Building a LED housing to be low profile to fit in a FRP recess is going to be difficult with a reflector to get a narrow beam. As an example, a typical reflector size for a Vero 29 is 110mm (4.33") diameter and 67mm (2.64") deep. This is massive and you still need housing and heat sink fins.</div><div id="yui_3_16_0_1_1437943666092_21469"><br></div><div id="yui_3_16_0_1_1437943666092_21468">I am wonder if we really need a focused light or is a flood light adequate?</div><div id="yui_3_16_0_1_1437943666092_21467"><br></div><div id="yui_3_16_0_1_1437943666092_21465">Cliff</div></div></div><br>_______________________________________________<br>Personal_Submersibles mailing list<br><a ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org" id="yui_3_16_0_1_1437943666092_21463">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br><br><br></div> </div> </div> </div></body></html>
