I would like to show you two very interesting high power flashlights from the Chinese brand Shuolide. I found them some time ago on 1688.com which is the wholesale variant of Taobao. They are available also on Taobao but at a higher price. They seem to be available only in China.
SLD-12C 12x XHP70.2 70 000 lumens
SLD-24C 24x XHP70.2 150 000 lumens
They both have fan cooling like the Imalent high power flashlights but they cost half the price of a similar Imalent flashlight.
The SLD-12C has 12 XHP70.2 and four 21700 batteries. The XHP70.2 are genuine. I own the 5000K variant which I ordered through a shopping agent. The 5000K XHP70.2 are slightly green and it is long click to turn off but for the rest the flashlight works well. I have no Imalent flashlight to compare it to.
The bigger SLD-24C has 24 XHP70.2, eight 21700 batteries and is specified with 150 000 lumens. It has 150mm head diameter and three fans. If the lumens are correct you could position it between the Imalent MS18 and the MS32.
