Removing/shielding RF noise from 12V Fluros

Thanks for the reply.

They are the fixed fitting sort and I have used a 12V workshop fluro around the vehicle without any interferance.

Whatever it is, is just a bitch.

I am going to try a television next to see if they interfere with that.

Thanks for the the feedback.

It's obvious that you have experienced the same problem and your 'fix' is interesting to say the least.

Good old Aussie lateral/inventive thinking at its best.

I still believe the real answer lies with the Electrical Engineering R&D 'Einsteins'.

Funny thing about this whole thread is that you and I seem to be the only ones in the whole of Australia experiencing this phenomenon.

Makes you wonder what all the others use for 'lighting sources'.

Eric, very interested in your comment about LED lighting, was thinking of using this instead of fluro's, but have not checked it out further. Any information on types etc gratefully recieved.

Eric

Mate it looks like there are more than two of us who are game enough to 'fess up' to having this problem.

I two would be interested in your idea/s on LED lighting.

Thank you for taking the time to reply.

If you have continued to watch this thread you will have no doubt by now seen that I am not a lone ranger here. Thought I was for awhile though.

Anyway, I checked out JAYCAR on the NET an found that they sell a different interior fluro to the ones I have.

So I will check it on Monday and use the information supplied by others on the forum to see if it has one or two diodes.

If I can't fix it that way then I'll try some of the other recommendations except for the petrol lamp as I am a Diesel freak.

Thanks for the info.

I get the gist of what you are saying, however I am not sure I really understand what a Toroid fix is, and if I did, how I would actually go about it.

In the short term I am going to try and source another brand/type of fluro and see if I can cure it that way.

Good to see another who has experienced this problem.

By the way, the petrol lamp do-da is out as I am a pure diesel man with a touch of LPG to cook with.

I am with you on this.

In the event that I can't source a fluro with two diodes or one that makes no RF interferance, do you know if an Electronics Tech or a Electrical engineer can modify the ones I have, by adding the additional diode etc.

Ken.
The cct uses two transistors not diodes, the problem is on my list of things to fix, I have a cct and some of the hardware built for a interferance free lamp. In the interem I am using a light that is made from 4 off 5mm ultra bright white LEDs purchased from Jaycar for $15 total, the 4 are simply connected in series on 12 volts if you are running you motor while the light is on there is a risk of damage to the LEDs but if the motor is off the voltage is just right without any resistor. The alternative energy asscosiation based in melbourne are selling 1 watt white Led that is as bright as a 20 watt flouro but I think they are not legal because they exceed the allowable radiation under the laser safety regulations. If the LED was used in conjunction with a difuser to spread the beam they may be ok but I hesitate to recomend them if you have children. The !watt LED cost about $50. Eric.

There you go Haze, you learn something every day, well I do anyway.

With a bit of luck and all the free and open advice that has been provided by contributors to this forum I/we might be able to solve this vexing problem.

I intend keeping at it until I can get battery powered lighting that is RF free (noiseless).

If and when I do I'll chuck a post on and let you all know.

You wouldn't think it could be that hard to fix. (maybe it is )

Mate, you may have come up with a winner here. Thanks for the info.

I just had a look at the ATA website and noticed that they are in Melbourne where I am.

Soooooooooo! tomorrow I'll give them a call and possibly go and have a look.

I'll keep you posted as to how things pan out

I've actually got a swivel mounted halogen in the camper as a reading light and know what you are referring to.

We also cook outside when the weather permits.

Now our Troopy camper has a pop-top with the main bed 'upstairs when its made up. When the top is popped its a fairly large area to illuminate.

Sooooooooooo, the good old conversion man installed three of these bastard fluro's.

This week, I will research/make enquires re the LED'S mentioned above in this thread and have a chat to JAYCAR about alternative ones which don't make noise as well as enquire about RF Chokes with them as well.

Once I get some believable answers I will post same on the forum.
