) But don’t trouble doing the math - there isn’t a uniform way to convert incandescent watts to LED watts. Instead, a special method of measurement should be employed: lumens.

You should also watch our choice of LED motorists and LED dimmers and RGB controllers to choose an influence source in your light-weight fixture.
