Poor heat of the LED is well known, will inevitably bring the wick life. The design of the existing LED lights tend to heat difficult to meet the requirements in the field of a heat dissipation is very demanding, but with very poor passive cooling, and is air-cooled, or even a closed air- cooled. As some lamps with plastic sleeve between the driver board and the aluminum heat sink to increase the reliability of insulation, irrigation cooling silicone to increase the cooling capacity. T8 lamp is closed, the wick can only rely on air convection heat transfer to the lamp on the back of the aluminum tubes for cooling. General, the internal temperature of these lamps will have seventy to eighty degrees. And if we take into account the heat, weight problems; take into account the weight, heat dissipation is difficult to guarantee, this dilemma of choice in the existing design, there is no feasible standard.

    LED driver board may be a life of only five years (home) temperature of 70 degrees, far from reaching 10 years of LED wick concept. So much more cost effective compared to the same brightness of the fluorescent, even if the fluorescent only 1 year of life, 1W1 fluorescent is much more than 1W10 $ led tube light  . Damage to the LED lamps are often the wick is not bad, have the entire lamp replacement. Calculate the tenth driver board have to discard the remaining nine tenths of the lamp (wick and the heat sink accounted for most of the cost of the entire lamp), if each vendor did not do a good job recycling customers do not like the product.

    LED wick life was index decreased; electrolytic capacitor temperature is increased by ten degrees lower life expectancy in half; the MOS temperature, resistance increases, loss increases, the temperature will rise (constant current mode) with increasing temperature, and ultimately burned . Of course, the domestic manufacturers did not give a specific LED lamp life, and propaganda of the time just mentioned LED wick life of 100,000 hours LED life of bottlenecks in the system driver board t8 led tube wick is not damaged, the system drive has hung up.
