How much energy do LEDs save compared to traditional flood lights?

When you swap out old-school halogen or high-intensity discharge (HID) fixtures for modern LEDs, the drop in your energy bill is immediate and substantial. On average, solid-state LED fixtures pull about 80% less electricity than halogen bulbs while delivering the exact same amount of brightness, if not more.

To put that into perspective, think about the actual work the bulb is doing. A traditional halogen flood light is incredibly inefficient because it relies on a burning filament. Roughly 90% of the energy it draws is wasted as pure heat, leaving only 10% to actually light up your yard or parking lot. LEDs run on an entirely different principle, converting almost all that electricity straight into usable light. Because of this efficiency, they manage to crank out four to five times more lumens for every single watt they pull from the grid.

Let's look at a real-world scenario. If you have a commercial property running a couple of old 500-watt halogen floodlights for security, you're burning through 1.000 watts every single hour they're turned on. You can replace those with two 100-watt LED fixtures and get the exact same level of illumination, cutting your power consumption by 800 watts per hour. If those lights run all night, every night, that adds up to massive savings over the course of a year. When you factor in those lower utility bills alongside the fact that you won't be climbing ladders to replace burned-out bulbs every few months, the return on investment for upgrading to LEDs is a no-brainer for both homeowners and businesses.
