Spare Parts

It is not always necessary to send the Geochron back to the factory, since there are certain components that can be easily replaced by the Geochron owner.

Replacement Bulbs

LED Bulbs only work in Kilburg and Boardroom Geochrons that are newer than 06/2015, OR have been upgraded to the LED Lighting System. They are custom fabricated for Geochron, and only available here. Quantity is one bulb, not a pair. Order two if you need a pair.

To determine which bulb replacement matches your Geochron, you’ll need to find the sticker on your Geochron’s light track.

Remove the light track from the bottom of the clock to remove the bulbs. Based on the sticker, choose the correct bulb replacement below:

Legacy Fluorescent Bulbs, 1964-2016Note: Used in clocks from 1964-2016. Ballast may need replacement, but the bulb is widely available at local home improvement stores. To update your light tracks to LED, follow this link.

Shipping is included in the USA. If overseas, please call us.

General note: If both bulbs are not functioning along with other moving parts of the clock, or if the bulbs are flickering, flashing, or abnormally dimming, new bulbs may not correct the issue. Please call us to troubleshoot.

If your clock was built before 06/2015, LED bulbs are not compatible. You’ll need to send us just your light tracks, and we can convert them to work with LEDs. All rebuilds will include the LED Lighting System. They look brighter, more colorful, use 60% less energy, and last three times as long. Learn more about updating your light tracks to LEDs.

Mounting Kits

Surface Mount Bracket Kit 

A special mounting bracket is required in order to mount the Geochron. Although they are included with every new clock, often these brackets are lost in a move or not included when someone receives them from a relative or friend.

Flush Mount Bracket Kit

Flush mounting the Geochron requires special “flush mount brackets” and a recess in the wall. They are not included with the Geochron by default. The flush mount brackets enable you to swing the Geochron out of the recess to be able to access the setting knobs and electrical cord.

Legacy Lighting System

Fluorescent Magnetic Ballast Upgrade

On July 2010, the Geochron (North American units) light fixtures were upgraded from magnetic to electronic ballasts. The benefits from this change are:

  • longer lasting ballasts
  • use less power

The entire light fixtures for instance can be upgraded by just sending in the fixtures themselves. The process costs $90.00. All shipping costs are based on the distance from the factory and the method of shipping. To order please call 1-800-342-1661 or contact us.
