Interesting. The reason I ask about brilliance (in addtion to my experiences with LEDs in the business world) is that this year I replaced my Saturn bulkhead compass with the ITT/Danforth/Rule bulkhead compass. (They are the same compasses but the company(s) have been through a few mergers - hence the different names). The new and old compasses are largely identical, except that the incandescent bulb on the old unit has been replaced by an LED. What a piece of junk. You can hardly read the card on the new one, whereas the old one you could read from several feet away.
I have heard for many years the expression "but the new stuff doesn't have the problem the old stuff you are familiar with" and "the technology has really improved" and more often than not wound up disappointed. I have concluded that most of the the users of those expressions has no first hand experience with the old stuff. That is why I still prefer film cameras.
