A great light for the price, with excellent quality workmanship
December 9, 2014
I just acquired one of these lights (actually two, with a 3rd on backorder, because I'm going to give it as a gift, or, more accurately, I'm going to give ONE as a gift and keep two for myself).
First, Klarus quality is, imho, excellent. I've not found anything wrong with any of their lights, and I now own 4. The ST30 is, for the class it's in, a very slim light which could be carried in a (deep) pocket. That being said, I wish it came with a holster. I have mine in a Nite Ize LHS-03 Holster which doesn't provide complete protection for the light, but will hold it and can be clipped onto things (like a bag or belt). There are other lights which are in near, but higher price brackets which [slightly] surpass this light in beam concentration and brightness, even though their lumen numbers might be lower (real life vs. paper specs), such as the Nitecore MT40.
There is a comparison video on YT https://www.youtube.com/watch?v=Z-P2aZjHcGk (youtubeDOTcomwatch?v=Z-P2aZjHcGk) by virtuovoice which compares the Klarus ST30, the Nitecore MT40, and a smaller Eagle Tac light. All three are good, and, for the price, I'd still take the Klarus ST30 because it is a lot of light for the money. The fellow in the video gripes about the ST30's deep reflector. Well, again, imho, they did that to get the diameter down to make the light slimmer and easier to carry. I think they succeeded. Most design elements have a trade-off in some way. He also states the Klarus has no memory. That is false, it does. You can set it to some be turned off/on by either switch, and with the side switch, you can configure it to come on in any of the 4 brightness modes.
It is also a versatile light as it can use either the rechargeable 18650 batteries, or CR123A's. This light has a tripod socket. There are some camera lanyards that attach to a tripod socket, or at least there used to be, so maybe one of those might suit for a lanyard for this light too, if substantial enough and if you keep it tightened to you don't drop your light.
For those folks who don't like to read directions, you will want to read the directions on how to set the modes in this light. Once you understand and practice it, you will like it because, as I said, you won't have to unnecessarily cycle through the levels to get what you want immediately.
Now, one very important note: This light does not have a tailcap. I, being one of those who don't like to, at least immediately, read directions, spent about 4 minutes twisting with my bare hands (thank got I didn't get silly and grab pliers) trying to remove the tailcap that wasn't there. This light comes apart in the middle, with the battery compartment separating from the head. That's where you put the batteries in. Read your directions, and enjoy this great light. It will, as I saw written somewhere, show the night who's boss...
Pros:Less expensive alternative
Slim compared to others in class
Versatility of using 18650's or CR123A's
Can be set up to come on in any of the power levels without having to cycle through levels
Innovative lanyard ring which rotates
Cons:No holster, and hard to find one that would fit this light
Lanyard ring doesn't look very substantial, but no problems actually encountered
Complexity of mode control might baffle some people - not a simple light
There are lights in this class with slightly better beams and power - may cost more though
Lanyard which is included is not very substantial where it connects to the ring
