Agreed. Not bright enough or close enough to make much difference. Light intensity varies by the square of the distance. So if you have a light source 2" away from your plant and you move it to 4" away, it is now getting one-quarter the light. If you move it to 8" away, it is getting one-sixteenth the light.

you can get them cheap and the flexible goosenecks mean you can direct the separate bulbs at different plants. If your plants aren't big/tall enough to be right up close to the bulbs, put them on a table next to the lamp.
Here's a couple examples of lighting for indoor plants:
