Dimming interface: DALI-2 DT6/DT8.
T-PWM™dimming technology allows continuous and flicker-free images
under high-speed photography.
With soft-on and fade-in dimming function, enhancing your visual comfort.
Dimming from 0~100%, down to 0.1%.
Adopt constant power design that can adjust different color temperature while
brightness remains the same.
Comply with the EU’s ErP Directive, standby power consumption < 0.5W.
DALI bus standard IEC62386-101, 102, 209.
Innovative thermal management technology intelligently protects the life of
the LED driver.
Overheat, over voltage , overload, short circuit protection and automatic recovery.
Suitable for ClassⅠ/Ⅱ/Ⅲ indoor light fixtures.

• On/off control: Short press.
• Stepless DIM/CT: Long press.
• With every other long press, the light level goes to the opposite direction.
• Dimming memory: Brightness will be the same as previously adjusted when turning off and on again.
DIM: 0-100% brightness adjustment.
CCT: 2700-6500K Color Temperature adjustment.
Short press to on/off, long press to dim.
In the case of DC voltage input, PUSH dimming is invalid.

≥15cm ≥15cm
Please do not stack the products. The distance between two products should be≥15cm so as not
to affect heat dissipation and the lifespan of the products.
Please not place the products on LED drivers. The distance between the product and the driver
should be ≥15cm so as not to affect heat dissipation and shorten the lifespan of the products.

Warranty exclusions below:
Warranty periods from the date of delivery 5 years.
Free repair or replacement services for quality problems are provided within warranty periods.
Beyond warranty periods.
Any artificial damage caused by high voltage, overload, or improper operations.
