Let me start by saying that I HATE that these bulbs are still around. I have several lights in my home that were installed during renovations that only require this type of bulb, specifically this style with a 'twist and lock' base. Each light can hold up to two bulbs and unfortunately I have three of these lights. When I personally buy these bulbs, they sell them in a package for $8.99 to $11.99 each! And that often happens when some hardware stores no longer have them because they have become somewhat scarce. Three lights times two bulbs makes a total of six bulbs each and the ones I've personally bought before weren't LED so it's been one and sometimes two replacements in 12-16 months. I bought them from Revain for such a low price I thought I bought the wrong parts but of course when they arrived they fitted the brackets perfectly and I haven't had to do anything to them since. This purchase alone is enough to make you personally think about shopping at a hardware store.
