The Distinction Between Lumens and Watts

Nowadays

The advent of energy-efficient technology like LEDs has rendered power consumption irrelevant when assessing light brightness. Consequently, rather of acquiring bulbs based on wattage, which just quantifies power consumption, users are now provided with lumens as a measurement.

Difference

In conventional incandescent light sources, greater wattage often correlates with increased brightness. In the case of LEDs, the situation differs as there is no established standard for correlating watts with output. Lumens is a quantification of total light emission, indicating the bulb's brightness. A greater lumen count results in increased brightness of the light. Consider it analogous to the relationship between gallons and milk.

Chart to translation

The Federal Trade Commission mandates that all bulb manufacturers display the lumen count on their labels. They furthermore encompass the life expectancy and the projected annual energy expenditure. With the introduction of more energy-efficient lights, there is a noticeable shift from wattage to lumens. The following chart translates watts into lumens to facilitate the replacement of incandescent lights with LEDs, based only on estimates for incandescent bulbs.

150 Watts equates to 2600 Lumens.

100 Watts is equivalent to 1600 Lumens.

75 Watts equates to 1100 Lumens.

60 watts equate to 800 lumens.

40 watts equates to 450 lumens.

25 Watts equates to 200 Lumens.

Tip

Numerous residential and business fixtures were not built for LED lighting. They generally have warnings like "Fixture designed for a maximum wattage bulb of XXX". These heat ratings are designed to deter users from inserting a bulb with a wattage exceeding the fixture's specifications. LED lights, due to their significantly lower power use, generate reduced heat. Consequently, a 60-watt equivalent LED bulb may be utilized safely in a fixture designed for a 40-watt incandescent bulb.
