I use the Trainmaster 1034 for lighting on the layout. Half are LEDs and half incandescent now. The MTH single engine house has some LEDs and I installed a few incandescent grain of wheat. I didn't know if I could install one of the GRJ modules and light strip ( on the AC connection ) for better lighting since I use the variable switch at different times on the 1034.

For fixed installations, my passenger car lighting module probably isn't the best choice. It's really purpose built for rolling stock. It also puts out a maximum of less than 50ma. Plenty for passenger cars, but for buildings, you may well want something more robust.
What would be a more robust solution John ?
Right now the 4 little wheat bulbs with the OEM lights improve the lighting somewhat. After removing the old passenger car bulbs and sockets, I though about repurposing them for the engine house . The LEDs long life was an attractive option.
I didn't have any idea if the variable on the 1034 would cause problems with the LEDs when I only used maybe half throttle at times .
I still am looking forward to getting more of the lighting kits for Judy's P.E. passenger cars. Only two more to go on the Pennsy Madison's.
For layout lighting, you can buy a cheap 12VDC power brick and use the lighting strips by the yard. Search for this on eBay and for $4 shipped you can have a 2A 12V power brick.
100-240V AC to DC Power Adapter Supply 12V 24V 5V 12V 1A 2A 3A 0.5A US/ EU Plug
Found this in my jumbled inventory .
Well, it's 15 volts. In order to use that and not over current the LED's, just stick about six diodes in series with the output, that will drop the voltage to around 12 volts. In truth, you can probably use the 15 volts as I have observed that with 12V, a full 5-meter 300 LED string at 15 volts still doesn't draw 2 amps, that's what you should be seeing if the current to each LED was 20ma.
Would that small brick work. How can you get the positive wire to connect to the light strip ?
PS. I know we discussed your non attachment to MIT.......but I saw your new photo on your post.........did you work on Hueys in Dong Ha in 1969 ?
You can buy a connector and wire to that.
You can also lop off the connector and just connect to the wires on the brick.

Nope, I was in the Navy from 1961-1966, I slipped away before the ugliness in Vietnam. 
I was lucky some how and made it back Thanks for your service to our country too John. I thought you looked like someone I knew without a terrific tan and a not so mature a countenance.
I'll have to jump on eBay now. Many thanks GRJ.
