My First flash light sunwayman D40A

hi all alex from Malaysia.
after gain many knowledge from this forum and i purchase my very first LED flashlight,(Cool White)
a Sunwayman D40A. extra with a sanyo eneloop 2450 pack off 4XAA and charger.
i do order a defuser and filter,but the supplier give me a nitecore brand filter and fenix defuser.
the filter i can just plug in bottom of the light and carry with pouch it provide.
but i having a question cause the heat sink was covered by the filter rubber will it be overheated and became malfunction?
and the filter are need to push inside or just slightly cover the top side?
sorry for a bad picture cause i used my sony xperia Z the camera default having a defect some dust stick into the CMOS censor.and cause like that.
feel some hot after turning turbo mode for after a few minute.

Put them just far enough on, so they stay in place. The heatsink is there for a reason so don't cover it up, when you have the light in a higher mode. With Low or Med mode it shouldn't be a problem, I guess. But with High and Turbo the light does get warm/hot.
