Comments on: New Luminescent Bulbs May Outshine LEDs and Fluorescents

These are a great idea, not because of power saving, but because they produce a better quality light than the other two “power saving” options. Personally, I would prefer not to have to buy products with mercury in them, nor expensive LED’s no matter how long they last, since both have poor lighting quality, and cannot be used to heat a room if needed, as can incandescent bulbs, in colder climates. The best solution, here in Arizona, would be to get the cost of solar panels down to where it would be cost efficient to have a solar system lighting your home (typically 5% or less of your usage) and not rely on the grid at all for this. True, you’ll probably have to spend quit a bit still for the REAL power hogs, air conditioning and cooling, refrigerators, TV’s, etc. I don’t get how saving 2% of your power bill a month by switching to other lighting, which costs, typically, years to pay back, will help anything, BUT if they outlaw the BEST lighting source ever…incandescent, I’ll have to go with quality of lighting, rather than energy saving factors, and therefore the ESL is a good choice.

everybodies:
I have seen the comments about LEDlight, they all think is its high price but its energy-saving,environment-protecting and any other advangages,ok ,with the development of LEDlight ,its price will be down ,i think LED light of RWJ Lighting Technology Co., Ltd is very good ,you can have a look.if you want ,i will let them give you the lower price ,see the website:http://www.rwj-lighting.com/

In reply to Jeff. Jeff, you contacted me and sugested that I buy some LEDs from a company in China. Why should I buy cheap junk from China when I know that the quality is poor? The industry in China needs first of all to be honest and secondly it needs to get on the ball with quality control. No one wants junk.

Nice LED bulb, but there’s more LED light bulb at, http://www.kledlight.com, maybe you would be interested .

This sounds like a great idea but one concern has me thinking. The old standard for television sets was the cathode ray tube, which emitted electromagnetic radiation, which was dangerous at close range. What are the effects of this technology in light bulbs at close range?

MetaEfficient has always the most interesting stories on the web. I heard of this bulb before eons ago. It might have actually been on this website. I can’t remember. If this bulb works like a cathode ray tube, does it also produce x rays like a crt and does the glass need to be leaded?

The power factor is not important for power generation, but does affect distribution. A simple way of putting it is that fluorescents (also motors and other devices), create a sort of “back current” (not really, but sort of), that requires extra line capacity.

So power companies charge for low power factors because they consume transmission capacity. You can neutralize this with capacitors, but that makes you consume a bit more, plus has an installation cost.

To the moderator,

Please correct one line in my prior comment to say: “The ESL bulb beats out the CFL and LED. ESL bulbs have a power factor rating of 0.95-0.99. CFL and LED lamps have a respective power factor 0.5 and 0.8”

And provide the following link for the source of that quote:

Thank you, bpowers

I’ve done my best to research this bulb and I’ve never seen an article that says that they produce more lumens per watt; instead the newer articles talk about energy efficiency in terms of power factors and state that “he ESL bulb beats out the CFL and LED. ESL bulbs have a power factor rating of 0.95-0.99. CFL and LED lamps have a respective power factor 0.5 and 0.8”… I don’t really understand why power factor ratings are so important but apparent utility companies consider them to be important and charge industrial or commercial customers more when there is a low power factor.
