Will CMH Grow Light Produce Better Quality Buds than COB LED Grow Light?

What is CMH Grow Light?
The crux of the matter; what are LEC lights and why are they sometimes called ceramic metal halide (CMH) or ceramic discharge metal halide (CDM)? Thankfully, all terms mean the same thing, and as awareness of the technology increases, these terms are becoming interchangeable. An LEC light uses a ceramic arc tube, rather than the quartz version found in regular MH lights. The result is a more natural colour, producing more lumens per watt and lasting a lot longer. The most common model of LEC fixture is the 315W with a “4200K” colour bulb.

What is a COB LED?
A COB (short for Chip-on-Board), is an LED packaging technology that describes mounting multiple LED chips directly onto a substrate to form a single module. Multiple LEDs, minuscule in size, are wired and packaged together into a single ceramic or copper board so that they function as a sole light source.

When a COB LED grow light is energized, it appears more like a lighting panel than multiple individual lights as usually the case with other LED packages, like when using several SMD LEDs mounted closely together.

Pros of CMH Grow Lights

• LECs last on average twice as long as MH or HPS bulbs.
• LECs, because of the ceramic element, burn much hotter than MH, producing a light closer to that of natural sunlight. Due to their insulating value though, they also have a lower heat output, which means there is less likelihood of burning plant leaves as compared to MH or HPS bulbs.
• LECs can produce light spectrum sufficient to support both the vegetative stage of plant growth as well as its flowering stage.

Cons of CMH Grow Lights

• Heat Generation: I know this is also listed as an advantage above. Quality CMH grow lights emit much less heat than HPS or MH, but still more than LED.
• Flowering: CMH grow lights are very good at flowering, especially those with a warmer color spectrum (around 3000K), like the Philips 3100K bulb we recommend.

Pros of COB LED lights 

• These lights have more number of diodes as compare to SMD lights. Hence from a small amount of energy or watt it generates higher amount of energy.
• Since these lights can produce higher amount of light from smaller space, these lights are efficiently used in flash lights of a camera or mobile phone
• These lights generate higher lumen lights in less watt. Also, the heat generation is very less as compared to other lights. This aspect makes it very appropriate for indoor plantation as it would not require separate cooling agents.

Cons of COB LED lights 

• These lights do not emit different colours as compared to SMD lights. It output comes in a single colour. Hence, chip on board LED lights cannot be used as colour changing bulbs like SMD lights.
