- Q: The LED lamp how to realize the function of adjustable brightness and color temperature?
- Dimming color LED to absorb dome light, it is within 2 the output of the road. All the way to warm light color temperature (3000 k), all the way to cold light (white, around 7000 k color temperature). Each is independent of all the way. By giving each different brightness, all the way to the whole lamp color temperature adjustment and brightness adjustment. For example, A road is warm light, color temperature 3000 k, but only 10% of the full bright, brightness and B road is cold light, brightness is only 40% of the full bright, so, blending the color temperature in light body may be only 5000 k (there was A little warm white is not very cold, white). That is to say, the real dimming color can calibrate the brightness and color adjustments.

Actually charge much less charge will only affect the service life of lead sulfate in lamp battery, lead acid battery is made of memory effect, its charge number is directly related to its service life, so full of as well. But don't forget to pull out 24 hours, so there will be no safety accidents. 2, charge how many hours to charge, charge is not enough time to influence? Already answered above, will only affect the life. Influence is very big. Suggest you fill 8 hours as well.
