According to analyst estimates, by 2020 the LED lighting industry will be close to a $25 billion market worldwide. LED lighting manufacturer Bridgelux wants to be on the forefront of this shift. SmartPlanet correspondent Sumi Das talks to CEO Bill Watkins about Bridgelux's new LED array that delivers 5,000 operational lumens and how its latest technology is different from its competitors.

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!
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.
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.
by going to LED lights, I'll be able to light every home in the state of florida, with just the lightning I harvest in the state of florida. :-)
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.)
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.
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.
Unfortunately, we're trading one product (w/ mercury vapor) with this "new" product, which has a heavy metal (i.e lead).
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.
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 !
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.
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.
