how to distinguish an IC can from Non IC..
I have been trying to determine what I have in my ceiling in my 20 year old home. If IC, I understand I can fully insulate up against it and eliminate a draft in my room--True? I do see some insulation through the vent holes in this can and I'd like to add more....I thought the vent holes might be an indication that it was not an IC can but some research has lead me to understand it might be IC just not ICAT (air tight).
An IC can will have 'IC" in the model number---if I can find it.
AN IC can will shut off a bulb if it gets to hot. (There is such a shut off in my can, it says so on the label in there---does this mean it is IC?
An IC can is not necesarily air tight - there are still slots in the can---TRUE OR FALSE?
So, if I find the IC in the model number and it contains: IC or the thermal protection switch note, can I assume its IC and dump a bunch more insulation over it.
I am using a Twisty flood light that gives off less heat anyway but want to make sure it safe in case someone ever puts a regular bulb in there.
