Is 1 T5 worth it?

[New&no clue]

I really like the T5 LED combo. On my RSR350 I have LEDs and 4 T5 bulbs, 2Blue+ and 2Coral+. I just got a Nuvo 30L. I had planned to do a similar combo of T5 and LED, but the tank is so narrow I think I would only be able to do one LED strip and one T5 bulb, probably a Blue+. I started to think is it even worth it. Would 1 T5 bulb really do anything? Just looking for opinions, or experience if some else has only run 1 light and found it useful.

for 30L I would just go simple with led. Any add on light will do something.
