T5's are actually quite cheap for how much light they output, especially with the larger fixtures. The power efficiency isn't great though, so they output a significant amount of heat (CFLs output even more.) I use DIY LED light bars for my plants as shown in this guide: orchidborealis.blogspot.com/2016/11/samsung-linear-led-module-h-series-gen-3.html They're close to twice as efficient as T5 bulbs and take 10x as long to fade, though it is a fair amount of work to set up. With a recent price drop on the 2' strips I think the setup cost is comparable to T5 fixtures though.
