It’s about time to Start using LED Spot Lights
Posted on Saturday May 12, 2012 Under Team EffortFor most individuals, most likely the greatest single element against low energy Led spotlight as a substitute for the soon-to-be-phased-out normal incandescent light bulb is the cost differential. There’s no doubt that an LED equivalent light bulb (for instance a 6w LED SpotLight as a direct replacement to get a 35w GU10 halogen lamp) is considerably more expensive than either the original or a CFL alternative.
Partially related to the observation above, is that the price of LEDs drops by a factor of twenty over the course of each decade. This characteristic is reliably predicted by Haitz’s Law (very comparable to Moore’s Law for computer chips and for comparable factors, principally because LEDs are, just like pc chips, pure electronic devices). Haitz also states that LED performance (amount of light per watt of electrical energy) increases tenfold more than exactly the same decade.
The cause for this is simple: the cost of electrical lighting will be the cost of the energy i.e. electricity. It matters not one jot what the actual bulbs cost; it is what it expenses to run them that really counts. Also, since LEDs final for tens of thousands of hours (in practice, decades of use) you only need to pay the purchase cost once, unlike normal bulbs which final only upto two thousand hours or just more than one year.
The concern about luminosity stems largely from historical notions of Led downlight applications such as LED lights and pocket torches that are clearly not capable of providing anything close to useable domestic lighting. Nevertheless, you could right now buy one of the newest Sharp Zenigata LED series of light bulbs that is rated at 80 lumens per watt.
