Plant & Aquarium is, probably, a GE fluorescent tube which is pretty good for growing plants. Slightly weird colour, but certainly OK for your plants.

Sunlight is a meaningless term. Lowes appears to use it to refer simply to the colour temperature of the light. The tube itself could be anything, good bad, or indifferent.

Believe it or not, I found a much worse selection (and higher prices) at Lowe's than at Home Depot.
