X-Flash Smart Light Bulbs
Under the X-Flash brand, 154 models of LED lamps are produced. Among them are seven unusual models, called smart lamps. I tested four lamps with a color temperature of 3000K (the other three models have a color temperature of 4000K).
Various smart lamps X-Flash can:
')
• automatically turn on at dusk;
• change the color temperature 3000 / 4000K;
• set one of three brightness levels;
• smoothly change the brightness without dimmer.
The first model is XF-E27-OCL-A65-P-12W-3000K-220V Art .: 46645 AutoON (version with color temperature 4000K - XF-E27-OCL-A65-P-12W-4000K-220V Art .: 46652 ) .
From two sides in the base of the lamp there are red windows of photo sensors. When a bright light enters the lamp, it does not light up. At dusk, the lamp lights up and lights up until the lighting becomes bright again. The lamp has a 1.5-minute re-start delay so that it does not react to random blackouts. I measured the threshold of the lamp. It lights up when the ambient brightness is less than 100 Lx.
The second lamp - XF-E27-TCL-A60-P-8W-3000 / 4000K-220V Art .: 46706 2-Color can change the color temperature.
When turned on, it always shines with a warm light of 3000K. If the lamp is quickly turned off and on again, it will begin to shine with a white light of 4000K. If you turn it off and on again, again 3000K. After a long shutdown, the state is not remembered. In fact, inside the lamp there are two groups of LEDs with different color temperatures: they turn on either one or the other.
The third lamp is XF-E27-TLL-A60-P-10W-3000-220V Art .: 46669 3-Step Dimming ( 4000K color temperature option: XF-E27-TLL-A60-P-10W-4000-220V Art. : 46676 3-Step Dimming ).
The lamp has three levels of brightness - 100%, 50%, 20%. When turned on, it shines with maximum brightness. At the first fast shutdown and on, the brightness becomes 50%, at the next - 20%, at the next - 100% and so on in a circle. After a long shutdown, the state is not remembered.
Fourth lamp - XF-E27-GCL-A60-P-10W-3000K-220V Art .: 46683 Gradual Dimming ( 4000K color temperature option: XF-E27-GCL-A60-P-10W-4000K-220V Art .: 46690 Gradual dimming
When turned on, the lamp gradually increases the brightness to its maximum in 10 seconds. If the lamp is quickly turned off and on again in the process of increasing the brightness, the brightness will lock at the current level. If the lamp is turned off and on after the set of maximum brightness has been reached, it will again begin to increase the brightness from minimum to maximum. Immediately turn on the lamp to the minimum brightness (8% of the maximum), you can, if turned on, off and immediately on again. After a long shutdown, the state is not remembered.
I shot a small video to clearly show how smart lamps work.

I tested the lamps using the Viso LightSpion and Lupine instruments. The lamp “XF-E27-TCL-A60-P-8W-3000 / 4000K-220V Art .: 46706 2-Color” occupies two lines in the table - this is its work in 3000K and 4000K modes.
All the lamps work correctly with switches that have an indicator (they do not blink and do not light when turned off), everything is fine with the level of light pulsation and good color rendering indices. The light of the lamps is comfortable, slightly whiter than that of incandescent lamps. Lamps can be recommended for residential use.
The measured level of the luminous flux of the first two lamps is slightly lower than stated, but the requirements of GOST R 54815-2011 fit in: the luminous flux of the first lamp is 92% of the nominal, the second is 91 and 99% (in different modes), and the measured initial luminous flux as GOST LED lamp must be at least 90% of the nominal luminous flux. The measured luminous flux of the third and fourth lamps was higher than stated.
The brightest was the lamp XF-E27-TLL-A60-P-10W-3000-220V Art .: 46669 3-Step Dimming. It gives 909 Lm, which corresponds to an 85-watt incandescent lamp. Measurement result:
Comparison with incandescent light in the interior. All photos were taken in manual exposure mode with a fixed white balance setting (3500K, ISO125, F1.8, 1/30). At the time of photographing the voltage in the network was 225 V.
Three levels of brightness adjustment.
Lamp with auto power on XF-E27-OCL-A65-P-12W-3000K-220V Art .: 46645 AutoON.
Lamp with two color temperatures XF-E27-TCL-A60-P-8W-3000 / 4000K-220V Art .: 46706 2-Color.
3000K mode.
4000K mode.
Lamp with continuously adjustable brightness XF-E27-GCL-A60-P-10W-3000K-220V Art .: 46683 Gradual Dimming.
All models of smart X-Flash lamps cost 599 rubles.
The lamp with auto-switching is suitable for street lighting and for well-lit rooms with sunlight. For dark rooms, like entrances, it may not be suitable, as daylight may not be enough to trigger the sensors of the lamp and it will burn around the clock.
A lamp with two color temperatures is perfect for those who can not decide what color of lighting to them is more comfortable or for those who trust the theory that a warmer light promotes relaxation, and a cooler one stimulates activity.
Lamps with adjustable brightness will be useful in the bedroom and living room. Their brightness can be reduced at bedtime or while watching TV.
In addition to smart lamps X-Flash, I tested 10 ordinary lamps of this brand. The results of this test, as well as all the other results of my tests of LED lamps, look at lamptest.ru .
