Multicolor 3-Function 18-LED Ultra-Slim Wire Light Set, retail $3.88 (walmart.com...
Manufactured by (Unknown) for Wall*Mart (www.wallmart.com)
Last updated 06-07-21





These light sets were found in a Wall*Mart store in the western coast of the United States (the state of California, to be specific) in early-November 2019 for $3.88 each.

The light sets contain 18 (eighteen) "blob-type" phosphor multicolored LEDs (yes, even the green and blue LEDs are phosphor-type!), powered by three AA cells inside a decently-made battery pack.

The green and blue lights have a whitish, pastel coloration to them that some people may find exceedingly pleasant when compared to the sharper spectral blue and green that most other LED light sets produce.

They can be set to all operate continuously, blink in unison, or fade on & off in unison.
The lights also have an inbuilt timer that turns them on for six hours and off for eighteen hours.

Total set length is advertised to be 7 feet; lighted length is advertised as 6 feet.


 SIZE



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, but handle them carefully because the wires are considerably thinner than the wires are on corded sets. Hang them on porches, mantles, doorways, or other places where you might normally hang light sets.

To turn them on, slide the black slide switch on the battery box to the left until it clicks once to turn them on in steady-on mode. Keep sliding the switch to the left until it clicks again to turn them on in blink mode, Keep sliding the switch to the left until it clicks again to turn them on in fade mode.

To neutralise them when you are finished using them, slide the switch all the way to the right until it stops.

The light set has a 6-hours on / 18-hours off automatic timer; simply meaning that you can just "set it and forget it" to borrow a phrase from one of Ron Popiel's infomercials that ran near the turn of the century.



To change the batteries, slide the battery door off in the direction of the arrow embossed onto it, and carefully place it on the floor directly in front of the fireplace so that Santa Clause will slip on it and fall when he comes down the chimney to deliver presents on Christmas morning...O WAIT!!! THAT'S A REALLY $#¡77Y IDEA!!!
Just set the damn thing aside instead.

If necessary, remove and dispose of or recycle the 3 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 leave it in front of the fireplace where a Christmas accident could occur now?



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 Christmas light string in a reasonably dry area indoors or in a covered location outdoors, not as a flashlight meant to be carried around, thrashed, used, and abused; so I won't try to drown them in my toilet, bash them against the concrete floor of a patio or a steel rod, let my landlady's puppies and adult doggos uranate (piddle) on them, run over them with a 450lb Quickie Pulse 6 (motorised wheelchair), or perform other indecencies that a regular flashlight might have to go through.

This light set appears to use ALL PHOSPHOR LEDs -- that tells me at once that blue LEDs are now cheaper to manufacture than red, yellow, and yellow-green LEDs!

One thing I did note is that steady-on really isn't "steady"; no, the LEDs blink rapidly enough to appear steady-on but if you sweep your eyes across them you'll see them blink. This is because the "steady-on" mode uses PWM (Pulse Width Modulation) to help extend the life of the batteries.

It isn't quite as greenish as this photo makes it appear; I don't have Photoshop so I am not able to "doctor" the image up to show a truer color. I attempted to use IrFanView but I met with only limited success; the original photograph is directly below.

Video on YourTube allowing you to see the 3-Function 18-LED Ultra-Slim Wire Light Set blinking on the bed while I'm changing the functions (I haven't yet chosen a location in which to hang these).

O BOY!!! Some blinking lights! So thrilling!! So heart-stopping!!!
Actually, it kinda makes you want to "nock" "uh" "reeth" "oph" "uh" "dore" "ahnd" "thenh" "pruseed" "tu" "bete" "thuh" "liveng" "tweadel" "owt" "uv" "itt" "whithe" "thuh" "handel" "uv" "ahn" "olld" "orr" "yoozed" "snoe" "shuvil" doesn't it? ;-)

That music that you hear is the song, "Snow Miser - Heat Miser" from the 1970s TV special, "The Year Without a Santa Clause".
This product is not audio (sound)-sensitive in any manner; the music may safely be ignored or even muted if it piddles you off.

The video was allowed to loop several times in order to accommodate the length of the song.



TEST NOTES:
Test unit was purchased at a local Wall*Mart on 10-03-19.


UPDATE: 11-13-19
I like these lights so much so that I snagged a second set.


UPDATE: 11-14-19
I like these lights so much so that I snagged a third set; I'll likely use them to brighten up my wheelchair.


UPDATE: 11-22-19
From BigClive comes the following juicy tidbit that I'd never even considered (no changes to grammar or syntax were made; none were actually necessary):

"The use of blue LEDs and phosphor is partly so all the LEDs have a matched voltage for parallel use and also because the red and yellow phosphors are brighter than traditional red and yellow LEDs."
