I searched for topics similar to this and could not find an answer:

 

I'm looking at potentially working with the Arri Studio T12 tungsten light, with the unit voltage range of 230V. I'll be working on a stage with 5 wire 3 phase power. How would I power it from the wall (300 amp cam-lok) for what I believe would pull 208v? Let's say if this scenario is correct, it has a 208v lamp. Would I just need a 100 amp 250v snakebite? If this is the correct approach, is the power relatively evenly pulled from the two legs? I would also have have threefers at the original connections so I could power a distro for other lights.

 

T12 specs: http://www.arri.com/...o_t/studio_t12/

 

Please let me know if these are the correct numbers and correct approach, or if I should be looking at another way of doing it on the stage's power. While we're at it, what would the approach be like for powering a 20k Mole Solarspot on a stage with this setup?

Thank you in advance.

Although the spec on the Arri sheet indicates 230v, I believe here in the USA they run a 120v lamp.

Out here the T12 comes with a 120v lamp and has a 100amp 120v bates connector on it.

 

This becomes a problem if they are going to be on for more than 3 hours.

 

12k/120v= 100amps.  Longer than 3 hours and you'll toast the bates.  the 3 hour rule also dictates that the cable/connector is now only rated at 80%.
