3 Facts You Always Ignore About Watts and Lumens for LEDs

By Luna on 04/17/2017


Enjoy the charming glow of an incandescent bulb while can’t stand its high expenditures is a dilemma most of us are facing. Switching to LEDs seems to be a perfect solution to the problem. Before choosing an LED fixture, we should always take Watts and Lumens into consideration as they are the two basic aspects of light output aka the result of the light it will produce. The article is going to explain the two concepts as well as their relationship for you.


FACT 1: Lumens have nothing to do with Watts


Many of us misunderstood that the higher the wattage of a bulb, the greater the lumens is. However, the fact is that there is no direct connection between watts and lumens. Watts refer to the units of power used by a bulb whereas lumens are units of light output emitted by the bulb. Normally an LED bulb with higher watts always gives off more lumens as the picture shows below:




However, two LED bulbs with the same wattage never mean they are the same in light outputs. How much light output a bulb will emit depends on how efficient the bulb is. Specifically, an LED bulb with lower watts but really gives off a large amount of lumens proves that the bulb is rather efficient than one that operate at the same amount of wattage but gives a lower lumens. Generally speaking, a 60W incandescent bulb usually gives off 800 lumens, while LED bulbs always use far less power than incandescent and halogen bulbs.


FACT 2: Put Watts aside, let us talk about lumens


In the past, people used to consider more about the wattage of a light bulb as the amount of power must be kept within the maximum capacity of a circuit. Otherwise there will be potential safety hazards. Now wattage becomes less important with the reduced energy consumption of LEDs. As a result, people nowadays pay lots of attention to lumens (i.e. the amount of light) before their purchases.


FACT 3: Your house is able to be much brighter


Can you imagine that you are able to use a 100W equivalent LED bulb in a 60W LED fixture? This is because that your LED is as bright as a 100-watt incandescent bulb while using probably only 10 watts. In other words, the maximum power of your lighting fixture is 60 watts but you only use 1/6 of that. Thus you are allowed to choose an LED with much more wattages as well as lumens (brightness).


Sometimes switching into LEDs with higher lumens means costs saving as you may able to reduce number of lighting fixtures in each room. That is to say, one fixture illuminates wider areas helps eliminate extra fixtures.
