Ryan,

Try running them under oil.  This will extend your
duty cycle considerably.  A single .50 caliber ammo
can (available at any Army surplus store, junk shop,
pawn shop, flea market, etc.) will hold all four MOTs.
 Cover them with transformer oil, farm tractor
hydraulic fluid, or ordinary motor oil.  My twin MOT
ballast has the MOT primaries drawing about 20A. 
Without the oil, they got hot as branding irons. In a
steel ammo can with 3 quarts of motor oil, they barely
warm the container in a whole evening of photography
runs at 4400VA.

Cheers,

Greg
