Today, the lighting of a special lamp or candles on the eve of the Sabbath is regarded as a religious duty. The early Tannaim (the first generation of rabbis of the Mishnaic and Talmudic period) regarded it as a well-known practice so much so that their discussions often dealt with the minor details connected with it, sch as the kind of wick or oil to be allowed as opposed to its origin. While the Hebrew Bible does not explicity direct the lighting of Sabbath lights, it does prohibit the kindling of lights on the Sabbath. The inference therefore is to provide light before the onset of the Sabbath.
This means that as one moves away from a given light fixture, illuminance decreases drastically. For example, consider an incandescent light bulb that is rated at 300 lm. Standing one meter away from this light bulb, one obtains an illuminance of 300 lux (300 lx= 300 lm/1 m2). However, if one moves away from that light bulb an additional 2 meters (i.e., 3 meters total), illuminance changes to just 33 lux by the inverse square law (33 lx= 300 lm/3 m2).
Low voltage landscape lighting is often a do-it-yourself project and there are many options to suit your budget. Landscape lighting is also more affordable than ever coming in dozens of styles at a wide range of prices. Although it is tempting to purchase the cheaper incandescent lighting systems, in the long run the compact fluorescent options are better. Incandescent lamps will last for between 750 to 1000 hours. Halogens will last for 3500 to 5000 hours. But fluorescent lamps will last for as much as 10,000 hours. Because low voltage fluorescent light fittings have a lower power consumption than incandescent or halogens this makes them more desirable. Fluorescent light fittings also last longer than any other light fitting because they do not get as hot.
