This Installation Guide covers the following araya® Color Tuning Modules (CTM):
• CTM 012
• CTM 019
• CTM 032
For complete Color Tuning Module specifications, please visit: www.lumenetix.com/downloads
This Installation Guide covers heat sinking, case temperature measurement, secondary optics, power supply and wiring diagrams
for wireless operation using the Lumenetix Light Commissioning Tool, industry standard 0-10V wired controls or a hybrid
operation that combines hard wired and wireless control.
The CTM Source diffuser is fragile. Avoid touching the diffuser during
handling and assembly.
For long term, reliable operation, proper heat sinking is critical.
1 INTRODUCTION
2 HEATSINKING
The CTM light module requires an external heat sink in order to ensure proper operating temperature of the LEDs. The CTM
has a conductive aluminum case and an efficient thermal path to the LED array. These features promote efficient thermal
management and allow for a simple heat sink design in most applications.
Examples of heat sinking methods are: cast or extruded heat sinks, an aluminum panel or aluminum fixture housing. Both
carbon and stainless steel are much less efficient at transferring heat than aluminum and therefore are not recommended as
heat sink material. The heat sink mounting surface should be flat and smooth. Metal-to-metal contact surfaces will result in best
performance; anodized or unfinished mounting surfaces are recommended. Mounting the CTM on a painted aluminum surface
will reduce the performance of the heat sink material.
2.1 Compatible Heat Sinks
The following tables list heat sinks models that have compatible form factors and thermal resistance characteristics for use
with the CTM. The thermal resistances assume an approximate ambient temperature of 25C. The heat sinks listed here
are suggestions only. The heat sink must be evaluated and temperature tested in the fixture application at applicable
ambient temperatures.

2.2 Mechanical Attachment of the Heat Sink
The CTM light engine has two options for heat sink mounting:
1. Front mount using four 2-56 or M2 screws
2. Rear mount using three M3 screws
NOTE: CTM 019 shown, Drawing also applies to CTM 012 & CTM 032.
NOTE: SOME HOLES NOT SHOWN FOR CLARITY.
Figure 1: Front Mount of CTM to Heat Sink
Figure 2: Rear Mount of CTM to Heat Sink
The thermal management characteristics of the heat sink used with the CTM should be validated by measuring its case
temperature. This test should be done with the CTM installed in the fixture at ambient temperature and air flow conditions similar
to the end-use installation.
araya® CTMs are available with two ranges: 1600 – 4000K and 2700 – 6000K. The power draw of the CTM varies by approximately
one watt over the CCT range with peak power draw occurring at the CCT shown in the following table. Depending on the CCT
range, the case temperature should be measured at the following CCT setting.
CCT Setting for Case Temperature Measurement
CTM CCT range CCT Setting to Measure Tcase
1600 – 4000K 2800K
2700 – 6000K 3600K
The proper case temperature measurement location is next to the exit for the power leads, see Figure 3. The temperature reading
should be made after the unit has reached steady state, where the case temperature levels out. It is recommended to design for a
case temperature of 70° C at maximum ambient temperature conditions
The CTM color tuning module has built-in over-temperature protection. It is designed to turn down the current to the LED array
when the case temperature reaches 75° C. This ensures the LEDs don’t exceed their maximum rated temperature.
