The CCT Changeable AT04 LED Downlight is a recessed lighting fixture offering selectable colour temperatures of 3000 K, 4000 K and 6500 K. It is available in six discrete power ratings - 5 W, 7 W, 9 W, 12 W, 16 W and 25 W - each delivering a luminous efficacy of 100 lm/W. All versions operate on a 220 V, 50 Hz supply, present a power factor of 0.5 and meet CE and KC certification requirements. The units are rated for a lifespan of 30 000 hours, provide a CRI of 80 and are guaranteed flicker‑free for visual comfort.

The housing is formed from extruded aluminium alloy, a material commonly used for its thermal conductivity and durability. Typical recessed downlights of this class use a 120° beam angle and a standard cut‑out diameter of 76 mm, which matches the AT04 design. The fixture carries an IP20 rating, suitable for indoor ceiling installations where moisture exposure is limited. Standard industry practice also includes a heat‑sink fin arrangement to maintain junction temperature within acceptable limits.

The AT04 is suited to offices, hotels and retail spaces where flexible colour temperature selection aids lighting design.
