Led Lighting



A Led (Light Emitting Diode) is a diode semiconductor that emits light. Led Lighting may have an important role in the energetic efficiency in our homes. Changing our regular lamps to Led lamps we can save up to 85% or more of the energy consumed and so we can reduce our light bill. 

The advantages of Led Lighting are an important decrease in our energetic consumption, saving money, a major lifetime (up to 50.000 hours operating) and it’s more environmentally friendly due to the fact that compact fluorescents lamps (CFL) have mercury inside, a heavy metal highly contaminating if it is exposed to the environment. 

So there are many advantages when it comes to using Led Lighting and the only inconvenience is that Led technology is still not advanced enough and so the price of good ones may be high. Despite that considering its low consumption it works out more economical in the long run.  

There is a huge variety of commercial options that enable us to change any kind of light lamp or CFL for an equivalent in Led technology. For example, a halogen light lamp of 50 W has an equivalent of 7 W in Led which implies a decrease of 86% in the final energetic consumption. That is reflected in saving 16 € per year for each lamp! (calculated within 6 hours working at 18 c€/kWh). So imagine you have 10 halogen lamps of 50 W each and you change them for a Led lamp of 7 W you will be saving 160 € a year approximately. A Led light that costs 50€ per unit is amortized in 3 years!! If you have linear halogen lamps you can save 94% of the energy and 55 € per year for each light bulb. 

Without doubt if you are thinking of reducing your energy consumption at home Led Lighting is a fantastic solution and a great way to save energy and money!

Menstrual Cup


A menstrual cup, also known as vaginal cup or simply silicon cup is an ecological alternative to regular feminine hygienic methods like tampons and pads. It is easy to use, consists of a silicon cup or latex that is introduced inside the vagina during the period days. Unlike tampons and pads the menstrual cup doesn’t absorb the fluid, instead it collects it inside in order to dispose of it later. 

Those cups are reusable and so that makes them environmentally friendly and enable us to avoid more than 11.000 tampons in a woman’s life. It also has an impact on our pocket due to the fact that its high price is amortized rapidly because of its durability. Another advantage is its conformability as you can wear it all night long and the inert properties of silicon provides a decrease in possible infections.

There also are some inconveniences as it’s difficult to find opinions about it because it’s a brand new product. You need to boil it in order to sterilize, it can be uncomfortable to use depending on where you are and like tampons at the beginning it is not easy to use.
 
This product is commercialized under different brands and some of them are: Moon cup, Femmecup, Lunette, Fleurcup, MeLuna... their price is between 15-30 € depending on the brand. So here is a greener alternative that you may consider!
