I have a 1/2″ plasterboard/ 1/4″ plaster ceiling that is too thick to accept the remodel can light hangers that only fully extend in 1/2″ drywall. Does anyone know of a technique to install cans in a plaster ceiling?

Keep looking, some remodel cans let you do that.
I have put in Lightolier retrofit cans in 3/4" plaster ceiling with no problem.
Can't you drive a screw through the holes inside the can, through the plaster/lathe to secure it? It's sort of a lowrent solution, but it should keep it in place.
don't think he has lathe.said 1/2" plaster board, i interpreted this to be 18" wide sheets of "drywall" put up horizontally which the plaster is applied.no wood lathethat's the way my house is done.

Right. No lathe. Plasterboard is like blueboard from 1950. I am thinking of using remodel cans and modifying each of the wings (cutting them down) to accept the 3/4 dimension. It is time consuming though.

Same with the house I'm living in, built in the early 70's, no blue board. It's not drywall though I don't know what you call it. And it's a little thinner than 1/2".
Er, bobl, it's the ceiling he's talking about.
It's gypsum lath(e). Some of the heaviest *!@#$% known to man.
well, a ceilling is just a horizontal wall :)

around here it's known as Rock Lath.

I know for Iris lights you can get plaster lip extensions that allow ceiling thickness of up to 2". This being Iris, the PLE alone is about the price of a can from Halo or Juno. See if your lights have something similar.
You only have about 3/4" thickness to deal with- we've done these allot with remodel cans. Around here, the 1940's and 50's houses used "button board" under the plaster. Button board is gyp board with perforations about 3/4" dia. After you cut your hole for the remodel can, run your hand along the back side of the gyp. board and knock off any plaster that oozed through the buttons.
Your can should slip right in. With a thicker cieling you'll have to push the spring clips a little harder, but they are designed to accomodate varying cieling thicknesses.

Button Board is all over here too (Denver).
