How many watts of led equals 40 watts of fluorescent?
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.

How many watts on led strip lights?
There are many different varieties of LED strip lights, the watts is usually measured per one metre of the LED strip. The most common watts per metre LED strip on the market today is 4.8 watts p/m and 14.4 watts p/m. The total amount of watts for your LED strip would then be worked out by multiplying the wattage p/m by the overall length of your LED strip. The wattage of the LED strip usually determines the brightness of the LED strip. Usually the higher the wattage, the higher the output. Output is measured in lumens.
