Hello, I bought a LED lamp, it says 4W on the package. I wonder how much power it can actually draw. Many guides on LED lighting say that it pays to install only where they shine a lot. And hence my question, is there a catch in these small 4W, or, for example, as in fluorescent lamps, they consume little, but only after warming up, and so they consume more than a standard bulb? Do LEDs have something similar, which makes them effective only when they are lit for a longer period, or do they just keep consuming 4W after being turned on?
