LED Bulb with Filament Bulb Appearance

What can you do if you’d like to use an energy efficient light bulb, but you think that they look funky? How about a LED bulb that looks and functions almost exactly like an incandescent filament bulb?

Panasonic has introduced a clear bulb with a standard base that looks almost identical to an incandescent. It has a warm 2700K light color, similar to an incandescent. It has the lifespan (40,000+ hours) you would expect from an LED. And it only uses 4.4 watts of power, but produces 210 lumens, the light equivalent to a 20-watt incandescent.

This bulb also has a color rendering index (CRI) of 80, which is similar to other LEDs and good CFL bulbs. And, as with other LED bulbs, the bulb contains no mercury.

The release date and anticipated pricing aren’t available yet, but similar bulbs have been in the $20 to $50 range when first introduced, and prices have gone down as production makes them more available.

The Panasonic bulb is only a 20-watt equivalent, but it would seem reasonable to expect that a 60-watt version will be along in a couple of years. This bulb is also not dimmable. But for most purposes, this should remove one of the last objections to non-incandescent light bulbs.

    Well, I have two objections to this bulb. 

    The first is that this is accepting the frame that the incandescent bulb is the ne plus ultra of lighting technology, and all other lights should just try to imitate it. As we saw with the Plumen bulbs other technologies can do things that incandescents could never dream of. What is the awesomest lighting LED can deliver?

    The second, and the most important to me, is that we know the greatest part of behaviour change is influenced by what other people are doing. Nobody ever does a cost/benefit matrix on the many factors involved in buying and wearing Ugg boots–they just see other people wearing Ugg boots and then buy some for themselves. This Social Proof is in fact how the vast majority of our decisions are made.

    So when we buy a ceramic coffee cup that looks like a paper cup, or a LED lamp that looks like an incandescent, we continue the message that “I am a butthead that will not change, no matter what the environmental consequneces may be.” We will have greater effect spreading change if other people can tell we have actually made change.

      Incandescent light most closely mimics the light of the sun, it looks the most natural.

      So you’re opposed to everything that mimics something else…no matter how beautiful the design…doesn’t that make you the “butthead?” Climb off your soapbox.

  • BrianJewett

    I agree whole heartedly with Ruben and would like to point out that we go out of our way to be sure our light source is NOT visible when in use anyway. So what exactly is the point in creating a lamp that so carefully imitates the appearance of something we don’t want to see working in the first place? This is just an echo of the republicans BS attack on CFL’s that used lies and misinformation to try to rally the ignorant to their totally unrelated causes.

    • John Barksdale

      Brian, why are you getting excited about 210 lumens of light output? Isn’t that the lumen equivalent of a candle? Why can’t central-planners like yourself allow the incandescent to compete against these LED bulbs in the free market? If you don’t like incandescent bulbs, don’t buy them.

      • BrianJewett

        Must be my comment about luddite republicans that set you to barking because I never even mentioned incandescent bulbs. I was discussing irrelevant design features.

        • Dennis Jones

          Your real fear is Tea Party and global warming deniers……but hey Jack, I just want to see without spending a lot of money….quite frankly, the environment is not my concern. I live in the country and have thousands of trees to cut down and burn. Nature is beautiful out here. Leave the city for a week and come on out.

    • Timothy Stevens

      It really depends on the style of design; a lot of modern industrial fixtures actually have exposed bulbs.  If that’s the design aesthetic someone is going for, these lights would certainly fit the vintage industrial designs better than a CFL or other LED. 

      Personally, I’m against the light bulb ban; it’s an overstep of government authority.  A much better approach would be an efficiency tax (previously discussed in the Jetson Green comments).  If the government has a right to tell its citizens what bulbs they can buy, that authority extends beyond just light bulbs, and the next product decision they make could, potentially, not in the best interest of the environment. 

      Every light bulb we have in our house are CFLs, and in the garage we have fluorescent fixtures.  We have also made the decision that we are going to transition to LEDs as the CFLs die.  So it’s certainly not that I support incandescent bulbs, but I would like our freedom preserved.  I also do not agree with the fact that I’m not allowed to have a few egg-laying hens at my house (no “farm animals” allowed in city limits).  Land of the free indeed…

        The government did not ban incandescent bulbs. The government established an efficiency standard. There is a big difference. This helps drive innovation.

        • Timothy Stevens

          It is, in effect, a ban; an analogy would be increasing safety standards of passenger cars that requires a certain length, height, and weight.  It wouldn’t be banning small and mid-sized cars, simply increasing safety.

          agree with Tim Stevens – and it is also in effect a ban on all incandescents before 2020
          including the new halogens, from the EISA specifications See

        Agree…  all light bulbs have their advantages, it is a pity that CFL scare tactics is the main defence used to keep incandescents  
        The savings from banning incandescents are not that great anyway from DOE data etc, see other comment

    • Dennis Jones

      ell…. you might have made an impression up to the point where you became political. I do believe it was a republican who struck a deal with the Chinese in the first place. However great LED’s are, they have along way to go and will surpass Incandescent. But the American manufactures need to show creativity. I’m building a home and am waiting for new RGB/DMX ideas. Do you know of any?

  • Terry

    I recently found that you have to look for a dimmable bulb in an LED. Not something that society is used to with the incandescent.

    I refuse to transition to CFLs for a number of reasons, but it is still difficult to find a LED that has an adequate amount of light. I recently changed 2 GU10 bulbs to LEDs and they give adequate light. They don’t dim though as I found later. They do sell them in some of the big box stores.Terry

    • Dennis Jones

      I’ll transition from incandescent to LED….. I don’t like the CFLs. I have some and am not all fuzzy and cozy like I was promised.

    I don’t think I’m holding this up as the ne plus ultra, but there certainly are instances where fixtures do have exposed bulbs, and I can conceive of instances where, as a designer, I would choose to use something like this.  But there are other instances where the appearance of the bulb is not a factor, and different choices can be made.

    I agree that there should be other things done with LEDs that take full advantage of the technology and do things that other lights can’t do.  But I also think it is beneficial to make new technology accessible by making it available in a familiar form factor.  Neither is going to be the final word in LEDs; what is most compelling about this is the additional options it opens up.

    Hmm…. talk about Re-inventing the Wheel, at great expense!!!

    There’s a lot of talk generally about “new great LEDs”
    OK, so why ban the simple incandescents then ??

    If the new LEDs are so good,
    presumably people would voluntarily buy them
    Price is only one factor, people buy other “expensive to buy but cheap in the long run” products, imaginatively promoted, eg Energizer Bunny battery commercials etc
    - instead of like light bulb manufacturers go look for a ban on cheap unprofitable bulbs,
    as referenced http://ceolas.net/#li12ax
    the site also covering why the overall savings are small
    (1-2% of grid electricity using DOE etc data, compared to more relevant generation, distribution and consumption measures)

    Nice looking bulb. Way too expensive though for the wattage or lumens. I can buy LED bulbs for a little over $1 a watt now at HD. There’s a 9 watt LED for $10 that has an incandescent shape that is frosted. The only aesthetic difference is this Panasonic bulb is clear and doesn’t have an obvious heatsink. This bulb needs to get down to $5, and I might consider it for some nightstand lamps.

    Looking for a vendor in California - any ideas?

    Now a days people go for panasonic fillament bulb because of it’s simplicity and great output. It doesn’t get fed like normal bulbs.
