This is actually a 5" light, not a 4". At on older Lithonia recessed lights, the distance from the outside edge of the baffle to the edge of the baffle is exactly 4". This is 5 1/4" from the outside edge of the baffle to the edge of the baffle. However, it's easy to install and bright. When I was out When I needed a work light due to lack of time, I put it in. But don't let the name fool you.
