Other than the HPL's integrated heat sink and thus requisite different socket configuration, it seems to me there's little difference between the GLA and HPL lamp families (the GLC's lumen output is slightly less, but perhaps that's due to the HPL's extra 50 Kelvins). GLAs cost more generally, but that's likely a factor of economy of scale, as there's more demand for HPLs. I think everyone has to admit the socket situation is much better now with a GLA in a TP220, than it used to be with an FEL in the TP22.
Looking over the spec sheets, it just dawned on me (even though I'm not really a fan),
Can the Altman Phoenix be used with Dimmer Doubling technology, if equipped with a 77v HPL? Does it have 750W and 77V holes in the same locations on the socket plate?

This might give the Phoenix an advantage over the GLA-based SPX, or the Hi-Brite FastFit-based Leko Lite.

Humm. This has not been my experience for the HPL burners that have the spring clip that keeps the lamp firmly seated in the socket. I have no records, but my strong impression is that those sockets ( with the spring clip) have a much longer life than the standard bi-pin socket.
Now I have had issues with S4 using older burners before they put in the spring clip - and with S4's where the spring clip was missing. But if the spring clip is there my maintenance experience with the S4 has been much better than the old style bi-pin.
We are still buring FEL's in all of our fixtures and socket failures are not really that common when you consider how many fixtures we have and how hard they are ran. We are currently swapping out with the TP-22 Osram sockets, not the 220 and have not had any issue with them.
