To ensure LED tube quality, materials are important

　　LED tube on the market today is basically divided into two sections: Semi-plastic half-tubes and plastic tubes.

　　1, plastic LED tube: Early LED Tube Light is used in plastic, because the main use of non-isolated power supply, in order to avoid electric shock problems, so it prefers to use plastic tubes. The biggest problem for this fluorescent is the heat problem, because all the heat sealed in a tube and cannot spread it out, the light fades are very serious, which is not recommended to use. Price is about 2-3 USD / kit.

　　2, semi-plastic and semi-aluminum LED tube: now on the market are selling LED Tube Light basically half of pc half of the PC alloy. Of course, the power is on the tubes inside, so, LED's heat plus the power of the heat is quite large, because usually the lamp power is about 20W. It mainly confirmed the thickness of aluminum; at least the cooling effect is over than 1.0MM, so called standard. I confirm that some samples of the plant, the basic thickness is 0.6-0.8MM and color is aluminum, which proved containing impurities, such generally 5-7 Yuan / sets, quality has assurance, usually around $ 13 / set. Price difference 5 USD / sets.
