Have your EXACT model number!!
I purchased this replacement bulb for my SLVR410.  This is not the same model as the SLV410.  The bulbs I ordered and received had the plug on the outside of the ring rather than the inside of the ring and were unusable.  That said, I went straight to the manufacturer and they explained the problem to me and sent me the correct bulb for the SLVR410 which is replacement part number FB681.
