Any downside to large CLR values?

[spi]

I have one of those green super-brights.  Most circuits say 4k or so for CLR.  I had to use a 156K to tame the brightness to where it wasn't blinding to me (I just kept doubling it until it started dimming--hardly noticed a drop until I got to 80K or so).

Is there a downside to having such a large resistance such as I did?

I'm going to risk my reputation from years of expertise and say: no problem. 

156k seems exceptionally high compared to what is typical, but if your LED was designed to be blindingly bright, then it is probably fine.

I agree with Eric.  I've used up to 100K for the LED CLR.  For battery use, the bigger the better.

+1 agree with Willie. The bigger the better. Less current used, less likelihood of a sudden thump on the power rail when the LED comes on, etc etc. I can't see a good reason why you'd want a *smaller* value, if I'm honest. As long as it's bright enough, do it.

Rub the nose of the LED on a brick.

If it is THAT bright it is probably also a very narrow beam. Scuffing the lens will scatter light. Less stab in the eye, better reading at extreme angle.

Sandpaper will work also.

Thanks for the replies.
