From the results of the experiment will be found that LED to the highest S/p which is appropriate per the usage in mesopic conditions, such as by having tubes fluor powder is greater incan., respectively.
The result is that LED bulbs will cost S / p max, which are suitable for use in most mesopic conditions as well, with fluor tubes and tubes with the incan lower respectively.
From the experimental results showed that LED tube is S / P maximum, which is appropriate to use the most mesopic condition as well as the tube fluor. And a tube with Incan decreases, respectively.
