Ok so I love these Nova Lighting Tambo pendants - HOWEVER. Wayfair really needs to work on confirming specs when selling products (hence the 4 stars instead of 5). There are so many inconsistencies with the specs. For example, it states these require a medium base A19 bulb sold separately- that isn’t the case, they are equipped with an LED diode that has the option to switch from 2700k all the way to 4500k. Wayfair did the right thing by refunding me in full for the bulbs I purchased for these pendants that I simply did not need. Additionally the size listed on the Wayfair site is inaccurate. Installation was a breeze. They are really lightweight and fit right in my space.
