Saving energy LED bulb light

LEDs aren't quite as green as we think:

I keep looking for RF bulbs to come out. Conventional tungsten filament bulbs put out about 15 lumen per watt LED at 70 Lumen per watt and RF at 140 lumen per watt.

Yes, but the "cell phones and wi-fi are gonna kill you" folks will try to get the RF technology banned.
Of course, as a HAM radio operator, I won't want them because of the interference they might cause :p

I've seen LED's pushed as a green alternative because they use less energy. I've never seen it advertised that they are safer to dispose of.


Seems like misdirection to me.

Nah,it's just a "half truth".

I expect that they'll be recycled like most any electronics can be these days.
I remember when people realized there was a minute amount of mercury in CFLs and started getting all bent out of shape and saying we should go back to incandescents. Then someone did the math an showed that the amount was many times less than a power plant would produce in generating the power difference between the two types. So, less carbon, and less mercury; Yay!

I did some poking around on the net and learned that a lot of mercury is released during a forest fire. More poking revealed that the mercury originated from burning coal, had just settled on the trees, and was re-released during a fire.

All said, we're not taking very good care of the only rock we have.

if people are so afraid of mercury then why were they putting it in their mouths under their arms and even up their bums All in the form of thermometers you don't see those getting banned I think it should be a matter of preferance

I'm not sure that we're using many mercury based thermometers any longer. It's rare to see a thermostat with a mercury switch in it any longer.

The problem will allowing people to "choose" is that they don't have the knowledge or education to appreciate the long term effects of their choices.

Just sayin.

Calif. (and I think the rest of the US) banned Hg in fever thermometers in the early 90's.

Can't speak for our northern neighbors, but there are none available except in legacy medicine cabinets these days.

Mercury thermometers and blood pressure cuffs have not been produced for some time. If you check your thermometer at home, if you still have a glass one, note it has a red alcohol measuring line now, not the hg of old. Bp cuffs, if not electronic are all dial or aneroid. Same for outdoor thermometers. No more hg. They are not banned, per say, but they are no longer sold in the us. Plus risk management doesnt want them around. After an accident in a school with a bp cuff several years ago that cost the district big bucks, as the safety director at my school i got rid of everything mercury. Even the science lab only has the "red line" thermometeres.

It's much to do about nothing. The incandescent bulb's extra share of the power plant exhaust has more pollutants in it than the LED bulb has. This includes scrubbed coal. Furthermore, the amount of nasties in a regular incandescent bulb with an edison base is quite high. That edison base has it's share of heavy metals. The thing is you will go through many times more of them than you would LED based bulbs. What about all that extra manufacturing materials, wastes, etc..
