How many W LED spotlights can be as bright as regular 35W spotlights?
3*2W is a high power LED lamp brightness, high power 2W lamp is generally in about 150 lumens. A total of three, which adds up to more than 400 lumens.
LED lamp is a DC voltage of 2.5V and 5V that the original lamp transformer voltage should be AC 12V. If you want it to the transformer rectifier DC power supply, you see that in the operating voltage of the LED lamp is much in buck, Buck buck by resistance.
2W's LED light, which is a high brightness lamp, but I don't know what its working voltage is.
