Research lighting levels online or ask a garden store associate for help picking a lamp with the right luminosity. Plants from shady regions will require dimmer bulbs so as not to dry out the plans, and plants from arid regions will require extra luminosity. Indoor plant light levels are described as "low," "medium," or "bright" according to Bachmans, a floral company from Minnesota. Most lamps provide medium wattage light unless otherwise indicated on the box. If you're not sure what light levels your plant needs, consult the Plant Encyclopedia (see Resources) at MyGardenGuide.com. To use the Plant Encyclopedia, simply type in the scientific or common name of the plant, then click "search" to view plant details including ideal soil, water and light conditions.

Make sure the lamp you're looking at is using or is capable of using UVA bulbs. Ultraviolet light is emitted in one of three categories: UVA, UVB and UVC. UVA bulbs with shorter wavelengths, 315 to 345 mm, are ideal for sunning according to UVLamp.com. UVB bulbs are often too harsh, and shortwave UVC bulbs are even harsher, capable of killing bacteria helpful in the plant lifecycle. If the lamp you're looking at uses UVB or UVC bulbs, you can usually purchase separate UVA replacement bulbs---just find out in advance if the UVA bulbs will work. This important information is usually available on the lamp's packaging; if not, ask an associate for help.

Look for a good warranty. UV sun lamps are often more expensive than traditional lamps, so you want to make sure your product is protected under warranty for several years.
