can a 120/277 volt compact fluorescent light fixture be installed in a 120/208 volt system?

Most major lighting manufacturers (Lithonia, Columbia, etc.) have made the transition to what are known as mVolt (for multi-volt) Ballasts in the last few years. these ballasts can have pretty much any standad voltage up to 277v applied to them and they will function properly.
RE: 120/277 volt light fixture
Correction: mVolt ballasts are designed with single phase power in mind (a hot and a neutral). As 208v power is "two phase" I don't think they will function properly.
Here is a link to a GE spec sheet:

I would be hesitant to put an mVolt ballast on a 208v circuit though, as all of the ones I have seen state 120-277 with no mention of 208v.

Standard commercial power in the US these days is pretty much all either 480-277 or 208-120 3 phase 4 wire wye connected. This makes both 120v and 277v phase/neutral whereas 208v is phase/phase.
When they say 120-277, they could be indicating they are designed for either of the commonly used Flourescent Lighting voltages, not that they are good for a range of voltages.

In the Land of Lawsuits, there should be a large waiver or caveat if that wasn't the case.

I spoke with Osram-Sylvania, and their Uni-volt (mVolt equivalent) will operate with phase/phase 208v applied.
RE: 120/277 volt light fixture
For instance, single pin lamps use one of the pins as a switch and the ballast must be wired so that the hot lead goes to the switch pin. (The socket has two contacts which are bridged by the pin on the end of the lamp when it is inserted in the socket.)
The approval may not cover an application with two hot wires.
