Product review (1 stars): Fooled me once.....
I had returned a similarly priced 4-pack Sylvania small appliance bulbs to the supermarket after deciding to go with this specific GE replacement bulb for the icemaker in my GE refrigerator.  It arrived today (3/5/16) and promptly blew after I screwed it into the icemaker socket and pressed the button to turn it on.  Upon inspection, I can now see that it's not a genuine GE bulb, because the "GE" imprint is missing from the base.  Even though GE had sold its bulb manufacturing division, the "GE" imprint is still required on the base of all the bulbs manufactured as a part of the purchase agreement with the new owners.
