The two most important performance parameters for underwater lights are beam control and beam angle, both of which are primarily functions of reflector design rather than lamp type.
LEDs provide unique challenges to reflector design.
Total Internal Reflection optics are a second options for luminarie light control, with their own performance benefits and constraints.
Computer-based design software provides designers new tools to create custom reflectors to match specific lighting requirements.
