X-Flash Smart Bulbs

by admin

Under the brand name X-Flash is produced by 154 models of LED bulbs Among them are seven unusual models called smart bulbs. I tested four lamps with a color temperature of 3000K (the other three models have a color temperature of 4000K).

Various X-Flash smart lights can :
– automatically turn on at dusk;
– Change the color temperature 3000/4000K;
– Set one of three brightness levels;
– to change the brightness smoothly without a dimmer.
The first model is. XF-E27-OCL-A65-P-12W-3000K-220V Item No.: 46645 AutoON (4000K color temperature variant – XF-E27-OCL-A65-P-12W-4000K-220V Item No.: 46652 ).

There are red photosensor windows on both sides in the base of the lamp. When the lamp is exposed to bright light, it does not light up. At dusk, the lamp lights up and stays on until the light is bright again. The lamp has a 1.5 minute restart delay so that it does not react to accidental dimming. I measured the threshold for the lamp to turn on. It turns on when the brightness of the ambient light becomes less than 100 lux.
The second lamp is. XF-E27-TCL-A60-P-8W-3000/4000K-220V Item No.: 46706 2-Color Capable of changing color temperature.

When you turn it on, it always shines a warm 3000K light. If you quickly turn the lamp off and on again, it starts to glow 4000K white. If you turn it off and on again, it is 3000K again. After it has been turned off for a long time, the state is not remembered. Actually there are two groups of LEDs with different color temperatures inside the lamp: either one or the other one will light up.
The third bulb is. XF-E27-TLL-A60-P-10W-3000-220V Ref: 46669 3-Step Dimming (color temperature variant 4000K : XF-E27-TLL-A60-P-10W-4000-220V Item No.: 46676 3-Step Dimming ).
The lamp has three brightness levels – 100%, 50%, 20%. When you turn it on, it shines at maximum brightness. The first time you turn it off and on quickly, the brightness is 50%, the next time it is 20%, the next time it is 100% and so on in a circle. It does not remember the state after a long period of turning off.
The fourth bulb is. XF-E27-GCL-A60-P-10W-3000K-220V Art. no.: 46683 Gradual Dimming (color temperature variant 4000K : XF-E27-GCL-A60-P-10W-4000K-220V Item no.: 46690 Gradual Dimming
When the lamp is switched on, the brightness increases to the maximum brightness in 10 seconds. If you turn the lamp off and on again quickly while the brightness is increasing, the brightness will be fixed at the current level. If the lamp is switched off and on after it has reached maximum brightness, it will start increasing the brightness again from minimum to maximum. The lamp can be immediately switched to its minimum brightness (8% of the maximum brightness) by turning it on, turning it off and then on again. The state is not remembered after a long period of switching off.
I made a little video to clearly show how the smart lights work.

I tested the bulbs with the instrumentation Viso LightSpion and Lupine The lamp "XF-E27-TCL-A60-P-8W-3000/4000K-220V Art: 46706 2-Color" takes two lines in the table – this is its operation in 3000K and 4000K modes.

All the lamps work correctly with light switches that have an indicator (they don’t flash or burn when off), they have excellent light ripple levels and good color rendering indices. The lamps have a comfortable light, slightly whiter than incandescent bulbs. The lamps can be recommended for residential use.
The measured luminous flux level of the first two lamps is slightly lower than declared, but in the requirements GOST P 54815-2011 fits: the luminous flux of the first lamp is 92% of the nominal, the second – 91 and 99% (in different modes), and the State Standard measured the initial luminous flux of the LED lamp should be at least 90% of the rated luminous flux. The measured luminous flux of the third and fourth lamp was higher than the declared.
The XF-E27-TLL-A60-P-10W-3000-220V Art. no.: 46669 3-Step Dimming is the brightest bulb. It gives 909 Lm which corresponds to an 85 W incandescent lamp. Measurement result :

All models of X-Flash smart bulbs cost 599 rubles.
Auto-dimming bulb is good for street lighting and for well sunlit rooms. It may not be suitable for dark rooms like porches because there may not be enough daylight to activate the sensors and the lamp will be on around the clock.
The lamp with two color temperatures is perfect for those who do not know what color they are more comfortable with or for those who trust the theory that warmer light relaxes you and cooler light stimulates activity.
Dimming lamps will be useful in the bedroom and living room. They can be dimmed before bedtime or when watching TV.
In addition to the X-Flash smart bulbs, I tested 10 regular bulbs of this brand. For the results of this test, as well as all the other results of my LED bulb tests, see lamptest.ru
