Waymar83 Cam,

Clean up in ailse 7. I guess there was one guy who had time on his hands last night...

(do you simply delete these or leave them there?)

Waymar83 Thanks Dalton!

What you've done is exactly what I was hoping/planning to do on Waymar.Thanks for the leads. Enjoy the Carnaval! We are not far away in Georgetown but have not made it to TT for Carnival yet.

I will however be going to one of the Cricket World Cup Super 8 matches in Guyana. Cheering on the Canadian team! (which will not make it past the preliminaries but at least ranked 14th! (out of 16)

Will you catch a cricket game while down here?

SensiBulb

Waymar

I can answer your questions for you as I have been trying different kinds of LED lighting on Quietly for the past three years.

First, don't confuse todays LED's with those of even a year ago! Huge improvements have been made. Your questions:

1. The color of the light produced by the SensiBulbs is very "warm." It reminds me of the light that comes from a kerosene lanturn.

2. We have several (11) SensiBulb's on our boat having replaced all of our dome lighting with them. We used two SensiBulbs in each fixture in the salon, and one in all the other dome lights. We are very pleased with the results. We find that we can turn on as many lights as we want in the evenings and still draw less power than one of our old lights. This has made living aboard much more like home.

However, I would not recommend the SensiBulb LED's as replacements for your reading lights. The SensiBulb LED are a little too warm!

Instead, we found Magnum Ring lights from DR LED (http://www.doctorled.com/p2.htm) that make wonderful reading lights. They are bright and more like a standard incondecent light in color. We use two sizes of the lights from Dr.Led. For reading lights in our bunks, we use the MR11 lights in both the Bayonett and G4 mountings as required by our fixtures. In the salon we used the MR16 lights to go in our larger reading light fixtures providing more light for the larger area. We like these light so much that we installed six of them under the cabinets in our galley. Four might have been good, but we wanted lots of light when working in the galley. Just like home!

3. All together we have 11 SensiBulb overhead lights, four MR11 readings lights for the bunks, three MR16 reading lights in the salon and six MR16 light for the galley. We also have an LED Tri-Color/Anchor Light and LED Running Lights. The only incondecent lights on the boat are the spreader lights.

We are very please and our typical energy consumption in the evenings is now only 2.9 Amps with the boat as bright as back home!

Doing this was not inexpensive. However we use far less electricity and our home is bright and inviting in the evenings.

LED's don't be Mis-led

Leds are quite attractive from an energy management standpoint. What they do well is deliver a high intensity focused beam with very low power draw. So they can light up a navagational fixture, create a spot beam for reading, but they do not provide very good area lighting. One measure of light output is a lumen. LED lights are much lower in lumens per watt than flourescent bulbs. To get the most interior area lighting per watt look to flourescents. There is a new technology cold cathode ray tube technology that promises even better results but I have not located a viable source yet. So for me it's interior general lighting - flourescent, task/reading - LED, and Nav - LED. Good flourescents can be purchased from Alpenglowlights.com even with a led night time option.

Good luck with your studies.

Waymar83 Bill,

I am considering changing all the lighting to LED. I have three questions:

1) Is the "colour" markedly different (e.g. I prefer incadescent's warm yellow to neon's cold blue) What about these LED's?

2) Are they bright enough to replace reading lights, cabin lights etc.?

3) Is the power consumption really that much less if you have a signicant LED array to make it useable?

For example, most of us have a neon in the galley and in the main cabin. the other areas will vary. Have you replaced these with LEDs as well?

Bill Mc I have 12 of these bulbs onboard. When I'm on the hook I leave most of them on. Not afraid of the dark but high powered drunk stinkpotters running with no lights for excitement. 12 bulbs burning 2.8 amp draw.

I should at least get a Tee shirt....

Fair Winds,

Bill

capecodphyllis 'Expensibulb' would be more appropriate.
