Kessil A80 enough for SPS quarantine tank in the 5-10G range?

[Muffin87]

I'm getting either the Eshopps Deskmate 5G or the Waterbox 10 G as a coral quarantine for easy SPS:

• Pocillopora (Cauliflower)
• Seriatopora (Bird's nest)
• Stylophora (Cat's Paw)
• Montipora Digitata (Finger)
• Acropora Yongei (Bali Green Slimer)

Do I need a a Kessil A160WE 40w, or can I get away with a Kessil A80 15w to quarantine these corals for 76 days?

I'd love to get a different fixture, but kessils are the only ones that have a knob to change the spectrum on the fly from totally blue to white.
The QT tank is near my desk, so I can't use white light all the time (I did that already, it blinded me).
But I am going to need to change the spectrum from totally blue to white, each time I inspect the corals in QT.

Another thing is that Kessil A80 and A160we are quiet, which is essential on my desk.

I would be more worried about keeping the parameters stable with that small of a tank. Light should be fine.

Im gonna use automatic water changes and lid to prevent evaporation
