Hi,
I didn't know where else to ask so here goes. I'm a pro videographer and would like a portable 120v supply to power a 250-500w modeling light. This is for field work and I'd like it to have 20-30 minutes of juice (at least) between charges. I can put it in a backpack or if small enough a belt pack. My idea is to either use the 12v NiMH battery I own or get another if necessary and connect it to an 400w inverter. I guess I'd need some sort of bridge to convert the 12v DC to AC. My question is: Do you think this is doable and if not why. I'm not an electrician but know a little which is probably worse than none :001_huh:. If not doable please explain why. I suspect the current draws will be large and the battery life is probably the questionable thing here sooo..
Thanks very much for any input....

Look up Larson Electronics. They have one that is supposed to provide power up to 24 hours on a single charge. I have no idea how much this would cost, but I imagine it's not cheap
