Shoot the transformer output 12 v 20 to 50 w lamp is LED12V 4 w can use excuse me?
The big horse car, certainly can carry, isn't it. And is not a small cart. Besides using 4 w is not in order to save electricity The heart bold use. No problem!
Ok, now are LED lamp to replace the original quartz bulb,Can be used, but there must have a circuit inductance/curtains on tube/semiconductor current limiting device (using single-chip microcomputer control)!!!!!
The power of the LED lamp is using a constant current power supply, and shoot the lamp to use 12 v constant voltage power supply, the nature of the power supply is not the same, if used on the LED constant voltage power supply, will directly cause damage to the LED current is too large. Therefore, shoot the light output 12 v transformer 20 to 50 w can't be used for LED lamp.
