Wellp, I’m hardly “hardcore”, as I don’t have lumenometers or time-lapse equipment to measure output, output over time, temperature, things like that, but more “Amazon-like” reviews: first impressions, impressions over time, and final words if perceptions change (something breaks, nifty feature I’d discover, etc.).
I prefer to edc the light at least a week or two, but if the mfr is kinda pushing for quick turnaround, then it’s strictly first impressions.
Besides, plenty of people can do beamshots, etc., way better’n I can, so best to look for their reviews if that’s what you’d want to see.
