Seeds lighting temp humid for seeds

how many watts of light does seedlings need. and how many hours of darkness and light does seedlings need.

Hello,
Seedlings would prefer at least 16hrs of light. Must be more than 12 light 12 dark.

Seedlings can get by with a single 100w cfl bulb, a 50w grow light, etc. The seed has enough energy to provide a bit of growth.
