- Q:LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
- Energy-saving lamps, color rendering index above 80, it has a variety of color temperature. Read a book, I suggest to use 4000 k; High color temperature advantageous to concentrate, but Dazzling; Low colour temperature of concentrate. When reading a book, lamp writes a 1.5 meters, 300-350 lux. So-called energy-saving lamps, is high frequency, otherwise, it is not energy-saving lamps.
- Q:I am doing an LED desk lamp,

- Q:Pupils to do homework with good desk lamp is yellow light or white light is good
- It is recommended to use warm color fluorescent lamp LED cold light source, the spectra of blue-green color is bigger, have very strong stimulation to the eyes, time for a long time easy to cause eye fatigue; The traditional light bulb, heat source, the spectral distribution uniform, smooth color slants yellow, soft light, but the brightness is not enough, time is long can also cause visual fatigue; Fluorescent lamp (stick), according to a different phosphor powder materials can be divided into cold light warm light, cold light lamp color white or bluish, high light, but light stimulation, according to a visual fatigue; Warm yellow light line, but the brightness of the fluorescent lamp is stable, the light is downy, using the most suitable for reading

- Q:Children lamp good choice led lamp is better
- Use LED lamp is better. Save electricity, no flash, the light is downy. General energy-saving lamps such as uv radiation, and there will be a stroboscopic.. LED there is no such as uv radiation, there is no stroboscopic, longer life, count was more stable, and quick response.
