The Davis lights use a cadmium sulfide light sensitive resistive type photo cell for light detection, not a photo-diode (so I am a bit nit picky maybe ;-) ). The function is similar but will use a bit more power than a diode. The Davis lights also use an incandescent bulb for the 'anchor light' function (some Davis lights also use leds but not for the main light). For the same amount of power used by the light as the Davis you can get an LED anchor light 'bulb' that also has built in light detection and will be far brighter and last longer. For a comparison photo of a Davis light and an older led anchor light model in the late evening see www.firststarled.com -Ken _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://www.liveaboardnow.org/mailman/listinfo/liveaboard To subscribe send an email to [EMAIL PROTECTED] To unsubscribe send an email to [EMAIL PROTECTED] The archives are at http://www.liveaboardnow.org/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
