What do you do if you want to replace your mixture of 4"and 6"recessed fixtures from incandescent or fluorescent to LED?Consider the LED module from DMF Light.
DMF Light has come up with an LED module(see fixture below)which accommodates a 4"or 6"trim.So you just buy the module and select trim size and finish.
This is available in either a remodel version or new construction.It's about time someone has come up with this solution.Thank you DMF!There are more options for more specific installations.
