I am about to wire my light controller up in a day or two any electricians on this board that can confirm i am buying the right wire its a 240v controller for 8 1k hids. The wire run will only be about 7 feet. I already have the breaker and everything else needed. I just want to make sure I get the right wire and not burn my place down. Any and all help will be greatly appreciated.

You should wire to the max rating of the unit, 50 amps not the proposed load 8000w (33 amps) I would go for 4/2 red wire unless you need a common as well than 4/3. Then if you plug anything else in you are efficient and not heating your wires
 
With that amount of electricity, you should really hire an electrician. Just for the peace of mind.
I dont think saying you asked around, on rollitup, will matter to your insurance company if there is a fire.
I just had a feed to a subpanel hooked up, and my electrician didnt even charge me. Everything was there, he just made the connections, and checked everything out.
Just my 2c

You want 6-3 wire. (6 awg, 3 core & ground)

6-2 wire is required, the ground isnt part of the count. 6-3 includes a neutral, not required for this install. With 6-2 the white wire is tagged on both ends with RED or BLACK electrical tape in order to denote that it's a HOT leg. The ground goes to the little screw on the left. The middle screw on the terminal block is not used.

So you're saying that the center connector between L1 &L2 is not the return?
 
This install requires a 50 AMP double pole breaker. No neutral is used on this feed.

Note that lug is not marked, if it was marked "N" then one would need a neutral. There is no such thing as a return. A neutral is only required for 120 Volt feeds. Ive wired many of these and trust me 6-2 wire, 50 amp breaker. Feel free to post a pic of your wiring on both ends before you power it up.
 
If this helios was one with an integrated timer the middle would be used and marked "N" to provide a 120 volt source for the timer. The models with trigger cords don't require a Neutral.

With our power system a Hot to Neutral is 120 Volts. Hot to Hot on alternate phases is 240 Volts.
 
The #6 wire will be a very snug fit under the loosened lug screw, do not cutoff any of the copper strands, just be patient and finesse it.
