You have mentioned this before in the
Tax on Lightbulbs
Thread, Cyfr took time and effort to explain the difference to you, you even thanked him for his explanation about how and why your calculator doesn't run from a low energy bulb and now you repeat the same inaccurate tale, you cannot compare the two different light sources by using a solar powered calculator and all you are managing to do is confuse the issue as you did in the earlier thread.
I totally agree with the comment made by Madhatter in that earlier thread.

Jambutty tries to confuse things MP, it's very simple, a flourescent gives out more light, a 21watt is equivelent to a 100watt.
