GREENIE LIGHT-LIGHT



Greenie Light-Light, retail (priceless; as it is a homemade "one-off")
Manufactured by
Last updated 09-03-12







This is a homemade screw-in (medium base E-26) "light bulb" made by my best long-distance friend D.K.

It has an array of 25 brilliant true green LEDs, and operates from 110 volts to 130 volts AC 60Hz house current ("house current" is actually a misnomer; "current" has nothing whatsoever do with the voltage and frequency of household power when used in this context).

To use the Greenie Light-Light (yeah, like you're ever going to have one of these things!) just screw it into any medium screw base (E26 or E27) female light receptacle on a circuit that receives 110V to 130V AC 60Hz and then energise that receptacle (or "socket", which is acceptable in this context).

Do not under any circumstances operate the Greenie Light-Light on a circuit with a triac-based dimmer switch on it, whether that dimmer is on the wall or in the lamp itself -- the Greenie Light-Light will very probably overheat and fail rather quickly, and possibly quite specactularly as well!!! You don't want baby funnel web spiders, Mourningcloak butterfly caterpillars (larvae) or Stag Beetle grubs (larvae)...er...uh...I mean
YOU DON'T WANT AN UNWANTED FIRE!!!

(Edit:) From its maker comes the following text (no changes to spelling, grammar, or syntax were made; though none appear to have been necessary):

"Dear Craig Johnson,

The "Greenie Light-Light" is safe to use on dimmers. It is safe for itself, and it is safe for dimmers rated at least 600 watts. At least "fairly safe".

Maybe it won't dim well. My educated guess is that it will only start to dim when the dimmer setting is almost halfway down. And in the dimmer range's "lower half", I expect "Greenie Light-Light to be dimmed less than even dimmer-compatible CFLs, let alone incandescents.

That 33 ohm 5-watt resistor that is visible in one of the photos is a major reason why this thing is safe to use with dimmers rated at least 600 watts.

Maybe use of a dimmer can get that resistor burning-hot, but highly probably short of actual failure or starting a fire.

When I get it back, I can test it for usability with dimmers, including how hot that 33 ohm resistor gets.

As for LED burnout - I doubt touching exposed contact points is likely to do that. It appears to me that touching *within the LED array* is necessary to blow LEDs, and that does not look easy to me the way getting shocked looks easy to me."




The Greenie Light-Light is operated exclusively from 110V to 130V AC 60Hz, so I don't need to tell you which part to remove, huck into the forest with dozens of hungry skunks with overactive pissinary tracts and then rather emphactically tell you not to.



This is an LED light "bulb", not a flashlight meant to be thrashed, trashed, and abused. So I won't try to drown it in the cistern (toilet tank), bash it against a steel rod or against the concrete floor of a carport in effort to try and expose the bare Metalshinegreymon - er - the bare Metalblacktrailmon - um that's not it either...the bare Metalmegagallantmon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! - now I'm just making {vulgar slang term for caca} up!!!), let my mother's big dog's ghost, her kitties, my kitty or my sister's kitty cat piddle (uranate) on it, hose it down with my mother's gun, run over it with a 450lb Quickie Pulse 6 motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoñata, drop it down the top of Mt. Erupto (now I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. Therefore, this section of the laser's web page will seem a bit more bare than this section of the web page on a page about a flashlight.

This is also a loaner, and I'm sure it's owner would like it returned with no burned-out LEDs or the lingering odour of cat pee on it.

There are capacitors (or, "capacitators" or even "condensers") that can "bite" even when the Greenie Light-Light is turned off and unscrewed, so if you ever get ahold of it, you'll want to be aware of this. And you'll certainly never want to touch it when it is operating -- you may receive a very unpleasant surprise and possibly even blow out one or all LEDs if it is touched in the wrong place when it is energised in addition to the double-whammy of you getting zapped and possibly becoming worm food!

That dark spot at left-center that queered the test is a defect in the instrument's CCD imager that I cannot compensate for.

TEST NOTES:
Test unit was loaned to me by D.K. from Philadelphia PA. USA on 08-31-12; it was made by him (for both his and his ex-boyfriend Rich's enjoyment) and therefore has sentimental value (and D.K. kindly requested that it needed to be returned for that reason!), so the dreadful, "" icon will be appended to its listings on this website at once -- denoting the fact that I no longer have the unit, and no comparisons or additional analyses can be performed on it.
