I would recommend either a CFL or LED bulb, and yes it can definitely handle the heat from those bulb types. I would not recommend any variety of incandescent bulb.
These cans are flexible
Refer to the manufacturer’s recommendation in the junction box for the recessed light.
Yes they can BUT, you need to make sure that the LED bulbs in your fixtures are rated dimmable bulbs--they are more expensive though. I have 6 fixtures on 1 dimmer and they work fine. You also need to be aware of the maximum wattage your dimmer switch is rated for and then you can calculate how many of a particular bulb/fixture that dimmer can control.
Compatible with Lutron or Leviton dimmers.
Depends on the light bulbs you use, if std a std dimmer works, if you use LED bulbs get an LED dimmer.
There are little "junction boxes" built onto the light with enough room in them to wire them in a row with quick connects. I installed 8 in a row in my living room ceiling this way, no pigtails.
You will need the cable clamp, 3/8 works fine,
I installed these in my basement. I looked on Home Depot's website to see if I could find just the trim, but I couldn't find it. I know they have them in the store. Your best bet is to go to the store. Sorry I couldn't be more help on this one.
Yes you can change the bulb and I would recommend an LED bulb daylight for the most light and nonn-yellow appearance !
