We buy a good quality LED Tube, you have to select a good cost LED fluorescent several parameters need to know
1: Luminous brightness
A Philips brand 46W (with rectifier power) fluorescent light is about 1600LM, made a?‹a?‹of 1400-1500LM.
2: Power
Know brightness, you have to ask about power, the same brightness, the smaller the power, the higher luminous efficiency, energy-saving, the better. Ordinary 46W fluorescent lamp, 15W-LED fluorescent lamp can be completely replaced.
3: LED chip brand
LED chip direct relationship to the life of the LED fluorescent light fades, the LED chip production base worldwide, 80% are concentrated in Taiwan, more famous chip wafer manufacturers, Chi Mei. Domestic several LED chips, cheap, brightness almost than with Taiwan, but the quality stability is no way than with Taiwan.
4: LED drive power
LED drive power is equivalent to the heart of the LED fluorescent lamp, with the poor, lamp light a few days to hang it. A good LED power should achieve greater than 90% efficiency, power factor greater than 0.95, are long-life electrolytic capacitors used in high temperature domestic brands (electrolytic capacitor life of more than 8000 hours, temperature 105 ° called long-life products, electrolytic capacitor life depends on the use of the environment, every 10 ° temperature drop, double its service life)
These parameters are optional LED Tube factors you have to consider?
