What makes Chip Scale Package LEDs the definitive choice for professional fixture designers who demand compact form factors without compromising on optical performance.
Industry-leading small size enables dense multi-color arrays with minimal LES — tighter beam angles and higher throw distance for film & stage fixtures.
Up to 25W per chip in 4.0×4.1mm package. Exceptional watts-per-square-mm — maximize output within constrained fixture geometries.
11 color options from 450nm Royal Blue to 7500K Cool White — including PC-Lime and PC-Amber phosphor-converted chips for CRI optimization.
Tiny footprint allows custom module dimensions for different light fixtures. Design the LED board to fit the optical path — not the other way around.
Small Light Emitting Surface enables tighter collimation, narrower beam angles, and superior center-to-edge uniformity in spot/flood configurations.
Direct solderable CSP chips simplify PCB layout. Mix colors on a single MCPCB without wire bonds — reduced assembly cost and improved thermal path.
CSP LEDs power the most demanding multi-color lighting applications where size constraints and optical performance are both critical.
Compact CSP arrays enable slim-profile RGBLAC panels and Fresnels with cinema-grade color accuracy and high CRI.
High-density multi-color engines for soft panels, ring lights, and key lights with smooth CCT tuning and full-gamut output.
Tiny LES enables tight beam moving heads and wash lights — high output from compact optics for touring rigs.
Custom wavelength selection for endoscopy illumination, surgical lights, and fluorescence excitation with precise spectral control.
Ultra-compact form factor fits adaptive headlight modules, ambient interior lighting, and external signature lighting.
Precise wavelength targeting — 620nm red for chlorophyll A, 450nm blue for vegetative growth, custom spectral recipes.
