Bay Bridge would be ideal; however, the Juneau-Douglas Bridge would also do in a pinch here), and throw it over the side so that it goes "blub blub blub" all the way to the bottom of Gastineau Channel with all of the bowling balls that were lobbed over that bridge in the 1950s and 1960s...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

If necessary, remove and dispose of or recycle the three used AA cells from the compartment.

Insert three new AA cells in the compartment, orienting each cell so its flat-end (-) negative faces a spring for it in each chamber.

Slide the battery door back on, and be done with it.
Aren't you glad that you didn't throw that battery door over the side of the Juneau-Douglas Bridge now?


This is what the Juneau-Douglas Bridge looks like...or what it lookED like anyway before it was replaced in 1976.


And this is what the bridge looks like now.


Current usage measures 123.40mA on my DMM's 400mA scale.
This equates to just 6.170mA per LED.



These light sets appear at least *reasonably* durable, in that they should not just fall apart on their own or through just casual handling.

This product is meant to be used as a seasonal light string (or for parties, weddings, and other festive occasions), not as a flashlight meant to be carried around, thrashed, used, and abused; so I won't try to flush them down the toilet, bash them against the concrete floor of a patio or a steel rod, let our household's five kitty cats uranate (go to the litterbox) on them, run over them with a 450lb Quickie Pulse 6 (motorised wheelchair), or perform other indecencies on them that a regular flashlight might have to go through.

The LEDs aren't dome-shaped like you'd expect; instead, the lenses on them have a reverse conical shape moulded into them - this helps the lights to be visible at much greater viewing angles than a standard dome-shaped LED would allow.
