Sanity -> RE: incadescentr lightbulb- to be phazed out (12/18/2007 7:48:42 PM)

They're very bright, I would say brighter than 40 watt bulbs, using a tiny fraction of the energy. They come in banks (where the tubes would be in a standard fixture) with many LEDs in each bank and they're faced away from the area to be illuminated, then reflected from a polished mirror surface in the fixture itself. They burn forever, too.

Edited over some slight confusion in bulb brightness, the newest flourescent tubes (I forget what they're called) are extremely bright, and the LEDs I installed aren't quite that bright but they are brighter than the old 40 watt T8 flourescent fixtures with two or four bulbs in them. What are the newest ones called? Just when we got converted over from T12 to T8 it's time to start upgrading yet again!!!

Any UV radiation given off by these LEDs? Any stroboscopic effects?

I know that Apple has started using LEDs as screen illumination for a few of their laptops, and they hope to have all of their LCDs illuminated within a year or two (once their suppliers start making the units). They already use LEDs or similar tech on some iPod units, and the output is not objectionable to me in that use. I just hope it's not stroboscopic in a larger scale for longer periods of time.

Thanks for the update on the march of the LEDs.

I don't think they give off any UV radiation, but I'm not one to quote on that. I couldn't detect any strobe effect like I can with flourescents. It's just a very cool light, that's what I meant by harsh.

Blue, and cold looking. No softness to it at all.

Softness can be worked out in the diffusers or baffles, and so can color through lenses or gels. I know the public at large would rather not have to deal with diffusers or gels, but having worked with stage lighting before, I'm not bothered by the thought of it. ;-)




Sanity -> RE: incadescentr lightbulb- to be phazed out (12/18/2007 8:22:05 PM)

But the light source is too weak with LEDs, that's one reason it has to be its natural blue. It can't be baffled or filtered, and so that's why I originally referred to that cold / harshness problem as a "hurdle". The curved mirrors are for focusing the banks of LEDs so that they can have good effect. Once you start trying to diffuse it or soften it, according to what I was told, you rapidly lose brightness so that it all too quickly becomes unfeasible to use it (for task lighting) at all.

LEDs should actually emit over a much smaller wavelength range than most other light sources.  Hence, I wouldn't expect much in either the IR or the UV.  Also don't see any reason why they would pulse unless that's a function of how they're driven.  And last time I checked, there's a 60 Hz frequency off of incandescents that run off of household current- want to get rid of it?  Use a battery as a source.  I've got an LED flashlight that uses less amps and runs at 1.5V and is still much brighter than a Maglite at 3V and a higher amp draw.

Note- the original article I read just said that the new regulations for the light sources had to be more efficient than current technology- it didn't spec what the technology had to be.  Hence- claiming that gov't is "taking them away" is a bit off.  Come up with an incandescent that meets the regs- same as any other technology.  (I don't think it's possible, but hey- maybe I'm wrong.)  Nor did gov't take away the station wagon- the car companies developed the minivan instead- probably because it didn't have to comply with CAFE standards. 

I'm guessing- but do the folks that have trouble with LCD screens- also have trouble with laptop screens?  Because I'll bet that they don't run at a frequency- they're probably driven using DC.

Other than being a little mixed up here, I think we are doing OK. Slave, there is an element in your shower head that you can remove and again enjoy a real shower.

Let me go into the water thing. I do agree with the other poster about toilets. I had a cheap one and it sucked, required near daily cleaning and when I got tired of that it turned dark brown. It was an American Standard. Now I got a new one, for $160 and it has lasted the last few years with not much problem. When buying it I had a buddy with me who knows this shit, and we did research it a bit in the store. Square inches at the bowl water level is very important. And even though it only uses 1.2 gallons to flush, there are about three gallons pushing it. There is a diference.This is a high tech one, and in this case high tech seems to have worked out well.

Lightbulbs are the same way. Unfortunately mine make heat. I use high output bulbs and a dimmer. You can't use a dimmer on most of these newfangled ones. They last alot longer. Three 100 watters in the livingroom, but rarely turned up over halfway. They do last longer. That is a point I brought up, not here but somewhere else.

We bought a few flourescent fixures and some low energy bulbs for them. Put them in the basement. Now understand that I do look beyond the surface of an issue, it's just one of my curses, I am simply not allowed to be ignorant.

I said "These people take all day to make a forty watt tube only consume thirty two watts, but then the thing only lasts a month". What about the energy required to make a new one ? I said that, nobody else.

If we are truly to be energy concious and conservationist, we must look beyond our own electric bill. This is what people do not understand.

It is like law, respect for others' rights. People only think of themselves. And you fucking know it is true. Some of us would sacrifice 23 human lives to cut our electric bill. You know who you are.

If we are to think in terms of true conservation, we must think of the longevity of these products. It is not that we are against China's economy (where everything is built) it is that a true convervationalist will think in terms of what a certain action costs the environment as a whole.

Very few people do that. Most do not have the scientific knowledge to do so. That is because the powers that be wanted a generation of idiots. Wait until I turn the idiots against them. Teaching goes a long way in righting the problems of humamity, and I think most of us agree that the powers that be are a major part of the world's problems.

But the political aside, those high efficiency lights are great. They last longer, pull less juice and put out more light. Additionally some of them look really cool. But in my livingroon there are incandescents, on a dimmer. I don't use the full three hundred watts all the time, and when turned down they have a "warmer" glow.

However I do have a flourescent bulb at the top of the stairs, this after I got tired of changing it so many times. At the bottom of the stairs is what is known as an IQ bulb. This one will turn itself off after thirty minutes unless you turn it off and back on quickly, that disables the IQ function. It has been there for twelve years now.

I can't seem to find these IQ bulbs anymore. I recall there were several types, I got the timer type, but they had a dfimmer type, where you turn it off and on quick it dims. Way better than the old three way bulbs that were in vogue in the 60s and on. There was another type of IQ bulb IIRC, but I can't remember now exactly what it did.

If I could go back in time I would buy them all. I think it was a great idea, and I don't know how the company didn't succeed, and become a household name. Somehow they failed on the marketing end of it, or got bought out by the electric company. I would not let that happen.

You don't know me, you could put  million dollars in cash right in front of my face and I will not bat an eyelash. It does not impress me.

I'll tell you what else, the olman has this box, which is a combo caller ID and BLOCK box. We can block any number we want, and can block all "private" numbers that call here. It has a voice "Sorry we are not accepting calls from your number at this time" or "Sorry we are not accepting calls from blocked numbers at this time, please unblock your number and try again". To do that in the US of course you dail *82 before the number, but the little box does not give out those instructions.

You can't buy those little boxes anymore. You can't buy the chips for those little boxes anymore. You can't buy anything like those little boxes anymore. But that is OK, the phone company has a service for which you pay monthly, which does pretty much the same thing.

Let me say that again, so you can have a chance to understand (I know some do, but we must facilitate the others) THE PHONE COMPANY HAS A SERVICE FOR WHICH YOU WILL PAY EVERY MONTH THAT DOES THE SAME THING AS THE LITTLE BOX. Are you starting to get it ? That little box was about $30, tht is two months of privacy manager from SBC. We got one, and the only other person around here with one is my Mother.

We are actually switching the basement back over to regular light sockets, but we will be using the high efficiency bulbs. Four foot flourescents are junk now. They wrecked them. I bought a friggin case of them and each only lasts about a month. They start flickering and then fail to fire up. Very annoying.

There is nothing wrong with the fixtures because a new bulb/tube works fine. It all comes back to the shortsightedness of the engineering community and the governing body. When profits are paramount, We The People suffer. It is that simple.

So go ahead, phase out everythig that works, and replace it with things that do not work. We don't need to be bombed back into the stone age, we will be led back into the stone age by gross incompetence.

I do like those high efficiency bulbs though, the ones that screw into a standard socket. What is it called a T2 ? something like that.

If you happen to feel too good about the US, let me lay this on you. In Cleveland here LTV steel was a big employer, the biggest mill, but not the biggest company. Nobody gets that because Citibank was headquartered here until recently.

The employees at LTV steel stole so many lightbulbs that they paid union electricians to change every socket in the plant to a left handed thread. Sure the bulbs cost more, but you get to use them. When they used regular bulbs they were always running out no matter how many they bought, because people were stealing them. So at triple the cost for each bulb, they saved alot of money.

I don't have any idea what kind of response to expect from this, fuck it, gimme what you got.

If you need them for the heat though, then they by the laws of physics cannot possibly be "more efficient" because that's how efficiency is measured - "wasted" heat (or used energy). Government said ditch the station wagon, so everyone got vans and SUVs instead. If the government forces us to ditch the incandescent, then we'll just have to buy heaters!

I use an incandescent light bulb in my pump house in the winter, to keep my water pipes from freezing so that I can enjoy hot and cold running water. I also use one in my fruit cellar to keep it from freezing, and my UM and her friends use them to bake cakes, cookies and other goodies in her Suzy-Bake oven. Farmers use them in henhouses to hatch chicks... there are many uses, but environmental extremists are determined to save us from ourselves no matter the cost.

I used to enjoy family vacations as a kid in the classic station wagon too though, but the government took those away. Now they want my 4X4 truck!

...



While it is true that the standard AC current is supplied at 60 Hz, the incandescent bulbs "smooth over" the oscillations because of their inherent construction. The glowing metal filament, when compared to the current frequency, takes a long time to heat up and cool off. This is why incandescent bulbs suffer from no apparent flicker; the filament continues to glow during the current's "off" cycles.

Fluorescent bulbs are made with phosphors that react quickly to current oscillations; fast enough for some people to notice flicker. My understanding is that compact fluorescent bulbs are supposed to work around this by having an internal transformer that converts the 60 Hz AC into many tens of thousands of Hz. Good in theory, but with some bulbs, not so good in practice. If the tolerance of that internal transformer isn't just right, harmonics of the original 60 Hz current can occur, with the result being flicker.

I've tried the brands of CF available in my local area, and I can't be in the room if they are the only source of light. They still trigger my neurological symptoms in the same way as regular fluorescent tubes.

I'm hoping that there is some sort of efficient incandescent tech that replicates the glowing effect of the tungsten filaments. Perhaps ceramics would work; I don't know. I just don't know what I'll be doing should non-fluorescent tech not be ready within the time frame of this legislation.

T2 is a ballast type. The high efficiency bulbs you refer to are, I'm assuming, compact fluorescents.




Zensee -> RE: incadescentr lightbulb- to be phazed out (12/19/2007 5:01:35 AM)

You can get warm white LEDs, certainly as Xmas lights, so the technology is there.

Like I say, RGB LEDs means any colour you want and since they run on DC current there is no flicker.

And good riddance.  The damn thing doesn't make light- it makes heat- and light is a byproduct....


A common misconception. Even the term 'light' bulb is a misnomer.

They are actually darkness absorbers, and the heat is caused by removing the darkness from a certain area, allowing the light (which had previously been obscured) to be seen.

You know, i've got just enough Steampunk in my soul to really want a carbide lamp hanging off the front of my bike [:D] i just figure the days of legally buying carbide are numbered (it can explode! Oh noes! Homeland Security, save us!)

As stated, LEDs should not flicker. If they do, they've got a crappy AC>DC converter and aren't going to last long. LED-backlit monitors are not a good reference for this because the screen is constantly being refreshed (usually 60Hz, sometimes more). Try using an LED flashlight (battery-operated) in an otherwise dark room, and you shouldn't have any problem with strobing.

The technical problem with LEDs as room lighting is they're physically small, and they're very directional. They've got a relatively limited arc of illumination, which for makes them great for spotlight illumination, but lousy when you want to light a whole room. So far, the answer is arrays, which are expensive and create MTBF (Mean Time Before Failure) issues. The problem isn't solved yet, but you can be sure they're working on it.

Halogen lamps produce heat as well as illumination- substantially more heat than incandescents, as a matter of fact. They're just end up being more efficient in the net because they light a smaller visible spectrum. That would be a fine solution for the EZ-Bake oven and light-in-the-well-house issue, although not necessarily the reptiles.

i don't know from warm/cold/harsh ambient lighting, just like i don't believe there are really 800 different shades of wall paint between "white" and "yellow". i'm a guy. [:D]

One thing that can actually be an issue for household lighting is dimmers. You can't dim flourescents efficiently, same for LEDs. It seems to shorten the lifespan of halogens, at least in my ceiling fans. It irritates me that i can't use flourescents in my security lights because they have a low-voltage "dim" mode when the motion detector isn't active.

Oh, and if you have older flourescent fixtures, it's my understanding that you actually use more energy turning them on twice in an hour for a minute at a time, than you would leaving them on for an hour. Not sure if the newer ballast types have the same issue.

Stay light,

T, check out Lowes- it bought 1 or 2 gadgets- it screws in like a light bulb- you then place the bulb into it. it turns the light off in 15, and 1 dims the light to 0 after 30 mins. each were under $3. if Lowes dont have them, check on ebay.  another idea is to rig the power to plug into a timer. then plug in the timer- same effect.

the phone company loves to sell services.  im discusted with the modern world. im sick of computers phoning me.

im sick of endless commercials.

m sick of hearing me complain too.




pahunkboy -> RE: incadescentr lightbulb- to be phazed out (12/19/2007 6:26:45 AM)

halogyn uses a ton of power. touch the bulb and it breaks- -the oil from finger burns up the bulb.  they use this light in operating rooms. i have some fixtures with this type of bulb.  the fxtrures are cheap- but when the bulb breaks you may as well throw it all away. this lighting is pricey- i have 5 fixtures....that i have not installed- as -well it has not been worth it. not with my fix everything with a rubber band and paper clip approach




Archer -> RE: incadescentr lightbulb- to be phazed out (12/19/2007 6:26:53 AM)

Only one mention that I saw of the disposal problem for florecent bulbs.
They have in many cases mercury as a component of the waste product, they should not be disposed of in the regular trash, they need special disposal to be environmentally safe. So in the spirit of "Green" they simply transfer the polution from one waste stream to another. Less electricity demand, but disposal costs if disosed of properly much hgher than an incandecent bulb, and additionally if they are not disposed of properly they can poison the grundwater instead of the air.





samboct -> RE: incadescentr lightbulb- to be phazed out (12/19/2007 6:45:06 AM)

Sappatoti- - if you try to use a tachometer with an incandescent light bulb driven off AC current, it has no trouble picking up the 60 hz frequency.  I suspect that human eyes aren't so good at that- it's a 1/60th of a second.  I have a sneaking suspicion that the flicker of fluorescents is at a different frequency.

Dave-I pretty much agree with you-but a couple of other points I've picked up in my travels- LEDs effectively have a threshold voltage- you need to get to that potential before any light is emitted.  Thus, you're pretty much there when you said that you can't change the brightness of an LED- except that some sources "overdrive" the LED by pumping in more voltage to get more light out.  This does work, but also reduces the lifespan of the LED.  Some LEDs are more tolerant of this condition than others- hence there will probably be some type of brightness controls possible- alternatively it may have to be current limited- i.e. deliver 3V at 100 mAH- and only 1 LED fires up, add 200 mAH and the next one etc.

I'm not sure that LEDs are really the be all and end all of lighting- just to stir the pot a bit more, people are working on OLEDs as well (organic light emitting diodes)- which are already being commercialized in some small displays.  OLEDs produce a sheet of light- not much directionality or point sources there.  This would change light fixtures dramatically yet again.

Color balance is a real issue- incandescents mimic fire very well-and it's a light we're comfortable with.  Moving to bluer light tends to make things seem harsh and cold- people who like candlelit dinners tend not to like this light.  LED mfg are working on this issue.

Refresh rate of screens- IIRC- most laptop LCD screens work at changing the pixels that need to be changed- not changing all the pixels every 1/30th of a second or so.  The backlights- which is how you see the screen- are driven using straight DC voltage and hence should have no flicker.  If nothing else it's a useful experiment- to the folks that have trouble with flickering screens- does the problem persist on a laptop?

PanthersMom -> RE: incadescentr lightbulb- to be phazed out (12/19/2007 6:52:33 AM)

we changed all our light bulbs two years ago.  i prefer the flourescent lights to the incandescent bulbs.  they last longer and save me a few bucks a month.  i'd tell anyone who was considering the switch to do it.

Politesub53 -> RE: incadescentr lightbulb- to be phazed out (12/19/2007 8:38:57 AM)

Each source of household lighting has its own problem. Incandescent lamps give off a lot of heat. Fluorescent lamps have mercury and phosphor, so they need to be disposed of safely, normally they are just smashed causing contamination. Although they do give of UV`s the level is minimal and not dangerous to health. The way the light is emitted causes the problems, such as the flickering. Some of the new CF lights are being made small enough to install inside what appears to be a normal lamp, maybe these will be suitable for indoor use.

LED`s are not as efficent as fluorescents, producing an average of about 60 Lumens per Watt where as a flourescent is closer to a 100 lumens. Led`s also change colour as the temperature changes around them.

There is no doubt that the old style lamps do produce massive heat loss for the light they produce, and on the surface a fluorescent is more energy efficient. Take into account the extra energy involved both in manufacture and disposal though, and i wonder which one is the more "Global friendly" in the long term.

Its just been discovered that the cost of the small wind turbine kits that can be fitted to houses in the UK use more energy in production and installation than they will save. Maybe using solar panels for heating the home and hot water, combined with a traditional power supply is the answer. Once again its down to how much we are all prepared to pay.
