I use an LED flashlight for my bike light. The one I have I got cheap from Amazon or maybe that slow-boat import business in Taiwan (I have two of these, similar but not exactly the same).

Shopping for another, but ... I'm confused.

What are the hot-shot LEDs nowadays?

I see a lot of these flashlights on Amazon and elsewhere, and I can't sort out the wheat from the chaff without some help.

The flashlight I'm using now says Cree XML-T6. This is a couple of years old, so ... must be something better by now.

LED experts, please weigh in.
