first light installation help

[bigthink68]

hello masters

I have a 60x40x40 cm high tech tank I just installed
cuba plant in front and mini parvula planted in the back
I'll plant red plants at the back
what I wanted to ask you

1. what should be the height of the light from the aquarium

2. how should I adjust the light and how many hours a day should I keep it on?

Recommend 15-30cm from light to water surface.
6-8 hours.
A newly planted tank, recommend set RGB percentages around 20%-30%, add about 5% each week for growth.
