I want to remove the old tubular flourescent lights in my kitchen, and
light the kitchen (ambient downlighting) with recessed lights. I do have
access to the attic above, and there is insulation. I have an 8'
I've been looking at the different housings, trims, and bulbs at the
stores, and looking for information online. I'm overwhelmed with all the
products, but underwhelmed with the lack of general information. I can
find places to buy and product specs, but I don't know what to use.
I assume the most common size of recessed light is 5 inch. For my use,
I'd get a housing for insulated ceiling. I guess I could get cans for
non-insulated and push the blown in insulation back. Does it make a
difference? Or should I just go with the safest?
Since I do have access to above the ceiling, I can use the cans with the
joist spanners, but I could also use the can that are used for remodeling
where you can't get above the ceiling. Does it make a difference? The
cans with joinst spanners look to be sturdier.
How far apart should lights be placed? I like a well light space. I also
like the higher K temps, but this may not be possible.) I know this
partially depends on the bulb types and wattage, and trim, I use...
Bulb types...this is the most confusing of all for me. PAR is parabolic
aluminum reflector? Does a PAR 30 mean the beam has a 30 degree spread?
Are all PAR bulbs halogen? That is, are there incandescent PAR bulbs?
I've read that PAR halogen frosted bulbs eliminate hot spots and shadows
that non frosted PAR halogen bulbs can cause. Yes?
BR means binary reflector? What's that?
Watt for watt, or lumen for lumen, do the non-flourescent bulb types cost
about the same to run?
I've seen all types of trim. It appears to me that the most light would
be gotten by using a trim that allows the bulb to be flush with the
ceiling, rather than up a few inches or more into a baffle type trim.
I'd love to use flourescents, due to their low energy use, but I don't
see this as possible with recessed lighting. Anyone aware of a modern
looking flourescent type fixture, other than long or circuline tubes in
enclosures that hang from the ceiling?
Is there anyplace you can direct me to learn more? I have looked quite a
bit, and the more I look, the more questions I have.
