If we are still that they continue with incandescent bulbs and we have not changed the low consumption and ledtry to make the comparison we’ve done with an incandescent bulb; It is true that only costs US 0.60 bulb, but after 30,000 hours of operation we will have spent approximately 240. so, you think about reasons to change all incandescent bulbs our home, community or Office and move us to low consumption or led. And after all this, manual override led or low power consumption?Much will depend on the investment that we want to do at the beginning; However if this investment is for a community or an Office, where we have to call to a electrician everytime you have to change the bulbs then thinks that if you put low consumption you will have to pay three times the services of an electrician while you will if you put lighting led, only you pay once an electrician service for a same period of time .There you’ll be thinking that I am going against my business to tell you thisSince I am a electrician, but before electrician I am a person and I like to tell you the truth on this matter so that you can make your decision thereon with all the information you need. If you ask me my opinion, provided that you can use led lighting, that if of good quality as have discussed you, since in many places you will find low-quality and low-light led bulbs.Also another advantage of led lighting that I have not commented yet, is that it gives us the same light from the first moment and low consumption takes a time to operate at full capacity, so it is not suitable for hallways, pantries, bathrooms, etc.Finally a look at lumen (light intensity) of each of the bulbs and veras light bulb led (300 lumens) has more performance than the light bulb low consumption (200 lumens) and consuming almost half. I hope they have served you guidance and useful this Informacionsi you want to know more about us, Tuelectricista.net, can visit us at the following link electricians Madrid if you want to read more tutorials ours can do so at the following tutorials link electricity.

The Herbarium

Handling a budget of zero zero pesos. That is the budget which has the biologist Carlos Parra for general administration of the Herbario Nacional Colombiano, of the National University Natural Sciences Institute. Zero pesos, repeats this Professor with a doctorate in taxonomy Botany from the University of Melbourne. That is why his work in this institution, which has 75 years of history, is almost paralyzed. The University does not gives us money, the State neither. We have between 35 and 40 thousand specimens of flora in deposits, without registration, without available to research. Due to lack of resources.

The Herbarium is held open thanks to a job with fingernails. The money you receive comes from external services provided in studies of environmental impact or identification of plants. But it is very little. Parra – who since the year 2000 is linked as a professor at the Institute and from the year past manages the Herbarium – says that despite having presented various projects at the University, nobody sees the importance of rescuing these collections. For him, it is vital to preserve the task of the Herbarium, as a record of plants that exist in a country. And not only is registered, but to study their use. Today the collection has 550 thousand registered specimens.

The others, on deposits, at risk of deterioration from possible attacks by pests. The little silver entering them is destined for contracts persons who classified plants, no more than two or three employees. Touched me to put in my pocket to buy cardboard, glue, tape, says the biologist. Parra has detained projects. We could publish more, more inventory, do more explorations of field, because many species are still unknown, but there is no how. I am committed to my work, but the situation is frustrating.
