I have a 350 Carver aft cabin with g4 halogen bulbs throughout the cabin. I want to replace with warm light LED bulbs. How do I read the specs to determine the brightness equivalent to what I have now? I did a Google search and am more confused than when I stated.

What color are you looking for? For example in my flybridge the lighting is all red LED. The decorative surround lighting is electric blue in the salon the overhead lights are red/ white.
I would tell you to get the warm white with the highest LUMENS output. The good units have voltage regulators so they really will work with a wide range of voltages and remain bright.
Here is where I bought most of my replacement LED lighting for my Sedan Bridge. http://www.yachtlights.com/search.asp?keyword=g4+LED&search=GO
I can tell you be careful this place has everything and can drain your bank account if you go crazy buying all the cool quality stuff they sell for boats from Wire to LIPO4 LI battery systems.

They are inside the cabin so just warm white light.

A number of things mainly the number of clusters and the wattage. There are also LUMENs charts but I wouldn't waste my time. Count the LED # of clusters and look at for the max wattage for bright or fewer clusters of LED's and a lower wattage for less light output. The cool thing about LED lighting is if you use quality built units they will out live you and the boat. They also draw a small amount of power for the light power they produce.
When I built my sedan bridge I had about 24 fixtures that were Halogen if I turned on all the lighting inside the boat I drew almost 20 amps resting. Now that boat has approx. 30 LED fixtures and draws less than 4 amps resting. This is a tremendous savings in AH's for the house bank once you convert to all LED.
I'd do the running and anchor lights as well but they need to be done as a fixture not a replacement LED for the old bulb.

I bought cheap 15 led bulbs warm white on ebay but I didn't think about the fact they they were polarity senitive I ended up installing many of them upside down to get them to work. Needless to say this upgrade greatly reduced the light level onboard this year the bought 15 led bulbs white not warm and made sure I got bulbs that are not polarity sensitive, I'm very happy with these new bulbs I wasn't thrilled with the warm white it seemed to be more of a yellow light and just didn't provide an adequate level. Once again I bought them on ebay I forget what I paid but they were cheap like 20 for $30.

Dave I hate to say this cause were friends but that's what happens when you buy cheap chit!

I bought a couple of LEDs from MarineBeam, an Edison base and a bayonet. So far, so good. They have a good selection, and prices seem competitive. (I defer to BillyIII if this company has shortcomings of which I am not aware.)

William, they are the same quality this is also a good source for LED replacement fixtures and lighting.

Billy I paid a few dollars more the second time and I have to say I'm real happy these are still a fraction the price of what one would pay at any retail store.
 
What's bothering me is that you can't tell how bright they are until you buy them. It seems like they should give a "watt" equivalent. If they said a LED bulb was a 40 watt equivelent, you would know exactly how bright it was.

I looked at them in WM stores displays and also many boat shows. I really like Lumatec for high power LED outdoor spreader lights. They also make some good underwater high power LED fixtures. My LUMATEC radar arch lights are about twice as bright as my old 60 watt Halogen lights were and they only draw 3.4 amps.

I thought you were just complaining about the lack of light or poor performance?

Maybe this will help? 40 watts is 450 LUMENs and 60 watts is 800 LUMENs.

Lightbulb Watt-to-Lumen Conversion Guide

We all know how much light a 60-watt bulb will produce. But the brightness of new CFL and LED lightbulbs are measured in lumens, not watts, so here's a chart to help you do the conversion.
The other useful number to know is the temperature the LED light is operating at.
One last comment it;s getting late for me I think you would really be happy with the Imtra line for interior LED lighting.

Billy what I was saying is learn from my mistake the second purchase even though still very cheap work great and give a good amount of light. What's important is to make sure you get none polarity sensitive bulbs!

Resistive one's like you bought the first time can be a real problem. Watch this video.

Lots of info on the marinebeam site. Here about color temperature (~2700K is "warm") and about lumens (brightness).

+1 Chris Marinebeam/com really has their act together in my opinion. I have purchased LED's and various other marine power products from them over the years and always found them to be responsive.

I converted to using MarineBeam exclusively about two years ago; have pimped them here a few times. They have some other pretty cool products on their site too. Got a terrific 12v charger cord for my MacBook Pro for only 40 bucks, for instance. They really understand boats.
