Well it turns out, the HS20 has autosensing voltage from 100v to 250v. An adapter is all that's needed.
Switched it on, and (once again) WOWee!!! This things rocks. It's very bright. I don't have a light meter handy but oh yes. This projector has no problems outputting a very bright image. I slapped in SSX 3, 16:9 format. Klablamo!!! Sparkling whites and a gaming experience I'll never forget.
Prelimanary reports shows pixel misalignment. I'm projecting on a white wall with ambient light. I get a green tinge on the left side of the focus screen and on the crosshairs. Not enough for me to send it back yet. I'm gonna enjoy this baby a little bit longer.
