Light bulb 20w, can you use a to2 ballast 40w
The capacitor in the regenerator short-circuit - - - a new one A 40W rectifier with two 20W tubes is theoretically possible.
The 40W ballast can be used in a 30W light tube, but it will shorten the life of the tube (because the voltage on the 30W lamp is slightly higher). The electronic ballast is the high frequency trigger light pipe and automatically maintains constant current power supply, which is suitable for wide range (30W ~ 55W). Electronic ballast 55W and light pipe 40W application, not easy to burn, electricity power 40W (electronic ballast loss Two red wires connected to the power source, two black wires on the left and one side of the lamp at the end of the lamp, and two black wires on the right side of the diagram on the other end of the lamp.
Direct parallel is ok, the hardware store sells 1 to 2. You don't have to do the wiring, 20W will be bright and bright in 30W. When the 30W is installed in 20W, it will be unexpectedly bright and brighter than the usual lights. But its lifespan is greatly discounted, and it may burn at once
