Why not ask the race organisers / competitors?
They will presumably be more au-fait with the regs (if there are any) than you, or will have a good idea who you should ask.

What's the purpose of the lighting?
Is it just for the drivers to see where they go and the audience to see the crashes, or is it for filmcameras?
To give you some references:
- Sunlight on an average day ranges from 32,000 to 100,000 lux
- TV studios are nowadays lit at about 1,000 lux (in the eighties it was 3000 lux, but the cameras are better now)
- a bright office has about 400 lux
- moonlight represents about 1 lux
- starlight measures a mere 0.00005 lux
So if you're having TV there for the event you need more than 1000 lux, make it 2000 to compensate for unevenness.
Handheld hobby cameras need more light than professional ones to get a good Picture.
But if it's just for people to see the event you don't need more than an average office.

I say this as a resident of Florida, which is world renowned for light pollution, choose fixtures which do not allow the light to go up, and choose wavelengths of light that do not easily reflect back up (ie, no orange)
I don't know if there is anyone here that is an expert in Street Lights for installation, let me ask ( I work at a very large power company, but there is a process in place for asking permission to ask permission to ask about processes to ask permission : ) )

One quibble. For minimizing the damage caused by light pollution by making it easy to filter out without removing much of the light from what you're trying to view/image you want lights that only emit narrow spectrum light like mercury vapor or low pressure sodium vapor lights. The latter produces light that is a ghastly shade of orange.
I'll add that fully shielded fixtures instead of ones that are only mostly shielded is very important to minimize skyglow. Light that's emitted at upward angle of only 1 or 2 degrees is much more likely to be reflected down as skyglow before escaping the atmosphere than light that goes almost strait up. This is especially important if you use LED based lights to save on operating costs since the phosphors they use result in a broad spectrum output.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I was actually planning to point them straight up and bounce the light off the Moon, relying on the reflected light to illuminate the race track. After all, we're the power company; why would we want them to conserve power?

Kind of funny, no? That we spend so much effort to advertise customers to use less power when you would think it would be the opposite? (Obviously, I know why, just a funny observation)
|
|
|
|
|
Yes, it is a bit odd to be telling people to conserve, when my paycheck is tied to how much they use. I really must consider not doing that anymore.

I work for a water company that obviously does the same.
When I started working there we had some nice fountains outside the offices, they've been turned off for a few years now because it gave off the appearance of wastefulness (although we have so much water we sell it to other water companies when they run out).
Some men are born mediocre, some men achieve mediocrity, and some men have mediocrity thrust upon them.

Come on out to Wild Horse Pass and see what they use...
(Not this week; I'll be up at Monument Valley.)

Where the heck is Wild Horse Pass? I've seen the ads for years, but there's never been any mention of how to find the place. Ak Chin is in Maricopa, Bucky's is in Prescott, del Sol is in Tucson; where is Wild Horse?

Can't you look at what other race tracks have done?

Certainly. If we had one. But this is the middle of the Mojave Desert, and we don't have a lot of NASCAR tracks handy.

I just came across this new york based cloud hosting provider targeting just developers, they were in the startup news because they have raised 30+ million in funding.
https://www.digitalocean.com/[^]
The plans are crazy cheap. I haven't tried it. So if anyone looking for a cheaper hosting option and willing to give it a try, please share your experience.
There is even a $50 credit for writing a tutorial[^].

I have just seen someone pushing their hosting over on the bitcoin forums to use them for cloud mining......wasn't you was it? 
|
|
|
|

Very cool. I just signed up - Heroku is great if you want free, but it's nice to explore other "almost free" options as well.
Thanks for the post!

Hey Marc,
What OS do their VMs come in? Thanks.

Various flavors of Linux and one of Ubuntu 12.10, I think.

Thanks Marc.
That probably explains the relatively cheaper costs. Most VPS hosting providers offer Windows Server 2012.

Thanks for heads up. 
It was broke, so I fixed it.

I have been trying them out for a few weeks now. So far so good. I have a VPS elsewhere just for my own hobby and may switch to digital ocean after I get everything setup with one domain the way I like it. Biggest problem I have had is configuring a mail server. LAMP config is easy. The really cool part is before I start a big install of something I make a snapshot so that if I screw things up I can get back to before the screw up. You can also install a desktop and VNC and use TightVNC to see an actual desktop. I didn't like the desktop real well it hogged resources bad. (I'm on the 1G of memory $10/US plan).
