The Lamplighter™ box provides 250 times more light to a fiber than a typical 20mA LED can deliver. On a layout, a single fiber provides as much light as a single LED, but without any wiring. Now that's a benefit.
Although to date all of our experience has been with only HO scale, we believe we are now positioned to enter the N-Gauge market and will have suitable lighting products on our product list in the very near future.
With a modular unit like this, I could now plan to light up the whole train layout. A huge advantage is that one region could now be lit up with only one LED bulb and fiber optic cabling. One of the greatest benefits of this approach is the ability to light up buildings in seconds!
