These were a few years ago from my Amazon days (ā501s/ā502s/C8s/ā98s).
I went on at length about the race-to-the-bottom death-spiral of quality. All my ā502s I bought when they were still good, using either real Crees or at least good LB clones. Cheap drivers (resistors, no regulation), but decent emitters, albeit on the cool side, āthough not Angry Blue. Even the switches were really good, no flicker or anything on my daily-driver.
Alas, it was the same for C8s, too, when I started getting āem. Good quality.
Later, about in a 1-2yr span, quality went down the toilet. Never got more ā502s as I was hip-deep in āem, but as far as C8s, thatās when they started getting cheaper and cheaper. Crappy featherweight Al pills, plastic reflectors, cheap switches, E-sized emitters that may have been clones of LB clones, would barely put out 3-digit lumens, more like 70-80, āthough concentrated into a pencil-beam. Really bad. Hell, even to use as a host, the body would be lightweight, obviously thinner and lighter than earlier.
Anyway, my first C8s were great, later ones crap. I complained to Amazon and/or the seller (forgot which), and got a partial refund for the crap ones.
So nowadays, I wouldnāt risk getting any generic light from Amazon, period.
Youād probably have a much better chance getting something decent from FT, especially if listed as āgenuine Ultrafireā(!).
