Hi,
Not sure if you got a respose, or not. I replaced the halogens in my track light(s) over the center island with:
GE 4 watt (15W) MR16 Bright White Indoor LED(s)
I bought them from the "Big Box" store #48 races for
here
They just "twist" into the fixtures. Run a LOT cooler.
Hope this helps. Still luvin' my "Suh-Weet"[/url]
