flashy crusade

i posted the t1 gem from voratum gauntlets in generall discussion, because it was it was just misscommunicted, but now...
which part of the talent tells me that I do light damage?

"You demonstrate your dedication to the light
with a measured attack striking once with your weapon
for XXX% damage, and once with your shield for
xxx% damage.
If the first strike connects 4 random talent cooldowns are
reduced by 1
if the second strike connects you are cleansed of 1 debuff."

alright, it sais "damage" instead of "weapon damage".
but when you use % it has to be weapon damage right? and it doesn't say "as light damage"...
