But the same old jack plug in the computer, but everything is normal, but the strip will issue "hissing" sound. Supposedly the lamp power is smaller than a computer, this is how to return a responsibility? I think baidu has said strip contact.: Lights flash that strip poor contact, the lamp power is small, so can't hear hissing "sound, the computer power is relatively larger, current is big, hissed." sound that strip poor contact; If you have the tools to open the strip to see whether the contact deformation, the whole connection piece, make can remove plug well, your problem is solved.

Surface light is simple, LED color performance, add a dustproof lampshade is, sometimes with grind arenaceous chimney, better astigmatism. Besides, desk lamp, desk lamp is the design standard of infinite close to the sun, because artificial forever than nature. So now the LED lamp like stressed without glare No stroboscopic, no radiation it is for this reason, who is more close to the sun, who is better.

Q: Consult the LED rechargeable lamps not to save battery What do I do: This is because the battery is broken, the solution has two: 1, the replacement lamp battery. 2, connect the power charger use desk lamp.

Q: Do LED lamps really protect your eyes?: Just a slogan, not for a long time on the light.If choose when must pay attention to the surface light source

Q: The voltage of the LED lamp is about how much: Like to see the instruction manual. General desk lamp is 6 v or 12 v (lead-acid battery). 3.6 V or 7.2 V (lithium ion battery). 220 plug into mains, after a step-down rectifier transform into direct current, lit LED lights, and recharge the battery (losing electricity state). The working voltage of a single LED lamp is between 3.2 3.6 V, usually series after parallel. If you don't know how much is the voltage, disassemble the lamps and lanterns, count you know leds in series voltage
