The brightness of light bulbs is measured by lumens. Higher lumens means brighter light and lower lumens dimmer light. Many of us are used to thinking in terms of watts. When we want brighter light we get higher watt bulb. That was in the past. Watts will no longer determine light brightness.
The growing popularity of vintage bulbs comes with a trade-off that some consumers may not be aware of, leaving them in the dark in a literal sense. While a 60-watt vintage bulb may share the same wattage rating as a traditional incandescent bulb, it typically emits only around 400 lumens, half the light output of its conventional counterpart, which emits around 800 lumens.
