It's a matter of taste to a great extent, but my
question would be why you're putting recessed
lights in a bedroom in the first place. They're
designed for down-lighting; perfect for kitchen
counters. For ambient light or general room lighting
they're limited and wasteful. And in old houses they
can sometimes be risky due to the heat produced.
(I'd never leave the house with recessed lights on.)
If it were me and I were forced to use recessed
lights, I'd use as many, as small, as possible, so that
a "glowing ceiling" effect might be achieved.
I am about to have recessed lighting installed in several bedrooms (standard
size) of my house. 4 lights in each room should do the trick. Here comes
the hard part-- incandescent or LED? 4 inch, 5 inch or 6 inch cans? I just
think 6 inch is too big and ugly (though it seems more standard than 5
inch). I am afraid that 4 inch cans won't supply enough light. LED
installation is much more expansive than incandescent and I don't think the
LED cans look that good.
Here is my question. Could I get 5 inch incandescent installed, then switch
the bulbs itself to LED bulbs? Is there any electrical problem with doing
it that way? Are there LED bulbs equivelant for a incandescent bulb that
would fit a 5 inch can?
