Flashing LED "Toad" Jelly Finger Ring, retail $1.16
Manufactured by (Unknown) for Right Aid (www.rightaid.com)
Last updated 02-20-13

This is a nice looking finger ring with three LEDs and a strobe circuit inside. The ring is made of a very soft and flexible rubber-like material, which will not cause any additional damage if you try to give somebody a knuckle sandwich while this ring is on.

The ring portion (the part that fits your finger) should stretch to accomodate most any finger diameter.

It appears to be disposable; there does not appear to be any way to change the batteries in it.


Place the ring on your finger much like you'd put any other ring on. If the bottom of the ring becomes twisted, just use your other hand to untwist it.

Press down on the ring and then release it to turn the LEDs on. It automatically turns off after 22 seconds (timed on a clock with a second hand on it). Yes, it really is as easy as that.

This ring appears to be disposable; there is no obvious way to change the batteries in it when they poop out. So this section of the web page will not be necessary.

This was intended to be a disposable product, so even if you do manage to break it, just throw it away and go get another one. At $1.16 apiece, it certainly won't break the bank.

And at $1.16 apiece, I was rather surprised to find it has a BLUE LED in it. I expected to find red LEDs in it, but when I turned it on before purchase, it was that blue LED that clinched the sale.

Because this is a disposable ring and not a flashlight meant to be thrashed and abused, I won't try to drown it in the toilet, smash it against a concrete sidewalk, throw it against a wall, stomp on it, sit down hard on it, or otherwise abuse it. So this portion of the web page will be more bare than this section of the web page on a page about a flashlight.

It feels somewhat constrictive on even my pinkie finger, unlike other "jelly" rings I have used in the past.

Spectrographic analysis
Spectrographic analysis of all three LEDs in this ring.
I was unable to take seperate spectra because the LEDs are heavily diffused by the ring's body and because of the high flash rate.

Spectrographic analysis
Spectrographic analysis of the red LED in this ring; spectrometer's response narrowed to a band between 630nm and 640nm to pinpoint peak wavelength, which is 633.987nm.

Spectrographic analysis
Spectrographic analysis of the yellow LED in this ring; spectrometer's response narrowed to a band between 590nm and 600nm to pinpoint peak wavelength, which is 592.555nm.

Spectrographic analysis
Spectrographic analysis of the blue LED in this ring; spectrometer's response narrowed to a band between 440nm and 450nm to pinpoint peak wavelength, which is 445.184nm.

Spectrographic analysis
Spectrographic analysis of the green phosphor emission of this ring when irradiated by its inbuilt LED; spectrometer's response narrowed to a band between 500nm and 520nm to pinpoint phosphor emission peak peak wavelength, which is 508.499nm.

Quite holiday-themed
Light weight despite being battery-operated
The price is right


Disposable -- that means three nice LEDs go down the {vulgar slang term for caca}bowl when the batteries go to pot
Feels a bit constrictive even on my smallest finger
