Dual application recessed lights......

[TcDuhon]

I have seen these and am a little confused. They state they are dual application and should be used with the 3" rule or insulation can be in contact. Is there different ways of installing them that would make them one or the other and what do you look for?

thanks,

They are IC rated up to a certain wattage .

OK. So, if I am reading it right. It will be approved for IC up to a certain wattage. If wattage is increased than the light will automatically shut off.
So I would not need to worry about these types having IC?

The thermal cutout is in the fixture regardless of IC or non-IC.

Really no different than a regular IC rated recessed light with incorrect lamp type and/or over wattage lamp - fixture heats up and bimetal switch shuts the light off ... light cools down and bimetal switch turns light back on.

Example: fixture rated for 75R30 lamp works okay with a 75R30 but overheats and shuts of with a 75 watt A19 lamp. The R30 lamp is a reflector lamp and reflects both light and heat out. A19 lamp does not reflect either light or heat out - fixture heats up and shuts off.

What is confusing about them is that nobody follows the instructions when they install them (O.K. that is true for just about everything). Inside the can they have two rated wattages. When installed as an I.C. fixture the part of the label with the higher wattage should be removed and then the 3" clearance to insulation label should also be removed. Maybe there are variations to this, but when I first came across these that is what I read from manufacturer's instructions.
