I can only agree with the many opinions here, really very good luminous efficacy and very good light geometry. However, the burner hold only about 6-9 months (from September until March daily about 1 hour on, in the summer only sporadically). Meanwhile, with me out of the second set, in this case everyone has to weigh himself.
But despite the low life expectancy me is the top illumination worth the money to put safety first.
