I really like the Fenix PD32 series. In fact I've modified two of them to XP-G2 (nice tint to my liking). They regulate well, are efficient and I just like the size and the way they look, along with being able to run a 18650. I like the side switch even though some on CPF don't.
So I went out and bought an LD12 recently because I wanted a single AA like the PD32 and the R5 version was on sale due it being an older LED, so I thought what the heck, I was just going to put my own XP-G2 in there anyhow. Besides I don't trust Fenix XP-G2 tints (got a horrible green tint on a PD32 once).
Long story short.........I did a runtime graph of the LD12 and to my surprise, the regulation wasn't as tight as I've known Fenix designs to be. So I thought I may have got a bad light and ordered another LD12 this past week...........and it does the same thing. :hairpull:
Here is the chart showing what I'm talking about.
Note the red. That is the Fenix LD12 on the 2nd to the highest mode. The high mode was OK without too much ripple but this 2nd one down was almost like a type of PWM on there. And the mode below this one (2nd brightest one) was also jumpy. Now you cannot see it with your eyes but I have to admit it kind of bothers me as I know it can be better. I mean take a look at the EagleTac D25A........one of the best regulated lights I have tested and more efficient.
I like Fenix but something has changed in my opinion. Because I bought an LD12 right after they came out and it did not have this embedded PWM. Note the light blue trace on the run time plot. That is the original LD12 of about 2 years ago.
