Hello, I have 4 T5s that are around 17 inches above my plants. What do you guys think is the best heigh for that? Also its about 48 inches long, how many plants do you think I could have growing comfortably below that?

I think T5's will be round a while for growers that don't need high illuminance and aquarium enthusiasts etc.Hello MVcowboy,
I do a lot of my veg under T5 HO lighting. Also I pop all of my seeds under it and root my clones under it. I really like T5 lighting. It also gives off a bit of UV which is great. Node spacing is nice and tight as well. I like Sunblaster T5's personally.
I use four 48" fixtures with the Nanotech reflectors added on. Under this 4 bulb fixture I veg four plants quite comfortably. I finish their veg for another two weeks under CMH once they move into the tent before switching to flower.
17 inches above your canopy is a bit too high. I usually stay within 4-6 inches.
No complaints.

That's flat out and only people like the flashlight modders run LEDs to maximum. AFAIK LED growlight emitters are deliberately under-powered to extend their life, so they use more emitters to increase luminance.I bought my T5s from Lee Valley Tools. They were the Sunblasters with the Nanotech reflectors. They have stopped selling the fixtures, although they appear to still be used in their plant stands. I had to really look around for replacement tubes. I did find them in Halifax at a specialty lighting store. If I wanted something other than what they had in stock, I would have needed to buy in bulk. I forget exactly how many, but it was more than I would use in my lifetime.
Except for a mini greenhouse (plant tray, dome, light) our go-to gardening center (Halifax Seed) no longer carries any florescent lighting.
Home Depot only carries one or two types of T5HO bulbs in each size.
The Sunblaster 48" T5HO lights only put out 5022 Lumens when new. They consume 54 watts. Their luminous efficiency is 93L/W, or about half that of the LEDs on the market today. The five year cost of ownership for the T5HOs is more than double that of LED lighting.
I have one of the 16 fixtures that I originally bought left. I use it in the tent with my 'blurple,' to take pictures of my plants for posting here.

The way I understand it is if the fixture is HO then it will accept either the florescent or the LEDs. If it is not a HO fixture then some rewiring or a different ballast might be necessary.So the led bulbs require removing the ballast or rewiring right?
I also use T5 HO along with 400W HPS/MH and some FAR-RED LEDs total just over 600w
they are also set on a SUN-RISE / SUN-SET Schedule so they come on and go off in stages
first photo all off
second photo only the T5s are on waiting for the HPS to start
Since I run red and blue spectrums at (VEG/FLOWER) i have to change the
full spectrum UVA/UVB Annually but the Red & Blues are every 2 years (only run half grow)
I originally was using Only a 600w hps but found I can get better lower growth with the
200w of T5 Side lighting
@Old Salt looks amazing!
