COB (Chip-on-Board) grow lights are the latest in LED grow light technology. Instead of growing with dozens or hundreds of individual diodes, COB technology combines everything into a single chip.

Benefit: COB lights provide a greater uniformity as well as strengthened intensity.

Why Grow with COBs?

COB LEDs are more powerful than traditional 3 Watt and 5 Watt diodes, giving you stronger canopy penetration. When growers claim that LEDs "don't work" it's usually because they don't see the same kind of canopy penetration as an HPS bulb. COBs fix that.

Including greater electrical efficiency, a higher spectrum, and longer lifespans, chip-on-board (COB) lights are high quality grow lights that have many advantages. However, the primary benefit is that they emit less heat than standard LED bulbs. This means you’ll be able to get more light in less space. In other words, they’re more efficient than traditional LEDs. When compared to standard LED and HID Lights, LED COB lights to create less heat and have a higher spectrum. This enables you to reduce grow room hot spots because the overall light distribution is greater.

Which COB Should I Get?

Our most popular COBs are made by Amare LED. They use high-quality components for everything from the diodes and drivers to the fans and heat sink. These lights are built to last.

They use a full-white spectrum that mimics the sunlight at the equator to give optimal growth. The other cool thing about Amare's is that each COB is surrounded by 10 monochrome LEDs. This helps even out the light's overall spectrum. Also, if the light from the COB is too strong for your seedlings or clones, you can get healthy early-stage growth by turning off the COBS and only using the monochromes.

If you're looking for a high-quality grow light to cover a 4' x 4', it's hard to beat the Amare SolarEclipse 450. It has 6 COB didoes, only pulls 450 Watts, and even has a supplemental UVB lamp to increase resin production.

Want to try out COBs on a smaller grow? Johnson Grow Lights makes our smallest and most affordable COB grow light, the CX-1L. It’s got one COB LED and is perfect for growing a single small plant.

Take advantage of this new COB technology to bring your crop to the next level!
