Lighting hours

[Welearn]

Hi,
I have a tetra cascade globe set up with just a few Anubias nana plants for my granddaughter. The lighting on this globe are nine basic led bulbs with the filter pumps and lights on together mount to 4.1w power consumption. Would having the lights on for 6hrs be sufficient? Or less hrs? Any advice would be appreciated. She only wants to keep 2 small shrimps as it’s now been cycled. Thanks
Simon

I Think 6hrs is a great period to start with

Thanks Zeus for your reply.The most I would go too with the basic lighting would have been 7hrs max. I will keep it at 6hrs I have no ferts, the parameters are as Good as I can get um. Just a water change every 2weeks. If you look at the profile photo you will see how it looks
