Will my Christmas cactus respond to lamp light rather than sunlight?
I just acquired a Christmas cactus. I don't have a window with indirect sunlight to put it in. However, I do have a table in the living room with a lamp that's on most of the day because my 91-year-old Dad sits in there watching TV for most of the day. Will the light from the lamp be sufficient for my cactus?

Probably not. If it is an incandescent bulb, then it will not provide near enough light, and too much heat. If it is an LED then it will need to be about 5 or 6 inches from the light bulb.
There are horticultural bulbs for plants that will fit into a normal socket, but still, you will need to hang these about half a foot from the light to a foot. A google search for horticultural LED will give you many results that will fit a standard socket.
