I have read and heard many things about HL lighting. Some source says that they prefer better lighting than humidity, other says that they need hight humidity and high lighting. My terrarium is 53L and the size is 59cm(lenght) X 35cm(height) X 30cm(width). (I probably have to change it to bigger if I success well )
I have a spare aquarium lamp with one 15W fluorescent lamp, but I think it's too weak. Another thing is that the lamp should heat the terrarium at day, and at night temps should cool down. Our cellar is always +12C warm, except in hot or very cold days the temperature can reach 9C to 14C. In my opinion one 15W lamp can't be able to heat the terrarium to about 20C or higher. How important the day temperatures are? What if I reach only to 20C at day, is it bad? Thought the night temps are more important with HL than LL.
So should the light be 2X18W or more? I've read that T8's produce more heat than T5s so I probably have to use T8s. Since the terrarium is about 60cm long it cant have 100cm lamp with higher watt amount.
I haven't been able to test the lighting, because the cellar don't have a contact box, yet.
