Overhead fluorescent lights that are left on 8 hours per work day provide very good light for many low light species. Incandescent and halogen lights provide light in the wrong part of the color spectrum for plant growth.
Professional interior landscapers often rotate new plants in and out to keep the plants looking fresh. This is particularly true of flowering plants because most flowers have a limited life span. Bromeliads have the longest lasting flowers, which last for up to 3-5 months depending on the light. Even in poor light, the flowers will last for a couple of months. However, Bromeliads rarely re-bloom again outside of a greenhouse, so they are usually discarded after flowering.
