I would no more want to deal with all those cells individually than I would want a Root Canal procedure. I probably have had a couple of those lights for 15 years. The lightheads anyway. The battery packs are mostly newer. They connected right up to the old lightheads and I can use the older chargers but the newer chargers are more sophisticated.

The light beams are round. I'm agnostic on the issue of round vs shaped beam, but you have to know that you are on the contrarian side of the issue and the majority of cyclists want shaped beams. Quite a few want generator hub power to boot, and that equals very modest overall light output. It's simple physics. You cannot get but so much light out of a 3W Son hub no matter what. But even allowing for some lumen inflation, my newest light the Cygolite 1200 sits on its helmet mount over two MagicShine 808's on the bars and that is plenty of light for this cyclist.

Probably any cyclist, because I have Macular Degeneration and I need a LOT of light at night. Way more than most cyclists that are quite happy with no light at all in the city, and were more than thrilled with the 110L Halogen lamps from back in the day. We don't need bleeding edge light fantastic from Asia because, beyond a certain level of illumination, you are becoming a road nuisance. Flashlights obviously were not expecting to be put on Two Fish Lockblocks and pointed at oncoming traffic in anger. I don't need to be that cyclist that carries an insane amount of illumination because they can.
BTW I know what LED chips are in the lights I use. Maybe you need to see what has taken place in the last 15 years of bike specific light R&D.
