RE: Lighting the world with LEDs
i honestly want this company to hook up with every major box store, if each store saves energy and sees a return even 5 years down the line and replacing expired units will be cheaper in 5 years as well, we might not see a strong inflation of in goods. Beacause as we all know, their cost because our costs. And lets face it, box stores really control many of the competing prices, and our wallets.

RE: Lighting the world with LEDs
They need to incorporate a way of using them in a regular table
top lamp . These new LEDs look promising and should be made
available for the homeowner to use just because businesses
aren`t the only ones feeling the pinch. The sooner the better. A
question i`ve been thinking about is using a magnifying coating
on the cover to help increase the light being emitted ( is this
possible?). Send me a check for the idea , Ha Ha .

Have a Great Day !

RE: Lighting the world with LEDs
Sorry, but the high initial cost makes these an unreasonable consumer purchase and the unreliability of LED consumer bulbs (I have had 4 stop working with less than a year) have had a negative impact on my willingness to purchase them. I will use my reliable existing source of "analog" old filament technology and then use my stock of compact fluorescents till the consumer LED market matures. The perhaps I can buy an economical dimmable unit which gives adequate light and uses low wattage and is subsidized by the power company since it reduces the need to further invest in power generation.

RE: Lighting the world with LEDs
Unfortunately, we're trading one product (w/ mercury vapor) with
this "new" product, which has a heavy metal (i.e lead).

Lighting the world with LEDs
Every light bulb has connections with lead, from the first mass production of incandescent bulbs, and it's been the choice for a century now. Do yourself a favor and study the whole lighting industry.

RE: Lighting the world with LEDs
Sumi, please ask for more details, like what is the cost for this array
and for it's competition? How many lumens does it give? Etc.

RE: Lighting the world with LEDs
This is an exciting development. I presume this new light source also produces less residual heat. I that correct?

I've converted nearly all of our incandescent and compact florescent bulbs to LED bulbs and have been very pleased with the light they emit. The initial cost per bulb is high, but the operating costs are much lower. Unfortunately, the local power company, PSE, is still pushing compact florescents, despite the fact they contain mercury, so there has been no program of replacement in the Seattle area. It is strictly voluntary.

RE: Lighting the world with LEDs
that is so cool. we need to start rating lights in lumens and forget the watts thing, because those LED's probably produce the output of a 100W bulb at less than 1 watt. One led is about 10 thousanths of a watt. (10 miliwatts.)

RE: Lighting the world with LEDs
I bought an LED light for a fixture that is on 24/7. It only lasted 3 months..so I think I will wait for a more mature product before I invest again. My incandescent bulbs last much longer.

RE: Lighting the world with LEDs
If you are buying LED's for home use make sure they are energy
star rated.

RE: Lighting the world with LEDs
pagegardener - maybe not the LED technology that is not mature but perhaps the company that assembled the bulbs you got? The LED's can be fussy about proper voltage, being kept cool with a heat sink, etc... things that should be designed into the bulbs. I have a 5 watt, 3 volt flashlight LED bulb connected to a low voltage transformer - it's used to light up a small storage room in my basement. It has been on for over three years and hoping will last at least another 10.

Relighting the world with LEDs
My only real problem with LED lamps is the cost, then some are low on QC in production. I'd have converted exclusively to LED bulbs for every application, except for the cost and the need to use up the older bulbs that I still have in stock. I've been "playing with electricity" for 50+ years, and the semiconductor industry is making a very big advancement in one of the most important parts of our lives, simply seeing what we look at during the night! Other wavelengths are giving Doctors and researchers vast new ways to improve our lives, with no end in the future.
I'll be the first to change my car headlamps to LEDs, when the same light output is available. Sure beats dead car batteries and "the death flash at night" when an old bulb goes dead, while a problem is in need of being addressed!

Music Sumi Das: According to some analysts' estimates, by 2020, the LED lighting industry well be a 25-billion dollar market. Bridglux wants to be on the forefront of this shift. Recently, it announced a new LED array that offers better performance. Here to talk about what the company is doing in this area is Bill Watkins, CEO of Bridgelux. Bill thanks for joining us today. Bill Watkins: Thanks for having me. Sumi Das: You brought the new LED array. Tell us what makes this revolutionary. How does it differ from this current existing LED array? Bill Watkins: Well, this is our newest generation of array, which is really a solid-state light source. It's a 5,000 lumen, high output light, really designed for those areas in retail stores where they need a high quality light, and they need a lot of energy savings. It is in competition and replaces this, which is another LED light source. Sumi Das: Clearly, it's larger, but these both produce the same amount of light? Bill Watkins: Same amount of light, only this particular product uses single emitters -- Sumi Das: Okay. Bill Watkins: -- Of red, green, and blue. And if your eye sees red, green, and blue, it sees white. Sumi Das: Okay. Bill Watkins: What we do is we have just one color, and we shift everything to white light with our phosphorous coatings. This allows not only to get, obviously, a smaller point of source, it also allows a higher quality light and at a much lower cost. Sumi Das: So you've simplified the manufacturing process because you have -- Bill Watkins: We've eliminated many steps. Sumi Das: -- Fewer pieces. Bill Watkins: Yep. Sumi Das: Okay, so this is used in a light, like the one you have there next to you. Bill Watkins: Right. So think of this as a light bulb, and we would put it into a light source like this, and this would be hanged from a ceiling that happens to be a commercial application. Sumi Das: Right. Clearly, that's not a residential application. Bill Watkins: So -- no. Sumi Das: I'm not going to put that in my home. Bill Watkins: No, but again, the commercial business, because of the fact that they use a lot of energy; it becomes a very easy conversion to convert to our source. Sumi Das: There have been a lot of criticisms of LED lights. Some people are saying that, you know, the quality of the light is harsh. It's not a warm light, like incandescent lights -- light bulbs offer. And the other thing is that it's expensive. That's the main gripe that people have. So does this new LED array respond to those criticisms? Bill Watkins: It's all part of a path in the evolution. I think this technology is very exciting. You know, at Bridgelux, we're very passionate about it, but this product is -- it allows you to have a light, and actually, if you put this in your light source, you will find that you don't know that you have a LED in it. Sumi Das: Really? Bill Watkins: It will look very much like an incandescent. And again, this is where we're trying to do. Sumi Das: That's a serious challenge. Bill Watkins: It is. Sumi Das: That's a -- Bill Watkins: But you'll see that improvement. I mean, I think any technology at a stage -- and I think the criticisms of LED are really for three or four years ago. And the progress that people have made over the last two or three years have been phenomenal. And as you see, the concept, just from us able to do this versus this, phenomenal not only on the quality of light, on the cost of that light. Sumi Das: But the expense. Bill Watkins: The expense will come down. It's just scale. Sumi Das: Okay. Bill Watkins: In scale and volume. And you will see -- Sumi Das: So it will take a while. Right now, it's not significantly cheaper. Bill Watkins: But every year, if you look at it, the costs are dropping by half. And with the energy savings, it is. Sumi Das: But you know people are impatient. Consumers want it cheaper now. Bill Watkins: But the commercial people are driving it. Because commercial, in this particular application, they see a two-year payback. Sumi Das: Okay. Tell us about the future of LED lighting. Because these LED arrays have chips in them, that enables and opens up a whole host of applications that we never had with incandescent bulbs. Bill Watkins: Well, and that's a great opportunity. What really makes it exciting is it's not just replacing an incandescent bulb. We're putting into the -- a digital solution into your home. I mean, an incandescent is sort of the last analog part we have in our house, and so the opportunities are unlimited once you start having, if you will, what I call very smart chips in your light source. Sumi Das: Bill Watkins, thank you so much for joining us today. We appreciate you showing us this new technology. Bill Watkins: All right, thank you for the opportunity. Sumi Das: For SmartPlanet, I'm Sumi Das. Thanks for watching.
