Lighting for a lean to shed

[Jupiter01]

I want to put some lights into this lean to shed. As seen here, it is not very wide and around 6 metres long. It has two sets of double doors and will have a bunch of shelves, internally.

Can I please have recommendations on the lights I could use for this. I am taking a feed from an outdoor light above and hence, can position these wherever they are most effective.

Thanks in advance.

Wiring these in 20mm conduit and want two lights operated by their own switches. I don’t think there is any option to continue a cable through this light and out the other end into the next? This is for the live feed going to the next switch.

In which case, do I take my live feed into light switch, switch cable to first light and then live out from switch to the next switch?

Will I be able to push 3 x 1.5mm cables through a single 20mm conduit?

Thanks for your help.
