# How Bright is 100 watt LED Flood Light?

To answer this question we need to know the following: How is light measured? And how much light do we need in our area? Answering the first question lights come with power (wattage) and according that they will have a different amount of lumens Hyperlite LED Flood Lights come with 120 lumens per watt, that means that a 100 light has 12000 lumens per watt.

Normally to measure the light on some surface is measure with lumens and foot candles that is why lighting it is all about lumens. But what are lumens, exactly? And how do we understand what lumens are in light bulbs and Hyperlite LED Flood Lights fixtures?  Lumens are now the way to find out how bright a lighted bulb or integrated Hyperlite LED Flood Lights lighting fixture is.

And if you want a fixture with bright, luminous personality, it is the key to choosing the perfect piece for your lighting scheme. We talk about foot candles so What is a foot candle? We will explain what is a foot candle with a formula to understand on a clearly way: 1 lumen / square foot = 1 foot candle, the lumens is emitted by the light and the foot candle is what the surface will receive according the distance and lumens emitted.

In simple terms, lumens (its symbol is lm) are a measure of the total amount of visible light (for our “human” eye) from a lamp or light source. The higher the lumen rating the “brighter” the lamp will appear.

Now it is time to answer the second question:
The general information (testing by many people being part of the rule of thumb) for providing light for an area is a minimum of 30 watts per square foot or 50 watts per square foot is optimal. You can determine the proper lighting for your area by using this formula: 30 watts x square feet. Example: You have an area of 10 square feet - 30 watts x 10 square feet = 300 watts / square feet minimum or 50 watts x 10 square feet = 500 watts / square feet.

If you want to have lights on an outdoor area we highly recommend to use Hyperlite LED Flood Lights because they are really bright, they are water and dust proof and come in different bracket presentations (you can only choose 1 bracket) so they will fit on your lighting project.
