Household LED lamps
Many LED lamps have become available as replacements for screw-in incandescent or compact fluorescent light bulbs, ranging from low-power 5–40 watt incandescent bulbs, through conventional replacement bulbs for 60 watt incandescent bulbs (typically requiring about 7 watts of power), and as of 2010 a few lamps were available to replace higher wattage bulbs, e.g., a 13-watt LED bulb which is about as bright as a 100W incandescent.(A standard general purpose incandescent bulb emits light at an efficiency of about 14 to 17 lumens/W depending on its size and voltage. According to the European Union standard, an energy-efficient bulb that claims to be the equivalent of a 60W tungsten bulb must have a minimum light output of 806 lumens.)recommend LED Strip: smd 3528 flexible led strips
Most LED bulbs are not designed to be dimmed (although some models are designed to work with dimmers), and are usually directional. The lamps have declined in cost to between US$30 to $50 each as of 2010. These bulbs are more power-efficient than compact fluorescent bulbsand offer lifespans of 30,000 or more hours, reduced operated at a higher temperature than specified. Incandescent bulbs have a typical life of 1,000 hours, compact fluorescents about 8,000 hours.An LED light bulb can be expected to last 25–30 years under normal use. The bulbs maintain output light intensity very well over their life-times. Energy Star specifications require the bulbs to typically drop less than 10% after 6000 or more hours of operation, and in the worst case not more than 15%.They are also mercury free, unlike fluorescent lamps. LED lamps are available with a variety of color properties. The higher purchase cost than other types may be more than offset by savings in energy and maintenance. recommend LED Strip: smd 3528 led light strips
Several companies offer LED lamps for general lighting purposes.The C. Crane Company introduced a 7-watt replacement for a 60-watt bulb, the "Geobulb",with an efficiency of 59 lumens/W.The company also offers wedge-base lamps for replacement in low voltage fixtures. In the Netherlands, a company called Lemnis Lighting offers a dimmable LED lamp called Pharox.The company Eternleds Inc. offers a bulb called HydraLux-4 which uses liquid cooling of the LED chips.Philips makes a number of LED lamps which are commercially available in the United States and come with a six year warranty, and a number of smaller producers can be found that sell LED lights that are screw-in replacements for conventional bulbs,for example, the General LED Bulb from Arani
The technology is improving rapidly, and new energy-efficient consumer LED lamps have been announced from three of the lighting industry's largest producers, Osram Sylvania, Philips, and General Electric,so these listings should be taken as not necessarily representative of what is currently available. recommend LED Strip: waterproof 5050 led strip
