I wonder if you can still get these other than on eBay?

We've still got a few in our stores, and at least one street I know the inventory specifies SON-Cmft rather than the usual SNT lamps. But I think we stopped using them around the time we changed to electronic dimming ballasts.

Thats bad, those look like a decent high end lamp option that is great for some places. Wonder if it would be possible to achieve atleast some of the CRI increase with a normal SON lamp by little overdriving it without affecting the lamp life too much ?
