These pull 1.65A (200MS) per strobe, and are not self-contained. There are others on the site, but none are self-contained.

The point that is the real sticker is that all the strobe (even bright LED) are going to exhaust a 9V or pair of AA in a really short time, certainly less than a typical flight, on the order of a couple hours I would guess.

A guy in our club tried a set that ran off ship mains, but they weren't really visible in the daylight.
