Xylem, gorgeous tank for a 14g. Really good example of what can be done!! I'd be a bit concerned regarding the mysteri wrasse and the lyretail anthias in such a small system but everything looks great.
I use a 150W HQI MH on my 20G, no issues at all, its 30cm or 1' from the surface. But i suppose, i do live in Ireland! Pretty cold here compared to Cali!
