1.Advantage:
LED fluorescent lamp has 10 main advantages over fluorescent lamp:
（1）High shine efficiency: The shine efficiency of fluorescent lamp is 50-80 lm/W, while the shine efficiency of LED fluorescent is over 100 lm/W, this data is higher and higher in the future, the gap between these two different lamp is 2 times, it will reach 3 times in the near future.
（2）High efficiency: The degree of fluorescent lamp is 360 degree, as a result the waste of some direction of the light. On the contrary, the shine angle of LED lamp is 120 degree, so the light could be fully applied. Maybe, 120 degree is considered as deficiency, however, it is enough in many occupation.
T8 of normal fluorescent lamp brand in PHILIPS is 72 lm/W, so 36W fluorescent lamp outlet 2592 ml, but the lamp efficiency is 70%, then the amount of lumen is 1814.4ml. In the opposite, 18W LED fluorescent could achieve 1800ml. Further more lighting efficiency of LED fluorescent increases year by year.
（3）High power efficiency: Every kind of lamp should be powered-up by special power supply except filament lamp. As a result the efficiency of power supply plays a important role in whole lamp.
Take 36W fluorescent lamp brand in PHILIP as a example, the rated power output is 36W, after input ballast the whole power achieves 42.4W. All in all a 36W fluorescent lamp can be replaced by 18W LED tube.
LED tube could save half electricity compared with fluorescent lamp.
（4）Long life-span: LED tube has 50000h life-span. While the high quality fluorescent lamp only has 5000h, which means 10 times gap.
（5）Environmental friendly: No mercury contained in LED tube. 36mm fluorescent lamp has about 25-45mg mercuy, 1 mg mercury could pollute 5454.5 kg water.
（6）Wide arrange color temperature: LED tube could provide random color temperature, which in the other words could achieve any color of lamp.
（7）High color rendering index: color rendering of filament lamp is 95, normal fluorescent lamp is 65-80, while LED tube could achieve over 80.
（8）No ultraviolet rays occur during using of LED tube.
（9）Non-glasswork, hard to break, high impact-resist
（10）Equipped with isolation power, two endings of LED tube don't touch AC electricity, the voltage is only below 36V, no dangerous.
2.Price
The only drawback of LED tube is its price. While, if you consider all the elements which include life-span, energy-saving, better characteristic and non-pollution, you will find the investment on LED tube is worthwhile. Set 50000h as example:
