What are 100 Watt LED Flood Lights?
100 Watt LED flood lights are designed to replace 250 Watt to 400 Watt Metal Halide and High Pressure Sodium Flood Lights. Depending on the efficacy, they can product between 13000 lumens (at 130 lumens/watt) and 18,000 lumens (at 180 lumens/watt). The reason there is such variability in lumens for a 100 Watt LED Flood Light is because flood lights use different LED chip sets. The only thing consistent between all these various options is they all consume 100 Watts of power. How they convert the power into light is all based on how efficient the chips are. So keep reading, and we will explain in greater detail that you should always choose a LED fixture based on lumens, not watts.
How many (LED) Watts to replace a 250 Watt Metal Halide Flood Light?
The much better question you should ask is: how many lumens do I need to replace 250 Watts Metal Halide Flood Light? We answer that question next.
Generally speaking, it takes around 10,000 lumens to 15,000 lumens to replace a 250 Watt Metal Halide Flood Light. To calculate the efficiency or efficacy of the LED light, divide the lumens produced by the LED fixture by the efficacy and that will give you the appropriate watts. Don't be surprised if this ranges greatly. Higher efficacy LED flood lights cost a bit more, but consume less energy. And that's what saves you MORE MONEY with even lower lighting bills.
For example, lets choose a LED Flood light fixture that produces 15000 lumens. Then try to find the most efficient LED flood light. Here are two examples
At 100 lumens/watt, you will need 150 LED Watts to replace 250 Watts Metal Halide. (100 X 150 = 15,000)
At 150 lumens/watt, you will need 100 LED Watts to replace 250 Watts Metal Halide. (150 X 100 = 15,000)
How many (LED) Lumens to replace a 250 Watt Metal Halide Flood Light?
Through experience and years of selling LED lighting, a fixture producing 10,000 to 15,000 lumens seems to be a good range. The range of lumens is large because there is no one light that is the best solution for all applications. So, how can you determine the perfect flood light for you?
A lighting plan! A lighting plan allows you to model or simulate an outdoor space and install different 100 Watt (or other LED Wattage). The plan will "find" the right light. At the end, the plan shows you light locations, foot candle readings and how balanced the light is across the entire space. The Lighting Plan is the guide to finding the right replacement.
And the good news. We do lighting plans for free for our commercial and industrial customers who want to convert over from Metal Halide, HID, High Pressure Sodium and fluorescent lighting. Just scroll to the top of the page and ask for yours.
