Okay so I have been looking for a cheap source of lighting and wondered about using incandesents. How much of the wattage is actually light energy?I imagine a lot of the energy is heat energy. I have tried energy savers but they are almost as expensive as T5s.
Like this. I presume it is no good but it is worth a shot. Any thoughts?
