This recommendation for indoor lighting is because of David McPeters and he gets the credit for using similar products at his place.
I recommend the following product for indoor Tropical Bonsai trees or someones house plants. I have a very large buttonwood that is growing like mad and even flowering all over it. Other Bonsai trees are doing really great as well. It does produce a lot heat when in use so keep that in mind before buying. It does use a T5 bulb and NOT a T8 bulb.
