Saw some LED Bulbs on special at BingLee SupaCenta Moore Park.
Was kind of in a hurry so didn't really check every type, saw some 350lm, 600lm, 806lm e27s, and some gu5.3 and gu10s. All $5 each.
I think $5 is a decent price for gu10s from a well-known brand. Bought a few myself.
Can't comment on quality since I haven't tried them yet. But the bigger bulbs were made in Indonesia instead of China if that makes any difference to anyone.
EDIT: Apparently it's not just this store: Link
