Infinitely dimmable USB mini super bright LED light based on SGL8022W

USB touch light based on SGL8022W, ultra-low cost!
 
The operation is simple. Touch dimming
only requires an old low-current 5V USB charger.
It is very convenient for home use or taking out.
 
The LED uses 2835 3V 200ma specifications.
Use:
connect the power supply, touch the tail with your finger and the light will slowly light up. When the brightness reaches 90%, touch it again to slowly turn it off.
Touch the tail when it is off. When it lights up to the required brightness, touch it again to save the brightness setting and turn it off. Touch it again to turn it on and it will gradually brighten to the set value.
When it is on, touch and hold it without letting go. It will gradually lighten or darken to the brightest and darkest point. During this period, let go when the required brightness is reached and the corresponding brightness will be saved.
The saved brightness becomes invalid after a power outage and needs to be reset.
Note: When you buy 8022w in some tb stores, they will deliberately send you other models of 8022 and tell you that it can be used. If there is no problem with the welding of your lamp, but the lamp is flickering, be sure to check the chip silk screen! ! !
 
Note: If you want to be able to bend freely like a desk lamp, search on tb and buy a USB lamp extension cable for less than 5 yuan to achieve a better experience.
