Nora LED Retrofit Diamond Series
I received a display a few weeks ago with one of these LED recessed can retrofits from Nora Lighting. It is a great product, It is easily converted into an existing 4", 5" and 6" recessed can of there are new construction models available.
You save up to 75% energy, and it can dim better than any LED I've seen all the way down to 5%.
The retrofit is available in 2700K(warm white), 3500K(cool white), and 4000K(day light) and in either a baffle or a reflector trims(both shown above are reflector trims), and they are available in 7 different finishes.
You will have to see to believe how great the light output is on the LED and how well it dims.
Oh and it comes with a 7-year limited warranty!
