I have gotten in the habit of hanging an ultra G from the ceiling to light the computer keyboard. I got into it when mom would be napping in the recliner, But now I enjoy the effect of the room still dark but the computer in the nice
glow of the G. And with the use of nimh's it run's pretty much 24/7 since i forget to turn it off 8 outta 10 times.
well I got to thinking about the estimated life of nichia LED's, and others (I think the CMG stuff was nichia) as to the fact that they don't live in the 50-100,000 Hr's like we had been told. So I took it down and i put two new L91 lith AA's
that metered exactly the same, and got my other ultra's that was pretty identical in beam, throw, brightness to this "G" and darkend the room and studied the beam's.
It was very apparent the G was now more then noticably dimmer. i wonder if anyone has noticed this? it's usable, but lets say i would not have picked it out of a batch of other ultra's. (i'm sure someone else also does this, If possible, open up a few and check which Is brighter, tint, etc)
I got 4 ultra's,, two G's, and two std CMG ultra's. They were my first "good" aluminium LED light's, so i know them pretty well as far as which was a little brighter, or big spill Vs hotspot etc, so I am sure of what I am seeing. (in fact my least bright ultra is now brighter then the "nite lite" G.
wadda ya think? does anyone know at rate this happens? I think i remember the ultra's are not puched real hard like say a ARC AAA. discuss.VDG
