LED bulbs for household lighting

    Every box or package I have looked at says otherwise. The difference is small, from here on out it will be incremental and not the huge jump seen going from incandescent.

    I ran into this when doing landscape lighting, the entire industry is trying to settle on one standard and the preference of choice is lumen. This works better than lux for an all-around gauge because you can still get an idea of light output no matter what the end use is. Lux is well suited for a lighting designer who needs to figure out the correct lighting for a specific environment and task but totally useless for any long range lighting so it doesn't work effectively as lumens for all-around measurement.

    The Edison socket is merely the means of power delivery and doesn't dictate the technology used with it anymore. Regular fluorescent fixtures aren't as efficient as LED or CFL, yes there are high-end fixtures that are but they are very expensive and only seen in large commercial installations.

    The light quality from LED is definitely superior! Even the best fluorescent tubes are still obnoxious, the light quality just doesn't quite reach an acceptable level. I know some people are more perceptive of this than others and I am one of those, I can't stand fluorescent light and the cheaper tubes even give me a headache.

    Sorry, I was not suggesting CFL was better for outdoor use, in fact it was a still-born idea as far as landscape lighting is concerned, the aforementioned cold issues being only a small part of what killed it.

    I bought LED bulbs for the kitchen

    we were using halogen and replacing them every 3/4 weeks

    I bought 3 Bright white LED bulbs and they are amazing

    instant white light

    they have been in there now for around 18 months and none have blown

    there was also a lifetime guarantee with them

    they were around

    I replaced the lights in my RV with LED's and they hardly draw any current.
    I also have an old 10' trailer at our hunting lease, that I built a bank of 24 LEDs for. The lease has no power, so I run this one off of a golf cart battery.
    The battery don't go dead because I tossed a solar charging strip on the top of the trailer.
    BTW: 24 white LEDs are very bright. The trailer lights up like bright sunlight. Great for reading.
    Now I'm rigging a Smartphone charging stations in the boondocks...

    I read a news article about LED lights just a few weeks ago, and apparently there are two types (in the way they are structured).
    One is more expensive but lasts longer. Brands like Panasonic and other Japanese brands are using this method.
    The other type is cheaper but it does not last as long.
    The thing is, I cant find the article or remember the details....

    Apart from that, LED has a smaller area for the light to travel.
    You will have to choose a well structured bulb that has good reflectors in it in order to have the light bulb light the same area as a normal bulb.
    Some LED bulbs simply add more lights to make it brighter and shine wider, but that can result in added weight, putting too mush stress on the socket.

    Since getting the right bulb can save you electricity and fewer changes in the future, you muight want to indulge in good expensive bulbs for now until the technology becomes more stable :)

    just make sure you take them strong enough, because they already make 1 watt bulbs to but you can compare these to a 10 watt "normal" light, just rubbish! look out for at least 4 to 8 watt bulbs!

    we use CFLs throughout my house. they are WAY cooler than incandescent light bulbs. a three pack is normally on sale at menards for like 89cents or something like that. above my computers i have xenon bulbs but the problem with them is that there HOT! kinda scares me so there off unless were actively using them. and unless you buy the really expensive CFLs that are specifically designed to dim, you will blow your dimmer switch up. lol

    The different LED's you refer to are these.

    Original LED


    Luxeon Emitter


    The original LED can produce a large amount of light with sufficient bulb count but what can be done with 9 1 watt Luxeon emitters will take 80 super bright LEDs.

    The weight of another Luxeon emitter is in grams so it is not substantial enough to make a difference, the added weight comes from the driver and heat sink. Also now that LED's are reaching this level of light they are no longer a cool light source, the emitter is producing heat now and the driver can generate considerable heat.

    1 watt emitters are more than sufficient for the job, plus the larger emitters go up in heat production. With the 1 watts you simply add emitters to reach the desired output and light pattern with the proper reflector.

    The 3 watt and larger are generally reserved for large flood, spot or flashlight duty.

    Ever had one of those cheap Chinese CCFLs blow-up on you? See post #21 in this thread. They stink.

    Actually there are many kinds of LED chemistry, physical layout etc., and many more uses for them. From the original red GaAsP LED that I used to buy in quantities of 1 back in the early '70s to the latest "white" LED-based products that can work on household AC, there's a wide range out there.

    Recently there has been a lot of news about the use of LEDs in the home. This is mainly as a light source for backlit LCD displays and "screw in" replacements for incandescent bulbs.

    When it comes to making "white" light, there are a variety of different methods, each with their benefits and liabilities. There are a lot of companies, large and small, working hard to improve the technology. One thing that has been more or less common in simple white LED lamps is the use of colored phosphors that are excited by the primary emission of the LED material, making a light that appears to be more or less white to the human eye.

    Initial cost, product lifetime and other retail considerations matter, of course. But so do other things like how close to "natural" light (the definitions on that can vary widely) the devices are. The ideal white light has a ruler flat frequency response across the visible spectrum, and wastes as little energy as possible to unseen frequencies and heat. We're a long way from that ideal.

    I don't pay for electricity anymore since going solar in 2009, so I'm mostly interested in long lasting bulbs, not energy efficient ones. Just curious on what folks recommend for that. I have an outside light shining on my flag every night and that flood bulb goes out every six months because of usage.

    Is that one of those halogen flood lamps? I found bulbs never lasted very long either. There are LED flood lamps...

    Wow, 100% solar, that's pretty impressive and awesome!

    I believe Sharon does live in SoCal. Something like it never rains in Southern California. :) Don't think you could do 100% solar electricity in the United Kingdom. LOL

    I've got solar water heating, It's nowhere near 100% though, probably more like 30%-40%.

    For longevity LED is the best choice and there are many options available. How tall is the pole and how big is the flag?

    I live in the Bay Area, which is considered Northern California :)

    I had solar panels installed when I had the roof redone. It was a real no-brainer, my house is almost all glass ( why I don't throw stones ha ha ) and I was paying $$$$$$ for electricity when using the air conditioner.

    Right now I have the Giants' flag a flyin but normally it's Old Glory:

    Sharondippity: waiting for tonight's game....

    That flag is 5x8 but I don't know the exact pole height.

    I would suggest a 9 emitter up light like the FX Luminaire NP9 but you will need a transformer. PM me and I can give you other options as well or tell you where to find it.

    Short answer: go LED if you can. They're getting much cheaper - I bought a GU10 recently for

    I have 4 LED's in my kitchen. I say 4, each unit contains 3 LEDs @ 4 Watts each. So Each unit is 12 Watts, but each unit has a brightness equivalent of around 75 Watts of normal Halogen bulbs.

    The ones I have are

    Here's a strange thought: if the LEDs in my bathroom last as long as they claim, I'd probably be replacing the bathroom before I replaced the bulbs.

    Strange world where your bulbs lasts longer than your bath ..

    lol, I redid my bathroom at the same time I put the LED's in (photo above) so I'll see which lasts longer.:D

    Welcome to the future!

    I'm already getting that with CFL bulbs. I'm stuck with a bunch of 'em! My last apartment had regular bulbs, so I bought enough CFL bulbs for it. And I put some in my mom's house. My new apartment already has CFL lighting, and when my mom's house was sold, I took back my CFLs. So I have a box of them in various sizes and no place to put 'em!

    You call 5000K (a.k.a. "cool white") warm? :confused:
