Edison-Inspired LED Lamp is Energy-Efficient Replacement for Incandescents

Edison-Inspired-LED-Lamp

Lighting Science Group Corporation® has launched a new line of LED lamps that can serve as direct replacements for traditional general purpose lighting. The Definity Professional A19 LED lamps have been created with lightweight aluminum CoolPoly® thermal material that results in a lighter, more efficient, and less expensive option than incandescents.

The Definity Professional A19 LED lamp can achieve performance values of up to 71 lumens per watt while capable of dimming down to 5%. The GP19 LED lamp, which is also dimmable to 5%, compares to 40 watt lamps in ENERGY STAR equivalency performance at 80 lumens per watt.

“Consumers have been asking the LED industry for bulbs which more closely replicate the form and function of a traditional Edison bulb,” said Lighting Science Group Chief Executive Officer, Jeremy Cage, in a recent press release. “These new lamps represent that, and much more—they are highly efficient, emit a beautiful light, contain no mercury and are a strong LED value. These lamps make every room more beautiful with their lighting quality.”

The Definity line is the latest innovation from Lighting Science Group, which was recently contracted by The Bionetics Corporation to help develop LED lighting solutions for the International Space Station (ISS). NASA’s primary contractor for the ISS, The Boeing Company, will be working with Lighting Science and Bionetics to develop lighting systems that will help flight crews maintain circadian alignment while aboard the ISS.

    So I will be able to go into a store and walk out with a 8 pack for $3. I doubt this will be the case. I bet you will still be buying each for $15. Just stop this and give me my choice of light bulbs back. If I wanna spend $3 on incandescents and the cost of operating them, why limit my choice?

      Where did you get the idea that you can’t buy incandescents? You can, they just have to meet a higher efficiency standard.

      As for LEDs, they’re not $15. The prices have been coming down rapidly. Now, I can buy regular A19 LED bulbs for $5 at Home Depot or Lowes, as my State promotes LED purchases. When older LED models go on clearance, I can get $20+ bulbs for $2. This happens alot, since LED bulbs are like computers, in fact, LED bulbs are basically computer chips. Like computers, the chips get better and better, and thus new bulbs come out, and the older models go on clearance. Voila, $2.

      As for the light quality, warm LEDs at 2700 kelvin are exactly like incandescents. You really need to stop in a store, because it seems your info is old.

        I’d like to see Congress pass a law and have President Obama sign it that would force bulb manufacturers to sell all LED bulbs (regardless of lumen output) at or below 5$ a bulb. If Congress can mandate “efficiency standards” for bulbs, then it can mandate the price of bulbs too. And yes, every bulb in my home is an LED bulb. By the way, you’re not giving an accurate description about LED bulbs. Want an LED bulb that can be used in a fully enclosed lamp? Then Switch Lighting bulbs are your ONLY choice. Unlike incandescent bulbs, the Royal Dutch Philips bug-lights can’t be used in a sealed lamp, it voids the short warranty and kills the bulb prematurely. Want a dimmable LED bulb? Better shell out more and make sure it works with a compatible dimmer.

          “accurate description”?!? I didn’t have time to write an essay, just the minimum, and ultimately, the original poster needs to go to a store and update her knowledge about bulbs since she seems rather confused.

          I, too have switched over 90% of my bulbs to LEDs, with just a handful of GU9s and MR16s that I’m waiting to find on “clearance”. As for enclosed lights, I have alot of vaportite buckets with LEDs, but they are made for recessed light housing. And, dimmable LEDs, I think the dimmers are a bit hit or miss. I’ve had luck with $10 Lutrons, but I think alot of people don’t realize that you need to have a minimum load on the circuit, and that one LED, will probably be too low for older dimmer switches.

            Sorry buddy I am not a female. For one I am in a Lowes almost every other day. So to say my info is old sorry it is not a few hours from my post but a day or two. Again read and try to understand about choice. Choice does not have a disclaimer that is suppose to say yes you can have all you want but has to be this efficient. That is not a choice. If I want LED or CFLs, I would buy them but I don’t want them. Yes I can buy incandescents right now but not for long. If they were not being pushed because certain companies can make more money per bulb then you would not see them right now.

            You made my point and you don’t even see your own hypocrisy. You can only buy them on clearance for the cost of an incandescent. People like you are the reason others have no choice. Maybe you should wake up and open your eyes to your hypocrisy.

            If our government tell us what bulbs we can use, why not mandate that they are free or 1 penny?

    amoyer – you have lots of choices, they all just happen to be more efficient and save you money in the (not so) long run.

    If you want cheap, then go CFL (I’ve gotten 5 packs for $3). If you want more efficient and no mercury, go LED. Halogen is still an option, and GE has been promising more efficient incandescents that will meet the latest (still not all that tough) efficiency standards. All sorts of choices.

    No thats not a choice. I have to choose between a health hazard or paying an arm and a leg for my light bulbs. That makes no sense to a reasonable person. I guess we should outlaw all automatic transmissions because they are not as fun to drive by that logic. A choice is not limiting the amount of an item to a small description based on a certain mentality of thinking but instead of having every option available to you no matter what. That is what choice is.

    That’s hysterical that you think there are lots of choices out there. CFL’s are a health issue (not only when you break them,) LED are just way to expensive and Halogen is beyond LEDs. Be in a room with LEDs or CFLs, then compare to an incandescent lit room. You will feel more comfortable and headache free in the incandescent room, you can not say that for the CFL or LED lit room.
