This meets the regs for drone flying at night, which I would assume is the same as part 103 regs.

That seems to be expensive to me. I build this kind of kit, . I think that it would be possible to do it yourself very much more cheaply. The 60Hz strobe rate makes no sense. That would look like continuous illumination.
Take a 555 timer Ic and a Mosfet, those will come to under $2. A five Watt white LED and Lens will come out at under $5. Suitable circuit will be easy to find on the net. You could almost certainly construct your own in an evening.
Ah! Not 60 Hz, 1Hz. That makes sense.

At the very least you should have an ultralight-style strobe. Even then, you will find that they are still very hard to see by other air traffic. I still liked the idea of having one. At the very least I thought it might help keeping larger planes from landing on me from the rear on final.

I have built a number of high power strobes for experimental aircraft over the years. It is a simple project. At one time a local Radio Shack would carry all of the parts:
Strobe tube
6 volt to 120 volt transformer
3055 transistor
trigger coil
strobe tube
NE2 neon bulb
Silicon Controlled Rectifier (SCR)
Large electrolytic capacitor (typically 300mfd at 500 volts)
some resistors based on other component values.
Total less than $20.00
You can get clever and build sequential strobes with not much more effort.

Voila, a very bright strobe. There are probably a lot of circuits out on the net. Trick is finding the parts without spending more on shipping than parts. But it is fun to do, potentially dangerous, and useful, everything that appeals to a pilot.
What more could you want? Danger, fun, useful, inexpensive? Move up the evolutionary ladder from Pilot to Builder Pilot to Avionics Genius Builder Pilot. How many A380 Pilots can build their own strobe.

Or you could just do what I did and mount a high power flashlight to your helmet, and you get a twofer! Strobe and landing light.

Kuntzleman sells a fully self-contained strobe for ultralights that weighs 7 oz, and meet FAR 103 requirements. If you have a voltage regulator on the engine electrical output, it will run straight off that, no battery required.

I had one on my CH-1 until I replaced it with an all LED strobe.  https://www.kestrobes.com/single-led-strobe/

This guy apparently didn't have so much luck with that strobe. Not sure whats up with that. The drone strobe I mentioned weighs 15 grams.
