Q:High-power LED the lamp that shield an eye more appropriate
1 year than energy-saving lamps use 80 KWH, take 40 yuan, really want to save money a lot. And national electricity resource gap is big, also do not encourage you to use white definite lamps. 6 w LED is very bright, but a little bit far distance of illuminance are not idle, half reading needs illuminance in 300-500 lx, far from textbooks some big power, small power from the textbook, with your eyes feel comfortable as well.
Q:Led lithium battery lamp, rated input current 0.5 a
Charging current is a bit big, easy to cause the battery heating, out in the end. Or the cause of desk lamp current charging circuit for burning.
Q:Desk lamp good still tube of good to buy LED strips?
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:The LED current problem? LED lamp current problem?
USB interface receive computer desk lamp, computer burden is heavy, easy to addled computer. Besides, desk lamp, desk lamp, 1 a current lamp current 190 ma, bad, or move a few desk lamp table lamp lights die.

Q:Led and energy-saving light which good? To solve the
3, energy-saving lamp power consumption is too large. White LED power consumption is only 1/10 of incandescent lamp, energy-saving lamp of a quarter. 4, energy-saving lamps, easy damage, short service life. Led lights, longevity life can reach more than 100000 hours, can work at high speed. Energy-saving lamps if frequent start or shut off the filament broken will be dark soon. 5, a single LED low power, and energy-saving lamps to achieve the same brightness require multiple parallel. 6, the led light color rendering index is low, under the led light display color no real energy-saving lamps
