Actually, I have reviewed a Preon 2 Neutral White (XP-G R4), and more recently had an opportunity to briefly test a High CRI version.I recently bought two of the Ti high CRI versions. They were listed as 160 lumens like the r5 vers., they look pretty bright, but not quite as bright as my Preon 1 S2 converted to a Preon 2 XPG-S2 which is crazy bright for a pen light. It would be interesting to know how bright these high CRI versions are, it's hard to tell because the beam color is so drastically different. Looks amazing though, colors pop like crazy.
Yes, I have also found that the Preon 2 works fine with L92 lithium. Here is a runtme from a more recent review:Will the Preon 2 work with the Energizer Ultimate Lithiums? I believe that they are 1.5v each but not sure. I saw the referecne to the Energizer L92's but not familiar with them. Thanks in advance for any helpful responses.
You are right - the Lo on the Preon 2 should last about twice as long 2xAAA as the Preon 1 (as the output is about the same). This is another example of how the Foursevens specs are often conservative. I would consider them as minimal reference specs, as opposed to typical ("average") performance.So my question is why isn't the runtime more on low with double the batteries? The foursevens website lists both the preen 1 & 2 on low mode as lasting 23 hours. Shouldn't the preon 2 last longer. Sorry if this is a stupid question.
