COB LED Chip Bulbs High Brightness DIY Electronics

High Power COB LED Chip Bulbs are compact, high-brightness LED modules designed for DIY electronics projects. They’re ideal for hobbyists, makers, and engineers who want reliable, multi-color lighting in a small, easy-to-integrate package.

Color options for versatile projects: Blue (440–445 nm), Red (625–630 nm), Yellow (590–595 nm), Green, and White. White is available in warm (3000K), neutral (6000K), and cool (7000K) variants to match different design aesthetics.
Three power levels to fit your setup: 1W at approximately 350 mA, 3W at approximately 700 mA, and 5W at approximately 750 mA, allowing you to balance brightness with your driver capabilities.
Color-specific forward voltages: Blue/Green/White ≈ 3.2–3.4 V; Red ≈ 2.2–2.4 V; Yellow ≈ 3.2–3.4 V. Choose the variant that matches your supply and circuit design.
Brightness varies by color and power: White variants typically deliver 280–320 lm, while Red and Yellow variants are in the 130–160 lm range, helping you plan lighting levels for indicators, accents, or displays.
Easy integration and reliable performance: Built with a COB (chip-on-board) approach for consistent emission and straightforward mounting in DIY builds, prototypes, and educational kits.
