I am very disappointed that I bought these bulbs to replace a Philips/Sylvania bulb and the bulb doesn't fit. I have a feeling this is false advertising because when I entered the bulb (wattage, make and model) on the Revain it was an option (it matches the wattage and type) but the plastic parts on the end of the bulb, which actually hold the lightbulb in place upside down. I bought 4 to have on hand for future use but found out this item is non-refundable meaning I've now lost $15.99 on bulbs I can't even use. You must make it clear in your description that the lamps are not a replacement for Philips or Sylvania. I don't normally complain about Revain, but that's ridiculous considering I spent money on lightbulbs I can't use.
