General T8 lamp because the lamp above the space is large enough, the constant current source can be mounted inside the tube. Therefore, during installation, the rectifier can be original bracket, do not remove the starter directly to the lamp can install up. T5, T4LED because fluorescent lamp is small, does not fit the current source, current source can only be mounted in the holder, so manufacturers generally do T4 \ T5, it will configure the bracket, the bracket is equipped with a constant current source, Further, when the directional tube installation. Direction is reversed, the lamp does not light. We are considering adding some conversion circuit, so even in the case of lamps installed backwards, the lamp can also work. 2, voltage: Geri photovoltaic production fluorescent although there are wide voltage adaptability, AC 85V-- AC 245V, can work normally. But the long-term voltage is too high or too low, it will affect the power factor constant current source, that caused a slight impact on the energy saving effect. This will also affect the life of a constant current source. Therefore, the general should choose the appropriate voltage fluorescent tubes. Such as: where electricity is 110V, you should use our specially designed 110 mains fluorescent tubes. 3. Cooling: Geri photovoltaic production fluorescent material with an aluminum heat sink casing, under normal circumstances, the heat is not a problem. However, if used where heavy dust, dust should be regularly to prevent dust covering the radiator, the impact of heat. 4. Waterproof: LED fluorescent lamp is made from top to bottom because of two parts: the upper part of the aluminum radiator, lower part of the diffuser, there is a gap at the junction, therefore, to prevent fumes, water vapor to enter. If you use gas, vapor heavier place, suggested adding a protective cover. General protective cover on it. 5, shock: LED lamp has a strong anti-vibration capability. As long as the violent impact, usually does not cause damage. But may have some impact soft board. The traditional fluorescent, glass, and inside near vacuum, vibration could cause an explosion, with particular attention to vibration. Please call: 13715281508 18102283661 Zhao Health QQ: 1981450034
