It got the best of me so I went and bought the darn thing. This is a description, straight from the CCrane web page.

"Many of our customers tell us they use our LED flashlights to read at night. We love the soft, bluish, healthy feeling, glare-free light of the white LEDs. We now have a light bulb with 20-LEDs that will fit in a regular 120 Volt lamp. It is best suited for a light fixture where light can be directed like a reading lamp.
All 20 LEDs only draw 4 watts of power! This may be the first heirloom electric light bulb simply because it will last so long it will probably be passed down from generation to generation. Waterproof with a standard bulb base. Size: 2-1/2" W x 3" L."

The price was $59.95, supposedly a ten dollar discount according to the web page. The lamp arrived in a plastic bag with a sheet of paper that says the manufacturer is Dana Lighting, a division of Catalina Lighting Inc. and they give an address in Eaton, Mass.

The construction of the bulb is very solid. The head is perhaps a shade bigger in diameter then a regular lightbulb. The 20 LEDs appear to be randomly scattered and solidly epoxyed in place. It does indeed look waterproof. So I put the bulb in one of those swing arm desk lamps and fired it up. As you all know how LEDs operate, you do want to put the bulb in a lamp where the head of the bulb is directly facing forward and not bouncing the light off of a reflector in which some of the lamps do.

I was not very impressed with the light output. Unfortunately I only have a 7 LED Trek light to compare it to as far as multi-LED lights go. While the total light output of the bulb is considerably brighter then the Trek, looking straight at the LEDs the Trek definitely drives them quite a bit harder. I would think that without battery considerations to deal with, you would want to drive those LEDs just as hard as they can take it but I don't believe this is the case with this bulb.

So as a reading lamp? Yeah I guess so but you have to have the light pretty much right on top of the reading material and the area of coverage is not that great. If you were reading a fairly good size magazine, you would have to move the magazine around as you read to keep in in the center of the light. It might also work as a less intrusive alternative should you have a significant other lying next to you, but it's not nearly bright enough for me to replace my regular 60W incadescent lamp for every night reading purposes while lying in bed.

I'm not sure if I'm going to return it or not but I wouldn't buy it again. What I would like to do is put it in the outside light by the stoop of my door. I would leave it on 24 hours and it should throw enough light so that you wouldn't have to fumble with a keychain light to unlock the door in the dark. I say I would like to but I probably won't because I don't want anybody stealing my $60 light bulb.
 
I hear you....but how many people would have a clue that that dim bulb by your door would be worth $60

You might be surprised.
I've had a white LED anchor light on the end of a thin pole on my wheelchair for about a month, and the stick is busted in four places already from people trying to make off with the thing. :-(
 
For reading in bed with the least disturbance to others, I like the Eternalight. I am amazed at the amount of light it gives out for its size and number of LEDs.

Unless prices become more reasonable, to me compact fluorescent bulbs make more sense...

For this task I take one of my headlamps.

I agree but they interfere with am radio reception which I often listen to at the same time.
 
I hate flourescent lights. They make me depressed

I feel like I am in a supermarket or an office.
 
actually a good compact fluorescent puts out very similar light to an incandescent.
 
I hate to say it, but I'm not too big of a fan of fluorescent bulbs either and not just for the reasons that most people don't like fluorescent. This may sound strange to those that don't experience this effect from fluorescents, but I've got very sensitive hearing and the hum that the transformers that fluorescent bulbs use drives me nuts. Even the transformers that are more quiet than normal are obnoxiously annoying to me when everything gets really quiet at night. I guess I'm just overly sensitive to sound pollution because I'm one of the few people that I know of that has spent nearly a hundred dollars in sound dampening my computer case (of course now that I've learned a few tricks I could do it for a fraction of that cost). Also I agree with everyone else about transformers in fluorescents ruining radio (AM & FM) and TV reception. I used to have a fluorescent bulb in my bedroom until I discovered that it was completely ruining my reception of channel 5 and then it had to go. And I thought the FCC was supposed to force them to shield these things better than this. I suppose the FCC doesn't have anything better to do with all of our government money (and there is a LOT of it) than to harass harmless pirate radio stations and to make stupid rules that hold back HDTV technology more than 10 years behind the rest of the world.

Do you have a web site on this stuff (or any links)???

I'm not sure what the sound you're hearing could be... the only thing I hear in these types of stores is that damn bell that keeps going "ding...... ding, ding" every freakin' two minutes.
After half an hour in there, I just want to rip the thing off the wall and stomp on it.

also color TVs used to make a very high pitched sound - a vibration that could be fixed by sticking toothpicks in the copper windings - but I don't hear the TV noise much anymore - maybe it's the new TVs, maybe I'm losing my hearing?<HR></BLOCKQUOTE>

This sound is the 15,575.0Hz signal from the horizontal output oscillator. This already strong signal is fed to a coil on the yoke to provide horizontal deflection; it also further amplified and fed to the flyback coil, which provides the 25KV+ needed by the 2nd anode on the CRT (picture tube).

The usual source for the sound itself in most TV sets & computer monitors is the flyback coil. Although most modern flybacks use a powdered ferrite core, there is a retaining rod that encircles the core on many of these, and (in most cases,) that's what's vibrating. A shim or two, gently but firmly jammed into the right section and glued into place, should silence these.
Plastic shims would be preferred, but DRY balsa or other wood could be used temporarily.

Those flybacks which have any discrete laminations whatsoever tend to be the worst offenders, as the thin metal sheets bang into one another at 15.575KHz.

If there are any small transformers between the horizontal output transistor and the yoke, one of those could also be buzzing at 15.575KHz and need to be silenced (ie. silicone sealant, insulating shims, or similar treatments).
 
Harrkev: In response to your question of whether I had more info on quieting your PC, I started a new topic in the Chit Chat section which can be found here. I thought it inappropriate to put such a long and off topic response here in this topic. I hope everyone that is interested in quieting their PC's will take a moment and check it out because a great deal of research and time went into collecting this information and I would like to know that others can benefit from it as much as I have.
 
Ted the Led: Thanks for the info about the Philips line of compact fluorescents. I will have to give it a try sometime because I like the bright white light that fluorescents put out and the high efficiency, it's just the noise and RF pollution that I hate so much.

--me too. I have had good experience with the Philips line of compact fluorescents, though. Check out the 'Earthlights' (but not in the 'daylight' version, get the indoor (more yellow-warmer) with the dome covers (like the outdoor ones also have) - the globe/dome disperses the light better , and so is less glaring..also the 'Earthlights' don't die when the voltage drops during brown/black outs - like the others do, eventually..they claim to be rf interference free and I have noticed no radio interference from them either. I got them at Sears..
