>>3462334Enough as in whatever bulb fitting you have, get a tetrahedral-shaped multiplier/adapter to 3 per light stand, don't worry about power draw, these are LED based so any fitting worth its salt shouldn't have a problem. You would were they conventional filament bulbs.
These are lights, not floodlamps, and made for passive soft lighting, not intense flashes. Which ia why I'm recommending using more than 1 per light stand. You can also individually them off/different colours so you could theoretically have a 2/3 orange glow and 1/3 white/blue per stand or whatever.
Put an additional diffuser screen in front of the reflector umbrella to scatter the light, and you should have a pretty kickass setup.
>ignore shittiness of drawing, but it gets my point across.
