Throw some light onto my ignorance

[Lynnzer]

I'm sitting scratching my head on this one guys 'n gals.
I have a new nano tank I'm putting together and am struggling to make sense of the lighting requirements.
The tank is a Waterbox Clear Mini 6 and I would prefer a clip on light that can be placed on a long side rather than an end, with the lighting element stretching side to side rather than across the width.
I would also like auto on/off with timer and a good colour spectrum. Maybe even controlled by an app on my phone.
I may just use CO2 sometime later but from a can rather than a usual built under bottle.
The tank will more than likely have only a couple of types of plant and I'm thinking more to Pearlweed for carpeting, java moss and/or Xmas moss on hardscape, I will probaly also place some anubia both red and green on the hardscape too and perhaps a bit of red small plants (not thought out just yet) in a back corner.
Price? Well I was hoping up to perhaps £80.
Any ideas please.

I like using LEDs to shed light on my ignorance. The ones that mimic the pattern of the day do the best - dim in the morning, brighter in the afternoon, and dim after supper again.
