.... a 5000watt bulb would take a 41-45 amp service to run @ 110-120V... or 20-22 amps @ 220-240V

PS. Your 'average' modern home today gets 200 amps @ 220-240V, while an older home may only have 40-60amp service... and your again 'average' household wall socket can only provde 15 amps @ 110-120V

In other words... a 5K watt bulb is going to use a metric f***ton of power

i can;t imagine this is effencient for growing at all
