It was difficult to find these specific bulbs and I am so happy to have found this vendor online. They found the light I was searching for and provided a few options for the type of bulb. They are working well and match the others.

Purchased to replace non-LED bulbs in a chandelier. These bulbs are great, brighter than the original bulbs and are dimmable.

So disappointed. To be clear NOT in the company or service. The company shipped the product I ordered. Just in the product. I wanted to replace a crystal cut bulb with a LED one. Well, the refractive pattern on the ceiling that makes these light bulbs "extra" and worth the charge doesn't occur with the LED bulb like it does with incandescent ones. The quality of light and everything else seems fine but it's just disappointing. There's not benefit to getting crystal-cut LED bulbs. If you want that effect, get the incandescent ones. Otherwise don't pay more for crystal cut.
