A good (normal in all parameters) LED costs from 250-300 rubles, but most will not be able to distinguish a good LED from a bad one.I had to test the bulbs of some office "Finish"(not so, but you will see and understand.I roll the lamp into the basement, turn on and I have the stripes in my eyes gone.I softened that it was fun with the pulse at the lamp.I checked the device and the record - 146%(no joke) coefficient.pulsation.I sell LEDs, I am interested in people to know how to choose the bulbs consciously.Why?) Because I only sell what I am ready to screw / install and install / screw myself home and my parents.Lifehack on the choice of LEDs:you will be in Ashan or Ikea or elsewhere, check.The phone in photo modedirect to the light source...see the bands (in most cases)...the width and frequency of these bands and there is an em...visualization of the pulse rate.One phone look at different bulbs...Especially different manufacturers in one price category and one power) Of course, you can not determine the digital value without experience, but see the difference - quite.If it is interesting, write in a comment...I will continue on the economic component)
You, shit, say what is better: wide stripes or narrow!!! The water is half water and so much zero!! to
