Precautions for replacement of LED tube lamps in school renovation
High requirements for energy-saving transformation of LED tubes in schools. In order to protect the eyesight of students, first of all, there should be no stroboscopic, so the power parameters of the LED tube should be increased accordingly. The power supply must be constant current. The capacitor filter should be good, and the wave curve should be clean.
How do consumers judge? The simple way is that the light does not flicker.
Secondly, the requirements for brightness are also strict. How do consumers choose?
It is also possible to test with a illuminance meter. Whoever has a higher value is a good thing. The test height is 1 meter high, and now only the brightness can't fool people. The brightness is not high, it is made of small chips, the life will be short, our Benwei18w brightness is 2500lm, the luminous efficiency is 2500/18w=139lm/w, and the cheap tube is only 70-80lm/w, so it will not save energy. Pay a lot of electricity bills
Again, from the perspective of energy saving: the brightness is the same, the brightness of the LED tube can exceed 18w when done with 14w, and it saves 4w, 10,000 tubes, and 40,000 watts, the effect is amazing. Therefore, it is not necessary to use 18wled tubes. For example, Philips 15w can replace 40w fluorescent lamps.
Wide voltage 85-265v, high PF=0.98, high luminous efficiency, all energy-saving indicators.
Most of the low-priced LED tubes have a life span of less than one year, and some have to be replaced after only half a year. Why not buy good quality? It's not much expensive, and the life span is more than 3 years, so why not do it?
Durability: 3 years warranty, only good materials have this effect. No manufacturer will tell you these secrets, and they don’t understand
In short, the most important thing about LED tube selection is cost performance, not just the price.
