I have a couple hours of night flying logged. It's very cool.
Here is the headlight I use:
http://www.amazon.com/Waterpoof-Outdoor ... 0+watt+led
The light is shipped with wires less than 1 foot long and ready for you to add a 3 prong plug. The ground wire probably isn't connected to anything. With the LED driver it will operate on AC 110 to 240 volts. I've found the drivers typically operate from 85 to 265 VAC.
Without the LED driver, it operates on 12 volts DC.
I've removed everything but the mounting bracket & bolts, the LED, 2 wires, the casing, and the reflector.
It's a wide angle floodlight so you need to get kinda close to things for it to illuminate well enough for video.
I usually hang it from the front/bottom of both landing gear with 4 zip ties and power it up after liftoff.
Done properly it stays pointed straight ahead and doesn't interfere with the gimbal.
If you mount it as I do, the angle is adjustable and if mounted facing forward, the light will point down when you travel at a high forward speed, that's part of the fun though.
Positive features:
* looks like I'm looking at a landing light on an approaching airplane, super freaking bright even at 500+ feet
* measures about 4.25 x 3.25 x 1.25 inches
* weighs in (as pictured) at 98.8 grams
* runs on 12 volts so I plug it into an aux power source on my FC40
* doesn't draw much energy and has not noticeably affected my flight times
* my bird can't fly far enough for me to loose sight of it
And the negative:
WARNING:
IF YOU REMOVE THE GLASS YOU MUST BE AWARE THAT THE LED WILL BE ABLE TO COME IN CONTACT WITH FLAMMABLE MATERIALS AND IT DOES GET HOT ENOUGH TO START THINGS ON FIRE, LIKE DRY GRASS.
I'm responsible for what I post, you're responsible for what you do with my goofie ideas.
I tried this:
http://www.amazon.com/gp/product/B00C4U ... UTF8&psc=1
I was able to clearly tell when it was pointed directly at me (against a dark background) from about 500 feet.
I'm not sure how well it would offer the same directional information in suburbia or in the city.
There wasn't much forward lighting but it got me home when I was a ways out there, then the flimsy wiring gave out.
Cheers
Hey Prylar, if you're named after a Star Trek character, how can you be older than dirt?
