Good day fellow hobbyist,

I have started working on the lighting circuit for my small layout.

I decided to go with a 12V DC supply with dimmer and use of LED's. I believe is the most cost effective solution and safe as you don’t end up installing buring hot lamps in small plastic enclosures... Regarding LED I found below websites really handy:

General about LED:
http://www.kpsec.freeuk.com/components/led.htm#colours

Tinting of LED:
http://www.ngineering.com/led_coloring.htm

With inspiration from another user here (http://www.marklin-users.net/fo...st16932_Jornebanen.aspxk) – thank you JorgenBigGrin - I also constructed my own platform lights. Cost me about 1.5 USD a piece.

The lights are made up of 3mm warm light LED, 460 ohm resistor and brass tubes from K&S engineering:

I used the brass tube tube itself as a conductor. Used an automobile grey coloured primer spray can, which gave a really nice finish.

The hood is made from dome studs (clothing accessories found on Ebay). Hardest part was to drill the hole in the top...

And most importantly it was lots of fun to make it yourself!

Danlake:

Great post. The lights look great. Did you taper the tubing at the end where the light fixture attaches or does it just look like that?

Hi Chris,

Thanks - the 2 pins from the LED is used to secure to the brass tube. The minus is soldered to the brass tube itself and the plus is soldered onto the cable which you can see just penetrating from the open end of the tube. The black part above the hood is just the top part of the actual LED painted black.

Very nice design.

I also made my own lights and found the project to be rather satisfying.

A sample of my designs can be seen at the following site.

Thanks for comments.

I was hoping to make some other versions (for street lights) where the top is bended 180 degress (u-shape), but keep getting sharp kinks in the tube. I was wondering if anyone had some good techniqiue to bend the tubes smoothly (maybe by heating them)?

Enjoyed browsing trough your website Matthew. Nice layout you build.

Thank you, it was a real joy to build and play with.

To bend the 3mm tubing to a virtual U-shape, I created a simple jig. Wasn't a perfect U-shape, but created the shape I was looking for.

Here is a few pictures of the jig I created.

Jig parts with a sample bent tubing.

Tubing is inserted until it reaches the screw.

Hope this gives some ideas for trying to create your U-shaped lamp posts.
