China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

White or yellow for eyes health? If the only look at the books, or an incandescent (commonly known as the electric lighting) is good, if is to look at the pictures, color pages, or rare earth fluorescent lamps (energy-saving lamps) that good. Incandescent light bulbs 60W, do not buy too much power, power is too large, too bright for the eyes.

Incandescent lamp that emits light yellowish, yellow light contrast is relatively high, which is auto fog lamp why is yellow one of the incandescent lamp and fluorescent lamp difference is incandescent lamps flicker, and fluorescent lamp is high-frequency flashing, blinking the eyes for a long time will feel tired eyes incandescent lamp dimming, is not recommended to use a dimming of, because once the dimming will appear the phenomenon of scintillation.The reason for this is that the now dimming circuit is electronically controllable silicon dimming, although convenient, but supply to incandescent lamp has become a pulsating direct current, so will flash. Therefore, adjusting the brightness or a replacement lighting power better. For example, do you think too bright, change a power smaller lighting, and power is not the more the better, according to your actual need to buy the right is best buy Lighting and lamp.

The best is the bulb frosted, if is a fluorescent lamp, lamp is the best grinding sand (is a frosted cover the light shade, from the outside can not see the lamp) grinding sand helps to reduce the flicker of rare earth fluorescent lamp is the advantage of high color temperature, true color reproduction, if you see the content (e.g. photos, pictures) for fluorescent lamps, which can not avoid color distortion, dimming lamp is the incandescent lamp based on the principle, control of light intensity by adjusting current through the incandescent lamp, the current commonly used bidirectional thyristor regulation, by adjusting the trigger angle control voltage to control the current through the load; the energy-saving lamp is generally used for the compact fluorescent lamp electronic ballast, light color have a look will know, the electronic ballast of voltage variation has certain adaptability, reduce the voltage within a certain range, the light can remain unchanged. The general principle of electronic ballast is the first AC rectifier, then the DC voltage into high voltage power on a fluorescent lamp through the high-frequency oscillator, just a little attention will find energy-saving lamp light is not flashing, and fluorescent lamp using electromagnetic ballast has proved: flashing, fluorescent lights in the front swing fingers, see the shadow that multiple finger lights were flashing and dimming, dimming principle leads to high harmonic circuit, the rectifier circuit filter failure (electronic ballast is designed according to 50Hz sine wave), resulting in a high frequency oscillating circuit is not normal, so easy to damage, it is best not to use energy-saving lamps in tune light lamp. Not to use, it is best to adjust the light knob to the maximum.
