Okay, so I have pretty limited knowledge of lighting configurations so I need some step by step instructions. I'm making a costume which will require a high power LED, around 10,000 lux, to be attached to a power source with an on/off switch. Let me first say that weight is not a big concern. I haven't picked a light yet, but the size will be a foot across or smaller and as I mentioned, 10,000 lux. The power source, most likely a battery pack(?), must have an on/off switch, OR if I can be instructed on how to configure a separate device which just allows me to switch it on and off, that will work too. So the light will be situated securely above my head and I can keep the battery pack in a backpack, or hopefully, if it's small enough, in my hand. Either way, I need the ability to turn the light on and off with minimal movement, while my hands are down at my sides. So with this information in mind, I want to know how to connect the light to the battery pack. I have soldered before, so if that's what I do then I need to know what wires to solder. If my light has a cord with a plug, do I open it up to solder it and how do I open That's most likely the type of light I would get. And furthermore, how many volts do I need in the battery pack for a 10,000 lux LED? And where should I get such a battery pack, hopefully one that has an on/off switch? And lastly, if this battery pack is substantial in size and I can't keep it in my hand, how do I configure a handheld on/off switch. Any advice is appreciated!
