12 to 16 watts of a light bulb, even if like to multiples specified.The

now for the first time different:
In him not stuck 12-90 normal white reflection light, but seven power
chips, each with 3 watts. Power together 21 watts, which may correspond
to a bulb of 60 to 100 watts - and that too with light collection!
