300W 45×45mm High Thermal Conductivity COB LED for High Power Stage Lighting and Projector Spotlights
Product Overview
This 300W COB LED uses a large 45×45mm package and a high-thermal-conductivity copper-core ceramic substrate with vertical chip technology to deliver high luminous flux and uniform emission under high drive currents, specifically targeting stage, theatre, follow spot, projector and entertainment lighting applications.
Key Features
Depending on the application, high-CRI warm white (e.g. 3200K CRI>90), cool white or RGBW/RGBWA full-color options are available, meeting the color requirements of theatres, studios, weddings and concerts.
The 45×45mm substrate ensures mechanical strength and contact area for cooling, while the small light-emitting surface produces high luminance and excellent optical control, ideal for reflectors and zoom optics in narrow-beam, high-intensity stage spots.
The high-thermal copper-core ceramic or metal substrate package provides low thermal resistance, efficiently transferring heat to the heatsink, reducing junction temperature and enabling high-current operation, which is essential for 300W stage and projector luminaires.

Frequently Asked Questions
Q: Why is high thermal conductivity packaging critical for a 300W COB LED?
A: A 300W COB integrates many chips and generates substantial heat; a copper-core ceramic or metal substrate with low thermal resistance quickly moves that heat to the heatsink, preventing excessive junction temperatures that cause lumen depreciation, color shift and shortened lifetime—critical for high-duty stage fixtures.
Q: What lifetime can be expected from this type of 300W COB in stage fixtures?
A: Under proper thermal management and drive conditions, similar 300W COB stage sources are typically rated for about 50,000 hours.
Q: Can CCT, CRI or multi-color (e.g. RGBW) versions be customized?
A: Yes. Many 300W stage COB platforms support multiple CCTs (e.g. 3200K, 5600K), high-CRI versions (CRI>90) and RGBW/RGBWA multi-color options, which can be tailored to the application and control protocol; it is best to specify color and control needs at the project start.
