4 inch recessed led mount for open ceilings

designed this model so i could put led lights in my unfinished basement with the plans of installing a ceiling at a later date. these work extremely well and have no issues with them after 2 years of use. below is the link to amazon with the lights i purchased.  i used drywall screws to attach them to the floor joists.
