    Are LED Fluorescent Tubes Ready for Prime Time? 53

    Software Advice, a website that reviews software for electricians, is hosting a survey on LED vs fluorescent tubes. Specifically, they want to know if LEDs will become a standard replacement for fluorescent tubes.
    So many LED tubes...but not all are the same...

    So many LED tubes...but not all are the same...

    There has been much debate over this recently, especially among electrical contractors. Rightfully so. LEDs promise to be more energy efficient, less harmful to the earth and more economical in the longrun than traditional fluorescent tubes. Yet there are many experts who think the technology isn’t ready for “prime time.” LED tubes are more expensive up front and improvements still need to be made in the strength of the lighting.
    What do you think? Have you used LED tubes as a replacement for fluorescents? Do you think they will take the spot of fluorescents in the future? Voice your opinion by taking the survey at: Are LED Fluorescent Tubes Ready for Prime Time?

    Where $60 MILLION dollars in LED Research is going… 15

    Blue LED + Yellow + Orange = ?

    Blue LED + Yellow + Orange = ?

    So where does $60 million in LED research going? It seems a large chunk of grants from the department of Energy is going towards improving the 3 things that we’ve been talking about for a while: Price, light output and color.

    1. Price – Bringing down manufacturing costs and ultimate end costs to the consumer by improving the materials used and finding cheaper alternatives to creating LEDs.
    2. Light Output – Focusing on creating LED dies that are brighter, lenses that don’t cut light output and cover the LED “dots” that people see in bulbs and fixture, as well as creating fixtures that can be used by consumers that are bright enough to replace a 100W incandescent bulb.
    3. Improving the color output – Researching new phosphor materials (which are currently being used in fluorescent lighting as well) that make LED light “warmer”

    Looks like CREE, Philips and GE are receiving the bulk of grant money. It will be interesting to see what they can come up with as well as what the future brings for LED lighting… My question is how long until all this great research is APPLICABLE to us? 2,3,4 years? Let’s hope not…

    76% Return – LED bulbs as an investment vehicle 15

    Is there any other investment that can guarantee this kind of return?

    Is there any other investment that can guarantee this kind of return?

    Everyone KNOWS that LED bulbs save money. With the appearance of LED bulbs in more and more places ( Philips LED bulbs just popped up in Home Depot), the general public is starting to become more aware of the products that are available, but the consensus is they’re STILL too expensive.

    The truth is what few are saying is that it really doesn’t make sense financially to switch out to LEDs if you’re using them less than 8 hours a day.

    Compared to a “traditional investment”, if you are only using an LED bulb 6 hours per day, you’re making a measly 5% return on your investment – i.e. if you spend $10 for the LED bulb, you’ll “make” $0.50 per year(in savings).

    The numbers get really interesting when you starting getting to 12 hours usage per day and more. In this example, we plugged the numbers in for California ($0.15 /kWh) into our trusty LED energy evaluation calculator at 16 hours usage a day and the average return on investment is an astounding 76%! – i.e. if you spend $10 for the LED bulb, you’ll “make” $7 per year (in savings).

    Now imagine in commercial applications where you have HUNDREDS of bulbs…this savings are just immense. Is there ANY investment vehicle out there that can guarantee a return like this?

    DIY LED’s over 1000 lumens 4

    Chocked full of tips on living green

    Chocked full of tips on "living green"

    The folks over at littlegreenblog.com are doing big things. Besides providing a ton of PRACTICAL tips on living green from greening your home and how to eat right, they’re planning to delve into building their own LED lights as well!

    It’s always great to find people who share similar views on the toxicity of CFL’s and they hit the nail on the head with this post:

    http://littlegreenblog.com/green-technology/energy-saving/leds-a-new-generation-of-lighting/

    saying that CFL’s are just an interim solution to energy efficient lighting. It’s sad to hear that even in the UK, quality LED light bulbs still aren’t readily available. It’s people like Richard over at littlegreenblog.com who  take an active role in spreading the word for LED lighting that we appreciate.

    Richard comes from an Electrical Engineering background and plans to build his own LED lights using his home as a testbed and showing homeowners how they can build their own lights that put out usable quality light. From what Richard has said, he’s been experimenting with LED chips that put out 1000+ lumens!

    We’re excited to see it, and you can guarantee we’ll keep you all posted when he comes out with his writeup.

    Oh noes! Copyright infringement!! 0

    I saw this on one of those do-it-yourself websites and I was thinking that it looks uncannily like our Eternaleds company logo. Coincidence? I think not.

    Wheres the number for my lawyer?

    Wheres the number for my lawyer?

    In fact, if I were make a real life version of that, that’s exactly what I’d do. Except instead of soil, it would be powered by pure awesomeness. Actually you could call this a solar-powered lightbulb and you wouldn’t be too far off. Looks really clean to boot. If I ever get a thumb green enough, I’ll try this and post it up.

    At least I know what I can do with the bulbs I’m not using anymore

    Art Lighting – How to NOT do it. 11

    Looks like a fiery upside-down tulip

    Looks like a fiery upside-down tulip

    So personally I love lights. And I love cool applications for lights such as the Iron Man costume, but for me part of the charm and wonderment stems from an almost magical sense that the light is coming from nowhere. This artsy ceiling light by Designer Christopher Moulder accomplishes this by making the entire shade part conductive. Pretty neat idea. It uses little 10W xenon bulbs, which combined, total almost 300 watts. Could probably be more efficient if LEDs were used but maybe the xenons are extremely bright. Either way, I’d love to see some more designs that use LEDs since they would not only look good, but taste good be good for the environment as well. I have a few projects in mind in the next few months utilizing the portable nature of LEDs, so we’ll see what I can come up with. Stay tuned.

    ANYONE can sell LEDs! 13

    Chinese manufacturer logo - are you kidding me??

    Chinese manufacturer logo - surfing babies what?! - are you kidding me??

    I just got an email in our inbox today. We get spammed about 5x a day from different manufacturers in China trying to get us to sell THEIR LED products. This one was particularly funny since it DID get my attention, but not in a good way, with their attached logo of a chinese baby “catching a wave”. (I can’t make this stuff up people)

    The emails generally consist of a Dear sir/madam – followed by extremely broken English, with an attached pricelist asking us to consider them to be our manufacturer.

    Here’s an excerpt:

    “Dear Sir,
    This is Vickey  who come from Shenzhen *** ,LTD .I am kindly know you are in the market of LED lights.I would like to     indroduce our comapny and products to you ,Hope to we could build business relatioship in 2009.”

    I left the spelling errors in there on purpose. Do they REALLY expect us to buy their products, if the first sentence in their email is plagued with grammatical and spelling errors?

    There are literally hundreds of new manufacturers in China trying to jump on the LED bandwagon, and make LED light bulbs. The question is what % of them are complete garbage?. We’ve taken the time to contact a number of manufacturers and tested their products thoroughly, before deciding on who to go with which is why we can offer a 2 year warranty and 30 day guarantee.

    Once again, buyer beware – there’s a ton of new websites cropping up selling LED lights, at LOW prices. Their manufacturer can very well be the one who can’t even hire someone who speaks english, or uses surfing chinese babies in their logo…would you spend $40-$100 with them?

    Anyone else seen some questionable websites? We’ll be happy to scope them out and give you the lowdown.
