Too expensive unless money is no object.
That may seem to be the case, if all you examine is the initial price. However, it happens that the "expensive"ight will outperform and outlast cheaper lights in such a way that in the long haul they actually are cheaper to operate.
I have used both cheap lights and expensive lights. I prefer somewhat expensive (what I would call "value priced" items). What is really expensive is the light that does not perform when the chips are down. In some situations (caves) it can be a matter of life or death.
There are some lights that do seem to be a bit extravagant, more bling than practical working tools, no matter how reliable. But that is true of many items - think firearms, knives, canteens, stoves, etc.
