200WS ( watt second ) lights depending on how you use them ( bare bulb, straight up! )
can put off a fair amount of light ... not TONS ...
i have lumedyne lights and its bulb is a 200WS bulb
bare + straight up they say can light a 8' x8'x8' room

it's not enough to light up a stadium, but enough for portraits and product work, and fill light &c ...

have fun with your new lights !
