    PERFECT ! been a long time a customer of led torch shop and have bought a variety of torch’s over the years . can confidently say the Klarus XT21X Pro is well worth the price. Bright! size is great, beam distance and spread is perfect. i use this for security and has been the best torch i’ve owned for it.

    Bloody bright torch and comfortable size
    Prompt delivery

    This is my third Klarus torch. When looking for a new torch I immediately thought of getting another Klarus. My other main Klarus (XT30R) is bullet proof. I was in the man hole of my ceiling space in the garage and accidentally dropped my XT30R from about three meters straight onto concrete. I saw it almost in slow motion as I waited for it to but in to a thousand pieces.

    It landed lens down into the concrete. To my utter surprise it just bounced a few times and came to a stop. Still works perfectly fine. Damn was I impressed!

    This unit is more compact and extremely bright. Doesn’t have the same throw distance as the XT30R but awesome out to about 200-250 meters.

    Highly recommend. Unless you loose one you don’t ever really need to buy a replacement, just add new ones to the collection.

    This light is fantastic. As a building inspector I rely heavily on my torches and this is the best in my arsenal. I highly recommend it!

  5. Jamie Urquhart (verified owner)

    Awesome light just what I needed to stay safe working all hrs of the night in dodgy areas.
    So bright I wouldn’t want to be on the other side and hope not to use it in self defence.

  6. Nick Goodwin (verified owner)

    Prior owner of Klarus products and suitably impressed by this latest offering. Own its forbear the XT11GT, a great torch in its own right. However, its progeny raises the bar still further. Quality build, outstanding illumination in both the throw and flood aspects. Simple controls with versatility and range of options. In addition, easy to use, compact, robust, typically generous inclusion of multiple extras especially the thoughtful choice to provide an adapter for 18650 batteries of which I have many from other purchases. How more could you want from such a versatile, durable and eminently reliable product? Well done Klarus.

  7. Apostolos Cerasiotis (verified owner)

    Impressive torch. Functionality and power. I am a night security guard and need to light up areas differently depending on the sites. Amazing. Also, easy to use and power up.

  8. Dave (verified owner)

    Great touch, had the earlier model for years.

  9. lachlan blackburn (verified owner)

    great product!! ive had to use it while working and works a treat!

  10. Vicky (verified owner)

    OMG is this torch bright. It works brighter than the lights in my house.
    I brought two, one for me for when the power goes off and one for hubby for work. So impressed with the brightness, the amount of light it throws, the number of different settings and it actually feels nice to hold.
    Brilliant product, very happy.

  11. Nick Hossack (verified owner)

    This is an incredible light. I’m surprised how easy it is to use and I’m also surprised by the power of the light beam. I get up at 4am and take my dog for a walk. I just use the button at the end as I need light. I also feel very comfortable that the strobe comes on in one easy touch.
