LED Lamp Source

Great thread. I'm also relamping my A/S, a BMW motorcycle, and my house (12VDC backup lighting) and thought this source might be helpful. Good prices and products.

Hey thanks Westfalia, I noticed that I had a broken glass lens on one of my lights in the overhead comparment above the sink. I contacted ITC and they were very helpful in sending me out a replacement and a few spares. I had them in 4 days to Canada. Cost was $3.00 each plus shipping via UPS. Lighting dealer up here wanted $36.00 each! Great company to deal with.

Canuks, Good to hear it! I might have to do the same thing for one of my lights soon.

Update on the LEDs. So far I am liking them, but I need MORE of them. I will be keeping them in the upper front cabinet. They put out a pleasant, if not slightly dim, light. We use them almost exclusively when dry camping which has been 100% of the time. The battery savings appears to be very noticeable.

The hazard orange reflection from the cabinets is noticeably muted due to the wavelength of the light. However, once the cabinets are loaded with gear most of the orange is not visible anyway.

LED Replacement for Halogen Cabin Lights

What do you think about this g4 based LED array.

Certainly looks powerful enough.

Do you think it would fin in the lamp?

Hi,

You can buy these bulbs on e-bay for about $!.50 each including shipping, less than $1 if you buy 30.

I'm not trying to convert to LED's, just looking for a less expensive source for the existing Halogens. Anyone find them for a good price? I just burned out the THIRD one since I got my CCD in March

So today, I was thinking of ordering more LED lights. Lo and behind, a new LED light is available with a G4 pin base. It looks promising, and possibly brighter.



This one is thicker, so the reflector housing may need to be removed.

Has anyone else tried the LED lights in their CCD lights? It's been a little under a year since I bought mine, and I have enjoyed them, especially when boondocking. I can easily leave them on all night with no worries on battery consumption. In their currently installed position, they leave a pleasant light that is more than bright enough once your eyes have adjusted. They are painfully bright if you turn them on in the middle of the night.

I tried them too

Hi Westfalia,

I too have purchased led lights, in fact I have purchased two of the type you showed in your post. I purchased them about a year ago from a company in England, they were a cluster of (I believe) 9 or 12 bulbs, I'm away from my trailer so I can't tell.....the supplier claimed they put out the equivalent of 10 halogen watts, but they do 1/2 that (at best). I asked him multiple times for lumens output and he never responded. Also, they put out a slightly greenish hew. When I tried to post my comments on his web site he repeatedly deleted them; they were not ugly, just what I experienced as above. They are about $12 each as I recall. He threatened to sue me if I did not quit posting what he believed to be negative comments on his product. One other thing, it appears two of the led's in the cluster have become intermittant, flashing on and off. Are you sourcing these bulbs from England? I can't recall the exact company, when I get home in a week I'll tell who I purchased them from. Thanks for the post. One other thing, I replaced all of my 10 watt bulbs with 5 watt ones at a cost of about 80 cents each, hardly any significant loss of light.

Maybe I can help

To All,

Just came across this thread and I may be able to shed some light on changing over the halogens in the AS models. I have a Safari SE model which uses the same lamps as the CCD.

First off, I am not a vendor, I am just a guy with a bit of experience in the manufacture of LED based lamp systems. I have been involved in the development of both the LED light source as well as application engineering for industry wide adoption of LEDs. The field is evolving very fast and new products are available all the time.

As per the last couple of posts, many suppliers claim certain performance standards which one finds to be "NOT" once you receive the lamp. Most of this is due to the manufacturer not understanding the physics behind an LED or the optical system necessary to direct the light in a functional manner.

Most of us are aware of LEDs in many consumer products, most are small applications where the light projection is minimal. Most of these lamps are rated in MilliAmps or fractions of an Amp. Newer LED light sources are now multi AMP, most common being one to five Amp. The challenge now is to harness the light and direct in a useable lamp. The cluster type lamps in the previous posts can not provide the light you need in the AS housing. The higher Amp LEDs are needed to do the job.

I will check with the more progressive manufacturers and see if there has been any designs that could be utilized in our AS applications. The fact that we have a 12 volt system is a plus since most LED lamps can be made to operate on vari-voltage of 4.5 volts to 18 volts. That means that as our batteries wear down, the LED lamps will maintain the same brightness over the full range, no dimming. Most likely a different optic (lens) will be required to match the LED to get the best performance. For your energy calcs, these type lamps will probably be rated at about 2 to 3 watts at 12 volts, so you can easily see a benefit. A big plus will be much less heat which will reduce your AC or fan costs.

I will check into this after the holiday and report back any info. Since I want some for myself, I am a bit motivated.

Hope this helps a bit.

John

Timemachine, thanks for your information. Do enjoy the low light of my current LED. The are dim and efficient, both being good when boondocking, and work well in their role in the overhead cabinets. However, they truly are too dim for any kind of task lighting whatsoever. I look forward to hearing what products you might be able to come up with to solve this. The lens in the current housing definitely diffuse and scatter what little my LEDs do produce. I could see a plastic lens being made that could replace the glass lens.

Keep the thoughts coming! I'd really want to replace more lights with LEDs in the near future. I'm also thinking of adding foot level path lighting to make midnight bathroom runs a bit more bearable.

Westfalia,

I will be working on the overheads...I am pretty sure that we can find or make some LED lamps that we can retrofit into our AS that you can actually use as a task light.

As for path lighting, I worked on past programs for cruise ships and aircraft for exit lighting on or near the floor with great illumination, I will bet the same products would work for your project....I will dig up the appropriate info. There are also some slick walkway lights that were developed for theaters that were mounted to an adjacent wall or seat to light the floor, those might be more reasonable in regards to cost and a little easier to install. I check into it.

John

Halogen Bulb retrofits with LED's on CCD trailers

This is the path for the G4 based led arrays that will fit into the G4 bases of the 10 watt halogen fixtures as found on Airstream CCD trailers (as well as others). The reflector does not need to be removed in the halogen light, simply remove the halogen bulb and insert this LED array.
http://www.ultraleds.co.uk/default.p...87684d8d5469a5

I have found these led arrays to put out (roughly) 40 to 50% of the "lumens" of a 10 watt halogen, and of the two I purchased for trial, one array has a couple of led's that are flashing intermittently.

I'd say I am 75% satisfied with the results given the cost and the light output.

Cool G4 21 Led Lights

OK,

I got the 21 LED assembly. There things are great! and are really bright! So much so you could even use them for task lighting. I have them in both the overhead storage compartments in front. Both have 3 light sockets. So I have a total of 6. With all 6 lights turned on the entire front part of the trailer is illuminated.
