LED home lights: is it worth using?

Something you overestimated the price of LED lamps too much - even in our small town a 7 W lamp costs about 900-1000 rubles, and if you order from China, you can buy a 25 W (twenty five! Watt!) Lamp for a price of 2100 . And 9W - 1200 rubles.

Ichi,
Accurately and completely agree with you. The price tag is inflated at times. We have a price for LED lamps from 400 to 900 rubles.

It seems to me that you are too enthusiastic about "energy-saving" lamps (fluorescent lamps). To begin with, 100 W of incandescent is not like 1000 lm (this is a characteristic of 75 W of incandescent), but according to different sources from 1340 to 1630 lm (of course it depends on the characteristics of specific lamps, in fact from the manufacturer). Just a little difference, right? Somehow they didn’t at all mention that all the lamps (saving) somehow do not really like frequent on-offs and in the cold the light flux can drop significantly. LED lamps now, in essence, have just "come out" and are expensive, but over time all these LLs will leave the market because they will no longer be able to compete with the "grown-up diode". So the problems of diode lamps are temporary. And absolutely the “LED degradation effect” really amused, because of course it remains in a virgin state with a phosphor and nothing can happen to the ballast. The result is strongly biased.

The price tag is correct for good and famous lamps. Maybe you are talking about non-brand lamps like "China"?

The cost of a 100 W LED spotlight is about 15,000 rubles, each office lamp is about 7,000 rubles, a separate simple light bulb is 500 rubles, a tube lamp is 3,000 rubles.

I buy it myself, because it makes sense to come up with.

Subjectively, a 100 watt lamp shines like a 32 watt housekeeper.

It was assembled from two * deluxe * Poland (10 pieces were all burnt up spat) held for 10 years but twisted broke the flask, changed pure pieces of 54 pieces to 90 centimeters over bright LEDs. cost 108 hryvnias, applied 11.4 volts to them ((they really quickly burn out from high currents) you need a normal glass LED).

Not very pleased with the bluish light these 8 watts (11vat with trance) shine subjectively at 42 watts.

I have never seen any decent LEDs in terms of brightness and price.

Of the pros, a yellow ribbon may appear in the field of view, add 30 centimeters to the 4th strip.

No electromagnetic radiation 30 kilohertz.

No Flicker 30 kilohertz. No flicker 50 hertz (capacitor set 15 thousand microfarads.

And mercury is supposedly not used.

Plus a little hope that 10-20 years will work.

I wonder when all this was written? In the yard in 2012, the return of LED lamps is up to 150 lm per watt. Price - from 50 cents per lumen. By the way, I have not seen energy saving with a return of 100 lm / W and even for 100 rubles)))). If you compare, it is equivalent: Chinese CFLs (100 r each) have a return of not more than 50 lm / W and work no more than 3-5 thousand hours (or even less). Good Chinese LEDs already have a return of 100 lm / W, but there are more, they cost from 100 rubles for 150 lumens. New lamps are even cheaper and more economical. The colors are very different: from 2800 to 6000 K.
pc / recently purchased linear T8 60 cm 700 lm 4000K (in Armstrong luminaires) at 490 r - they consume 9 watts, 18-watt light boxes shine on the eye as well. At the same time they light up immediately, do not flicker and are not afraid of low voltage in the network. Let's see how long they will last (in general, I started using LED lamps 3 years ago - not a single one has burned out yet).

Another important point, mentioned only in the commentary and then in passing: if you drop the luminescence, you get mercury vapor (a little, but still harmful), and if you drop the diode ... nothing will happen - if you don't have a bulb, it won’t even break .

Sellers also used to say (I did not check it myself) that diodes are not afraid of greasy fingerprints, while they write on all fluorescent fingerprints, they say do not touch the flask with your fingers.

Fingers should not be touched not on fluorescent lamps but on halogen lamps. You can touch the fluorescent ones - nothing terrible will happen.

PR of expensive Medved bulbs ... I buy from auction www.ebay.com these LED bulbs for a penny ...
http://www.ebay.com/sch/i.html?_sacat=0&_sop=15&_nkw=e27+smd+5050&_frs=1

LED lamps cost a penny, do not fool people with a china lamp at 900 lumens cost 200 rubles, which fuck 1300 for 300 lumens.

I bought several types of cheap lamps from China, put them in my apartment instead of energy-saving, as a result, there is really no saving, moreover, they shine worse (narrowly focused), and when you read a book you often close objects with your shadow, if you look at the LEDs themselves they blind, but do not really light. One lamp died in the bathroom after two weeks, the other after 2 months (I didn’t turn it off on purpose) in the corridor changed its color, it began to shine yellow and the brightness dropped by about 40%. I took it to work and measured it with an ordinary AC power meter. The best example, with an output power of 7 W (it is written on the lamp, and the number of LEDs there are 7 pieces of 1 W each) showed a total power of 19 W, and cos (F) - 0.38. Compared to energy-saving 15W, it consumes 18 watts and it illuminates much better. Therefore, an LED lamp that is really high-quality and reliable will be expensive and exceed even more than 150 lm / W with power consumption. Because LEDs, so that they do not degrade ahead of time, need to be cooled and their temperature should not be higher than 60 C i.e. high-quality radiator, you need a high-quality current source for them, a well-thought-out design and a diffuser for a larger area of ​​illumination, rather than shining a bright spot in one place, and I almost forgot the brand-name LEDs of course. And they will always be cheap analogues, only to the point of them, some show off and money down the drain!

I already have the whole apartment lit by LED lamps. Kitchen 12m2 - 6 lamps of 6W each. Room 20m2 - 8 lamps of 6W each. Bathroom 1 lamp -10W. Toilet 1 lamp - 4W. Hall 8m2 - 5 lamps 3W.
For 1.5 years of use, neither the lamp nor a single LED in the llama burned out.

What is the point of this article? Promote energy saving fluorescent? What for? It is clear that the future lies with the diode. Prices, again, where are the author digging such? We must divide by 10 and get an adequate price for the LED lamp.
Changed everything in the apartment to the LEDs. In one room for more than a year 6 pieces of 6 Watt have been lit in the chandelier. A lamp brought from China has been lit in the toilet since 2010 - full noname, but even everything is on. Yes, I even put a 2 Watt special in the refrigerator, I don’t know why, but they cost me cheaply, since I sell them myself.

In 2014, a 7 W LED lamp in our city costs 300 rubles; 10W -340 rubles, the usual incandescent 60W an average of 15 rubles. Given that in Russia, winter lasts longer than summer, therefore, there is more dark time of the day per year and it is more profitable to buy diodes!

LEDs have a huge minus against incandescent lamps - a narrow emission spectrum (like a laser). In incandescent, the spectrum is almost like in the sun: from infrared (thermal) to ultraviolet (in halogen). All living things do not respond well to such light; one can find studies of lamps and their effects on animals in the internet. Even ultra-expensive telly with LCD backlight began to do with a three-color backlight for more natural white and black. So think what is more important - saving or health (the eye), and energy-saving luminescent - you do not see the pulsation of the RF converter in them, but the brain feels!

Michael, there are several manufacturing technologies, which gives a different spectrum.

Michael,
I completely agree with you !!
This is already a completed stage !!
Indeed, these energy-saving light bulbs are unhealthy! I experienced it in my bitter experience. At the beginning of 2000, the work was, as they say there were grandmothers and I went to the store and saw these very expensive bulbs, the seller rubbed me that they are expensive but very economical. And I really believed him and immediately bought 30 pieces !!
Arriving home, he began his family saying that your father bought expensive light bulbs. And after 2-3 months, I found that with my eyesight something was wrong !! The doctor made it clear to me that everything will be in order if I urgently throw out these same bulbs. And a lot of time has passed since then, as I am painfully related to this issue. Mikhail, a literate person in this part, and he perfectly proved that health is much more expensive than the money that we supposedly want or think to save !!
All this is nonsense!
They are really good for industrial use, in workshops, in garages, at train stations and airports, but not for home use.
If I cheated on someone from businessmen, then I'm sorry = I wrote just a fact !!

For several years, I have all the lamps in the house energy-saving (mercury). Where you need brighter light - 32 watts (equivalent to 150 watts of incandescent light) In the hall there are 2 pieces, kitchen 1, in the second room 1. In the bathroom 4 pieces 9 watts. In the hallway 2 pcs 9 watts. For 3 years, only one 32 volt burned out. I am satisfied, I do not feel any damage to the eyes. Above the computer table is also 32 watts.
In srkkter 2 old tubes of 20 watts in the nightlight 1 pc 7 watts.

This article is initially extremely bad. For example, what is only a description of the characteristics of color temperature - an incandescent lamp 2800, energy-saving 4000, LED 5500. While energy-saving and LED lamps are produced with very different this parameter. It can be seen that the person who wrote the article is extremely illiterate. I always bought energy-saving (luminescent) 2800K and no more. Now I buy LEDs with the same color temperature for rooms and 3000K for the kitchen and hallway. Over time, the article generally deserves immediate removal.

I can only say one thing, something that an electrician has encountered in his practice. Any fluorescent lamps, including energy-saving ones, contain mercury inside (and the phosphor is also not a gift). Yes, the amount of mercury is small - well, there are 2-3 grams. But the danger is not that you will break the lamp if your hands are crooked, but that sometimes the lamp base is depressurized during operation, the lamp burns out, mercury vapor scatters all over the room, and there are enough of them, according to DIN Institute findings European standards for a very slow but sure mercury poisoning, we have small rooms. Alternatively, you can throw everything out of the room — furniture, things, strip the walls, floor and ceiling to concrete, and then restore everything again and buy new furniture. Yes, this happens very rarely, but, being in an adequate condition, drag a grenade into the house? Even if one out of 10,000 accidentally explodes, then why not you? Well, manufacturers and sellers of LED lamps fool people differently. No one warns buyers that under the conditions of our realities, in our electric networks, LED lamps often serve less than incandescent lamps if an overvoltage protection relay is not installed at the entrance to the apartment.

AnatolyI do not agree on the expense of LED lamps. I was convinced from personal experience that LED lamps are reliable - now they are the most reliable of all available types of lamps. Modern LED lamps are designed to work in a fairly wide voltage range. Moreover, they, in comparison with other lamps, are the least vulnerable to voltage drops.

Incandescent bulbs are now doing very poor quality - they had to change several bulbs a month around the house. Put LED - I forgot what it means to change the lamp. LED lamps paid off already in the first months, as I bought LED lamps once, and I had to buy several incandescent lamps a month. Housekeepers (compact luminescent) also did not take root, as they often failed.

I recommended to relatives and friends to purchase LED lamps - everyone is happy with their reliability and economy.
