Have you heard about COB LED grow lights? If not, you’re in for a treat. In this article, we’ll explore the phenomenon of COB LEDs and why they’re rapidly revolutionizing indoor grow light technology.
What is a COB LED?
COB stands for Chip-on-Board, which is an LED packaging technology that mounts multiple LED chips onto a substrate to form a single module. These minuscule LED chips are wired and packaged together on a single ceramic or copper board, giving the appearance of a lighting panel when energized.
Advantages of COB LED Grow Lights
COB LED grow lights offer numerous advantages over traditional HID bulbs. While HID bulbs still have their applications, the benefits of COB LEDs outweigh the drawbacks. Let’s delve into why COB LEDs are worth considering:
Improved Electrical Efficiency
When it comes to grow lights, efficiency is crucial. COB LEDs excel in this aspect, producing a higher amount of photosynthetically active photons per watt consumed at the wall. This translates to better growth for your plants.
Improved Lifespan
High-quality LEDs, such as COB LEDs, have an exceptionally long lifespan. With a predicted lifetime of 50,000 hours, a quality LED fixture will last for years. This initial investment pays off in the long run as you save on replacement costs.
Improved Spectrum
COB LEDs offer a broad and targeted PAR spectrum, providing optimal light for your plants’ growth. The spectrum they emit closely resembles sunlight, ensuring your plants receive the right wavelengths for photosynthesis.
Improved Light Quality
COB LEDs boast a high Color Rendering Index (CRI), meaning they accurately render colors. Unlike other grow lights that may distort colors, COB LEDs provide natural and vibrant lighting for your indoor garden.
Allows Replacement of HID Bulbs
COB LEDs are more efficient at producing photons than HID technology. This means that, at the same power consumption, COB LEDs outperform HID bulbs in terms of light intensity and quality.
Better Light Distribution
COB LEDs can be spaced for better uniformity, preventing hotspots or low-intensity areas in your grow room. By strategically positioning multiple COB LEDs, you can achieve even light distribution across your canopy.
Superior Thermal Performance
Contrary to popular belief, LED fixtures generate heat. However, COB LEDs produce less infrared radiation compared to HPS bulbs, making them run cooler. This heat reduction contributes to a more favorable growth environment for your plants.
COB LEDs Compared to Other Types of Grow Lights
To understand where COB LEDs stand in the realm of grow lights, let’s compare them to other options. Here’s a breakdown of COB LEDs compared to different types of grow lights:
| Quality | COB LED | HPS | MH | CMH | CFL |
|---|---|---|---|---|---|
| Price | 2 | 4 | 3 | 1 | 3 |
| Power Use | 5 | 4 | 2 | 3 | 2 |
| Spectrum | 5 | 3 | 2 | 4 | 3 |
| Efficiency | 5 | 4 | 3 | 3 | 2 |
| Lifespan | 5 | 3 | 2 | 3 | 2 |
| Total | 22 | 18 | 12 | 14 | 11 |
