Recently I told about the smart LED lamps able to join automatically at approach of twilight, to change the color temperature 3000/4000K, to set one of three brightness levels or to smoothly change brightness without dimmer. Today I will tell about normal LED lamps of this brand.

The majority of LED lamps which I test and about which I write can be purchased only in specialized online stores, however normal buyers as a rule buy lamps in hypermarkets. I went to shops Auchan and Lerua Merlen, purchased 48 models of LED lamps there and tested them. Returned lamps back to shops as there is a possibility of return. From Lerua Merlen I will tell about lamps next time, today — 22 lamps from Auchan.

For brightness control of glow lamps the dimmer — the simple electronic device changing lamp brightness due to "trimming" of part of a sinusoid of mains voltage was very long time ago invented.
The glow lamp is simple, and the LED lamp contains the complex electronic circuit therefore with a dimmirovaniye there everything is difficult. Today I will tell what is done by dimmer, than they differ among themselves and as dimmiruyemy LED lamps in comparison with glow lamps at brightness control behave.

The first lamps of Gauss got to me for testing one and a half years ago. The majority of them had not really high color rendering index of CRI (72.8-75.7), and dimmiruyemy "candle" strongly flickered.
In new generation of lamps of Gauss these defects are eliminated — lamps have low ripple ratio of light and rather high CRI.
Recently I told about a powerful 12-watt lamp equivalent of the 100-watt glow lamp, today I will tell about three lamps candles with E14 socle.

I turned off the light, the computer "lulled", pulled out the refrigerator from the socket and looked what consumption of electricity shows the counter.
80 W. These are 700 KWh a year for which it is necessary to pay up to 3525 rubles!
In any modern apartment the network constantly included a set of the devices working in standby condition. Though they are also switched off, these devices consume a little energy, necessary for inclusion from the panel or the button.
