50xLED Battery Operated Mini Lights, retail $14.99
Manufactured by (Unknown) for Right Aid
Last updated 12-05-20
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 orange, phosphor green, phosphor purple, and native blue) 3mm through-hole LEDs, with inverse conical lenses powered by three C cells inside a surprisingly well-constructed battery pack.
They can be set to all operate continuously or be operated in any of seven other modes.
Lighted length is advertised as 12.10 feet (3.68M).

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.
A red LED turns on next to the printed mode name; this puts an end to guessing which mode you're in.

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.
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 C cells from the compartment.
Insert three new C 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 94.40mA (in "steady-on" mode) on my DMM's 200mA scale.
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 ORANGE, PHOSPHOR GREEN, and PHOSPHOR PURPLE LEDs -- that tells me at once that blue LEDs are now cheaper to manufacture than regular red, orange, 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 almost immediately 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.

Spectrographic analysis of the red LEDs in this light set.
Spectrographic analysis of the red LEDs in this light set; spectrometer's response narrowed to a band between 630nm and 660nm to pinpoint the peak phosphor emission wavelength, which is 642.570nm.
The native emission was too weak to be spectrographically resolved.

Spectrographic analysis of the orange LEDs in this light set.
Spectrographic analysis of the orange LEDs in this light set; spectrometer's response narrowed to a band between 600nm and 640nm to pinpoint the phosphor peak emission wavelength, which is 615.690nm.
Spectrographic analysis of the orange LEDs in this light set; spectrometer's response narrowed to a band between 465nm and 485nm to pinpoint the peak native emission wavelength, which is 475.430nm.

Spectrographic analysis of the green LEDs in this light set.
Spectrographic analysis of the green LEDs in this light set; spectrometer's response narrowed to a band between 500nm and 540nm to pinpoint the phosphor peak emission wavelength, which is 519.260nm.
I was unable to obtain a viable spectrum of the native blue band because the phosphor emission was "stepping on" it.

Spectrographic analysis of the purple LEDs in this light set.
Spectrographic analysis of the purple LEDs in this light set; spectrometer's response narrowed to a band between 625nm and 645nm to pinpoint the phosphor peak emission wavelength, which is 629.000nm.
Spectrographic analysis of the purple LEDs in this light set; spectrometer's response narrowed to a band between 440nm and 460nm to pinpoint the peak native emission wavelength, which is 448.350nm.

Spectrographic analysis of the blue LEDs in this light set.
Spectrographic analysis of the blue LEDs in this light set; spectrometer's response narrowed to a band between 445nm and 465nm to pinpoint the peak emission wavelength, which is 455.06nm.

A video on YourTube showing the 50xLED Battery Operated Mini Lights deployed on our front porch.
They were set to "In Waves" for this video; they're the brightest lights in this video.
That music that you hear is the song, "Snow Miser / Heat Miser" from the 1970s TV special, "The Year Without a Santa Clause".
The video loops three times in order to accommodate the length of the music.
