Which gives more light (is brighter): a 1200 lumen bulb or a 20-30 watt bulb?
Looking at outdoor solar spotlights and trying to decide which is brighter.
Lumens are the measurement of brightness. Watts are power or more specifically heat. Pay no attention to your watts if you have lumens to compare with. A regular household bulb is 60w.
