Sharing the details around my dive light I know giving someone on ebay $200 for a brand that you have never heard of is always iffy so here is one that I can vouch for at least.
All Ebay and Amazon links are below. It was shipped to me directly from China, the ebay seller had great communication and i received it about 10 days after I purchased it.
I only use this light for river dives, and I have been very happy with it, the batteries keep the light extremely bright for about two hours. Overall its a great light for the money.
My current setup with this light 9/2017 Update:
