I do own a number of higher value torches, but I'm still happy to be a member of BLF and have a chat about torch lights, theory, diy tips, and just stuff in general.
I think its comes down to the type of people that are in the forums. Many here are far more open minded to the concept of various budgets, and its this that makes this forum more forgiving for the newcomer. The question is how open-minded we are to the definition of budget. There are many members at BLF that have come from another place.
As has been said by others as well, budget lights are made to a price, and sometimes cannot offer the features such as a UI that doesn't rely on the tail cap power switch alone. This is not pointing the finger at budget lights, but its something we must understand is just the nature of the business. With this in mind, higher budget lights have the resources to offer additional features beyond just producing light, and discussions about these aspects would allow a better appreciation of torches in general from an engineering and design point of view.
A not quite do budget light section may allow more open discussion of other lights, which would allow others to read about what features are available, and possibly bring fourth ideas which can be considered and maybe even incorporated into the budget lights (light the magnetic ring control system)
At the same time, I am not too keen on forcing a separation of budget and non-budget lights, we have to start considering things like; what defines the threshold, what happens if a light is considered to be in the wrong section...
At the end of the day, the question is, how do people feel about the discussion of a $50, $100, $150, $200 18650 XP-G torch, which is likely going to be outshined by a $20 Fandyfire. If the forum can accept that these torches be discussed in the same forum, without bringing on a rant about "how/why would anyone spend that kind of money", then maybe a separate sub forum isn't required, however a separate sub-forum would more openly permit these discussions while keeping the forum neatly defined.
I do enjoy talking about more expensive lights as thats where I tend to focus my resources, but I started with the budget lights, and maybe its cultural, but finding a good bargain always seems to satisfy the inner soul (of illumination) I would like to know what others feel about this?
