Comes with the aluminum box, full set.
Slightly under a year (think it's 11 months or something), battery pack still have lots of go. That time i tested for ma_sha it went about 80 mins @ full power. (need a fan to actively cool it though LOL!).
Anyway, spare ballasts of 75W or 85W/spare batteries are easily available on aliexpress/ebay/CNqualitygoods etc...no issue.
Performance as mentioned is about ~80 mins of burn @ high power, just under 4000 lumens OTF and if you focus properly it throws pretty ok. It can be defocused for flood and < 50m use. Else if you use it at 10-20m, it attracts too much attention as it's too bright. :D
I have this thread here vs the TK70.

Selling @ 90 SGD, or about usd69. Local sales only. I cannot ship overseas as it's like 50 bucks SGD and besides the battery might be problematic to pass.
Reason for selling : just moving some of my lights....thinking of getting the Solarstorm 5 XM-L @ 2A. I have several 65W in Indonesia and could be bringing 1 or 2 back.
Can PM me and i'll give you my mobile number for dealing. (in the city / MRT stations)
