I didn't bother with beam shots but I did finally get out tonight with the 325NLT and SST-20 4000k.
My observations are thus...
Please remember I have old eyes and a propensity for guzzling rum... and it was relatively bright out with the moon on two days away from being full.
NLT throws further. It is pushing out 100 more lumens and is 5000k. It does appear to my eyes that higher K generally will appear brighter, and thus appear to throw further. Take what I say with a grain of salt (preferably around the rim of a margarita glass) as this is simply my opinion.
Now, in the 0-75 yard range, the SST-20 blows away the NLT in color rendition. Granted it should as it is high CRI and the NLT is not, but I was once again dumbfounded at how much "clearer, sharper, lifelike" everything appeared compared to the NLT. My High Noon has been regulated to a diffuse reflector since the NLT came out, and now I am going to have to put a standard reflector back on it and do some comparisons with this SST-20. Yep. I know. I shouldn't be crossing the beams but I can't help it.
As a rule, I tend to keep away from tints under 5000k, but I do find this SST extremely pleasing to the eye at night. Maybe it's because I have spent the last few months using a lower CRI NLT... really made the difference pop for me... was like the desert was clearer... more in focus for my old eyes. I don't know.
I am just going to have to keep this one (though Henry put his old worn tail on it so I would bring it back... no kidding.). I'll figure something out but I'm not going to let this one slip out of my grimy little fingers anytime soon.
