What size (va) step down transformer (277 volt to 120 volt) to power a 799.7 watt/7.27 amp load? 1000 va?
 
an 800 watt, 8 amp what ???
Power-factor and in-rush current associated with your load will have an effect but a 1 kva would normally be fine.
 
dropping 277 to 120 volt with a step down transformer the load I am applying is 8amps

I am pretty sure my transformer should be a 1000 va transformer. Just checking.

Many LED fixture manufacturers also have driver units for their product that uses power electronics in conversion and take into account the effects of the load. Moving past that point, what's the input voltage of the LEDs?
