Ditching Hybrid, Going Full T5?

You could hang a 48" long bar from your existing arms and then attach a 48" fixture to that bar. I think you would be much happier with a 48" fixture.

I think you have a killer set up currently! I’d keep it over all t5’s…

Unless you're going to expand to 48" I wouldn't bother to upgrade.

You can buy 3 48" LET kits and make a hollow frame from wood from home depot and will cost about $350 total. This fixture is light and will hang from your current light hooks.

LET reflectors are wide and have the same coverage as a 8 bulb Sunpower.

Going this route also gives you options to add/mix in some LED bars in the future. Make sure you make the frame 24x48 or even slightly bigger by an inch all around.
