When compared with fluorescent lighting, LED downlights consume around half the energy, with a 12-watt LED downlight capable of providing the same brightness (or lumens) as a 24-watt fluorescent bulb. Lumens are now used as a more accurate measurement of brightness, and watts to gauge energy consumption. Modern LED downlights are designed to use less energy and therefore have lower wattages, making them much more energy-efficient while providing more light output.

Since wattage measures energy consumption, traditionally, bulbs with a higher wattage would produce brighter light than low wattage bulbs but, with modern LED lighting, this is no longer the case.

While most people still associate wattage with the amount of light you expect to get from a bulb, watts are actually a measurement of how much power goes into the bulb, not how bright it is.
