Disadvantages of energy saving lamps

posted in: Blog, news | 0

First, they look ugly, as they consist of minimized fluorescent tubes that are either hidden in a housing or bent as tubes and left as exposed loops. Second, they are too expensive. Third and light planner Peter Andres calls this the “lived lie of the energy saving lamp” they buy their lower energy levels by only offering certain peaks of the visible light spectrum between 380 and 780 nanometers, which saves energy but considerably reduces the quality of light. Forth, each compact fluorescent lamp contains at least two milligrams of mercury, the lesser quality products as much as 10 milligrams, and it is well nigh impossible to remove it from the twisted tubes (cf.: one milligram is enough to render 5,200 cubic meters of water toxic). The “most poisonous non-radioactive material”, namely mercury, is not even worth a mention in the DGNB’s sustainability assessment, Andres reports. Fifth, some models release phenol vapor owing to the adhesives used to glue together the individual sections of the lamps. Sixth and finally, as so often is the case with autos, the consumption readings given for the compact fluorescent lamps are in part presented as better than they are. The data stated on the packaging is not always actually replicated when it comes to both service life and electricity requirements.
