MR16 12V 5W LED spot, Led Spot Light, High Power Leds, 3x2watt Gu10, Mr16, Par20, Jdr E27
halogen bulbs, Exactly the same length and diameter as a standard halogen lamp, LED Spotlights are available in a range of optical beam angles from 6 to 25 degrees, so you can choose how intense a spotlight you require - narrow beam for a dedicated reading light, wide beam for more diffuse mood lighting. They come in industry standard fittings
High power LEDs (HPLED) can be driven at hundreds of mA (vs. tens of mA for other LEDs), some with more than one ampere of current, and give out large amounts of light. Since overheating is destructive, the HPLEDs must be highly efficient to minimize excess heat; furthermore, they are often mounted on a heat sink to allow for heat dissipation.
light-emitting diode (LED) is an electronic light source. modern LEDs are available across the visible, ultraviolet and infra red wavelengths, with very high brightness.
