10 gal. refugium - ok to use 27W LOA?

[Enkidu]

I've got a refugium as a section of my sump. I estimate it to be 8-10 gallons (section is ~ 8" x 15" x 14" with 4" DSB). I was going to get the 65 watt LOA fixture but since the refugium is so small would the 27 watt LOA be enough?

Anybody who's running the 27W bulb please chime in. Thanks!
