12V 150W Surface Mount Electronic Transformer for the GK LIGHTRAIL(R) Collection

Welcome to the new world of George Kovacs(R) lighting. GK LIGHTRAIL(R) systems represent a fresh approach to the concept of rail lighting systems. Our improved design offers all the options with a simple philosophy; make it easy. Let your imagination run wild as you invent new ways to light your home.

GK LIGHTRAIL(R) are low voltage systems that offers you a complete line of components allowing you to create a lighting plan for any room in your home. It consists of flexible rail, a wide array of fixtures and glass, and a variety of transformers that will adapt to all lighting needs. A complete line of accessories are offered to allow your vision to come to light.

Each surface mounted transformer includes a power feed for a standard 8' ceiling. If using a remote transformer, or if the ceiling is higher than the standard 8", you must use one of the adjustable power feeds. Add up the total number of fixtures and the length of the rail to determine what transformer would be best for your layout.

  • 12 Volts / 150 Watts
  • 5" Diameter
  • 5-1/4" Height
  • Includes power feed for a standard 8' ceiling

What is the difference between electronic and magnetic transformers?

  • Electronic transformers operate at a high frequency so they are smaller and lighter.
  • Magnetic transformers use a lower frequency, are heavier and can operate more efficiently on runs longer than 20' with minimal voltage drop.

What is voltage drop?

  • As the power is pushed along the rail each fixture takes its share of the power to operate the light. Therefore, fixtures farthest from the transformer receive less voltage. The fixtures at the end will not be as bright as those closer to the transformer. The magnetic transformer can sustain its full voltage on rail lengths up to 100 feet, Electronic transformers have a maximum voltage up to 20 feet.

What is a power feed?

  • The power feed is the piece that feeds power from the transformer to the rail.

Product Reviews

Rated 5 out of 5 by from It's bright again! Recently we up graded two lights fixtures to( 6 light 20W fixtures each and they were just super... bright + + +. Then just recently both units started to dull. Cleaned them but still very dim. So, ordered two new replacement 150w transformers and all is bright again. Easy to install in about 10 minutes. Just hope they last longer than the first ones.

Rated 5 out of 5 by from Better and less Expensive I purchased a solid state transformer to be used in a track light that is no longer made. This replacement is rated a twice the wattage of the original wire transformer and runs much cooler. Best of all it cost less than any other replacement I could find. Shipped fast and installed like a breeze.

Rated 5 out of 5 by from Best Company to Deal With I recently was given your website to place an order for a part replacement for my track lighting. Not only did I find the exact match, when I ordered the product it was in stock and shipped to me the next day. Your company exceeded my expectations as the confirmation shipping manifest indicated a 10 day delivery. To my surprise the product was received in 4 days. I would recommend your company for the complete product description and ease of doing business.
