What LIFX lamps are what ? E.G. History?

I’m a bit confused by what lamp is what, what’s current, what’s old, what’s discontinued, what’s what generation of hardware.

The ‘Mini’ series seems to have been discontinued? Replaced by the same shape lamp ‘Color 800 lumen’ and ‘White 650 lumen’? Or these are identical to the mini but just renamed?

There is no replacement for the ‘Mini Day Dusk’?

Is there a way to tell on Amazon what is current and what is old and s/b avoided (or purchased if a good deal)?

It’d be great to have a chart indicating the various generations, what has replaced what, etc.

Thanks,
