Marinetrader's great Solar Panel thread and website mentioned the current draw of an anchor light as being around 18AH overnight.* In an attempt to reduce this load a couple years ago, I learned of an LED anchor light made by Davis Instruments called the Mega Light Masthead light.* http://www.davisnet.com/marine/products/lighting.asp
This light comes with two bulbs - 0.110 amp for low current draw and 0.320 amp for extra brightness.* The light also features a photocell that turns the light on at dusk and off at dawn so I no longer forget to turn it off and notice the anchor light shining at high noon.* I wasn't impressed by the brightness of the low current bulb.
In a quest to get even more efficient, I installed a Marinebeam Davis light 6-LED replacement bulb.* http://store.marinebeam.com/dameledre.html* This bulb is brighter than the brightest Davis bulb and consumes a meager 0.041 amp.* The folks at Marinebeam now market the whole package here for $35.* http://store.marinebeam.com/utanliwiduto.html* There's also the option to upgrade to a 15-LED bulb for even more brightness.
I can attest to the brightness of the 6-LED bulb.* It is surprisingly bright and very white.* The fresnel lens of the Davis Mega Light evens out the light distribution very nicely.
