10.13.2017 Most of the poles are up, many are already assembled. A quick shot from the freeway. I would guess they will all be up in a month.

Those things go up like weeds. Should be enjoyable relaxing at Cottonwood with the nearby 2,000 lumen, I mean candela, red LEDs flashing every few seconds and the whoosh whoosh providing audio.

The R&R tracks at night when cooling down pop and crackle. But the Turbines also have the same noise. But there's was another noise I heard it sounded like the transformers were unloading there was a "Thumping" like sound periodically.

I thought to myself, how does tommy750 know they are 2,000 lumens?? Well, it turns out the FAA measures aviation obstruction lights in candela, not lumen. Candela is more important as that defines (loosely) how far the light can be seen from whereas lumen defines how much can be seen with the light.

A laser pointer for example vs a big fat flashlight.

Minimal research suggests the FFA requirements are 2,000 candelas, visibility from about 1.2 miles away at night. There is more math and science behind the wind turbine obstructing lighting systems so do some research if that interests you.


Tom and I were there a month or so ago and I got stuck behind a caravan of turbine blade delivery trucks. Kinda sucked since I was on the new and improved McCain Valley dirt road freeway they created, it's practically paved all the way to Cottonwood.

About a month ago they left some of their junk at Buckman Springs.

I would guess the lighting would be the same for Power poles and such. Never thought about the lighting requirements per FAA. Good info.

Technically I think the requirement is 32.5 candela once the obstruction reaches 200 feet but many of the lighting systems I researched had specs of 2,000 candela and some FAA docs had charts showing as much as 20,000 candela for some situations. I am no expert at all, just did some searching and learned a few new things.

Well, heres a FAA doc on lighting requirements.

Well Daren, didn't know you were so fascinated by lighting units! I corrected my post to say 2,000 cd so we're good smile

Think I'll get a shirt made that says "I'd rather be sitting in a Sling-Light"
