Ok that's much better that you edited your coments but should at least apologise to easilyled - he even welcomed you to this forum. Every few months someone will stumble on this forum and start this discussion about why is x light so much $$$$. You are asking a reasonable question and If I may I will give you some idea of why things work out very expensive in custom fabrication especially titanium flashlights.
Custom machining is a very expensive business. There are some people on this forum who will charge $30-40 to mill a small 1.5mmx6mm trit slot on a torch. Why? That is is because it takes time to set up the machine and it takes several passes to actually mill a slot that is only 1.6mm in depth. This may take 20-25 minutes to do which is where the money is spent. This is simply to carve out a slot in a titanium torch. Titanium is a fairly easy material to work with but it needs very hard and expensive tools such as carbide. These tools are not cheap, they wear out quickly and require extra time and effort due to the hardness of titanium.
now to custom build a complex titanium flashlight such as the 007 or the Tri-V would take hundreds of hours of planning, drawing, making prototypes, refining the design and that is just the shell of the light. You still need to get the electronics worked out, the reflectors, Lenses and everything else that goes into making these work - the guts. This is also a trial and error process. These range of spy flashlights are no ordinary flashlights - they have complex programming built into the drivers of the flashlight. This itself would have taken many hours to design and test to ensure that the functionality works. The assembly is even more fiddly - try taking one apart yourself. The maching of the parts cannot be done in a single operation and require several stages of production.
When I first stumbled on the spy Tri-v my initial sentiment was - you must be kidding (price!!) ..... But having purchased it and looked at in detail and then going onto to making little parts myself to mod it over the last few months I now realise that everything about the light is very complex. Even the battery cap is complicated. The inventor could have just made a very boring battery cap but he chose to make it a puzzle and very interesting in the way it works and operates the latch. If you try to replicate this you will realise that it is not a easy task to design this from scratch. It could have been made much more simpler but that would have reduced the 'wow factor' for people who appreciate the design that has gone into it.
in this day and age we find that things are mass produced and that creates assembly plants which drive costs down. Things are constantly designed to keep costs down. Somethings are sold for just a few dollars because there is very little mark up. These rely on volume sales. Others are sold with a high mark up because there is a demand for the item. Custom items need to be more expensive than assembly plant items as they are produced in small numbers and are very labour intensive. This of course means that hand made things are very expensive. Try a handmade suit, shoes and you know the cost just jumps up.
I truly do not know what the profit margin is for the range of spy lights but I am happy to pay the inventor his asking price as I feel that his efforts are worth rewarding by the way of purchasing his lights. There is no sense in questioning this - if I do not feel it justifies I should simply look elsewhere. I don't question why a Picasso is worth $100 million plus as I have no qualification or means to argue about this.
Is it absolutely necessary to spend $2800 on a flashlight? Well I guess it depends on what floats your boat. Some people might spend $12000 on a one way first class transatlantic flight for what most people on cattle class will pay $1500. It is down to prefetence and what you are willing to pay for. Others might feel that a Yacht is a good means of transport while somebody else might settle for a bicycle. I guess what I am trying to say is that it is not easy to put a value or worth on things.
Bottom line is that if you want the most complex and highly engineered titanium flashlight out there which also doubles as very useful flashlight (the Tri-v has a emitter for all sorts of lighting requirements) you won't find anything more handy than a Tri-V to fit the bill.
Does this help answer your question?
I was trying to figure out why they were so expensive. I didn't know they were custom built from a guy.
