Query: a great light

This is a great light. As noted by others, you need to buy the base seperately. The one I got has a rocker switch, not the rotary one shown. Also, the light mounts on top of the base, not underneath as shown. There is no directions for the new configuration provided and it took me a while to figure it out. I think the model has changed since the product photos. The base is not heavy enough. When you have the gooseneck extended out all the way, the base is a bit tippy. The light is very good. Plenty of power in white and red configurations.
