>>22809878I had a couple of pic related in my backyard. It's a big yard and they don't give off much light (nowhere near what the image shows) but they're good for leading the way if I take the trash out at night.
We didn't have very many fireflies but when I took the lights down, suddenly there were tons of them. Even that tiny bit of light was enough to drive them away. It wasn't that the LEDs were drowning out the light from the fireflies, it was actually driving them away. If you have a light on your back porch or other lights back there, try leaving them off for a week or so and see what happens.
