thermal info of various metals:
Brass has about 2/3 less thermal conductivity than Copper,
Brass has about 1/3 less thermal conductivity than Aluminium.
otoh, Brass has about 16 Times better thermal conductivity than Titanium. :student:
imo, buy the metal you like, dont worry about thermal conductivity… just dont use your light in ways that generate high heat… Medium modes are our friends… LOL
I recommend a ceiling of 120/150 = about 350 lumens, and turn Turbo Off, regardless what metal the TS10 is made of.
