Nos ha llegado esta linterna de luz negra como algunos la llaman, aunque en mi caso me gusta mas llamarla de luz ultravioleta, que no tiene nada que ver con otras linternas económicas en el haz de luz que da. La linterna es en si misma como otras muchas linternas de luz blanca, con interruptor que da potencia al 100% o al 50% y apagado. va con una batería extráible del tipo 18850 que en caso de perdida o deterioro le pones otra y de nuevo la estrenas. Ahora bien, en lo que destaca esta linterna es en el haz de luz que da, que es impresionante. Yo he tenido otras linternas de este tipo que a veces usamos para ver puntos de fugas de fluidos, sin embargo esta es impresionante todo lo que permite ver. Por ejemplo si uso una de las otras y alumbro la cama por ejemplo, no llega a verse toda la cantidad de polvo que puede haber en una colcha. He alumbrado las paredes de mi casa, y se descubren huellas de las manos de mis hijos en las paredes que con las otras linternas no se ven. Para ver por ejemplo la ducha y se ven todos los churretes que quedan que son totalmente invisibles a la vista, o con otras linternas mas económicas. Sinceramente es tener todo un mundo nuevo a la vista. Imagino que esto se debe a que las mas baratas lo que hacen es cambiar el led que usan en una linterna estándar, por uno de luz uv, mientras que esta linterna esta diseñada única y especificamente para dar luz uv. Se trata por tanto d euna linterna de uso profesional, que nos sirve para hacer lo mismo que hacen las otras pero a a un nivel mucho mas alto. Si la quieres para ver si un billete tiene o no tiene marca, esto esta sobredimensionado, y con una mas barata te apañas, pero si lo que quieres ver es restos orgánicos, busqueda de determinados fluidos químicos para localizar averías, cambios cromáticos etc etc etc esta es una linterna para ello. Eso si, como caiga en manos de una mala suegra y quiera auditarte la limpieza de tu casa, estas aviado!!! porque es capaz de detectar motas de polvo casi a los pocos segundos de haberlo limpiado. Mi mujer se ha puesto nerviosa con la linterna ya que desconocía todo el polvo que se acumula en una casa y que no es visible a nuestra vista.
