For the umbrella plant, yes. But the hibiscus needs a lot more light than that, they're really hard to keep inside. They do best in full sun all day, so that's difficult to emulate with bulbs. I've never had any success with hibiscus indoors, but my umbrella plants do great with 2 5000k lights, so 6500k lights would be even better.
I buy the linear fluorescent ones. Usually, if you go to a Home Depot or Lowe's they're located towards the "bright white" spectrum, over on one end of the light bulb section. They may be labelled as "daylight bulbs" or something similar, but you want the light temperature to read 6500K (kelvin). They tend to be either Phillips or GE brand.
