Installation The SpectraLight Jr. comes ready to use with the exception of installing the glass diffuser. Installation is simple. Please follow the steps below to install a new SpectraLight Jr. viewing booth.

1. Move the viewing booth shipping container to the area where it will be used. Be sure to allow for sufficient room for assembly.

2. Carefully unpack and remove the viewing booth components from the shipping container. Look for the light booth and the glass diffuser inside the shipping container.

Note: Be sure to keep the shipping container in the event the booth must be returned for servicing.

3. Place the viewing booth on the table or desk where it will be used. Flip the booth over so that it is upside down. It is alright to rest the booth on the luminaire.

Note: The table or desk height should be determine by the average height of the observer and whether observations will be made from a standing or sitting position.

4. Remove the diffuser from the special packaging.

5. Insert the diffuser hinge pins into the front of the slotted receptacles located inside the booth on the underside of the luminaire. The bumpy side of the diffuser should face out to the interior of the booth.

6. Rotate the diffuser to its closed position and secure it in place with the latch.

Note: Ensure that the diffuser latch is secured before releasing. Failure to do so may result in the diffuser sliding out of position.

7. Plug the SpectraLight Jr. into a power source. The unit is automatically on once power is supplied to it. Notice that the UV light blinks every two seconds. This indicates that power is being supplied to the unit.

8. Installation is complete.

Certification Each SpectraLight Jr. is shipped from the factory with NIST Traceable Certification. Annual recertification by a GretagMacbeth Service Representative is recommended.


Operation Prior to operating the unit, please become familiar with the SpectraLight Jr. controls and front panel.

Controls and User Interface The SpectraLight Jr. front panel has five (lamp) on buttons and one (lamp) off button. Each (lamp) on button has a small green indicator light, which illuminates when the corresponding lamp is activated. Each lamp on button acts as a toggle switch for the lamp source. A single press of the lamp button toggles the lamp on and off.

All lamps are automatically turned off five minutes after the last lamp is activated. Therefore, if the unit is left idle lamps are turned off and lamp hours are saved. A cooling fan is automatically turned on when any lamp is activated. The fan will remain on for five minutes after the last lamp activation.

Figure 4. SpectraLight Jr. Front Panel

UV Button This button toggles on the ultraviolet source lamp. The UV lamp is the only lamp that may be used in combination with another lamp source.


The green light on the UV button will blink at different rates to indicate the status of the light booth:

Heart beat, once every two seconds: power is being supplied to the unit, and no lamps are active.

Rapid, twice per second: luminaire temperature has exceeded 70°C . For more information, refer to Troubleshooting on page 13.

Continuous green: the UV lamp is activated.

Continuous off: another lamp source is active or the unit is not connected to a power source.

DAY Button This button turns on the Daylight Lamp. Any lamp that was previously selected is automatically shut off.

F Button This button turns on the Fluorescent source. One of three possible sources will be used: CWF (Cool White Fluorescent), TL84 or U30.

A Button This button turns on the Incandescent Illuminant A source, 2856K.

HOR Button This button turns on the Horizon Daylight lamp, 2300K.

OFF Button Pressing the OFF button turns off all active lamps (including UV) and all front panel indicators. The UV indicator will have a two-second heartbeat to indicate that the unit is powered on and operational. The 'UV' indicator will stop blinking and assume normal operation if any of the front panel button is activated (including OFF).

To turn off the fan, press and hold the OFF button for three seconds.

Each lamp source button is a toggle switch for an on/off condition for the lamp. It is not necessary to press the OFF button to turn off a selected lamp source. For example, if the HOR lamp source is activated, pressing the HOR button again will turn the lamp source off.

Hour Meter The hour meter indicates the total time the Daylight Lamps are active. The hour meter will indicate that it is actively counting when the hourglass symbol on the display blinks. If the hour meter is not actively counting, the hourglass symbol will continuously remain on.

The hour meter should be reset to zero whenever the Daylight lamps are replaced. It can be reset to zero hours by simultaneously pressing and holding the ‘DAY’ and ‘OFF’ switches for three seconds.


Lamp Sequencing The SpectraLight Jr. is capable of performing a "Lamp Sequence"; a repeating series of chosen lamp activations in the succession. A lamp sequence is helpful if a hands-free visual assessment under multiple light sources is needed.

A lamp sequence will repeat for a five-minute period, after which all lamps are automatically turned off. Pressing the OFF button can also terminate the lamp sequence. Once the five minute sequence period is over, the same sequence may be re-programmed again.

To program a lamp sequence, proceed as follows:

1. Make sure the unit is powered on.

2. Press and hold for three seconds the source button for the first lamp in the sequence. Release the button.

3. Press and hold for three seconds the source button for the new lamp in the sequence. Release the button.

4. Repeat step 3 for any additional lamps in the sequence.

5. The sequence will start immediately. Each source in the sequence is turned on for four seconds each. The entire sequence will repeat for a five-minute period.

6. If UV is needed, it may be included by performing either of the following:

• After the sequence is programmed and has begun, press the UV button. The UV lamp will remain on for the entire duration of the sequence.

• After the first lamp is added to the sequence, press and hold the UV button for three seconds. The entire sequence will be performed with UV and then again without UV. The sequence will continue to alternate with and without UV until the five-minute sequence period is over.

Troubleshooting If the SpectraLight, Jr. is experiencing a problem, please consult the list of possible situations below to determine if the current situation matches one that is listed. If so, please attempt the possible solution. If the problem is still not resolved, please contact the nearest GretagMacbeth Service Representative.

Lamps/Indicators Unexpectedly Off OR the UV Indicator Is Blinking Rapidly Situation Description:

If the luminaire (upper chamber) of the SpectraLight Jr. reaches or exceeds 70°C (detected via an internal sensor), all lamps and corresponding indicators will turn off, and the fan will run continuously until the high temperature condition is relieved. While the high temperature condition is active, the 'UV' indicator will blink rapidly (approximately twice per second), and all front panel switches will be ignored.

Once the high temperature condition is relieved, the front panel switches will be honored and the 'UV' indicator will blink on once every two seconds until one of the front panel switches is activated. The fan will continue to run for an additional 5 minutes after the high temperature condition is relieved, and will resume normal operation if any of the lamps are turned on during that time.

What Should I Do?

• The unit will correct the over temperature situation as described above.

• Contact your local Service Representative.

UV Indicator Not Blinking (Slow or Fast), No Fan Activity Situation Description:

This situation indicates that no power is reaching the internal control circuit board.

What Should I Do?

• Check the power source. If the power source is alright, unplug the unit from the source for a minimum of 10 seconds and plug back in to reset.


UV Indicator Blinking Slowly, But Front Panel Switches Not Responding Situation Description:

This situation indicates that the circuit board has power and the processor is running, but is not operating properly.

What Should I Do?

• Disconnect the unit from the power source, wait 10 seconds, and then reconnect the unit.


• Test the front panel by pressing some of the lamp source buttons. If clicking can be heard while pressing the buttons, the unit is still operational. However, the lamps may require replacement.

• If no clicking is heard while pressing the buttons, the unit requires service.
