These are $10-$15+ at most places online, I believe they use either XP-E or XR-E LEDs with TIR optics (no reflector). Single mode with 5 hour run time.
Actually I think you could be right, I didn’t take notice of the pic and assumed it would be the same as the others I have seen.
It’s hard to tell from that pic but it does look like a el-cheapo LED.
