Yes Ven! Terribly sorry......Thanks for the info!
Hi there DT1,presume me its a Thrunite Catapult V3 white diffuser,its actually 58mm but fits nicely.
Will fit 60mm head on other lights too.I got it from the thrunite_shop on ebay.
It was 1/2 price of other shops asking $35,i paid $17 or in my money £10. Compared to my nitecore 60mm diffuser its far better made,fits more secure.......ironically i prefer the nitecore diffuser for........well diffusing:laughing: just(not technical here) has no imperfections on a wall or indoors(cant notice outdoors so not really important).
I would recommend it anyway,does its job well.
