In the photo forum I posted some pics of a project to convert from battery draining 1A incadescent cabin lights to efficient .058A Hella LED modules. Hope you enjoy it. Ron Mehringer s/v Hydro-Therapy

pretty cool Ron
You have been busy over the winter. Every time I go to my boat to do something, I end up going sailing. Maybe next winter I'll get the guts to trailer the boat and leave it in my driveway to work on. I did put a couple of fans by the compression post though. I was thinking of putting in a florescent fixture with a red and white bulb for more light and using leds in other areas. Liked the tiller to engine project also. Simple and effective. alan

Great light modification Ron!
I appreciate your documentation also. It makes it easier for someone to get it done rather than just admiring yours. Thanks, Joe C. in NC

Lights, Camera, Action
Nice job Ron. I modified mine to include red leds for night sailing. Kept the original for bright lighting. I did all but the V Berth light. You have been real busy. Outboard steering bracket, LED lights, Autopilot, and now I see Anchor mods. I will have to check this all out. Bob Gravenstine S/V Gravyboat

"Efficient" LED'S ??
Ron, I was considering LED's too, since they are going in everywhere these days; traffic lights and even the garbage truck tail lights. But didn't I just read an article in Cruising World this winter about lighting on boats. It said that LED's were not that efficient. They liked flourescent best. Is my memory failing....too?

Efficient LED's - reply
Jim - The most efficient light source at this time is the compact flourescent tube. Halogen is next followed by LED. So, why would I call LED's efficient? Mostly because modern LED's have the ability to provide very "white" light even at very low power levels. The 10W bulbs I'm replacing use 14X more power than these LED modules. If you ran an incandescent that low there would be very little useable light and it would be very yellowish. It's in these sort of low power applications where LEDs come into their own. A larger cluster of LED's could put out more light than a standard tungsten incandescent, and use less energy, but the advantage wouldn't be huge. Another key advantage in marine applications is the ruggedness of an LED. It is unaffected by vibration and shock. It also has a life of about 100,000 hours. That's why a few companies are working on LED anchor lights. You'll never have one burn out on you. To learn more about LED's and other light sources, checkout the CandlePowerForums (click the link below). We're a bunch of flashaholics who love LED flashlights.

A little action.
Bob - The rudder/motor connection and the lights were pretty easy projects. The autopilot still hasn't arrived (getting very bad service from Defender US) and the anchor is on the todo list. Necessary projects, like refinishing my woodwork, have thus far been neglected. Hope to get to that soon. By the way, have you splashed Gravyboat yet? Ron Mehringer s/v Hydro-Therapy

We're in business.
I splashed the Gravyboat on the 8th of this month. All projects are completed but I now am thinking about an asymetrical spinnaker to compete with my boat neighbor. He has a Catalina 250 and just got a drifter so I guess I will have to keep up. Bob Gravenstine S/V Gravyboat
