You mean Philips +R, not -R? (as Philips doesn't see any -R media... something about them being the leader of the plus alliance)
These do not have speed labels, which means that they're 2.4x discs. They're going to be either Ricoh R00 discs (great stuff) or CMC R01 discs (:Z). It'll just be a matter of luck-of-draw which one you get.
