It will never work they bleat.
Well, if you haven't heard of Haitz's Law then this might surprise you.
Haitz's Law, named after former Agilent scientist Roland Haitz, is the
led equivalent to Moore's Law in the computer chip industry (Moore's Law asserts that chip performance doubles every 18 months)
Haitz's Law holds that each decade the prices of LED lights fall by a factor of 10 while performance grows by a factor of 20. This isn't idle speculation either: it is matter of historical fact ...
... Luddite voices that energy saving lighting in the form of domestic LED lights is too expensive and can't compete with conventional incandescent lighting for brightness and range of applications. It will never work they bleat.

Now consider also that Moore's Law (which explains the phenomenal growth of all things based on the computer chip) has an
led equivalent. Haitz's Law holds that the performance of LED chips grows by a factor of 20 while their price drops by a factor of 10 over the span of each decade.
At present the performance of domestic LED lighting is doubling roughly every 18 ...

Consider the convergence in recent years between computers, cameras, and mobile phones with a rich variety of media available including pictures, video and music. Now consider also that Moore's Law (which explains the phenomenal growth of all things based on the computer chip) has an
LED Equivalent. Haitz's Law holds that the performance of LED chips grows by a factor of 20 while their price drops by a factor of 10 over the span of each decade.

So how do we compare the two?
As a rough guide, simply divide an incandescent wattage rating by ten and add a bit. So for example, to replace a 60w halogen lamp (both 12 volt MR16 and GU10 mains fittings are commonly available for
led equivalent replacements) then you would most likely being looking at an LED spot light rated at 7w. Move up to say 12w and your LED is taking on a regular floodlight.
Some manufacturers do state an equivalent conventional wattage for their LED bulbs but experience ...
... amount of electricity since nearly all their input power is converted to light rather than wasted as heat. So how do we compare the two?

Some manufacturers do state an equivalent conventional wattage for their LED bulbs but experience suggests you take these with a heavy pinch of salt. ...
A regular 60w incandescent light bulb has a life of little more than 1,000 hours which means you will have to purchase a whopping 50 replacements over the same life span as an
led equivalent.
Multiplied by billions of people, that's cost, waste and pollution on a truly heroic scale. And the answer to this colossal problem is, perhaps surprisingly, not to be found in a colossal solution, but in modest actions by ordinary people like you and me. Even a few small steps can produce a huge result when magnified by each ...
