Good. That's a compact fluorescent bulb. Cool white is fine. I use the "daylight" which has a 6500K and probably very near identical.
To the plants. You asked about easy care; that can mean a couple of different things to different people, but I will go on the basis of less maintenance. In general, avoid stem plants; they grow fast which means regular trimming/pruning. I just finished responding to a similar question in another thread, so I'll copy over what I wrote there.
I would look to the swords. Several are in our profiles, Echinodorus bleherae
as a specimen plant would be lovely, with Pygmy chain sword
or the similar-looking Sagittaria subulata, Dwarf Sword
, and maybe crypts (Cryptocoryne species) though these can be fussy and "melt" if things are not just so. Corkscrew Vallisneria
is different from the others, and does quite well esp in medium hard water.
Floating plants are beneficial to fish and water conditions. Ceratopteris cornuta
if you can find it, or if not, the stem plant Brazilian Pennywort
is ideal left floating.
I find the above (except for the crypts) very hardy, easy plants. All are in our profiles [click the shaded names]. Depending what nutrients occur naturally from your tap water (regular weekly water changes) and fish foods, you may need to use a general fertilizer. I recommend Seachem's Flourish Comprehensive Supplement as the best I've found. It is not really as expensive as it might seem, since you use so little of it. Example, only 1/2 teaspoon once a week for a 30g tank.
