Exactly that I think the products are questionable especially the LEDās and the Drivers however one of my drivers in the custom tank cabinet with the 88L tank has worked solid since I installed it altho compared to this tank itās low light levels so less heat, and the number of LEDās are less meaning the drivers are not pushed as hard calculating how much W you need is key thatās what I did and found this driver that supported my target W with some + or - to spare
Feel free to message me or tag me if you do decide to make your own and need some advice/assistance I will be happy to help
Thanks mate, will do. Currently contemplating leaving the two 39w tubes and putting in something in addition but not sure how that will look light wise.
