How much wattage do these lamps use?

Hi, I wonder what these old school floodlamps use in power? They are part of a charity organizations land who don't seem to be concerned that they're left on all day/night.
I'm guessing they're at least 15 years old.
Thanks

Typically 500watt , but could be more or less , basic led replacement tubes are available if they use them , some use the old son lamps which are more economical .

From the housing they're some sort of discharge lamp, the (orange) colour says SON, probably more like 250W each, possibly as little as 70W each.
Beware of LED replacements- there are lots about but the cheap ones splurge light everywhere (those probably throw 100 degrees or so, cheap LEDs are more like 180 degrees) and the colour rendering is very different.

It's true, the light they project is very orange. Thank you

So likely only 70 watt, could be more, but these lamps last less time when switched off and on, I would still switch off in the day however.
