My 2p's worth
reselling far east imports would be a mistake
your USP's should be around, british build and support, flexible design, latest technology etc You should be competing against the "premium" brands Lumi, Hope, L&M, USE etc
someone commented above that you need to design a "bread and butter" range that creates the turnover and gets your light's out there. base on AA and AAA technology, lots of people have the batteries and chargers already
you need to look at how your business cycle works for the year, stock may be expensive but next day delivery gets orders. Why not get a student to do this years base builds in the summer vacation?
Arguably you need to look hard at the AA idea as well as sourcing your own batteries, one profit margin (yours) in a light set is better than 2
why don't you ditch the fins and get "TROUT" cut into the sides? It's your brand, make sure it's very visible
plenty of people will buy lightsets priced "right" (£120-150 all in seems to me a price point to aim at) that are quality pieces of kit, the Bastid's are disposable therefore you need to be within 2x-3x price at most
additionally DIY kits could be relatively easy way of increasing turnover
the comment about optics is right as well, R&D is your strength, use it
also get your lights in early for the magazine tests
there is "risk" in investing, but I would say it's limited, plenty of Bastid's won't restart next winter and their owners will need new lights and will want something that is more robust
looking forward to a well priced, high quality lightset storming the market for this winter
