Report Abuse. Wattage is what determines the brightness of the light. For example, a 100 watt bulb is brighter than a 60 watt bulb. Lumens is the unit of measurement for that brightness.For example, I believe that a 60 watt bulb gives 1300 Lumens of light.As where 100 watt bulb gives 1450 lumens.or the same wattage, LED light bulb produces much higher lumen than the older type light bulb. Yes, wattage (voltage x current) does matter but only to specific type of light bulb. Ultimately it is the amount of lumen that a light bulb can produce that determine the brightness.
