Let There Be Lights

[Dan Wesson]

Curious. They say the LED lights are brighter, but don't discuss dispersion or total area coverage. In my experience, LEDs make intense but focused light. Easy to beam, but not distribute evenly and consistently.

That would explain why they need to be so close together...and why it still seems dark. These things aren't scattering the light like the old ones did.

So true. Plus they make heat and the flat finned tops make perfect sites for nest and bird droppings.

Lot's of them used up here at sites around the area. The electricians have noted they apparently don't live up to the hype about their supposed longevity. We'll see.

Got's to be better than nothing....

Funny you should mention bird nests. They installed new led lights at our 8 tennis courts last spring. Birds are nesting on 3 poles so we've had to move the benches and they've already been back twice to try to adjust the lights as the dispersion makes the light bright behind the fences and very hit and miss on the courts.

LEDs generate almost no heat. That's why they are so efficient.

They do generate some heat, though not nearly as much as a sodium or mercury bulb.

The LED street lights are arguably brighter, but the resulting light is more focused. I think the light is less useful [[you have bright spots and then dim spots, which makes it harder to see clearly as you walk down the street), but it's a complicated issue and at least we're making progress.

Gannon's points about the LED lifespan being overstated is fairly correct. A lot of the problems with LED lifespan is related to heat. Altho I think that there is no real conspiracy to be found in the conical pieces on top of the lights -- they're a standard interchangeable light sensor [[photocell), so that the street lights turn on at night and off in the morning.
