The ratio of the power of lamps of various types

The article is good, I liked it for determination with the choice of lamps is suitable, but I would like to ask the author to cover the problem of the impact on vision of each of the lamps examined. Nowadays, LED lamps have begun to appear a lot, but no one illuminates the effect of the light spectrum emitted by them on eye health.

1 The luxmeter measures the average over a specified period of time.
2 CFL does not bring any savings, since Chinese CFLs from declared light values ​​to natural are, as they say, two big differences. Yes, and rarely serve more than 1 year. Although I will say in favor of branded. I had a Phillips lamp of 20 watts - I bought it in the mid-90s. I worked in my kitchen for 20 years! Flared up with a delay and smoothly. Color rendering somewhere around 3000.
3 And now about the LED lamps. First, the principle of work. It is powered not by a constant smoothed current but by a PULSE high-frequency. What does it mean? and the fact that a larger instantaneous value of the luminous flux can be squeezed out of the crystal than with direct current. How does this affect vision? Flicker is very noticeable on moving objects! I have a vinyl player and the strobe is clearly noticeable. Yes, our eyesight is inertial, but the light is perceived as unpleasant. Also, in my corridor there’s a night light with a photocell, so it immediately responds to 1 incandescent lamp turned off, and to 2 LED Maxus of 10 watts, it first blinks, and after a while it calms down and turns off.
Draw your own conclusions

I agree with the author. We felt the difference between an incandescent lamp and an LED on your own wallet. We changed all the lamps in the apartment to LED and began to pay much less. On average, around the year, all the costs of the lamps paid off, and they all continue to work.

I have such a question, the article says that in the future, the law will ban incandescent lamps. But if an ordinary lamp costs 16 rubles, then the energy-saving 100 rubles. Again, the law is not in favor of the people. By the way, energy-saving very quickly burn out.

Let me make my five cents. For several years, the apartment used incandescent lamps, LED and energy-saving at the same time. So, the first and third constantly burn out. A LED pleased. So the future is definitely theirs!

It's time to switch to LEDs. Their light is much softer, and the savings are significant, if you take the charge for electricity - almost twice. It is worth spending money on a branded product so that it not only pays off, but also reduces the subsequent costs of electricity.

The measurements are not entirely correct. An incandescent lamp and a compact fluorescent lamp illuminate everything around, i.e. almost 360 degrees, only the base interferes, and LED only 120 degrees, that's where the gain comes from. Take a reflex lamp and compare.

Natalya87,
Almost half the fee for the consumption of e / energy? That is, you have absolutely no energy-consuming appliances (kettle, electric stove, condo, etc.). Tell me, please, about the spectrum of non-incandescent lamps, about the dangers of their pulsating light (fluorescent and LED lamps are practically inertia-free) on vision. Olga, From the classic of V.V. Mayakovsky "Listen! If stars light up in the sky, then someone needs it!".For example, I had an incandescent lamp in the corridor (where frequent on-off) worked for as long as 20 years, only because it was fed through a trinistor scheme for smooth ignition (I am a radio amateur). Superbright LEDs operate at maximum currents (therefore, heat sinks - “radiators” are installed in such lamps) in a narrow emission spectrum. For thousands of years, the human eye has adapted to a wide spectrum of solar radiation. But the task for marketers is to convince people to "keep up with the engine."

I still do not understand. The article is bloated, as for a thesis. In short, how to determine the lamp in the old 100.150 and 200 watts. What are they comparable now in terms of illumination? Now what do not you take. It seems less light gives out than before a conventional 100W incandescent lamp.

Thanks Andrew for the useful article. I would like to add a comment from Protsenko Roman to your article: LED lamps sell with cool white, white, warm white, and other light. Perception is comfortable for a person’s eyes, warm white light close to an incandescent lamp. Often people buy cold -white glow, designed more for industrial premises. I recommend everyone to carefully read the packaging. Thank you.
