Saw some interesting stuff at a chandlery last couple weekends:
 - 12V CFL fixtures with the tiny straw-sized tubes, like those used in LCD displays:  Straight, snaked, or embedded in transparent mini-fluorescent tubes of standard form factor.
 - LED arrays and fixtures for area lighting, spot lighting (some with white/red selectability for keeping night adaptation while at the navigation station), as navigation signaling and marker lights, etc.
(Appropriate, since chandleries started out as suppliers of marine lighting consumables - candles and lamp oil - before they evolved into convenience/general stores for sailboats and small powerboats.)
