This very well may have been my friends, as we usually extend our sessions after the sun goes down.

We have a couple of these headlamps. Cheap, and super bright. They have a zoom function so you can concentrate the light as needed:

Then we use these as floodlights. Not super durable, but very bright and cheap, and the brightness is adjustable via dial.

Two is enough to light up anything but really big problems. We combine those with the headlamps and have been able to light up things like High Plains Drifter enough to get good video in the middle of the night.

Trust me, this is what you want. Most of the people who have climbed with us end up asking me later what lights we were using so they can buy some for themselves.

Buy one of THESE, then run around the bike doing a long exposure. It's called lightpainting.

I've used this with a T3i for video and it works nicely.

I picked up everything off Amazon (other than the camera which I bought 2nd hand off Craigslist):

• skeleton camera case (so the mic cable can connect)
• extra batteries/charger
• 160 LED light
• stereo condenser
• accessory bracket for mic
• tripod GoPro mount (to connect to the grip)
• camera grip
• USB mic adapter
