Review on 🌈 SpiritLED Standard Intermediate Color Converter Set of 6 Pieces by Robert Berio

E17 bulbs are hard to find in my area so I decided to buy an adapter to use medium cap bulbs in my ceiling fan. I use LED bulbs so can't comment on the heat resistance but for LED they work fine. Note that they extend the lamp by about an inch or more, not a problem in my case, but keep this in mind if you have a fully enclosed fixture.
