- Q:The advantages and disadvantages of LED the desk lamp that shield an eye
- 4) light source does not contain toxic heavy metals such as tungsten, mercury. The tungsten filament in the semiconductor light source without them no fluorescent lamp, energy-saving lamp of mercury inside. (5) safety. 12 v low voltage dc power supply; No easy broken glass parts, ensure the safety of users. 36 v is the minimum voltage, can feel the body is less than 36 v power supply is safe to human body. Don't even need to 3 c certification. Dc power supply, to eliminate the high frequency alternating current (ac) of electromagnetic radiation pollution.

So for the average person can answer 0 degrees. Do you have any questions? Can you give me a message!
- Q:How many volts 4 w power led desk lamp
- Depends on what kind of, have 220 v, also has a charging V6, 12 v.
- Q:Whether the LED desk lamp, luminous points: two guide plate and the patch?
- Yes, with the guide plate is commonly known as the "light", luminous uniformity is better than patch directly on the shiny surface, but the cost is much higher.
