Changed out two bulbs. I had to change the second one due to this one being a bit cooler than the old ones. I wanted them to match.

They weren’t as warm white as the others I have in my kitchen. They are off to the side so people can’t tell. But I can see it has more of a yellow cast rather than red.

My outlet that requires this bulb is in an area that is seldom used. When it failed to work, I was surprised, but it had been in that device for a long time, so I bought a replacement bulb. I was surprised at the pricing system. The cost of 6 bulbs is almost the same as 2. I forgot the cardinal rule of dealing with electrical appliances: Is it plugged in? Guess what? It had become unplugged. Check your plugs, please.

Had to send them back as they didn't fit. Even though the numbers where the same ends where very slightly different. Had to go to Lowes and same number but they went in perfectly.

The bulbs give off a very soft light that doesn't look glary. They arrived on time, too.

Some of the lights light up but very weak and flicker, others won't even turn on. Not a single one in good condition. Don't buy this
