I ordered 3 of the sebson G4 LEDs and can only report posivtives.
Since the "kitchen recessed lights" are constantly with us, I wanted the halogen bulbs (20W) Switch to LEDs. Said and done, the installation went relatively quickly, the old removed and installed the new, finished. Fits all wonderful, not even needed to expand the reflectors.
From the light I would say that they are a little brighter. Everything top! Hope the LEDs last laaannggee ..;)
