Hey folks -
I'm just getting into amatuer filmmaking. I took a class on low budget
lighting and we spent a great deal of time talking about scouting
locations properly for lighting. Two things you really have to worry
about are power draw and heat. With movie lighting, it's easy to blow
the circuits because several 1000 watt bulbs draw a lot of power, and
then also they create a lot of heat. This makes it easy for them to
melt plastic filters, their housing, even blow up the bulbs themselves.
That's why you hear the director call "Lights! Camera! Action!" --
because the lights are shutdown between takes to cool off.
Of course, most of these problems are caused by the fact that these are
incandescent bulbs, which waste a lot of energy as heat. A lot of these
problems could be sovled by more effecient lighting techniques -- say
LED bulbs.
I know that LED bulbs are just now getting into home lighting, but I
wonder why they aren't used in more film lighting. Film lights are
expensive anyway, so I would guess LED lights could compete more
effectively than in the home.
Why are LEDs so small?
Is it possible to get an LED bulb that kicks out 1000 watts of light,
yet leave a small current and heat footprint?
