Hi,
I'm interested in doing an outdoor photoshoot, but ive never attempted this before. So im trying to plan and get things right before hands.

Can anyone guide me through please:

How do I power my lighting equipment whilst shooting outdoors? I also have a 800w continious lighting (redhead) would my car battery be able to handle the wattage or would this be a recipe of disaster?

cheers.

I use the Alien Bee Power Inverter with a battery to power a strobe or strobes. A gold or silver reflector still comes in handy too when the circumstances allow for them.

cheers everyone.

Artform: of course refelectors are alway the best. one cant live without them.

DCC: i had a look at the link u recommended but they have heavey duty big generators. i was looking for something more in budget.

tat: the Power Invertor seems the sort of thing i was perhaps looking for. so basically, i plug the invertor into the battery and that would in effect create enough electricity to light the strob etc, right? is that the kinda stuff most photographer use as a portable electricity generator in general?

I would only power strobes with an inverter. Don't even use the modeling light or you will kill the battery real fast. And I have herd you could damage your strobe with a inverter that does not put out a pure sine wave. Most do not so be careful..

A PURE sine wave is not a hard and fast requirement, though the crest of the waveform should most definitely resemble more of a sine than a square.

Your car battery is designed ONLY for a high-load short duration power supply and will be toasted very quickly if you power your strobes with it, even faster with your 800 watt continuous light. Even a deep cycle battery (which is designed for long-term continuous output) won't last long because of the load.

Use the right tool for the job (a battery/inverter kit designed for lights) or do some serious research before you put something together that will ghost your lights.

Not to argue but I lived in a house where the main power was a small bank of car batteries (2 of them) and it lasted pretty darned well. We'd get 4+ hours of TV+lights for the hose off of that setup (using the same inverter pictured actually.

hmm

ok so using an inverter is not a good idea to power ur lighting equipment. so what is the right power supply tool? What do pros photogarohers like you use when doing an out door shoot at a reasonable cost.

There is no such thing as location power at a reasonable cost.

Probably your best bet would be the Tronix Explorer at about $350 w/50 shipping worldwide... You can plug whatever you want into it without any problems, personally I think it's much better than the Vagabond pack.

Next option would be to rent a generator, there's one made by Honda that seems to be the preferred unit. I think it may have a voltage regulator built into it. You could also buy your own I guess for other uses I don't know how much it costs.

You can also use small hot shoe type flashes using techniques like you would find here at the Strobist blog.
