Hi has anyone used Exo Terra Day+ Night LED Light Fixtures for their dart tanks. I am thinking about getting one, but wanted to know others thoughts about them first! Other alternative is a Exo Terra Compact Top with a green gro LED bulb. Right now I have the Exo Terra Natural Light Full Spectrum Daylight and compact hood. I heard that LED's are better for plant growth. Darts don't need as much UVB. Can I switch out fully for the eco terra Day/night LED fixture. Any thoughts?
