To be sure, to be subject to no mistake, I have the lamps, side by side, both tested with the meter and the meter of the camera. (See Fig.) The subjective impression has Confirm. Direct the focus of the reflectors, a significant difference in brightness can be made out. Approximately 30-40% less light output. This is very disadvantageous particularly in mirror nearby.
In conclusion: really neat and technically well-designed radiators, unfortunately not nearly as bright, and that weighs heavily here, as 20 watts halos. However, light color and beam angle are really very good.
Too bad, then, and I have to continue to look for a replacement for my Funzeln.
