Have purchased two fig trees and I have a spot indoors as they are tropical/not cold hardy. The window light is not ideal unfortunately but I have (2) light sockets directly overhead on a 24 hr timer.
I can use any type of standard socket light bulb.

But I'm having the hardest time trying to determine what light bulbs to use. I've already heard indoor plants need 30,000 lumens (???!!) the compact flourescent bulbs I have currently in them appear to be putting out about 3500, at least a foot from the lights (50,000 up close, 10,000 or less a few feet away). I'm using a smartphone lumens detector.

This is making me think the whole project is doomed to fail..... can't seem to find anyone answering this question though plenty of people are asking online.

TaoTronics has a full spectrum grow light for indoors with high reviews here. However I don't know if this would work with a tree on the floor:

also there's this behemoth, but I just don't know

is there any standard socket bulbs that would work with fruiting figs? Can anyone help with advice... thanks much.
