Let's try again........

 

Cold cheap dome light LED's?  

I have been trying different ways of converting the coach interior lights to LED

The easiest way would be to buy some simple BA15 led bulbs but I believe cheap unregulated LED replacements are really not very reliable. If you have tried them you know they get very hot, and an even if it has not happened to me there are plenty reports of such bulbs "blowing" up. They will burn

I like those small SND LED panels.

But the problem with those are the very same thing, they to get way to hot and and will eventually burn also, but I found a easy way around that. 

 

By removing the 3m(?) double sided foam/tape the panels came with and instead gluing them with thermally conductive glue (heat sink plaster found on eBay) directly on to the aluminum panels of the original dome light they seem to be doing very well. The led panels now stays A LOT cooler as the aluminum part of the original lamp is acting as a heat sink. 

 

 

 

 

 

 

 

As you can see from the pictures I connected the 2pin connector from the LED panels directly in to some BA15 2 pin sockets instead of using the adaptors than normally comes with these panels. 

 

 

 

 

All in all this is a very cheap and quite simple modification that might even outperform those higher end LED replacements. 

I'm not saying this is the way you all should go, but this is how I got 15 very cheap good capacity "cold" warm white LED light drawing less than 3 amps all together at 13,4v in #477. And I feel I have tested this enough to make it wort sharing. 

 

Stay cool
