They are bright, a perfect color, and look great in the light fixture. As you dim a fixture, the light usually changes to a warmer (more yellow) shade. They were encased in foam to eliminate touching another bulb or moving during shipment.

The product description for the 60w 4000k bulb is misleading. It says the bulbs are both 4 watt and 6 watt. A 6-watt led bulb is about the equivalent to a 60-watt incandescent bulb.

Cotanic's claim of a three-year warranty is empty. No response from manufacturer. Was contacted by provider and issued a refund.

Light is as bright as a 40ish watt bulb. Just remove the light and take it where needed. Haven't tried the included solar panels yet. I have it installed in our chicken coop and one light lights up 200 sqftt.

The hook allows to hang under a sink when working on plumbing. They are bright, portable and realiable. Highly recommend having these on hand for power outages.
