GC2104E & GC2105E: Ultra-Thin Architectural Recessed LED Downlight System
H30mm Low Profile | Round vs Square | Single vs Double Head

The GC Series introduces the ultimate shallow ceiling solution for modern interiors. By combining an ultra-thin H30mm low-profile structure with high-efficiency diffused LED technology, this comprehensive downlight family allows engineers, distributors, and designers to achieve perfect layout consistency across three distinctive product profiles:
-
GC2104E Series (Circular Minimalism): A collection of classic Round Recessed Panel Lights spanning from a compact 3W to a powerful 24W. Ideal for fluid, ambient transitions in corridors, living spaces, and hospitality lounges.
-
GC2105E Series (Geometric Single Head): Sleek, sharp Square Recessed Downlights that align perfectly with modern grid ceilings, minimalist architectural lines, and contemporary retail store aesthetics.
-
GC2105E D Series (Twin Linear Cluster): A high-performance Square Double Head Linear Grille Downlight configuration. It packs two independent light engines into a single rectangular frame (5W+5W up to 15W+15W), doubling the lumen delivery from a single consolidated plasterboard cutout.

FAQ
Q: Why is sourcing a uniform series like GC2104E and GC2105E advantageous for real estate projects?
-
A: Procuring mismatched lighting families from different factories causes deviations in color rendering index (CRI) and color temperature (CCT) shifts across rooms. As demonstrated in our universal engineering grid, the GC System utilizes identical driver dynamics and LED binning standards across all styles (round, square, linear twin). This guarantees 100% aesthetic harmony from the smallest guest restroom (3W) to the main lobby hall (24W or 15W+15W linear models).
Q: Can this series be custom-built with different dimming interfaces like DALI-2 or 0-10V?
-
A: Yes, absolutely. We are a project-focused B2B manufacturing supplier. We can bundle the GC series with high-quality, external constant-current drivers that match your automated smart building frameworks—including TRIAC phase-cut dimming, 0-10V analog setups, or digital DALI-2 networks.
Q: Do you offer bulk discounts or custom bezel finishes for hospitality projects?
- A: Absolutely. As an OEM/ODM lighting manufacturer, we support project lighting consultants, shopfitters, and B2B distributors with competitive bulk pricing, Dialux simulation, and customized finish options (e.g., black trim or gold reflectors).
