Its a nice light for the price, you get a high quality lanyard, comes with two switches one tactical and one reverse for tailstanding. The holster is well made and the clip is sturdy for belt use.

Cons:

  • Wish they came out with an OP reflector as an option for a much smoother beam profile.

Build Quality: ★★★★★

I gave the build of the light full stars because of the price....the S series in ITP's lineup were made for everybody, the included accessories like the reverse switch for tailstanding was a plus, since it was not mentioned on there site. The tactical switch has momentary on meaning a slight press of the switch will cause the light to come on and it has the tactile feel if you know what i mean, responsive. Another great item that they included was the holster......not a cheapy at all.

Battery Life:

L- 5lm/40hrs

M-35lm/4hrs

H-120lm/1.5hrs

Im getting this straight from there site since i have not done a runtime test of my own. Depending on the mah and quality of the battery the hours stated might not mean much. On an AW 14500 the body of the light does get warm but not hot, and it seems to gain at least 10 more lumens when compared to some of my other lights.

Light Output: ★★★★

With the Cree R2 this sucker is bright on nimh with good runtime, and if you plan on using a lith cell this sucker gets even brighter. The smooth reflector works the beam nicely which for me makes this light a small pocket thrower. You can change modes via the switch on the side of the head which is low, medium, high, and of course strobe. Unlike there C series this one has a switch to change modes instead of twisting the bezel to get the light output to ramp up or down. You can still ramp up or down with the SA1 if you hold the tiny switch down when the light is on.

Summary: ★★★★★

I will have to say get it because of the price and what gets thrown in the box, the accessories are top notch.

Beamshots as mentioned.

The sequence is from low, medium, and high.

I'd decided to stop buying lights for a while. Looks like you persuaded me to stop stopping....

I just had to get it when they first came out.......even though the light gets used once in while. Believe me when i say its worth it, i also have the SC1 which is the same light except it uses cr123 or lith rcr's. One thing good about the mode switch on the S series is that its not plagued by the half press on the ITP C9, which is something that bothered a lot of owners that bought the light, a light press to the switch and the light would go into strobe or sos depending on where the mode is. The C9 never gave me any problems when it came to mode selection though. But for the money i had to get both. They also have two AA, 2cr123 versions as well. And the good thing is there all the same price no matter which one you choose. http://www.batteryjunction.com/itp-s.html BJ is just a reference link since they carry most if not all of ITP lights.

Hey Al, thanks for the awesome review and meticulous pics! Frontpaged.

This light is definitely of interest to me. Sounds like it has a nice low mode. I will continue to keep an eye of ITP, they get consistently good reviews.

The low works pretty well......and the light can also be diffused with a water bottle cap as well. I would like another, but i want so many as it is now.....lol, very hard to keep track.

I have been using the reverse clicky a lot for its tailstanding option and with the split ring on there it would stand crooked...lol. Took a cutting wheel and cut a slot so the split ring would rest in.

Im still digging and using this light a lot, im also liking the throwy part of the light because of the smooth reflector- dont really know why i havent been using this light earlier, guess its because of all the others that i have lying around.

Hi, alfred. Great review Wink Have some questions:

- Which one is brighter: C7 or SA1? (please compare it to C7 tactical version if you have it)

- Which one of those has brighter spill? (SA1 has much bigger spill, AFAIK, but don't know if it's brighter than C7 spill)

Thanks in advance Wink

Ok, don't know where Alfred is, perhaps someone else may explain this case. Here's the SA1 and C7 beam shots (from selfbuilts review @ CPF, can't login there, don't know why). Well, frankly I don't have any lumen/lux tester, but I don't understand how SA1 can be brighter than C7 Undecided When I see this beam shots (done with 1xAA NiMH), looks like (to me) that C7 is MUCH brighter (at least the spill) then other 2 lights.

And now, Throw/Output Summary Charts:

1xAA Eneloop NiMh Throw max Lightbox MIN Lightbox MAX Ceiling bounce MAX
ITP C7 (Q5) 42 (1800 lux) 2.2 39 3.0 lux
ITP SA1 (R2) 56 (3150 lux) 7.8 52 4.1 lux

1x14500 AW protected Throw max Lightbox MIN Lightbox MAX Ceiling bounce MAX
ITP C7 (Q5) 58 (3330 lux) 2.6 62 5.7 lux
ITP SA1 (R2) 76 (5800 lux) 8.5 78 8.0 lux

The reflector seems more_narrow/deeper on the C7 ... so the important thing might be light/area vs. overall output (lightbox)...

The middle of those hotspots are saturating the camera sensor, so you can't really judge the relative brightness between them. For example, the sa1 one might be 150 in the center, and the c7 110, but if the camera sensor maxes at 100, you wouldn't know this since they're both at 100 in the pic. The sa1 also has larger area of spill.

added:

Take a look at the photo on that cpf thread after the one you posted. Even at 1/4 the exposure speed, the hotspot's saturated. Even at 1/64 the exposure, the spot are at about 20% values. That means the hotspots in the first photo are about 10 times overexposed!

That 1/1600 photo should tell you in large part why the sa1 is brighter. The hotspot is simply larger and more than makes up for any difference in the spill (kind of expected from a xp-* vs xr-* emitter).

Wait a second... maybe I have misunderstood those charts, but... "lightbox max" = "max spill area"??? Should be in inches or centimeters. Or not? Undecided

OK, I see that spill area of SA1 is larger than C7 Laughing Aham, looking at second shot, 1/100 sec., I still noticing that C7 spill is brighter. (or am i wrong?) However, C7 hotspot is smaller but better defined than SA1.

PS.: agenthex, can't see any difference in brightness looking that 1/1600 shot Undecided C7 seems to have bluish tint, thats all Undecided

lightbox max is similar to ceiling bounce, except in a much smaller box :)

You can't really say one is better defined than the other from a saturated shot (like the 1/100). Some of the xp-e lights, especially with smooth reflector, have a perfectly defined hotspot with a "halo" around it.

The last shot only shows that the sa1 spot is larger by at least 50%, and a bit brighter to my eyes. You can use the eyedropper tool in a image program to tell for sure.

Ahams. Thanks for the clarification Wink

OK, I used eyedropper tool and 1/1600 sec. beam shot. SA1 hotspot should be a little bit brighter I think. But spill is 2 o 3 times brighter on C7. Much concentrated because of smaller spill?

Thx for the help, guys Wink

If you count pixels approximately and calculate area, you should be able to do a numerical integral (ie sum). Xp-e's have more side spill, so more of the light is going to be in the hotspot areas (it's clearly larger).

Less spill is because reflector or bezel is deeper. Spill is from the light coming from the 'central' angle of the emitter.

Remember that the SA1 uses a smooth while the C7 is half and half. The spot and spill will be smaller on the C7 and the SA1 uses an R2 while the other is a Q5.

Thanks, Al. All this I know already. Could you tell me if C7 spill is brigher and how much? Without any lumen tester, etc. just how you see it with your eyes. Sometimes I see big difference in charts and so on, but later, in real life, the difference is almost inappreciable.

UPDATE: can you try them with NiMH AA batt? I need AA light mainly (but with 14500 compatibility)

The spot and spill on the SA1 is going to be a lot bigger then the spot and spill on the C7 because of its hybrid reflector. Dont get me wrong i like both lights but they should at least give us the option of reflectors for these lights.

Haha, Don. Good one !

Looks like we all suffer from the same nervous twitch...
