Has anyone had any luck with them with corals
So there is a rule of thumb for Watts per gallon for fluorescent lighting.
What is the rule of thumb for LED lighting ?
I can't get a straight (or even crooked) answer from anyone ????
The problem with a watts per gallon rule, is not all LEDs are created equal. When the first came out, it was approximately 70 lumen per watt produced. However, as lighting LEDs are constantly being refined, the Lumen has increased significantly from 70Lux/watt. In addition, lumen represent total light emmitted, including infra-red and ultra-violet, not just the light we are concerned about.
LED lighting is still relatively new to the hobby, perhaps in the furute someone will create an accepted rule. Right now, many people are running 120W fixtures every 2 feet and seem quite happy. For me tho, as I have a tank 2.5 feet deep, I will wait until I can afford a pair of dimmable 160W fixtures so I can get light to the bottom.
