Our new CK871 Ultimate Flickering Fireplace Unit has been designed to provide the most realistic flickering fire effects available anywhere. Its features create a natural, true-to-life fireplace flicker and not the usual on/off operation. In other words, no more flashing, just a gentle realistic flicker to put warmth and glow into your fireplace and lights.

The unit comes with four bulbs; three flicker and one constant. Each flicker bulb is controlled by a separate electronic circuit, thus creating its own independent flash rate. The supplied bulbs can be installed either in the supplied coal insert or used separately in an existing fireplace.

• The included bulbs are oversize to provide the maximum possible light output and are attached with screws for easy removal and replacement; Not soldered in place.
  
• Operates from dollhouse power (either 12VAC or 12VDC) and is guaranteed not to flicker other dollhouse lights.
  
• Small circuit board size (1W X 1 3/4L X 3/4H) allows easy concealment.
  
• Complete installation and operation instructions are included with each package.
  
• The CK871 can also be used to create a flickering Christmas tree. Simply use CK1020-1 or CK1020-2 Xmas strings in lieu of the supplied bulbs for a dramatic Christmas tree display.
  
• Replaceable light bulbs available CK1010-33A or CK1010-33B.

For hundreds of years, lighthouses have served as beacons in the night for both navigators and those lost at sea.  Countless ships and lives were saved thanks to their warning light.  Some, equipped with powerful Fresnel lenses, were visible as far as 25 miles out to sea.  But, with new methods of navigation, many lighthouses have become obsolete and no longer act as lighted sentinels along dangerous shores.

However, the love of this nostalgic era has not vanished.  Today, the popularity of lighthouse collectibles and memorabilia is making this one of the fastest growing hobbies in America. Everything imaginable from "to scale" lighthouse models to monogrammed wearing apparel is now in style.

Until now, a realistic beacon light for the various scales of lighthouse models being manufactured was not available.  Some large-scale lighthouses incorporated motors and gearbox assemblies to actually rotate a light, but these were both expensive and cumbersome.  In addition, this method was not feasible for small-scale structures.

A means was necessary whereby a realistic beacon could be incorporated into lighthouse models of different sizes.  The three lighthouse beacon lighting kits developed by GRS Micro Liting can now provide this ability.

The electronics incorporated into each provides a completely realistic "rotating beam" effect without moving parts or mechanical assemblies.  To simulate this rotating effect, the intensity of the lamp is rapidly ramped up to full brightness and then dimmed gradually, to give the illusion of a rotating beacon.

Many lighthouse models do have permanent on, or flasher-type bulbs, but these do not accurately simulate an actual working lighthouse.  The GRS kits use basically the same electronics, only the bulb size is changed to create the three different scales offered.
