Coralife has a 20" 1x28w Aqualight and Current has a 20" 1x40w Satellite fixture.
But, both of them come with saltwater bulbs. You can swap them out for 6700K, 8000K, 10,000K and a dual daylight 6700K/10,000K bulb.
Current also has a 2x40w Satellite and a 2x40w Orbit fixture. You'll need good CO2 for these fixtures.
