LED's in place!

Will post on the results after installation.
OK, so the LED's from the above website arrived two days ago. I forgot to take pics last night, but just returned from the Airstream with a mini-review. All in all, I'm really pleased with the change to LED, getting pretty much the same light without having to use (and listen to) the genset as often. Sue and I tend to boondock a lot, so that's a consideration. The following photos show the LED's in place. What I have NOT replaced as yet are the 5 halogen puck bulbs in the middle of the coach. Have to "pace" myself in purchasing the LED's. Each one cost ~$12 on average. I ordered "warm" light LED's for all but the reading lights (went with white light there). The only surprise I had was how much the light fixture LENSE cover for the dinette dimmed the LED. I've included the same view with the lense removed to show how much light is blocked by the lense cover. The bottom right photo shows just the two reading lights illuminating the dinette. The pic of three ceiling lights shows the halogen puck in the foreground, and the LED's over the bed area. Pretty close match in light produced IMO. The LED's over the dinette and in the shower cast a "colder" hue, which is OK, even though I ordered "warm", and the bulbs were labeled "warm". The website was prompt in its shipment, and the bulb prices were definitely competitive. Hope this answers some questions, but feel free to throw some more my way!

This same company has the Warm White in the same size as the Bright White Airstream carries. This Large Bright White seems to be popular because of the amount of light it puts out. They almost have the same part number.

Here it is at Airstream in Bright White.


Here it is at LED4RV in Warm White.


What is interesting is. They say that 9 out of 10 Women prefer Warm White over Bright White on their home page. I have let to find a woman that liked Bright White. I wonder if it is 10 out of 10????

Finally!

I finally found a source for the "elevator" bulbs used in the Tradewind couch and reading lights. These have a real long neck and were a pain to find. Better yet they are warmish. I have been using them for about a month now. Clearly, they do not put out near as much light as the old bulbs, but they do put out enough. The old ones really were a tad to bright for my taste.

In the overhead lights I have replaced 3 of the four bulbs with LEDs and left the fourth with a regular bulb. My thinking is I can turn on just the LEDs when boondocking or when I dont need really bright lighting and the fourth bulb when I do. One of the old style bulbs does put out a bunch of light. The light off these bulbs is cold though, which I am not crazy about. I will most likely look to replace them when the money flow is better.

Can you put dimmers on LED's?

yes you can dim leds but you have to use a PWM dimmer. if the led has a driver circuit (little circuit boaard with some black chips on it) then you won't be able to dimm it

A good PWM dimmer is the 7150, data shown here:

These LED lights from Superbrightleds use that 1.5A LED driver:

The interesting thing is that they are dimmable. The LEDs ignite at 5.6V and have the intensity of a night light at approximately 7.0-7.5V. Full intensity is reached at 9.6V and remains constant up to 16V. If the input voltage is increased beyond 16V, the LEDs dim slightly up to 40V (that may have been an artifact of the power supply).

The 7150 PWM driver says it's a constant current device. In this application it looks like it's constant current between 9.6 and 16V. I haven't done the experiment, but I think if you remove that chip resistor at the top of the component side (R820 and labeled R1) and replace it with a [remote] pot, you will have a nicely dimmable light. I'd actually replace it with a resistor (about 1.1 ohms, for a total current of 300 mA a minimum R) and a pot (maybe 15 ohms, which looks like that would result in 25mA total current at max R) so that you'd always have a minimum resistance for Rsense. The 7150 data sheet provides sufficient info to compute exactly what R value you need (it takes several clicks to get view or download the data sheet). Note the reference to 200m ohm below is milliohms, not megohms.

The power I used for this test was DC (I expect that's what you'll be using in an Airstream). You can see on the component side that 4 rectifiers in a bridge circuit allow this light to operate on AC or DC and the DC polarity doesn't matter.

Decided to bite the bullet and get some 1003 LED replacements for our last unconverted fixtures...after a review of this thread, I went with the 18 LED units from LED trailer lites...

LEDTrailerLights.com - RV LED interior ceiling light 1141 1156 1003 warm white

I used them in the three-bulb bath fixtures, and I'm very happy with the results -

The 'warm white' color is quite near the incandescent #1003 bulbs, and the output (without measuring) appears every bit as bright...

In the pic below, the 1003 bulbs are in the LH fixture and the LED's are in the RH side - you can see a slight color difference in the overhead end cap surface, but isn't really all that noticeable after the conversion...

May have missed it but here is another source for 1156 replacement LEDs:

Interior/ Porch LED lighting - Star Lights, Inc.

A bit more expensive but don't think I've seen any 1156 replacements with exactly this configuration. So if money is no object............

I've never ordered from these people and know nothing about them - picked this up from Casita Club.

I replaced all the incandescent interior lights with warm white LEDs from LED4RV.com. The 1156's work fine on the ceiling and overbed reading lights. I also bought some 1156 spotlights for the recessed lights over the sink and bathroom and for the 2 magnetic reading lights in the front lounge. For some reason one of my front lounge light fixtures won't light the LED. I tried multiple bulbs with no luck, yet the same LED bulbs work in the other light fixture?? I ended up leaving the incandescent bulbs in them. I'm happy with the light output and even more happy with the lack of heat being generated. It certainly will help the A/C keep the coach cool. It is amazing how much heat those incandescent bulbs generate.

I thought I had 3-1003 bulb light fixtures in the bathroom like Mexray and was surprised to find that they are standard base 40 watt light bulbs instead...although I'm assuming they are 12V and not 120V since they do work on battery power.

All-LED interior

Just installed the last group of LED's on the Bambi's interior, plus a great new LED porch light, all from Dan Brown at LED4RV.com. Dan is very prompt and provides great customer support! I strongly recommend this website if you're planning an LED retrofit.

Here's an updated link to LED Trailer Lights...

LEDTrailerLights.com - RV LED interior ceiling light 1141 1156 1003 warm white

They now have a 380 lumen LED bulb replacement unit, the other referenced units in thread above can also be accessed on this link...

I've had 10 of their 1141 replacement units (252 lumen) in service for several months and am quite happy with the bright warm light output...

Here's a new one I just got a few weeks ago:

11391F (flood style) for the little swivel lights:

RV-LED.com - 1139 Flood LED BA15s single contact base LED light

Now I can change the aim without burning my fingers!

Too Cool

Happened upon this blog... he's using self-adhesive LED light strips to convert a regular sconce light. And, in another one that he made one from scratch. Here's pics of the hightlights - and the blog at The Ultimate Roving Home
