How to replace the 40w fluorescent tube?
This depends on the luminous efficiency of your LED tube. For example, if your tube is 80LM/W and the fluorescent tube is 60LM/W. The luminous flux of 18W LED=18*80=1440LM, 18W daily tube luminous flux=1080. If the luminous flux of fluorescent lamp 1080 is converted into LED, then 1080/80=13.5W, energy saving 4.5W. The above are just examples I gave. The key depends on the luminous efficiency of the LED you bought, and then you can calculate it with the formula I gave. The host should pay careful attention to the light effect, this is very important. I am a researcher and developer of LED lamps. Don't be misled by the general numbers that those people say, it's best to do the calculations yourself.
The led tube bracket is universal, remove the starter and ballast. One end is zero wire, and the other end is live wire. Lights up when power is on.
