I "lock" all my button lights by unscrewing the head by about half a turn. Haven't tried it with a CX3, so make sure the o-ring is far from being exposed.

I just tested that and I believe it is not an option.

The tail cap is spring loaded and the light stays on even after unscrewing the tail cap pretty darn far.

Bummer. I was really hoping that would be a workable solution.

I really don't see it as that big of an issue. I've been diving with push-button lights for years and years, some kept in a pocket even. I've had them turn on accidentally maybe 2-3 times. But I am only doing recreational diving, with no penetration (wrecks nor caves), so my light is a tool but not a necessity to complete a dive. Those where it is a necessity (night diving), I have two lights plus it would be very obvious if my light turned on accidentally. YMMV. If you dive full DIR with backup lights on your harness and tucked with an inner tube, the pushbutton is more of an issue.

I dive with a CX2 attached to my harness with inner tube. after over 100 dives I have never had it accidently turn on

I have seen with my own eyes the inside of someone's luggage that was melted from having a light turn on accidentally inside the luggage.

I've had the CX3 turn on accidentally 2 or 3 times in one week of 21 dives.

"It has overheat protection."

"Mine has never turned on accidentally."

"My light is not a necessity to complete a dive."

All well and good. But, none of that changes my desire for a way to lock my CX3 off.

None of that changes my mistrust of it turning on by accident and what *could* (possibly) happen as a result.

It's a great light. I will keep it and use it and do my best to ensure I don't have a serious problem.

But, it would be an even BETTER light if it had a 100% reliable way to ensure it stays turned off (in the water and out).

I hear you. Your priorities are different than mine. It’s that simple. Your desire to have a way to protect or inactivate the button is equal to my disinterest in having said feature. :wink:

Would that feature be a negative for you? Or you just don't care about it at all?

It could be a negative. Depends upon how it is implemented. If it makes it difficult or cumbersome to turn the light on for example, or is unduly bulky. Otherwise it would make no difference to me. I certainly wouldn’t upgrade to a new version to have the feature.
 
Any updates on FX40? Curious how divers find that light in caves. I've been getting mixed feedback.

The switch takes a little getting used to since there is no tactile feedback. Once you get used to it though it is easy to use and it is nice not having to turn it off to change modes. It is slightly smaller than its predecessor (LX20) with a slightly tighter and more well defined spot. Color temp is also more blue compared to the LX20. Weight is basically the same; the FX40 weights about 0.6oz more at 1.24lbs (without handmount). Charging is more convenient than the LX20 but it is more difficult, but not impossible, to change cells which can be an issue if you are planning to do multiple dives a day. On Turbo it is significantly brighter than a LX20, High is basically equivalent to a LX20 but delivers ~105min more run time.
 
I just picked up a FX40 as a travel light, intended as a replacement for an ancient Light Monkey 12W canister.

On 'high', it seems a bit brighter than the LM overall, with a much brighter/tighter spot and comparable burn time, while being half the size and weight - and the LM is already pretty tiny. Having the alternative light levels is nice - 'turbo' is clearly brighter than the LM; 'medium' is a bit less bright, but then has double the run time. I'll probably leave it on high most of the time.

The switch is easy enough to get used to. I'll probably make up a little sleeve to go over it for travel; even though it seems not particularly likely to turn on by accident, in a plane over the ocean, you want that risk to be zero. I like the USB_C charging, reducing travel size and weight even more.

Potential negative is the corona is narrower than the LM, and more defined, there is basically no light cast outside of it. Initial impression is of a loss of peripheral vision - in a white environment with light bouncing around it should be OK, but in dark cave I can see it feeling quite tunnel-vision-y. Will have to see how it goes getting used to that.
