Second this. I don’t see the purpose of having a lantern any more after getting MTNelectronics diffusor. It works perfectly with slim tube 18650 lights like convoy S2, BLF A6 etc. Note that fenix pd35, nitecore P12 do not fit. They are a tiny too thick.
I bought like 5 diffusor tips for my camping trip last year. Worked great. I can easily hang the light upside down from a branch or in the tent.
