There’s a good video review of hybrid led + T5 fixtures by BRS, which shows why & how the combination reduces shadows best. I’ve gone with Aquatic Life hybrids on my tanks as a result.

Ok sweet I’ll have to check it out
If you are wanting to take care of the shadowing I would go with T5. Reef brites look great, but they don't have the coverage of T5. One other factor is the coral you are keeping, if you are leaning towards sps I would go with the reef brite because of the coloration, if LPS and softies T5.
Fwiw,
I’m putting a 24 inch Aquatic Life fixture with 2x AI Prime HD’s over an Innovative Marine 50.
You could get almost the same PAR over your 40, using the same fixture with your Hydra 26, depending on hanging height of course.
I went with the 2 AI Primes due to the larger footprint of the tank. I can spread them as needed & they have a little more power than the 26.
Hows the tank working out for you?
What settings are you using for the 26? I used the BRS settings.
