Lumens - John Martin

Converting from old technology (incandescent lamp), to new LED technology:
20 watts puts out ~190 Lumens, but only consumes about 2.5 watts of power.
35 watts puts out ~350 Lumens, but only consumes about 3.5 watts of power.
40 watts puts out ~
450 to 500 Lumens, but only consumes about 7 watts of power.
60 watts puts out
~800 to 820 Lumens, but only consumes about 12 watts of power.
75 watts puts out ~970 to 1100 Lumens, but only consumes about 14 watts of power.
100 watts puts out ~1600 Lumens, but only consumes a bout 22 watts of power.




LED's -
Michael deKraker

     I have had great luck with some Home Depot and Lowes bulbs.  Cannot remember the brand, $10 for a G4 1 watt and it is a dead ringer for a 10W halogen and just as warm.   Also I have Phillips G4's for about $10 which are very harsh but good in the galley for task lighting.  It is crazy-cool  to light the boat for a 10th of the energy.... Look forward to any new info.


(Editors note:  G4 is a plug type, and refers to the two prongs plug mounting type.  This replaces the halogen type bulb.)

We try to use all LED's down below. Here are the ones I have currently.

Lowes - Nice warm light, dead ringer for 10W halogen:

Home depot, $10, a cooler color temperature good for task lighting:

Really like these for head, $12:

LED - Bulbs - John Martin

For a local source for LED bulbs, try Peco Campers, 1852 Tucker Industrial Road, Tucker, GA, 30084.  From I-285, go out Stone Mountain Freeway (US 78) to Mountain Industrial Blvd, and see Peco Camper on left.


LED's - John Martin

      We replaced all of the incandescent bulbs aboard 'Carina', with LED's, a couple of years ago.  The cost of LED's has come down dramatically.   A couple of notes:

The kelvin temperature of a bulb, ~5500°, will be a bright-blueish-white
The kelvin temperature of a bulb, ~3500°, will be a warm-yellow-white (similar to incandescent lighting)
G4 is a plug type, and refers to the two prongs plug mounting type.  This replaces the halogen type bulb.


LED's -  Jeff Andrews

I just read the SSC page about LED lights.  You mention that 3500K is similar to incandescent.  In my experience LED “warm white” is 2700K – 3500K but to get a really realistic incandescent color, you have to go with 2700K.  3000K may pass but 3500K will be a dead giveaway that it’s an LED. 


LED's - Color - Jeff Andrews

For your enjoyment...  I find this to be pretty interesting.  I was trained on this when I was overseeing the calibration of televisions. It’s a bit technical for the web site but I thought you might like to read through it.  On the third link below, notice how each color temperature has a line drawn more are less vertically. Along the length of those lines, the color can vary and still measure the specified temperature.
 
I haven’t tried the app in the last link but I plan on downloading it and trying it out.  If might be useful for measuring boat lights and choosing LED replacements. 
 
 
 
 


LED's - Solar power lantern - Jeff Andrews

This is what we have.  We really like it. The only drawback is that it is not waterproof.  It looks like it’s been upgraded to be more water resistant.



LED - Inflatable Lantern - Teresa Gennette

(Editor note:  This is a very powerful & bright light.  This light will work below deck, above deck, and ashore.  Weatherproof.  Solar power, NO batteries.)


LED - John Martin

Lights -  John Martin

Make sure cabin lights are capable of switching between white and red.  Red light is used below deck, at night, to not destroy night vision.


Lights -  Michael deKraker

I have some new LED info.... Found some pretty reasonable LED and fixture prices here

http://www.sailorsams.com/Lighting_c_2216.html

A friend had to replace a recessed fixture on a newer hunter and this was where I found them. She ordered the LED version and is pretty great. They have all bases and configurations for reasonable $$$$... in a warm version similar to your source.



Lamps - John Martin

Another great source of lighting is Oil Lamps.  We have 4 oil lamps in the main cabin of 'Carina'.  They provide plenty of good light.  And, we also have an oil anchor light.  Some things to consider when purchasing an oil lamp:

Make sure the under side of the reflector is white enamel.   
Round, circular wicks give the most light. 
Wide wicks give the next best light. 
An ounce of oil gives about an hour of lighting, depending on how bright the lamp is burning.  
When storing lamp oil aboard, always store it in metal bottles, not plastic.  Plastic can puncture very easily.

Make sure the lamp has replacement parts.
