Yes, it's a species of Lampyridae (firefly), but not the genus Pyrocoelia ( = Lychnuris), because it has quite a different pronotum shape. Pyrocoelia has characteristic, transparent "windows" on the fore half of the pronotum, not present here.
This is a species of the genus Vesta, which has quite a lot of species on the Philippines. Unfortunately, there is very little information on them on the internet, so I can't come up with a good reference, other than scientific literature.

Many thanks Dominik! ID now updated :)
