Nice looking build so far, I wish i could see it done step by step. almost convincing me to build one for my 20 which is outfitted w/ only 4 ho t5. since im wanting mainly lps long term about how many LEDs would be needed to match or exceed the t5s that i have in there now without going way overboard? also cant you rewire a fixture later on to add more? sorry for the highjack
