These lights come packaged better then any box store lights on the market...important because the glass(s) are thick and heavy and are very good quality.  We have set the colors in many different patterns as well as all solid and have the rainbow function set now and this setting is very fun...each light changes colors randomly. They are brightest when set to the white but the option of changing colors sure adds to our outdoor decor. They come with a remote control to set the color and we have experienced no trouble using the remote to change the lights color from about 2 or 3 feet away. Very happy with this purchase.  Very nice that they are glass and not plastic - so no yellowing!
