Ficus are great beginner trees! Adam Lavigne has a good blog on ginseng ficus. I will have to look it up for you. Some in the hobby have a hiccup with them. But they are great beginner trees. They have potential as well. Adam had a few blog topics on your species. I chose one. But feel free to use his search engine.I have 3 Bonsai:
Juniper
Ginseng grafted Fiscus
Dwarf Grewia "Star of David"
That is, if kept indoors, do Bonsai have seasons?
My experience with these three bulb clamp set up was not impressed. T bulbs which are more old school worked better for me than this set up. My tropical and I stress tropical do 18 hours of lights on them. Not 12, and I half wondered if that was the hiccup in that clamp set up I purchased when my tree outgrew the grow cart which has T bulbs. I now have a hydrofarm grow light with a LED corn bulb in it for this tree. Because it sulked horrible with the set up you see in the image.
As Ryan asked...what species are you growing inside?
The below set up was horrible for my growing experience. My knowledge on bulbs are only what I've used.

They were horrible for bougainvillea. Who need bright light. But even thrived under old T grow bulbs. They do look the same...as I had. Good to know they are helpful to lower light plants. Epic fail and my bougainvillea sulked through winter. It's the only reason I went all out and offered it the light system as found in my cold greenhouse for when spring arrives and saves me an early two stepping. Thanks for the information on those gooseneck lights.I have what looks like the same 3 gooseneck LED light. I grow a couple of orchids under it. The lights are on 12 hours a day 365 days a year and it's the only real light they get. They seem to be doing fine

BUT...these are lower light orchids. About the same light conditions as African violets.
When I measure my lights with a lux meter at the height of the leaves in that picture, I read ~12Klux. Full sun is >100Klux. These lights are not bright enough for most trees
