I have not read through all of the posts for this thread but I converted to the G4-WHP6, bought from this site Super Bright LEDs - Bi-pin Base Bulbs. At the time all they had was cool white, looks like they have added warm white.They work grreat, easy to install.
Yeh, but how much darkness do you have now in return? They all seem to not put out as much light as a 5 or 10 watt halogen they replaced. I'm looking for someone to say that the unit they bought puts out more light than the halogen thgey replaced it with then I'll get interested again.
I too have a CCD 28, 2004 vintage. Bought some G4 based multiple light led's for trial and have been disappointed. Some of the LED's have began to flicker; have you ever noticed the new traffic lights that are using LED arrays, a good number have some of the LED's burnt out. I'm skeptical of this industry yet; I ended up replacing all my 10 watt bulbs in my CCD with 5 watt. Very little visual effect and my power consumption was cut in half, literally...checked them out with an ammeter (am an electrical engineer)

Gerry and all,
Your overall perception is not unusual, there are significant issues that come with LED technology, as you mentioned, some of the traffic signals from the early days are failing (mostly green) due to various conditions. As for small lamp replacements typical in our Airstream, some of the products are just plain junk, some are OK, but none are currently available that will perform at the lower color teperatures to be considered "exact replacements".
The road map for LED efficacy (lumens per watt) improvement has shown tremendous positive jumps, mostly in the lab and in more technical applications. Unfortunatley, the smaller white light applications have not translated into commercially available product yet, and some of the probelms you have seen (flickering) is probably due to improper heat transfer that results in premature failure. Most LED "bulbs" lack sufficient heat transfer because they do not take into account a systems approach to the application.
Most of the manufacturers in LEDs have not put much effort in halogen replacements at the 5 to 15 watt range, except the MR-11 and MR-16 lamp types, which do not fit in our AS factory fixtures. I have been waiting for the right repalcement LED lamps that are quality and will perform as lower wattage replacements for the bi-pin type halogens. Some of the manufacturers are close. I believe when they hit approximately 100 lumens at 2 to 3 watts, and a color temperature between 2800k and 3500k, with an appropriately size heat transfer, most of you will be pleased with the performance. The reality today is that our application is just not large enough to satisfy the business equation for LED manufacturers, but the time is near...just hold on a bit.

I am currently in the process of installing Dr LED, recessed 'spot' warm light LED units in the ceiling of our 78 Ambassador.
I'm installing them in conjunction with installing three new Fanstatic Fans from Vintage Trailer, the ones with the flat gray vent covers. It's easier to install all the wiring while the new vents are not yet installed.
I'm installing a total of 11 LED 'spots'...3 in the (mid) bedroom, 3 next to the sink/stove, and 5 forward above the gaucho. I'm installing them on 8 inch centers. They look good, and provide the AS interior with a 'modern' flair...IMHO
I tested the 'flood' version of Dr LED's recessed units, but found them to dim, and they have that blue/white harsh glare...the 'spot' version uses the 'warm' glow version LED's and the beam is more of a spot, but wide enough in a ceiling installation to provide a broad coverage at the couch level.
I'll post some pic's soon. Got the rear three mounted and they tested out great last night...I'm installing separate switches on the ceiling for each of the three 'areas' of lights.
I've also installed one of Dr LED's 'bulbs' into the outside Step light fixture. Previously I've converted all the rear tail/stop lights to LED units, and just finished replacing all the marker lights with LED units. I got my Dr LED units from West Marine...they have a good selection of LED stuff these days.
I haven't yet tackled the bedroom bunk lights, the two over the Kitchen sink, the round overhead light in the bathroom, or the two bathroom bulk head lights...those will be a challenge to change over, due to the amount of light output needed to be effective.
The Bunk reading lights can be done with new fixtures...but the other will be more challenging! Perhaps I can recess three 'spot' units to replace the large round original fixture that uses multiple bulbs...don't know yet.
Any successful conversions of these lights been down out in AS land?

Time machine...what a strange handle.......past that I'm glad you straightforwardly addressed this subject....many have saidthe like the product, yup, I do too, but they don't go on to say what they don't like about the product....namely price and light output. I will hold on, until someone says eureka. Thanks, Gerry
I did the full monte of my halogens to LEDs in my 19CCD......even went with red LEDs for the inner cabinet lights. They are the exact color temp (warm white) as the halogens and are about 75% (subjective evaluation) of the lumen output of the former halogens.
I like the reduced output, as I found the halogens to be very glaring. I am also getting a couple of 3 watt LED bulbs to test for reading light purposes.
On the plus side......I like the reduced output and the light 'color' is the same. I love the 'mood lighting' that the reds give me from behind the frosted doors of the upper cabinets......makes for a great nite light! And the best part....I can run my entire trailer on the amperage of just one 10 watt halogen.
On the negative..........COST.
I'll report back on the 3 watt model. I do have a 3 watt halogen flashlite, and it is superb! I'm expecting the same from the LED bulb.
BTW, I am now an authorized dealer for IMTRA Marine lighting products.

So, how much DOES it cost for each replacement "bulb?"
I have switched to the IMTRA Marine G4 base LED lights for my primary over head light in my main salon. I HIGHLY recommend the IMTRA Marine units for retrofit into any of the CCD lights. There is even a rear pin LED that perfectly fits the reading spots lights.
Thanks to forum member Lewster, the trailer now sips power while still allowing a LOT of lights to be on. The main overheads are a warm white, and are FAR superior in light output and color to the warm whites I bought from Yachtlights over a year ago.
I also added four cool white lights for the eating area and for the kitchen counter downlights. Pics and comparisons to follow.
