About to start a project. I’m going to build a canopy that will hang above the tank. It will have leds in the middle and 2 t5 bulbs on both sides. This is the plan as of now anyways. So my question is does the canopy need fans to cool the bulbs? I’ve heard that the bulbs will last longer if cooled properly but I’ve seen the aquatic life led/t5 fixtures and there are no fans to my knowledge. Is it because two bulbs won’t get hot enough? I don’t know. What’s your opinions?
