For those who dont understand
lighting terms, hope this clears things up...
A power source for HID or fluorescent products that provides starting voltage and regulates the operating current.
Rendering Index):
A rating system that indicates how colors appear under a given light source (lamp) on a scale of 100.The higher the CRI number, the more accurately the objects color will be represented. The lower the CRI number, the less accurately it will be represented.
The level of electric pressure in the system. Note: Please verify the voltage for your specific application prior to ordering lighting fixtures.
A low-pressure electric-discharge lamp where the electric discharge generates light. It requires a ballast to operate and provides great energy efficiency and good CRI.
(High Intensity Discharge) An electric-discharge lamp in which light is produced under high pressure. It requires a ballast to operate. Metal halide (MH) and high pressure sodium (HPS) are two common types of HID lamps.
Sodium (HPS) Lamp
A high-intensity-discharge lamp in which light is produced through the energizing of sodium vapor in a pressurized arc chamber. It requires a ballast to operate and produces a yellow/orange light with very good lamp life and poor CRI.
Lamp:
A high-intensity-discharge lamp in which light is produced through the energizing of metal halides in a pressurized arc chamber. It requires a ballast to operate and produces a white light with good lamp life and good CRI.
An output device that converts electric energy into light.
A rating that is based on the assumption that 50 percent of the lamps, on average, are expected to remain burning at the number of hours indicated.
The amount of light expressed in lumens that a lamp source produces. All lamp-lumen data are based on initial lamp lumens.
A measurement in Kelvin (K). Light sources with a lower Kelvin temperature (2000-3000K) exhibit more light in the red/orange/yellow range. The higher Kelvin temperatures (>5000K) will exhibit more blue light. Fluorescent (2700K), quartz halogen (2800K) and metal halide (4000K) lamps produce an impression of "white" light.
Examples:
1500K Candlelight
2100K High pressure sodium lamp
2700K General-purpose incandescent lamp
2700K Fluorescent lamp
2800K Quartz halogen lamp
4000K Metal halide lamp
A unit of measurement of light emitting from a lamp or light fixture.
Watt:
A measurement of power consumption.
