I thought my 400w halides were expensive to run

I've got one of those on my Nano Cube

Wow!  That's about $10 per hour of bulb life plus electricity to run it.  And each bulb would only last 1 month at 8 hours a day so plan on $28228.68 per year just in bulbs.  Maybe we could get a group buy together and get a better deal. The bulb color looks like a 10k on the graph but its listed as a 6k.
I wonder what those are really used for.

what are those used for?  Super large screen projectors like at stadiums?

I'm not sure what there used for, maybe those big spot lights?
