ΦΩΤΗΣΜΟΣ 50 ΛΙΤΡΟΥ

[Raven]

Eχεις δικιο ! δεν την ειχα υποψιν την λαμπα της Hagen και συμφωνα με το σκεπτικο οτι λιγα κελβιν= προς κοκκινο/κιτρινο και πολλα κελβιν= μπλε, υπεθεσα οτι η λαμπα ηταν για θαλασσινο.
Φαινεται ομως οτι τα κελβιν δεν παιζουν παντα ρολο στο χρωμα του φωτος.

In saltwater/reef aquaria, color temperatures are an essential part of tank health. Cooler temperatures are seen as getting through the water better, providing essential energy sources to the algae hosted in coral, that sustains it. Because coral receives intense, direct tropical sunlight, the focus was once on simulating this with 6,500K lights. Higher temperature light sources have become more popular as their success became widely known...first 10,000K, more recently 16,000K and 20,000K. Meanwhile, actinic lighting is used to make the somewhat fluorescent colors of many corals and fish "pop", creating brighter "display" tanks.
