I am doing exactly this with my yard light controller, which is working
fine.  The lamps are 12VAC and draw around 8-10A total (haven't measured
it still, but it's heavy).  I'm using IRLZ34's, Rds(on) of about .046 Ohm,
they get a little toasty but work great.  Working schematic (I think it's
up to date other than a couple of part numbers) is at
http://www.botkin.org/dale/yardlites if you're interested.  Many thanks to
Dave D. and other list members for helping me figure that one out.

When working with MOSFETs, gate voltage is your friend.  8-)
