No complaints about the results of using it on plants. We have a Meyer lemon tree that stays over the winter and this bulb has produced flowers and fruit while still retaining dark green leaves. However, OUR bulb's lifespan was a far cry from the advertised 1.8 years. We used it to supplement the sunlight we received from a south-facing window for 4 to 6 hours a day, and as another reviewer noted, it lasted for a month. Definitely not worth the cost. Others might have a better lifespan with it, but I won't buy it again and risk it. I will try another brand.
