Interior lighting
Posted by Archived on February 21, 2014 at 8:28 pmJust finished replacing all of the interior lights on our coach with LEDS 4G bulbs. What a difference in power draw. The lights are as bright as the halogens that were in the coach.
I used the PWS (Pulse Width Mudulation) type bulbs that can be dimmed with the current Marathon system without issuses.
I found the bulbs on Ebay the price was $1.00 ea. for quantites of 100 or more. I used 50 and sold the other 50 to Red and Patty Lynch. Make sure to order extras so that if one messes up one does not have to wait for shipment to complete the job. The wait time to get the parts is 3-4 weeks.
See you all at Lazy Days Rally.

Hish,
How about a picture of the bulb.. I just ordered the disc type LED’s with extended pins to fit inside the fixtures.
-
Tom, aren’t the fixtures used by Liberty the ones that have the bulb inserted straight up rather than horizontal? If so, where did you find the disc style LEDs that will mount in those fixtures.
-
Please email me instructions of how to add pics in my response. The instruction on top is useless.

They make G4 LEDs with pins in up direction and side pins as well.
-
My 97 Liberty had the bulbs installed vertically, my 06 has the bulbs installed horizontally. Same bulbs, different orientation.
-
I’be seen G4 LED replacement bulbs that will work for either vertical or horizontal configurations. I haven’t seen the disc style for horizontal pins but not vertical. Can someone post a link. I’ve had a couple folks asked me for the same, but I didn’t find any, even the expensive ones.

Hish,
Look at the last forum topic, how to upload photo’s…

Tom, great info on a product that doesn’t appear available anywhere else. The problem many will face with the conventional G-4 replacement bulb is that the reflector in conventional fixtures are significantly blocked by these bulb replacements replacement. Most LEDs are highly directional, so they need to be aimed at were you need the light given they get little benifit from the fixture based reflector. That’s why I like the disc versions for the ceiling mounted halogen fixtures most of us have.
Until you provided this information I was recommending this one that has 7 LEDs that are downward directed. http://www.tmart.com/G4-27LED-5050-LED-Light-Bulb-Nightlight-with-Warm-Light-3000K-Highlight-12V_p183892.html?fixed_price=hk_intl&utm_source=base&utm_medium=organic&utm_term=88012318&utm_campaign=product&gclid=CPbf0YH-37wCFQ_l7AodjFAA7A

The ones I installed are fully dimmable for the full Marathon switch range. They are great and are as good as the halogens they replaced and cool to the touch. i emailed Tom some pics of the part and the installation.Tom is going to publish them for me I was unable to post them on the forum.

Hish ,
That’s been the problem with finding LED compatible with Marathon Tech Link system. Some have changed out bulbs and with-in a couple of weeks 50% failure due to dimming.
I have heard another story about leaving one only halogen to fool Tech Link.
Sooner or later there would be a solution found. Marathon was changing lighting systems out and reprograming Tech link with prices above $1000 dollars I’ve heard. Most of the expense being high priced LED’s.
At few dollars each this changes everything.

At $1.00 each I can chage them on weekly bases without every having to spend $2K they want for that job. I bpught few extras just in case that happens. I have had some of these bulbs installed for over two months without issues.
Tom
I tried mailing you the pictures but the system told me they file is too large.
I am going to try again on the site.
Bright picture, Part picture, Dim picture, I did not dim all the way down.

Looks just like the ones I have had in for over 2 years.. Don’t remember # but when I built coach I did 100% led. used some with prongs on back also.. Fwiw also liked so much I replaced all my landscape lites with them–sure stopped all that bulb changing.. Never understood the price converters were charging??? One point I found that in some cases for some unknown reason they were polarity sensative.. I don’t know elect that well but if you get one that don’t work check the fixture feed for plus -minus… Just what I learned from hands on. Bob
