The reason for use of LED single bulb is to place a single plant under a table lamp in other rooms of a home. If what is called 'daylight' LED bulb could be used then this would be an inexpensive option for keeping a decorative succulent on a table in a living room.
However, I did find a full spectrum bulb which fits into a standard socket of a contemporary design table lamp which has an adjustable arm for height and direction of the bulb. This bulb is listed online byThere's a company I think called Renaissance. The LED full spectrumwhich makes this bulb is $44.00, and you can find it online at many stores. Perhaps this helps folks trying to keep decorative plants happy in the home.
