Rechargable Lightbulbs

    I watch Weather Nation and they have been having a commercial on rechargeable light-bulbs. Rechargeable light bulbs are expensive but interesting. This is a blurb from a write up on a different rechargeable light bulb.

    Self-Charging Light Bulbs : Rechargeable Light Bulbs

    I read a few articles and most say these rechargeable bulbs last for approximately 4 hours on a charge. Many of these bulbs now come with a portable socket so you can take it from the lamp and use it like a flashlight. The articles say it will work like a normal bulb when the power is out, just turn on the lamp and you will have light. Has anyone tried these bulbs? I rarely lose power but it would be a great gift for my folks back home who lose power quite often.

    YJY Rechargeable Emergency LED Light Bulb A19 Lamp, Still Work after Power Outage, 75W Equivalent 12W 6000K E27 E26 110V 120V 220V - 1 Pack - - Amazon.com
    • **Rechargeable and Emergency** - Very special and intelligent LED bulb, there is a lithium battery included, the battery will be charged when you use the bulb daily, so when real power outage, battery will release energy for emergency lighting.
    • **Intelligent and Convenient** - Electrostatic induction switch, the emergency system will start automatically several seconds later when real power outage, and you can turn off the bulb by your socket switch just like a normal household bulb, useful for outdoor camping and some industry area.

    They are definitely interesting. I heard about them from an acquaintance. The only issues I can foresee being possible are buying expensive light bulbs which may go bad in a year or two due to any number of complications we don't know about since these are very new, and the other would be safety...namely fire. Granted, I could be a little too skeptical as to their efficacy now, and this may change as time goes on, but as of right now I wouldn't take the chance, personally. Light bulbs are a simple device, and when we make them more complex we could risk creating more problems.

    All that said, if these do work, I can see the attraction...unless one has vaulted ceilings or kids who are too curious and won't leave them alone.

    Yep. There were some calculations run back in the 40s that say in effect that doubling the possible modes of failure quadruples the odds that failure will occur.

    These are an intriguing idea. not a fan of early adoption on tech. As an example, The '20 year' LED bulbs have a significant failure rate at 8-12 months if they make it past 2 years they seem to be ok. But not worth the extra cost for me. And I haven't found a light spectrum in LED that agrees with my eyes. Especially not at night

    Agreed @Ganado. Give me the good 'ol fashioned light bulbs that we have used since forever.
    I bought up all I could find when the news first broke that they would no longer be made.

    Failure was one thing that caused these rechargeable light bulbs not to have such great ratings. One person bought 4 and only two worked. There was also comments on flickering and one reviewer stated that the light bulb went on when the lamp was supposedly off. I am sure some of this is due to electrical issues outside of the bulb. I think it is an awesome idea and hope that it gets perfected. I would buy some, still may but the fire danger bothers me.

    Good enough. I like older technology that has a track record, not every energy saving gadget passes my test. The power company bestowed a slew of kwh saving bulbs on me a couple years ago. Trouble is, they don't fit all my fixtures and lamps. Oh, well, some do, and I have plenty. And some flashlights for outages, which do happen up here on the hill.

    When they had the big bad light bulb ban I laughed.
    Even back in 2008 7 out of 10 people had already switched or were starting to use energy efficiency lighting which at the time was CFL. Then 2 out of 10 were considering switching and the remaining 1 in 10 didn't know their ass from a hole in the ground.
    I guess the Democrats just don't feel a live unless they take the perceived moral high ground and ban something they don't agree with.
    We had 2 wars going on and national debt out of control and they saw fit to ban light bulbs. And they wonder why they are out of a job.

    You can still get incandescent bulbs. They are rough service. They cost a little more but work and light exactly like old incandescents. They cost a little more but last 2 or 3 times longer than the standard cheap incandescent bulbs.

    The fact of the matter is that light bulbs do not emit light. They absorb dark. If you notice that when a light bulb no longer works, it tends to turn black. That's an indication that it has absorbed all the dark that it can and is filled to capacity.

    It's a nice idea .
    the technology it takes to know the difference between a black out and the switch merely shut off is remarkable.
    Almost sounds like a con game to me.
    Not that it even effects me seeing I'm on battery solar,wind and grid. Most all my light are DC .

    Hmmm... I changed the entire house over to LED lights over a year ago and so far so good. Costly but glad I did it. I am a little concerned that this has a lithium battery that could melt/leak/overheat/explode but... Now, I also have smoke detectors which have alkaline batteries but they are not being recharged so... When it comes to anything about fire I am a bit freaky for if a fire ever got started where I live - well - it is adios Bandito.

    Interesting concept, but kind of pricey for what is basically a glorified flashlight.
