Anybody using 250w HQI ballasts with SINGLE ended bulbs?

I'm wondering because Sanjay's tests show HQI ballasts with SE bulbs have a significant PAR advantage over DE bulbs (probably mainly due to the fact that SE bulbs can be run unshielded). Yet I rarely, if ever, see someone running SEs with HQI.
