As an early lighting collector, I 've always wondered how people lived through a new lighting, for example Auer gas mantle around 1890, fluorescent lamps around 1950, etc.
Here we live a new technology of lighting at its begining, and it's very interesting.
Many techical solutions about leds themselves and about collimators, electronic regulation, etc. are to be found, so each review merits to be read.
I for one, I don't read each review, but I try to combine a global overview of fans' reviews and thinking and a global observation of non-fans' use and understanding of such led lamps (for example, none of my friend takes care or is aware about led overdrive or heat).
Obsession for us, yes, but not more than divers, scientists, pilots, etc. who also have their magazines and forums!
