Shabbat Lamp
A Shabbat lamp is a special lamp that has movable parts to expose or block out its light so it can be turned "on" or "off" while its power physically remains on. This enables the lamp's light to be controlled by those Shomer Shabbat, Shabbat observant Jews who accept this use, to make a room dark or light during Shabbat without actually switching the electricity, electrical power on or off, an act prohibited by Orthodox Judaism on both Shabbat and the Jewish Holidays. Shabbat lamps for children, such as the teddy bear pictured here, have features for covering the light without tampering with electricity. Under the bear's hat is a black shell that turns to completely hide the lightbulb. Halakha of the Shabbat lamp There are various halakha, Jewish laws governing Shabbat lamps that enable their use by those who permit controlling them during Shabbat. The lamp itself cannot be moved from its location due to the laws of muktzah. However, most authorities agree the component that is u ...

Compact Fluorescent Lamp
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs. The lamps use a tube that is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp. Compared to general-service incandescent lamps giving the same amount of visible light, CFLs use one-fifth to one-third the electric power, and last eight to fifteen times longer. A CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime. Like all fluorescent lamps, CFLs contain toxic mercury, which complicates their disposal. In many countries, governments have banned the disposal of CFLs together with regular garbage. These countries have established special collection system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabbath Mode
Sabbath mode, also known as Shabbos mode (Ashkenazi pronunciation) or Shabbat mode, is a feature in many modern home appliances, including ovens, dishwashers, and refrigerators, which is intended to allow the appliances to be used (subject to various constraints) by Shabbat-observant Jews on the Shabbat and Jewish holidays. The mode usually overrides the usual, everyday operation of the electrical appliance and makes the operation of the appliance comply with the rules of Halakha (Jewish law). Background Halakha forbids Jews from doing "work that creates" on Shabbat. Observant Jews interpret this to include various activities including making a fire, preparing food, or even closing a switch or pressing an electronic button. A range of solutions has been created for those who need to use electronic (or electronic-controlled) devices on the Shabbat, including a special "Sabbath mode" for otherwise standard appliances. "Sabbath mode" is a term introduced by manufacturers and does not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shabbat Clock
Many Jews who strictly observe Shabbat (the Sabbath) refrain from using electrical devices on Shabbat, with the exception of passive enjoyment of devices which were set up before Shabbat. Various rabbinical authorities have pronounced on what is permitted and what is not, but there are many disagreements in detailed interpretation, both between different individual authorities and between branches of Judaism. In Orthodox Judaism, it is generally discouraged to use electrical devices on Shabbat, but Orthodox Poskim (authorities) of Jewish law have disagreed about the basis of this claim since the early 20th century. Many Orthodox leaders have held that turning on an incandescent light bulb violates the Biblical prohibition against igniting a fire. However, the reasons for prohibiting the operation of an electrical appliance that does not involve heating metal to glowing temperatures (which is considered like kindling a fire because of the heat and light), are not agreed upon. ...

Incandescent Light Bulb
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. Incandescent bulbs are much less efficient than other types of electric lighting, converting les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jewish Holidays
Jewish holidays, also known as Jewish festivals or ''Yamim Tovim'' ( he, ימים טובים, , Good Days, or singular , in transliterated Hebrew []), are holidays observed in Judaism and by JewsThis article focuses on practices of mainstream Rabbinic Judaism. Karaite Judaism#The calendar, Karaite Jews and Samaritans#Samaritanism, Samaritans also observe the biblical festivals, but not in an identical fashion and not always at exactly the same time. throughout the Hebrew calendar. They include religious, cultural and national elements, derived from three sources: biblical '' mitzvot'' ("commandments"), rabbinic mandates, and the history of Judaism and the State of Israel. Jewish holidays occur on the same dates every year in the Hebrew calendar, but the dates vary in the Gregorian. This is because the Hebrew calendar is a lunisolar calendar (based on the cycles of both the sun and moon), whereas the Gregorian is a solar calendar. General concepts Groupings Certain term ...

Lamp Shade
A lampshade is a fixture that envelops the lightbulb on a lamp to diffuse the light it emits. Lampshades can be made out of a large variety of materials like paper, glass, fabric or stone. Often times conical or cylindrical in shape, lampshades can be found on floor, desk, tabletop, or suspended lamps. The term can also apply to the glass (or other materials) hung around many designs of ceiling lamp. Beyond its practical purpose, significant emphasis is also usually given to decorative and aesthetic features. A lamp shade also serves to "shade" human eyes from the direct glare of the light bulbs used to illuminate the lamp. Some lamp shades are also lined with a hard-backed opaque lining, often white or gold, to reflect as much light as possible through the top and bottom of the shade while blocking light from emitting through the walls of the shade itself. In other cases, the shade material is deliberately decorative so that upon illumination it may emphasize a display of col ...

Muktzah
Muktzeh (Hebrew: "separated") is a concept in Jewish rabbinical law. Muktzeh objects are subject to use restrictions on the Sabbath. The generally accepted view regarding these items is that they may be touched, though not moved, during Shabbat (the Jewish Sabbath) or Yom Tov (Jewish holiday). Some extend this prohibition to the actual handling of these items. Halakha defines various categories of objects or substances which are "set aside" on the Jewish Sabbath, as well as various permissible instances of moving these various ''muktzeh'' items. For example, one may not handle money, rocks, twigs, etc. on Shabbat, as these items are ''muktzeh''. The consensus among the halakhic authorities is that muktzeh is an '' issur d'rabbanan'' (a rabbinic prohibition), rather than a ''d'oreisa'' (biblical prohibition). The laws of muktzeh can be divided into two distinct subjects: * "Muktzeh", i.e. the conditions needed for something to become muktzeh, ''and'' the properties of the vario ...
