Last updated 02-02-22
Tired of getting out the Christmas lights every year and finding they don't work because half of the blubs are busted?
Tired of the endless chore of hunting down & changing bulbs as they go out over the duration of the holidays?
Do you live in California or Washington and pay so much for power you can no longer afford to put up lights anymore?
Than this light set is for you.
The Battery-Operated Spider Cap Twinkle Light String is a set of battery-powered LED Christmas lights that are cheery and colorful.
This light set has 10 T1¾ (5mm) purple (bicolor red and blue) and orange diffused LEDs with cute "spider" bulb caps, operates from two (2) AA cells, and has black insulated wire.
Although labelled for indoor use, I believe you can safely ("safely" NOT in an electric shock risk here; I mean safety of the light set itself in this context. You certainly won't get zapped on the meager 3 volts that this set uses!!!) use the set outdoors in a covered area (such as on a porch) where rain or snow cannot fall directly or indirectly on the battery box. The LEDs themselves appear to have at least light to moderate protection against rain or snow ingress.
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.
Or just hang the suckers off your dorm room ceiling for that special holiday feeling all year 'round.
To turn them on, slide the black slide switch on the battery box to the right until it clicks once to turn them on in "twinkle" mode (where the LEDs alternately flash on and off at a rate of approx. 1.8Hz). Slide it some more to turn them on in continuous mode (all lamps in the set come on).
To neutralise them when you are finished using them, slide the switch to the leftmost position.
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 the two used AA cells from the compartment as you see fit (or recycle them if your community has a battery reclamation program in place).
Insert two 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?
Current usage measures 65.10mA on my DMM's 200mA scale.

These light sets appear at least *reasonably* durable (except for the battery box; which has a chintzy, brittle, cheap feel to it like many products of "Hoo Phlung Pu" origin {often made by underpaid workers in perspiration shops} so often do), in that they should not just fall apart on their own or through just casual handling; though if the set is dropped from any significant height, that battery box may become busted.
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, trashed, and abused; so I won't try to drown them in my toilet (actually, I did -- see below for video!!!), bash them against the concrete floor of a patio or a steel rod, let my landlady's doggos pass micturition (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.
There is no evidence of PWM (Pulse Width Modulation) at least at low-AF (audio frequencies); however my oscillope was stolen from me in late-2018 so I am not equipped to test for the presence of PWM at higher frequencies.
Water-resistance appears to be higher than usual; just keep the battery box bone dry and you should be ok.
Does this evaluation look an awful lot like this one?
Thought that you'd say so.
That's because these lights are electrically (and somewhat optically) similar to that set, so I was able to use its eval. as a template for this one.

Spectrographic analysis of one of the orange LEDs in this light set.
This appears to be a phophor orange LED; this is evident because of the unusually broadband emission.
Spectrographic analysis of one of the orange LEDs in this light set; spectrometer's response narrowed to a band between 615nm and 635nm to pinpoint emission peak wavelength, which is 629.00nm.

Spectrographic analysis of one of the bicolor purple LEDs in this light set; spectrometer's response narrowed to a band between 435nm and 455nm to pinpoint blue LED emission peak wavelength, which is 442.700nm.
Spectrographic analysis of one of the bicolor purple LEDs in this light set; spectrometer's response narrowed to a band between 650nm and 670nm to pinpoint red LED emission peak wavelength, which is 659.350nm.
