Currently, the 48-inch led fluorescent lamp tube 18w is used for how much dc voltage
The voltage in each company is different, and you have to ask the manufacturer.It's usually made of 2835 chips, about 60mA, or about 3.3 volts.
The other 48 inch is 1.5 m lamp tube, the lamp tube of 1.5 m should also do 20W above. The average of 1.2 m is 18W.
There is very little dc voltage input on the market, and there is also a built-in external drive. Most of them are built in, with 220V input.
