Great review....I will be picking one of these up after finding out you can put a clicky tail switch on it, thanks for the comparison

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.

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. :whistle:

The Neutral had exactly the same output/runtime curve as the original Cool White (Xp-G R5) I tested in this review. That is to say, ~190 ANSI FL-1 lumens, levelling off to ~160 lumens after 15+ mins, with a 50% runtime of ~50mins on eneloop.

The High CRI had ~140 ANSI FL-1 lumens, levelling off to ~120 lumens after 15+ mins, and with a 50% runtime of ~50mins on eneloop.

Take those lumen estimates with a bit of salt, as I can't be sure my lightbox correctly interprets the tint differences any better than the human eye does.

Cool! Those figures don't surprise me. Not bad at all.. My XPG-S2 Preon 1 converted to a Preon 2 is really nice and bright, probably even a little more than the r4/5, but it does get very warm, very quickly. Still it's always amazing to me how bright it is for a ''pen light''...

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.

Yes, I have also found that the Preon 2 works fine with L92 lithium. Here is a runtme from a more recent review:

The Preon 2 was the first "real" flashlight I bought. Great EDC light.

Hey,

Perhaps this is a stupid question, but how well has it held up to hard use? I'm looking at picking up a P2 but can't help feeling that it looks a little delicate ??

Thanks

Similar question here. I would think the Preon 2 will accumulate scratches quite each, maybe more or less noticeable depending on color choice, but should still hold up over time given the materials. Any feedback on long-term use?

Ok so I just bought a preon 2 body for my preon 1 Ti. It's my understanding that the medium and high modes are brighter, but the low mode is about the same (around 2 lms). 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.

I use a Preon 2 head with a P1 body (I think the heads are the same) with a clicky switch and AAA sized lion battery
Works great. bright enough

In fact I have two and Vinh modded one to Nicha 219

Great EDC

I agree it's a great EDC and the heads are interchangeable. My question was about the runtime on the Low mode for both preon 1 & 2. If they are about the same, shouldn't the preon 2 runtime on Low mode be longer with double the batteries?

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.

I'm heading to the website to get one of these. What is the CPF discount code?
