News Release: Learnew Opto Unveils 3838 Bi-Color COB LED Chip for Professional Photography Lighting

Learnew Opto, a leading manufacturer of high-power COB LED, has officially launched its new 3838 bi-color COB series customized for studio photography and live broadcast fill lights, bringing a brand-new high-efficiency lighting solution to the photo lighting industry.

The core product integrates 200W warm white and 200W cool white chips on a single substrate with dual independent circuits. Working under 2.8A driving current and 72–76V voltage, it reaches luminous efficiency of 80–100LM/W and top-tier CRI95 color rendering index. Its high-density chip arrangement delivers uniform, spot-free soft light, perfectly restoring real texture and color for portrait shooting, commercial product photography and live streaming.

Different from single-color COBs, this bi-color design supports stepless color temperature adjustment, greatly lowering the structural R&D cost of lighting fixtures. Featuring high power, high density and high efficiency, the chip balances strong brightness and low energy consumption. Stable electrical parameters guarantee long service life and consistent light output.

Learnew Opto provides customizable power, color temperature and size solutions. The new 3838 COB has drawn wide attention from lighting manufacturers, becoming a cost-effective core component for mid-to-high-end photographic lights.
