A ceramic metal-halide lamp (CMH), also generically known as a ceramic discharge metal-halide (CDM) lamp, [1] is a type of metal-halide lamp that is 10–20% more efficient than the traditional quartz metal halide [2] and produces a superior color rendition (80-96 CRI).

2020年3月2日 · What are CMH lamps? The largest difference between MH and CMH lamps is the Ceramic or “C” in CMH. This refers to the arc tube made of a ceramic material, similar to what is used for HPS lamps.

2021年5月18日 · Ceramic metal halide (CMH) grow lights, also known as Light Emitting Ceramic (LEC), are a newer type of grow light that outclasses most HID lighting.

Ceramic Metal Halide lamps (CMH) are often known as Ceramic Discharge Metal-Halide lamps (CDM). Philips' CMH bulbs have excellent colour stability and produce higher colour rendition. Our new-generation Ceramic Metal Halide bulbs are used …

2012年4月9日 · ceramic metal halide (cmh) MH lamps have a more full light spectrum than HPS or MV lamps, the latter considered to be older and less efficient technology. And, although MH lamps use fewer watts, they are brighter than the yellowish light produced by HPS lamps.

2023年8月18日 · CMH light stands for ceramic metal halide light. These types of lights are also called light-emitting ceramic grow lights. This is often shortened to LEC as an acronym.

Whereas normal metal halide lamps use quartz or PCA (Phosphorus Converted Amber), CMH lights use a ceramic composite for their arc tubes. This allows the filaments to burn hotter, creating more and brighter light than standard metal halide lamps. So …

The Philips GreenPower 315W Elite Agro CMH Lamp gives growers a compact lighting solution in a high-performance, long-lasting package. After 20,000 hours of use, this ceramic metal halide (CMH) bulb still puts out 85% of the maximum Photosynthetic Photon Flux (PPF)!

CMH lights were introduced in the 1980s, but with recent discoveries in horticulture research, it makes sense why many growers are utilizing this technology. The claim from CMH lovers is that your plants can enjoy a nearly full spectrum white light, very similar to natural sunlight that lasts longer than your HID counterpart.

CMH lamps combine the HPS technology (providing stability, efficiency & uniformity) and the Metal Halide Technology (providing bright white quality light) to produce highly efficient light sources with good colour rendering and consistent colour performance through life.
