Fluorescent lights are the best lights to use for starting seeds indoors. Use one "warm" bulb and one "cool" bulb so you'll get the full-most natural-spectrum of light. Once seedlings sprout, give them 14-16 hours of light per day. Keep the lights about 4-6 inches above the seedlings. Avoid using incandescent bulbs to start your seedlings. These bulbs give off so much heat that your seedlings will suffer heat damage if you keep the seedlings close to the bulbs. And incandescent bulbs provide too little range of the natural spectrum of light.
