I browsed through several of the Siam Square -malls extensively last year for the same purpose. I found a couple trekking stores (probably the forementioned TANK-stores) carrying a couple Surefires and Fenixes. The prices were higher than even here in Finland.
I also recall finding one dedicated flashlight dealership online operating in Bangkok, perhaps it was the TacticalThai CVLPA mentioned. They seem to have a proper website and a considerable selection.
Then again, at least in MBK one can find plenty misc. booths with random "tactical gear" from knives to optics and flashlights. However, knowing what you're buying won't be a simple task as the products are presented without packaging in heaps of other stuff. I don't recall whether I saw any cheapy brands that I recognized, but I'm guessing that a keen capability in recognizing at least the emitter would come in handy when trying to find anything worth wanting. It will of course also be hard to get the price down to any reasonable level as the vendors have developed "rip off" into the finest of arts.
As for flashlights....it's all junk, or it's good stuff at crazy prices.
Comparing prices from US with the thai shop that I mencioned above it's not so bad, for example for a T60CS it's like more 5%.
Anyway Europe is more expensive so for me looks it like a good deal...
Hey I know this is an old thread but I've been living here between Thailand and the USA half the time here and there for over 6 years now, but been in Thailand a few more months that I really have been meaning to, due to circumstances and really miss buying and getting new lights & modded lights online and getting bored with my small collection of custom and stock lights I brought with me. So really want to know if there is anywhere decent I can go to in bangkok to find some new high powered flashlights to either check out, buy or possibly even trade or sell? Hell im down to even meet up with a fellow Thai flashaholic to compare flashlights! Brought a few of my V54 small and larger high powered flooderes and throwers, and custom P60 lights as well so I don't feel too alone and incase anyone wants to check them out. But I'm getting withdrawals and need to get some new lights to feed the beast, lol. So anyone know any specialty flashaholic shops or a flashaholic meet up in bangkok Thailand? Or going to MBK is my only shot at finding something? Anyways, hit me up at [email protected] incase I don't get your message or reply here, thanks!
