Last updated 01-29-22





I found this light set at Right Aid for 50% off, and being the LED nerd that I am, I *HAD* to have them.

The light sets contain 50 multicolor (10 ea. phosphor red, phosphor yellow, phosphor green, phosphor purple, and native blue) "blob-type" LEDs, powered by three AA cells inside a surprisingly well-constructed battery pack.

They can be set to all operate continuously or be operated in any of eight other modes including a mode which is audio- (sound-) sensitive.

Lighted length is advertised as 15.80 feet.

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

String these up as you would oridinary (corded) seasonal lights, but handle them somewhat gingerly because the wires are just a wee bit thinner than the wires are on corded sets. Hang them on porches, mantles, doorways, or other places where you might normally hang light sets -- or just hang the suckers off your dorm room ceiling for that special holiday feel all year 'round.

To turn them on, press & release the rubbery black button on the battery box. To change modes, quickly press & release the button one or more times until the desired mode comes up.

To neutralise them when you are finished using them, press & release the button one or more times until they extinguish.

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.

Sound Sync mode does ***NOT*** operate on this timer; the lights will remain on until you manually neutralise them.



To change the batteries, unclip the two clips on the battery door and swing the door open. It is captive, so nothing is going to fall off, go into the rug, and later fall prey to the hungry, hungry vaccum cleaner.

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.

Swing the battery door back closed, and snap the two clasps back into place.

Current usage measures a modest 37.80mA (in "steady-on" mode) on my DMM's 200mA scale.
In sound synch mode, the quiescent current (when no sound ia being detected) is 5.24mA; all LEDs are dimly illuminated in this state.



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 outdoors because they are immune to $#¡77Y weather but I don't believe that they're totally submersible), 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 dalmations go poddy 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.

Judging by the construction of the battery/electronics housing, these lights are weatherproof at minimum.
There's a surprisingly beefy rubber gasket around the entire edge of the case and the power/function button is totally inside the case but a circular rubber cap allows you to actuate it without actually exposing it to the elements.

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

This also allows the manufacturer to connect all of the LEDs in parallel with one another; something that cannot be easily done when mixing original chemistry (GaAlAs) reds and GaN blue & green LEDs without additional support components; this helps to keep the cost down.

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 those tiny little batteries (when three AA cells are called upon to illuminate 50 LEDs, yeah I'd call them "tiny" hahaha!!!)

I'm not sure just where the mic (the standard industry abbreviation for, "microphone") is, so please don't ask.

I took note that one of the LEDs was inoperative a few hours after I hung the lights on our porch; I don't know if it went out while it was outside or of it was defective right from the get-go. Since I do not have this data available, I'm not going to punish the light set by immediately whacking off stars -- it seems only fair that I give the benefit of the doubt in this case.

I was unable to obtain a viable spectrum of the native blue band because the phosphor emission was "stepping on" it.

The purple color is a bit sickly; it reminds me of the phosphor purple LEDs in the Purple Mini LED Light Set which (to me anyway) were extremely bluish.

A video on YourTube the 50xLED Battery Operated Sound Synch Wire Lights being cycled through their modes (set to the song, "Rudolph the Red-Nosed Reindeer") and responding to music from the Commodore Amiga computer demo, "äMPäri3" by the Amiga demo group Dekadence.



A video on YourTube showing the 50xLED Battery Operated Sound Synch Wire Lights deployed on our front porch.
They were set to "Timer -- In Waves" for this video; they're the brightest lights in this video.

That music that you hear is part of the song, "Snow Miser / Heat Miser" from the 1970s TV special, "The Year Without a Santa Clause".

The video loops twice in order to accommodate the length of the music.




TEST NOTES:
Test unit was purchased at a Right Aid store in Fresno CA. USA on 12-01-20.


UPDATE: 01-29-22
I inadvertently got my wheelchair snagged in the lights the day before yesterday, and the following photograph shows the results of my "handiwork":


There are approx. 15 LEDs still attached to the controller that still function properly, but the majority of them were busted off.

Because the light set is still PARTIALLY functional, I'm going to deploy the, "" icon to its listings on this website; this indicates that the product has been damaged, but that (what remains of it) still works.
