You are watching: How many lumens in 150 watt bulb
There have actually been some major changes in light in current years due to the advent of energy efficient CFL and also LED bulbs. Familiar old incandescent bulbs are ending up being a thing of the past, as both your energy-hogging habits and their “wattage” rating come to be obsolete. In their locations will be high effectiveness bulbs with a much an ext accurate “lumens” rating. Here’s a handy guide to aid you understand the difference and also navigate the changes.
Watts vs. Lumens
To begin with, what’s the difference between a watt and also a lumen?
Watts room a measure up of exactly how much electrical energy something uses. It actually has nothing to perform with just how bright a bulb is, but incandescent bulbs room so comparable that once we to buy a 100-watt incandescent irradiate bulb, we had actually a basic idea of exactly how bright it would certainly be.
With newer types of bulbs, the takes far fewer watt to produce just as much light, so wattage ratings are no longer very useful. Each kind of bulb is different, and the whole idea is to develop bulbs that use fewer watts to make more light.
Lumens, on the other hand, in reality measure the lot of irradiate being put out through the bulb. Lumens room a much more accurate measurement, due to the fact that it tells you exactly how the light in reality performs, nevertheless of the resource that created it.
One lumen is about equal to the amount of light put out by one date of birth candle that’s one foot away from you. To assist you get an idea the the lumen scale, a standard 60-watt bulb puts out roughly 750-850 lumens the light. If you’re selecting bulbs for task lighting, look for bulbs with 1000 lumens or more.
Lumens per Watt Rating
Like miles-per-gallon in a car, the lumens-per-watt rating measures how much light that specific bulb produces per watt of strength used, which speak you how energy effective it is. Under the new system, when shopping for a irradiate bulb, girlfriend should first look because that the bulbs that create the number of lumens you need.

Once you understand the best brightness, you have the right to then look at the lumens-per-watt rating to discover the pear that’s most power efficient. The lumens-per-watt rating is one average, since light bulbs come to be less reliable as lock age.
Energy Star Bulbs
If you’re not into fine print, one easy means to choose light bulbs is come look because that the power Star rating. To qualified for power Star, light bulbs have to meet details lumens-per-watt standards. Here’s a handy chart to aid you understand just how watts and also lumens relate come each other under the power Star system:
