Valoya’s BX180-2ch (LightDNA 2-Channel) is a dual-channel variant of the BX-Series bar for research growth chambers and rooms. It combines a daylight spectrum (NS1 or Solray-family options, spectrum-dependent) with a separately dimmable far‑red channel around 730 nm for replicating dawn/dusk conditions and adjusting red:far‑red ratios. The fixture draws 199 W and measures 1722 × 73.5 × 58 mm, weighing 3.9 kg. Two independent channels are dimmable via standard controls, enabling spectrum and intensity tuning. The luminaire is IP67 rated with passive cooling and a typical service lifetime of approximately 50,000 hours to L70. Certification covers CE and RoHS, and the BX platform is tested to UL/CSA standards. Intended for mid‑to‑high intensity applications requiring precise spectral control in controlled environments.
