Many of the reefers have write to ask on how to DIY a LED light fixture for an aquarium.
Although there are a few write up here and there in this forum
But there are still many not sure what they need for the DIY or what components they need
and how each component look like.
So I hope to take this opportunity to do a simple illustration and some step by step illustration
for those interested to DIY the led light themselve.
