Big brother eliminates the incandescent bulb

That's great!

A twist on a liberal brainstorm -- usually it's the left that enjoys playing word games.

Case in point: Investment = spending ......

It is believed that fluorescent bulbs will not be the way of the future according to some in the lighting field. Shortly, there will be a replacement LED for your tungstun bulbs. Replacement costs are estimated to be $60.00 per bulb at an energy savings of roughly 80% electrical usage and last a stated 18 years at 18 hours per day. Said price is said to drop when used on a massive scale.

$60 bucks each. Hmmm..... multiple thousands of dollars to replace them in the standard fixtures of my home. Hmmmm!

I have a couple LED flashlights ... and the light output in unbelievable. Hardly uses batteries either, once the Huang Guangazou LTD ones are tossed in the trash ...

I can't figure out why they haven't invested in those, rather than push CFL's on the masses. Must've had a stockpile of components they needed to get rid of ...... or ..... the industry donated heavily to the Obama campaign .... hmmmmmmmmmmm ..... Makes absolutely no sense whatsoever.

I also have an LED strip in the barn over my workbench where I do all my carburetor work. It's like having your own personal sun right where you need it. Cost $50 though ...

My first foray into the LED realm was with a Kuryakyn Panacea light system for my Harley. I saw how the low current draw affected the turnsignal flasher, necessitating a resistor to put a load on the system & get the flasher working normally again (thinks a bulbs burned out, so flashes too fast). Sort of a wasted benefit there, as all the energy you just saved is being turned to heat needlessly ... but they look great, & they keep that *censored* in the BMW awake as I approach a stop sign.

I believe there are already LED replacements for various size and shape tungsten lamps. There are also LED replacements for 4 foot linear fluorescent tubes that run straight off the 120v supply and eliminate the ballast entirely.

LED technology is advancing rapidly and the lumens per watt of LED is on par with the best fluorescents now or even better. Unfortunately, "good" and "cheap" are still pretty far apart. The current crop of LED replacement lamps typically use inferior LEDs and overdrive them to get decent light output. This results in poor lumen maintenance.

"White" LEDs aren't really white. They actually operate on the same basic principle as fluorescents. The LED chip generates UV light which then excites a phosphor blend that creates the actual visible light out of red, green, and blue phosphors. However, due to the tiny size of the LED, the phosphors are driven very hard and operate at high temperatures, even with proper heat sinking of the LED chip, which is not a trivial task. Overdriving the LED or the use of poor quality chips ends up with light output declining very quickly. Yes, the LED may still be producing some sort of light still at 50,000 hours, but it may only be 20% of initial lumens.

Philips/Lumileds and Cree are probably the two biggest producers of "cutting edge" LEDs, although there are several others. Over the past several years, LEDs have been introduced that produce over 100 lumens/watt and also have color temperatures that are more suitable for home lighting rather than the bluish "daylight" color that looks rather ghastly when used in normal living spaces.

I'm not sure I agree with the whole mercury "shift" standpoint. While Home Depot and such may recycle them for free, I'm betting 95% of homeowners just toss them in the trash rather than be bothered to take them somewhere for recycling. Furthermore, I can only imagine the pollution being caused by the manufacture of the lamps in China. I remember seeing a picture on the web of a worker picking over a huge pile of broken twist lamps at a factory somewhere over there. I swear he was barefoot, too, but I don't recall exactly.

hmmmmm indeed! after getting bitten by the obsessive collector bug, i spent oodles on the other end of the game...

they are just a joy to use too... albit needing care and attention.

P.S. they emit approx 60watts of lite and 2500 btu's !!!

outdoor ding is fun! and gives al gore a warming theory!!

newer led technology available also!

Ooohh, Aladdin lamps are awesome! I've had my Genie II model for over 20 years now!

Unfortunately, they use oil (kerosene) to make light. I don't think they will work on biodiesel - too thick. I don't know what "coal oil" used to be, but maybe someday we'll have homes lit with Aladdin lamps and coal oil, just like the turn of the century!

we gotta watch those green police tho...

Just when I thought I saw it all..lol It's cool, I have been buying them up for a couple of years now. I'll bet it could pay off better than the market..
