The Ceramic discharge metal halide (CDM) lamp is a relatively new source of light that is a variation of the old (high-pressure) mercury-vapour lamp. The discharge is contained in a ceramic tube. During operation, the temperature of this ceramic tube can exceed 1200 Kelvin. The ceramic tube is filled with mercury, argon and metal halide salts. 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 DCM 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.
CDM lamps give five times more light than comparable tungsten incandescent light bulbs (80-117lm/W) and retain colour stability better than most other gas discharge lamps.
Applications for these lamps include television- and film making as well as shop lighting, digital photography, street- and architectural lighting.
Lower wattage smaller cubage higher luminenscence long life
PAR 38 infrared lamp is one of the main productions in our company.it can be applied to stockbreeding and beauty care,the pressed glass with high rigidity,good aseismatic performance and heat resistant,which made up the lamp cup is different from the glasses used on general infrared lamp,the color temperature is 2000-2200K,the average life is 3000H,the lamp transform electric energy into infrared heat,hence it can use for the fowl's hatch in winter,the radiant heat preservation can made the stockbreeding cost lower.compared with other heat preservation way,it offers lower cost,easy installation and keeps air clean in the room,now the lamp is applied to stockbreeding extensively.as well as beauty industry and medical treatment. Different varieties of infrared lamps watts and volts offered,including 100W/150W/175W,and 120V/230V it can make special watts and volts by customer's request. By air packed in box
