30xLED LIGHT BULBS

30xLED Light Bubs, retail $9.75 Manufactured by (Unknown) for Don's Green Store (Business has gone down the tube)
Last updated 12-17-11




This is a 120 volt AC lamp with a medium screw base that fits into pretty much any United States household light receptacle where an incandescent or compact fluorescent light bulb currently resides.

These bulbs cannot be used on a dimmer circuit, so please don't screw one of these in a dimming receptacle, or you might let out all of the magic smoke, or even cause the bulb to overheat and break or start a fire. And you don't want baby centipedes or cockroach egg cases...er...uh...AN UNWANTED FIRE.

I believe this bulb is designed to replace spotlight bulbs in fixtures designed to accomodate them. But you can use it in any 120 volts AC fixture, as long as you can deal with the spot the unlensed bulb produces - the lensed bulb produces more of a floody beam. The unlensed bulb can be used as an over-the-shoulder reading light.


SIZE



To use this bulb, just find a fixture you want to use it in, unscrew and throw the old bulb (love to hear those things pop!!!), and screw this bulb into the socket in its place. If you're adverse to breaking things, gently place the old bulb on a washrag or something in a drawer full of really soft fuzzy things.



Since this bulb was designed exclusively to be powered by 110-120VAC, this section can and will be skipped.

Since these bulbs were meant to be screwed in a light receptacle and not abused, I won't whap them against a steel rod, throw them in a toilet bowl, stomp on them, run over them, or inflict other punishments upon them that might be inflicted upon regular flashlights. So this section will be rather short.

One of the bulbs is made primarily of glass; the other is of mostly plastic construction. So they CAN become broken if dropped, thrown, or otherwise abused.
Handle them as you would ordinary household light bulbs, and they shouldn't give you any guff.

The beam that comes out of the unlensed bulb is a slightly warmish white, and shows no rings, blotches, or other artifacts that might be present in a product using a much lesser number of LEDs. The lensed bulb has a significantly wider beam; also relatively free of artifacts.

***VERY IMPORTANT!!!*** DO NOT under any circumstances screw these bulbs into a fixture controlled by a dimmer switch, whether that switch is on the wall or on the fixture itself. They WILL fail fairly quickly, and possibly quite spectacularly so, if this is done.
You don't want rats or silverfish...I mean...you don't want an unwanted fire.

TEST NOTES:
Test units of these bulbs (two units) were sent by D.P. of Don's Green Store and were received on the afternoon of 08-25-06.

Products were made in China. A product's country of origin really does matter to some people, which is why I published it on this web page.
