The LED light is amazingly clean and white as we expected, but regular LED?s just don?t have the output. This doesn?t mean LED?s are not up to the task. For a small, kings? ransom, there are LED?s (pictured right) available that when configured in a 45 LED array could more than match up to the 500W halogen shop light.
Are you really willing to pay the cost for such a light when a halogen lamp is so inexpensive? If you are willing, you're out of luck. From what we have seen no one as of yet is willing to build a kings' ransom LED shop light.
