Ceramic Lamps

2012-01-16T17:52:00.000+07:00

This ceramic lamps design ideas bring you modern lighting products with a unique personality. This lamp design made by hands with special combination of heating procedures, colors, and material technique. Ceramic mixed to crystalline and enamel materials with application of color lacquers for a style definition. Exclusively hand made and hand finished in Italy through a process of casting, drying and firing through a new technique developed only by this designer.

Pouring Light

2012-01-16T17:15:00.000+07:00

This is the case with the Pouring Light Lamp, a design inspired by a spilling cup of tea (it even has the tea bag inside for an extra lifelike effect). Even though it seems strange, this product can be moved around by grabbing the pouring liquid, it is sustained by spilled tea and it lights up with the help of a tea bag. Moreover, it has an impeccable design and can be easily integrated in almost any type of modern interior.

WEEE (Waste Electrical and Electronic Equipment)

2012-01-16T13:12:00.001+07:00

The Waste Electrical and Electronic Equipment Directive (WEEE Directive) aims to minimize the impact of electrical and electronic goods on the environment, by increasing re-use and recycling and reducing the amount of WEEE going to landfill. It seeks a achieve this by making producers responsible for financing the collection, treatment and recovery of waste electrical equipment and by obliging distributors to allow consumers to return their waste equipment free of charge.

Watt-Miser™

2012-01-16T13:05:00.003+07:00

A Watt-Miser™ lamp is term used by GE to indicate a reduced-wattage lamp with performance characteristics (life, light output, etc.) such that it can usually directly replace a higher-wattage product. Watt-Miser™ lamps are available in a wide range of incandescent and fluorescent lamp types.

Working Distance (Typical)

2012-01-16T13:00:00.002+07:00

The Working Distance shown is the distance from the front surface of the reflector rim to the film plane, in the optical system for which the lamp was first designed. In most cases, it provides a uniform plane of light for the intended aperture.

Work Plane

2012-01-16T12:59:00.000+07:00

Plane at which work is done and at which illumination is specified and measured; unless otherwise indicated, it is assumed to be a horizontal plane 30 inches above the floor (table-top height) having the same area as the floor.

Wavelength

2012-01-16T12:58:00.004+07:00

The distance between two neighboring crests of a traveling wave. The wavelength of light is between 400 and 700 nanometers.

Wattage Indicator Reduced

2012-01-16T12:57:00.002+07:00

Indicates that this is a reduced wattage option for lamps normally used in this application. Be sure to check wattage, lumens and life to determine which lamp is best suited to your needs.

Watt

2012-01-16T12:56:00.005+07:00

A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy (See Kilowatt Hour).

Warm White

2012-01-16T12:55:00.001+07:00

Refers to a color temperature around 3000K, providing a yellowish-white light.

Warm Up Time

2012-01-16T12:53:00.006+07:00

HID lamps typically take a few minutes to warm up to full brightness after starting. (See Warm-Up Time to 90%)

Warm Up Time to 90%

2012-01-16T09:33:00.005+07:00

The time it takes for a High Intensity Discharge lamp to reach 90% of light output after being turned on.

Wall Temperature (Maximum Bulb)

2012-01-16T09:32:00.002+07:00

The maximum operating bulb wall temperature in Celsius.

Voltage Surge

2012-01-16T09:31:00.001+07:00

Transients spikes in line voltage that can be harmful to electronic equipment like computers and electronic ballasts. Surge suppressors are often used protect against such transients.

Voltage (Design)

2012-01-16T09:26:00.003+07:00

For Automotive lamps, voltage at which the lamp is designed to provide the amperes, candlepower, and laboratory life characteristics. For Projection lamps, the voltage shown is the design voltage of the lamp, on which the life and wattage ratings are based. Lamps for which 115-120 is shown in the Volts column are designed at 118 volts. Lamps are available only in the design voltage(s) shown. When ordering lamps listed for more than one voltage, be sure to specify the voltage required. (Supply voltage variation can significantly affect lamp life.)

Voltage

2012-01-16T09:25:00.002+07:00

A measurement of the electromotive force in an electrical circuit or device expressed in volts. Voltage can be thought of as being analogous to the pressure in a waterline.

Volt

2012-01-16T09:24:00.003+07:00

A measure of "electrical pressure" between two points. The higher the voltage, the more current will be pushed through a resistor connected across the points. The volt specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 277 V) refers to the line voltage it must be connected to.

Visual Task

2012-01-16T09:24:00.000+07:00

The task associated with seeing; objects and details that must be seen to perform an activity.

Visual Comfort Probability (VCP)

2012-01-16T09:23:00.001+07:00

For a given lighting scheme, VCP is a ratio expressed as a percent of people who, when viewing from a specific location and in a specified direction, find the system acceptable in terms of glare . (See Glare)

Veiling Reflection

2012-01-16T09:20:00.002+07:00

Effective reduction in contrast between task and its background caused by the reflection of light rays; sometimes called "reflected glare." You might have dealt with veiling reflections when you have to tilt a shiny magazine to avoid glare so as to read it, or struggled with reading a computer monitor because of the reflection of a window or a light fixture (See Glare).

Valance Lighting

2012-01-16T09:17:00.000+07:00

Lighting from light sources on a wall typically above eye level, shielded by horizontal panels. The light may be upward or downward directed.

Ultraviolet (UV) Radiation

2012-01-16T09:15:00.003+07:00

For practical purpose, any radiant energy with the range of about 100-380 nanometers (nm). It is beyond the blue or violet region of the spectrum and is invisible the eye just like the silent "ultrasound" dog whistle is inaudible to the ear.
UV is divided into 3 regions.
UVA 100 to 280 nm
UVB 280 to 315 nm
UVC 315 to 400 nm
Some wavelenghts (180-220) produce ozone, some (220-300) are bacterical. spme (280-320) enythermal (redden human skin) others (320-400) cause secondary liminance (black light).

Ultra

2012-01-16T09:01:00.003+07:00

A common way referring the high-efficiency.

Uniform Product Code (UPC)

2012-01-16T09:00:00.000+07:00

Two-Pin Compact Fluorescent Lamps

2012-01-16T08:57:00.001+07:00

Type of lamps that have the glow bottle starter built into the base of lamp. Traditionaly 2-pin lamps are designed to work with electromagnetic ballast. (See Four-Pin Compact Fluorescent Lamps)
