Although the first one of these that I received was DOA, the second one was perfect. Its much smaller than the rotating beacon that it replaced, but still is much brighter. The hardware, fit and finish are excellent. Looking at the old rotating beacon next to this new one, its hard to believe that the old unit was still legal.

I fly an electric Ultralight. I have tested 4 different sets of LED strobes or beacons, but none of them seem to be able to produce the kind of punch you get from a real discharge strobes. This one, from PSA Enterprises, produced the brightest light of all (helped by a large number of LEDs), but it hardly got my attention from 50 feet away, and it does not force you to look away. I have now come to the conclusion that - at least for now - LED strobes are not powerful enough to be noticed from several 1000 ft (landing lights are another matter - much more focused). I have Xenon strobes on order and will return these.

I am building a RANS S-19 and bought this with the intention of mounting it on the top of the vertical stabilizer. The picture includes a mounting container and a cover lens. All I received was the bulb. Im sure AC Spruce will make me whole on this but submitting review for info purposes.
