Q: Why are you always out of stock?

A: There are only two of us running this show – all the designing, machining, anodizing, and assembly is done in house by us. We only make a limited number of flashlights at a time, and they sell quickly. Be sure to sign up for the in-stock notification so you won’t miss out!

Q: I bought a Fraz Labs flashlight off another individual, does the warranty transfer?

A: We don’t care where you got the light, it’s covered. We also offer a general tune-up service for those of you buying one used; if you can get it to us, we will restore it and send it back to you totally free of charge.

Q: How many lumens are your flashlights?

A:  While we’ve not had our current models officially tested, our original model, the Qzark, was rated at 1100 lumens back in 2015.

Q: Do I need to use protected / unprotected cells?

A: It shouldn’t matter at all, but battery length may cause damage in older models. Please consult original listings for each light model for answers on exact battery dimensions.

QT and Lumenite II series flashlights have the option of using an extended tailcap which accommodates the extra 5mm added on to most protected cells. We offer two tools ( available, both as a paid print or a free download) that will help dial in the perfect battery height, as shown in the video below.

Q: What is ‘Smart Material’?

A: This is the stuff that drives the brightness change and replaces the electronics/PCB used in most lights. Originally developed as QTC (quantum tunneling composite), it reacts with pressure to achieve the variable brightness in our piston-based flashlight engine. This material is now called ‘smart material’ or ‘conductive rubber’ and can be obtained from several different sources. It’s easy to replace in our lights, and each purchase comes with extra pieces. The light will also default to direct drive or “ON” in the case of the smart material being completely destroyed or absent. Please flip the piece of smart material over before totally replacing it, this acts as a reset and will restore normal ramping function.

Any smart material (also called conductive rubber, smart rubber, or Quantum Tunneling Composite) can be used in all FrazLabs flashlights, but some types work better than others.

Q: How do I remove the ‘Smart Material’?

A: Just remove the bezel, smack it against something firmly, and find the brass piston. The smart material is held onto the end with a magnet, and will look like a black piece of material.
