Q:Desk lamp good still tube of good to buy LED strips? Search light tube usually can use a few years need to change?

Good light source directivity, on-demand lighting, as an emergency lamp is better. 2, small volume, the LED is basically a small chip is encapsulated in epoxy resin, and so it is very small, very light. 3, intensity of illumination is enough, meet the demand of your general illumination.

Q:New LED lamp USES "magnetic -" the voice from time to tome, how to eliminate the noise?

Q:With 10 v charger with 6 v rechargeable batteries used at the same time, that is used when mains mains, there is no mains automatic conversion electric battery. Three light bead is in series or parallel good? Add how much resistance? Step-down to to the charger? If I want the dimmer, should how to do, had better have circuit diagram

What is your 6 v battery batteries? Small battery (battery)? 10 v charger to see what the battery charger, if the battery can work with, if nimh electricity or lithium electricity will reduce the voltage. How much is the pressure light bulb? It is best to parallel, serial word broke a are not lit up. Add how much resistance depends on what you use the lamp, or led. The dimming added potentiator current limiting. How to do is very simple, still with the figure? Charger and battery, lamps (and) series of potentiometer.

Q:The LED lamp is bad for your eyesight?

Hello, LED light source is green light source, the use of dc drive, so no energy-saving light stroboscope, can effectively prevent eye fatigue, but high color temperature of LED lights, there will be a blue light damage problem, so suggest to choose warm white or natural white LED lamps, don't choose inferior with pressure drop resistance capacity or high-pressure direct driving leds!

Q:The led lamp low-grade why current sound

1, if appear this kind of current sound, then you buy the desk lamp of more times. Inside the power module is not very good. 2, the better the desk lamp of all is the use of constant current power supply, ensure that the service life of the lamp is longer.

Q:New LED small rechargeable lamps filled with electricity or running

First power consumption, basically see your battery is what material, have the ability to remember. If nickel-chromium batteries will be used up first, then charge, you can't have the to lithium ion.
