Cheap grow lights UK

Grow lights have many forms, from compact fluorescent lighting (CFL) to high-pressure sodium lights (HPS), from Ceramic Metal Halide CMH/CDM GROW LIGHT to LED grow light. So we guess that you need to know which is cheap grow lights UK?

How to choose suitable and cheap grow lights UK?

As everyone knows that all plants need a source of light to enable them to photosynthesize and produce energy in a natural place. But when growers plant indoor, greenhouses and large horticultural projects, they need to consider choosing and buy suitable and cheap grow light in UK.

This is where horticultural lighting or  ‘grow light’ comes into play indeed. As we all know, after years of research and development, there are now five types of grow lights:

1. Incandescent

2. Fluorescent

3. HID (high-intensity discharge)

4. Ceramic Metal Halide lamp (CMH grow light)

5. LED Grow lights

This text will introduce  Ceramic Metal Halide CMH/CDM Cheap grow lights UK firstly for all and know us deeper:

This light is a type of ceramic metal-halide lamp which is 10-20% more efficient than the traditional quartz metal halide and produces a superior color rendition (80-96 CRI).

Applications for these lamps include television and film making, shop lighting, digital photography, street lighting, architectural lighting and agricultural lighting including grow lights. A CMH light was first exhibited by the Thorn Lighting Group in 1981 at the Hannover World Light Fair, and the first commercial CMH lamps were distributed by Philips in 1994.

The ceramic metal halide is a variation of the metal-halide lamp which is itself a variation of the old (high-pressure) mercury-vapor lamp. A CMH uses ceramic instead of the fused quartz of a traditional metal halide lamp. Ceramic arc tubes allow higher arc tube temperatures, which some manufacturers claim results in better efficacy, color rendering, and color stability.

The discharge is contained in a ceramic tube, usually made of sintered alumina, similar to that used in the high-pressure sodium lamp. During operation, the temperature of this ceramic tube can exceed 1200 kelvins. The ceramic tube is filled with mercury, argon and metal-halide salts (for example, sodium iodide). Because of the high wall temperature, the metal halide salts are partly vaporized. Inside the hot plasma, these salts are dissociated into metallic atoms and iodine.

The metallic atoms are the main source of light in these lamps, creating a bluish light that is close to daylight with a CRI (color rendering index) of up to 96. The exact correlated color temperature and CRI depend on the specific mixture of metal halide salts. There are also warm-white CDM lamps, with somewhat lower CRI (78-82) which still give a more clear and natural-looking light than the old mercury-vapour and sodium-vapour lamps when used as street lights, besides being more economical to use.

The ceramic tube is an advantage in comparison to earlier fused quartz. During operation, at high temperature and radiant flux, metal ions tend to penetrate the silica, depleting the inside of the tube. Alumina is not prone to this effect.

Average life span: up to 20,000-24,000 hours.

CMH (Ceramic Metal Halide) is the modern version of the old HID MH type of light. CDM produce full-spectrum light and produce high-quality crops. From 2003 till now, many growers supply their requirements to our professional technical team who will supply OEM service to choose and use digital ballast, 315w grow light, 630w grow light, 1000w led grow lights UK, and other cheap grow light in UK.
