The Technology Inside

The One Family

The Feature Set

The CTM1C family combines driver electronics, logic and communications in a Zhaga compliant 50mm diameter package.

The CTM 1C family has a range of 1650 -8000K at a CRI of >90* and <2 SDCM over life. 0-10V, Bluetooth and DMX are on board. *From 2000–6000K.

A highly engineered silicone diffuser.

Light from the five color array is diffused at efficiencies up to 92%.

A non-yellowing plastic housing with Zhaga-compliant heat sink mounting holes.

The housing enables light emitting surfaces of 9, 12 and 19mm and multiple reflector attachments.

The highly engineered mixing chamber is designed to efficiently mix light from the 5 different colors of LEDs.

The high reflectivity and engineered design facilitate near field mixing of multi colored light.

The logic board contains the electronics that are the processing and communication brains.

The logic board manages the color model and Bluetooth communications.

The LED and Driver board contain the driver electronics, five color LED array and a highly effective platform for thermal pathways.

The CTM 1C family delivers up to 2000 lumens and dissipates up to 35W from a 50mm base.

The CTM1C Platform

CTM1C round LED light engines mix five colors of LEDs across a tunable color range of 1650–8000 K or a warm dim range of 1800–3050 K. The light can be dimmed from 100–1%. The round LED light engines deliver up to 2000 lm of light at 90+ CRI. Proprietary thermal and optical technologies ensure color consistency of < 2 SDCM over the 50,000-hour rated life.

CTM1C simplifies fixture control integration and reduces cost by packaging Bluetooth LE (for commissioning), 0–10 V and DMX512-A-RDM on board the light engines. Lutron® EcoSystem or DALI Type 8 compatibility is achieved by using the ERP Digital Control Adapter. DALI Type 8 can also be packaged on board the round LED light engines. Legrand® Wattstopper® DLM compatibility is achieved via an external adapter.

The CTM1C-E Platform

The ‘Entertainment’ family of araya Color Tuning Modules (CTM1C-E) delivers tunable white light across a CCT range of 1700–8000 K and dimming from 100–1%, while maintaining constant CCT, 90+ CRI and 70+ R9. With an expanded color gamut and on-board thermal feedback for color consistency, this family of CTM lights provides exemplary performance for applications requiring high quality in color.

Notable features of CTM1C-E are on-board DMX512-A-RDM, over-the-wire FW upgrade-ability (FWU), and preloaded RGBW personalties. Within this family of CTM lights, you can choose from any one of 15 personalities, which include the original arayaTM Color Tuning (HSI), Warm/Dynamic Dimming, and several RGBW control options.
