Review on 🌤️ Cloudy Bay Dimmable LED Track Light Head, CRI90+ 5000K Daylight, Tiltable Track Lighting Fixture, 40° Angle for Accent Retail, White Finish, Halo Type - 3 Pack by Besim Kahsar

They are delivered individually wrapped. They are a bit tricky to install as they fit snugly. The base rail module has a slide lever that must be pulled down before it can be rotated counterclockwise into the guide. Only the handle was used for installation. I didn't want to damage it with water pump pliers. Eventually they sit down and sneak a little. Make sure they are where you want them. They can then be adjusted to the desired angle and rotation. Great little lights! If they last as long as they promised, they'll outlive me. In addition, they replace non-LED lights that use more energy and produce a lot more heat. [enough to discolor and melt]. They work great with the dimmer I have and at full power. Very happy with the purchase. More importantly, mom is happy, and when mom is happy, everyone is happy.
