|Very creative design, I can't wait to see an actual lamp.|

|Cool use of a lightguide to get the light out uniformly. I wanted more details about the construction, but your cutaway view seems broken -- instead of linking to a larger image, it just links back to the article. Could you fix that?|
Fixed. Sorry for the inconvenience.

|This is good innovation,looks to be a nice retrofit replacement,however
The price of $25 of each bulb is on higher side ,when compared with
energy saving CFL lamps,which available $ 1.0.

|Great idea ,does take an large company to spend the $ in development .
Wana bet there will be knock off designs within the month ?
Good on ya 3M

|Neat but why build an incandescent replacement that is not offered in the color of an incandescent (2700k)?
There are 5 things an incandescent replacement needs to do. Omnidirectional, 2700k, size and appearance close to a regular bulb, work in an enclosed fixture and be reasonable cost. It seems like every new bulb does 3-4 of them except maybe the lighting science omni 2700k version. It seems to get them all right. Even dispersion, 2700k, doesn't look like a bug light, works in enclosed fixtures and can be bought for $25 which is high but as good as we have today. |

My concern is about dust and bacteria accumulating inside the outer shell through the vents and due to thermosiphon of upwards hot flux of air. How can this be cleaned in a practical way?
25 years is I think somewhat exagerated and a marketing trick. Within 2-3 years consumers will be tempted to upgrade to higher lm/w versions and better CRI. So the 25$ will partially go down the drain. We all know that our laptop can last 15 years. Who waits so long to change it?
Why stick to the A-bulb shape? I am quite sure that experimenting with other shapes can improve things.

|Nice design, but 3M forgot that they are building a lightbulb, not a computer. Now look at the design again and think full automation. Well, it is impossible. In order to make LED lamps successful, somebody will have to come with design which can have under $5 cost which translates to sub $10 retail.
However, I have to give kudos to 3M engineers for ingenuity. |

|I'm also curious why it is so important to maintain the traditional bulb shape.
Vs the suggested bulb requirements of :
1 - Omnidirectional,
2 - 2700k,
3 - size and appearance close to a regular bulb,
4- work in an enclosed fixture
5 - and be reasonable cost
What drives the importance of this shape and where does it rank vs the other 4? How should the other 4 be ranked?

|Paraphrasing Monty Python - and now for something completely different
an A-19 form factor with odd design , and with flaws already stated
and a BOM of what- like 30 components. It looks like yet another
rehashing of the flaws of trying to go with DC LEDs and their, driver
capacictors et al . You would think the late arrival on to the scene
would get us a product that was more contemporary to our times.
It strikes me as a reworked 2009 model year luminiare but with a driver location switch a roo. Meh |

|Very nice design. Will it be sold in Walmart China?|

|Since it doesn't appear to be dimmable, that, and higher lumen output, would be excellent next innovative steps.|
|Name: mistero Posted: Sat, 08 Sep 2012 01:09|
|Bulbs ARE dimmable but ONLY with the following Lutron units: DVELV-300O, SELB-300P, CTELV-303P, SELVB-300P & VPEO4-ILZ. I purchased 3 bulbs at Walmart for slightly less than $25.00 but my current dimmer (incandescent & halogen only) won't work. I've ordered via Amazon a proper dimmer to install. We'll see.|

|Out of box Innovative Design.
|Name: zxl914 Posted: Mon, 24 Sep 2012 08:09|
|Very qute design, I am eager to see the true sample.
Is the heat dissipation area enough? Also bulb shape is not the best appearance for SSL.
|Name: jason teller Posted: Thu, 27 Sep 2012 05:09|
|That design is truly the best designed light bulb on the market , you can always trust 3M products to be innovative and cutting edge. I can't wait to buy this and try it out.|
|Name: ledlightingguy Posted: Fri, 28 Sep 2012 20:09|
|The cool white is actually 4000K, not 5000K as mentioned in the article. This is a very unique design compared to other A19 LED replacements on the market which are more like a snow cone design and dont have a omni-directional light pattern. These are much brighter than other 60 Watt replacements that I have tried. Until lamps are redesigned for LED Light Bulbs, this design is the best energy savings/longer life retrofit to incadescent and much better than CFL. |

|Kudos to 3M for an innovative design but I believe its time we shy away from trying to convince customers to buy a retrofit bulb that looks like an Edison bulbs. Its a new era of innovation in products and new forms should be sold as replacements that don't take the form of "HISTORY" in lighting. LED's are at the forefront and everyone knows about it and what it can do for our environment, so lets focus on Innovative Forms of LED's|
