Do the 25 lumens seem to you 4 times the power of the basic Stiletto? Or is it the Stiletto that is underated at 5 lumens? Thank you !!Funny question, does it taste good? 
Because I often put my Stiletto in my mouth, rather between my teeth when I needed my two hands ...moreover it must be less hard with the rubber finish ...
That is a great question I was just comparing the low modes outside and no the Pro does not "seem" to be 5x more like 1.5x brighter BUT with a nice hotspot. The regular Stiletto has no hot spot so if you want a nice hotspot on low with slightly brighter spill the Pro is better on low in my opinion.
The Pro specs claim 25lm for 23.5 hours while basic model is 5lm for 30hrs. So for me the slight loss of runtime in low is worth the brighter spill and the nice hotspot. The tint on the Pro is about the same as the standard model, I bought two Stiletto Pro's one for me and another as a gift and being able to turn them on through the package the two had the exact same color tint. I mention this because I generally prefer a pure white tint and when I bought my regular Stileto I bought it in a store and was able to check the tint before I bought it and all I checked had the same yellowish tint except one I finally found one that is slightly on the blue spectrum. As you can see in pic the Pro has the same package but I ordered straight from Surefire and got what I got but I'm actually satisfied with the tint it's great outdoors. I guess if you wait and purchase locally you might find a cooler tint if that is your flavor but it may be like finding a [emoji882].
It looks like the Pro is running the same emitter as the standard model which I think is XM-L and they have a tendacy to be slightly yellow especially on low modes but I would not call it a bad tint I would say it's more on the yellow nuetral than a cool blue. It's not my favorite tint in doors but outside especially on medium and high it's a very nice looking tint. I actually had to smile when I first clicked into high mode because of the fantastic output and the nice tint and I will admit after all these years of buying lights I guess I'm a little tough to impress but seeing a Stiletto light up my front yard so bright and colorful the Pro certainly had me a little giddy.
My opinion the biggest thing to prepare for is the extra weight and diameter of the bezel, the slim lightweight standard Stiletto is really why I've fallen so faithful to the Stiletto as my main EDC light and some of that is missing with the Pro with it's added bulk however I think I can adjust and I really want to because this output is a beast on high especially with the hotspot and like I mentioned the tint is very nice outdoors.
Will see how it goes I just need to carry it for a week or two and hope the added bulk is not to much to ruin the Stiletto's best virtue which I believe is it's UI which is the same as the standard so I'm good there but it will come down to does the Pro carry as easy as the standard and that is what I will be looking for or I guess I should say what I'm will be feeling for.
After opening package and playing with the Pro outside I realize the YouTube review above in this thread is a really good review and he seems pretty much spot on to how I feel. When I ordered the Pro I honestly did not believe I would be super impressed compared to my standard Stiletto and I had a bit of buyers remorse but because I ordered an extra one for a gift I did not cancel my order, I still almost cancelled them both. As soon as I took the light out of package and felt its high quality and especially after I got it outside with the smile on face I had zero buyers remorse left in me.
Right now it's probably the best light I have and folks I got many but I'm also a huge fan of the Stiletto and my story is just like the YouTube reviewer except I got my first Stilleto because a local business had them basically at half price and I could not walk away but honestly I thought it would just end up being another gimmicky light that would end up on my shelf not getting used but I bought it anyway and I just ended up not being able to leave it behind it was just to easy to carry and had a simple but useful UI anyway that's how I ended up not canceling my order for the Pro after buyers remorse and boy I'm glad I didn't.
And you just wanted to know about the low mode lol sorry I could not help but blab on.
