The End of LED Grow lights?

Not really, just in the way most people today think of LED Grow Lights.

New MCOB LEDs are replacing 3 and 5 watt LED Arrays in indoor horticulture cultivation.

Watching LED Technology advance is like a long ride on a bullet train, so much is happening it can be hard to keep up with some of the most current technologies, and how they are revolutionizing the indoor horticulture ‘Grow Lights’, here are the 5 main LED Technologies today.
DIP, SMD, HB Pakage, COB and now MCOB

Most think of DIP LEDs as the only kind

'High Flux Density' 3 watt LEDs are super common now.

COB-pic1

Chip on Board use a plastic or ceramic substrate, limiting thermal capabilities

 

MCCOB is often wrongly referred to as MCOB

Common for strip lights but not powerful enough for Horticulture

Multiple Chips On Board or MCOB is really a much simpler (and efficient) way to package LEDs together in a small space. When  manufacturing companies buy their HB LEDs they typically come on a ceramic base, connected and soldered to a PCB board and then finally onto a heat-sink.

MCOB bonds the LEDs right to the heat sink. Effectively removing 2 thermal barriers, drastically affecting the performance and lifetimes of the LEDs.

The benefits for indoor cultivators and greenhouse gardeners are evident, when the 9 or 10 different spectrum of LED chips are mixed in a certain ratio and placed together in groups, the light mixes together perfectly mere inches away from the surface, providing a purple tinged light that would not be pleasant to humans for long periods, but provides exactly what the plants require.
100 watt and 200 watt LED Chips?

MCOB come in many sizes: 20, 50, 100 and newly developed 200 watt MCOBs are being released in early 2015

MCOB look different from all other LED Grow lights

MCOB also have another feature lacking in today’s LED Grow lights, easy repair and upgrade-ability. 3 and 5 watt arrays can be problematic for repairs, the hundreds of screws and plastic lenses can easily get lost and soldering in new 3 watt LEDs may not be everyone’s idea of a good time. MCOB LED Grow lights have fewer parts and can easily be swapped out in a few minutes without necessarily having to return to store for repairs.

The end of 3 watt LED Grow lights is near.

COB and 2-5 inch Wafers are not commonly used in grow lights, well ones that work anyway!

COB LEDs are not exactly suitable for horticulture

The other quite new LED lighting technology would be: MCCOB ‘Multiple Chips and Cups on Board’ often referred to wrongly as MCOB

LED Continues to be one of the most important technologies developing today, it has evolved how we look at (and control) artificial light forever
