From what I see, the /54 probably designates the halophosphate daylight. The CRI would then be somewhere between 72 and 75. Wink

Yes, the dual segement color code, used for the halophosphors and the deluxe white phosphors. The triple segement color code, used for triphosphors.
Today, this lamp was discontinued in favor of the triphosphors version of it: the Master TL-E Circular which have better CRI and efficiency.
Also, in the Philips online catalog, all of the T12s that appears, are only american lamps, meaning that Philips lighting Europe (The original company) completely ceased the production of T12s.

Philips also use the three letter code for some metal halide and mercury lamps.
