I'm engaged in LED Lighting for 2 years,and LED Lighting is new generation for all people it's said,but I notice there are very problems for LED lighting with cost and technology,as know,LED lighting mainly consists of LED Source,Power supply and AL heat-sink part etc,what is power supply's work life?AL alloy price is if reduced in the futuer? Looking forward to your reply.Thanks! Email:leeco2006@gmail.com

Mr. McGowan for such an esteemed position you should really watch what you say about LEDs. Yes LEDs are smaller but you DO have to worry about heat dissipation. In fact this is the primary cause of failure! The inability to 'wick' the heat away from the element and the circuitry. and yes lighting manufactures are redesigning luminaries but they have to be cognoscente of thermal dynamics of the LEDs. Plus it would have been nice if you would describe to folk about the difference of SMDs.

The "warmth" issue is taken care of with either the addition of some amber LEDs to the "cone", or by covering the outer surface with an amber coating. We have LED bulbs in our house that differ very little from an incandescent in terms of output color.
I hate LED lights. HATE HATE HATE 'em. I like the warmth that comes from incandescent lights and my halogen recessed lights. I like to see the snow melt from my mini lights on my Holly bushes @ Christmas. I also like the clear bulbs in my chandelier. Why not give people a frickin choice instead of more government intrusion into our lives.
@free2drm While I agree with "less government intrusion" and hate the idea of "banning" incandescent, we are actually experimenting with replacing some of our incandescent and halogen bulbs with LEDs and I can give you one example of how impressed we are: we have a "night light" above the kitchen sink that is super bright, yet we feel completely comfortable with leaving it on all day and night, it doesn't produce heat and doesn't suck too much power.
@free2drm You are deluded. Incandescent lights are not being banned. Your waterlogged mini-lights will not be taken away from you. You can even buy more, and watch them melt all the ice you want. What's happening is that minimum efficiency standards are being put into place for the most commonly used bulbs. If incandescents could make the grade, they'd be fine. But they can't, because they are so very inefficient.
@twirlingchair The color you talk about is very important in all kinds of lighting, whether CFL or LED. You want to look for a color temp of around 2700 Kelvin on the label. That is the warm color. LEDs can replicate about any color in the spectrum. I have seen it. It is very amazing what can be done. They are a bit pricey now but that will come down as more volume is produced and sold.
bring the price down led has been around for a while and this technology is not that expensive to produce i bet it only cost them 1.50 to make that 65 dollar bulb they charge you for.
@Painter13 you will save money in the long run, LEDs are more efficient and last longer than CFLs, LEDs don't contain mercury so you'll save your health
The statement "LEDs don't contain mercury so you will save your health" is just plain rubbish.
The fact is, fluorescent lights do contain a small amount of mercury in the form of a gas at very low pressure. Through normal operation of the light this does not escape and does not pose any threat to health whatsoever, unless you break the bulb, and how often does that occur?
Let's be realistic here.
As for dangerous chemicals? Do you have any ideas what chemicals are used in LEDs? !!!!
LEDs are an integrated circuit chip, not much in the way of components integrated but the manufacturing process is the same as the silicon chip.
Typically LEDs are made from complex semiconductors, 3-5 compounds - Gallium Arsenide, Indium Gallium Nitride, and many others and are extrinsically doped with noxious chemicals.
Not to mention extremely nasty acids such as hydroflouric acid are used in production.
@HHRich While it is true that LED's are made up of chemicals that are harmful to us - like the mercury in the CFL's, Unlike the CFL's, LED lightbulbs are extremely difficult to break - especially to the point of releasing these chemicals, so they are therefore much, much safer than CFL's. The downside is that they are still overpriced and are unable to replace incandescent lightbulbs that are over about 25-30 watts. (Some say 40 watt or 60 watt equivalent, but only in one direction.
I've been experimenting with LEDs, making my own lights, and they certainly are very different. The directional nature of the light - radiating out from the surface of the chip - is a real problem , they can't just be used as conventional light bulbs hanging from the ceiling - not without some device to redirect the light.
I notice a Philips LED bulb I have uses a silver inverted cone to achieve this. The LED mounted on the bottom, radiating light up to the inverted cone.
@HHRich Yes, it is very true that LED's are not practical for lighting large rooms or even small bedrooms. THey can be used for desk lamps and Christmas lights and that's about it. Also, if you want an LED lightbulb that pust out light in different directions, you need many LED's pointing in different directions. As for the silver cone in side of the white and blue LEDs, as I have also noticed. Incandescent lightbulbs are the safest lightbulbs to use as far as I am concerned.
@1988tq What is it with this Hg-phobia? It's one of those Internet hysteria phenomena with a grain of truth. Look. Certain compounds of mercury, like HgS (cinnabar) are toxic. (Roman women used it as a cosmetic, but it took rather a long while to figure it out.) But elemental Hg doesn't get absorbed. Modern CFL's contain about as much Hg as 1/4 of the ball of a pen. Why do people even consider this an issue?

In that case we should kill all niggers, not because they are niggers (that would be racist), but because their skin is too dark to make the grade.

I really like the burn color of incandescent so was wondering if they would have different hues of lighting for LED similar to the old bulbs.

That light you mentioned is the new generation of lights called LED or light emitting diodes. It is replacing the standard light bulb.
