In conclusion, with advances such as these we can see that now, in addition to the concept of energy saving, the concepts of ecological and sustainable are added to the subject of lighting. Something very positive because we know that our planet is in need of all the ecological alternatives that we can provide.

Let us hope that apart from lighting, science and technology can continue to contribute to the capacity for sustainable development of our planet. Greetings @emiliomoron and thanks for your post
