I think while the idea of wattage is still relevant, the more important stats for a grow light for a small group of carnivorous plants are lumens and Kelvin.
More lumens means the light can be further away from the plant, but at the same time, a low lumens light just means you have to put it closer to the plant, so it means you don't have to get just a very high lumens light. 2000 or higher is often sufficient for a typical range of about 6-18" away from the plant, depending on which plants.
A grow light's Kelvin's light temperature range will include red and blue but if you get the Kelvin range that is the daylight range, 5000-6500 K, then it would be sufficient also.
Keep in mind that some people talk about wattage and red/blue color range because they may be growing large amounts of plants or want vegetative growth, such as in a hydroponics setup for food or other ... umm.. entertainment purposes. Many beginning carnivorous plant lovers may not even be in the category yet to buy these very expensive grow lights, but can instead, buy cheaper lights that fit the bill.
For example, there are some T5 or T8 LED / Flourescent light bulbs that are not termed as grow lights, but because of meeting the minimum lumens and Kelvin measurements, would work just fine for your indoor plants.
