Yes, but the price of that spray is the same as a whole new MF drop-in. And that's not including shipping. Not worth it for me.
I'm liking the dedomed XM-L, without a doubt it throws further, and it cuts through fog and rain a bit better too due to the warmer color. It's a whole new light now.
I do miss the floody version though, that is nicer for night walks, which is why a new drop-in is in the mail together with skyray S-R5 body :).
