I have never stated that the new LE bulbs are not cheaper to run. Indeed I have acknowledged that they are.

My point is that they are not as cost effective as the normal light bulb when you take into account the cost to buy and the life of each type, as I have already explained.

My other point is that a LE bulb rated at 60w but in fact uses 11w of energy is not quite as bright as a normal 60w bulb that uses 60w of energy. My proof being that with my calculator being a fixed distance from a light source needs to be closer to an LE bulb than it does to a normal bulb to work. All this spectrum stuff was introduced by Cyfr in some attempt to discredit my observations about my calculator.
