Aqua Clear Refugium Lighting Question

[Etcool]

I will be setting up an Aqua Clear HoB filter as a small refugium on the back of my nano tank. The only thing I plan on keeping in there is some Chaeto and some live rock rubble. Now my question is on the amount of light that the Chaeto will need to grow well. I plan to use a clip on light from Home Depot with a 6500K CF bulb in it. There is two bulbs that I am currently looking at, one is 10W and the other is 19W. I want to be sure that it will have enough light but I also do not want to fry it in the small space. Any input as to which one would be better or any other lighting solutions that could work better would be greatly appreciated.

Thanks for the help!
