I have the CFL recessed lights in my kitchen but i want to change them to LED, some one at home depot told me that i will need to change the can. Can someone help or guide me to a video or instructions how can i remove the old can with the new one ?
The question is if the can has a built-in ballast for the florescent light. If the can uses standard screw-in CFL bulbs, then you can just replace the bulb (and probably the trim ring) with a retrofit LED module designed for use in a incandescent can.
On the other hand, if the florescent light has two or four pins to connect into the can, then the can is designed specifically for florescent and includes the ballast for the florescent light. In this case, you will need to replace the can (or modify the can, removing the ballast and rewiring it, which is probably not worth the effort).
