How to choose factory lights to '0' maintenance cost?

When many companies choose lighting fixtures in their factory workshops, they are reported by the workshop supervisor and the procurement department implements the procurement. However, due to the lack of lighting technology-related personnel, the companies often have no ideas when purchasing lamps and are fooled by some lighting suppliers. I bought a cheap lamp, or the price is not cheap, but after actual use, the brightness of the lamp will be weakened or damaged, or the lamp will not be bright. Invisibly increases the cost to the enterprise. In fact, these costs do not need to be increased. Let me share below that as long as these two points are achieved, the maintenance cost of lighting fixtures on the factory floor can be '0'. The first point is that the lamp warranty period is more than 5 years. This is one of the most critical factors for manufacturers. Because as long as the lighting manufacturers dare to promise a '5-year' warranty, then it can be said that the quality of this factory lamp is reassuring. If a lamp seller or manufacturer only dares to promise a one-year warranty, then I believe everyone should be able to imagine the quality level of this lamp. The second point is that the lamp life is more than 60,000 hours. This is one of the most critical factors for the product itself. Because as a factory lamp itself, if it does not have a long service life, even if the manufacturer promises a 5-year warranty, it is useless, because the lighting lamp cannot be used for only 5 years. As the leader of the company, it is all I hope to be able to use it for a longer period of time. The factory lighting products produced by the lighting factory have the above two key factors at the same time. The lighting factory is the first to promise all users a 5-year warranty in China. The life of the factory's lighting is 60,000 hours. If it is illuminated for 10 hours a day, it can be used for more than 10 years without breaking!
