Immersed my several month old S2+ host into 1 foot of water for about 30 minutes and had substantial leakage at both ends of body tube. Tailcap threads have a lot of up and down play when tailcap is not fully tightened. O-ring seals on both ends don’t feel very snug. Lens and tailcap seals seemed fine.
Is this typical of S2+ hosts?
Gonna try replacing the stock O-rings with larger ones from p60 hosts.
If this is still in host form, did you tighten the pill enough to snug the reflector and lens up against the o-ring? What about the switch…is the retaining ring tight?
Stock o-rings don’t feel tight enough so I always change them with thicker (bigger?) ones…
OTOH S2 has two grooves for o-rings and should be more suitable for underwater usage.
I expect it is. Waterproof is a relative term. Even IPX-8 is meaningless without the depth rating that is supposed to accompany it. Barely submerged the light might be fine but a foot of water is a foot of water, not an inch, and not held in your hand on a rainy day. A $15 host and some new o-rings isn’t a bad way to improve the rating /$.
Thanks all. Will report back after I get them swapped out.
Incidentally, I think the tail end double O-rings on my 6ps all have misteriously shrunk. The lights sit around the house, out of the sun, and are used only occasionally, so minimal cell change. They’ve stopped passing the 1.5ft deep for 30 mins immersion test. They used to. Their lubed with Super Lube.
Tailcap O-rings for 6ps are just a bit too thick and too stiff, but found a couple that provide a very snug fit.
1-foot submersion for 1 hour, bone dry.
I think Convoy should consider adding a retaining ring that clamps down on the switch boot and thicker O-rings on both ends of the body tube to increase the performance and value of this host.
I think most non-dive lights are designed to be water resistant. For instance they should be resistant to rain, dropping them in a puddle, quick immersion in water, etc. All of my lights meet that and that’s all I really expect them to do.
30 minutes in 1 foot of water puts those lights into a different category and price point in my opinion.
The switch retainer already puts pressure on the switch boot as does the pill on the lens o-ring. If the switch retainer seats without enough pressure you could either use a thicker switch disc or shim the stock one with something as simple as tape to be able to increase the pressure on the boot. The depth of the milling where the switch sits can vary slightly, sometimes causing the rubber actuator in the boot to preload the switch giving it a too sensitive feather trigger or other times not sealing well. Similar problems in the heads of some other lights can prevent the retainer from fully snugging the driver leading to unreliable grounding. I figure it’s all part of “budget” flashlights as I don’t want to pay more to get something glued together.
Again, didn’t expect it to be. All my IPX-8 rated lights pass the 1 foot 1 hour immersion with no problems; they’re not underwater lights either. Didn’t expect the S2+ to be IPX-8, as it is not advertised as being so.
All my IPX-8 lights can stay submerged in 1 foot of water for more than 1 hour.
As I posted above, the S2+ is able to do it as well.
All it took was replacing the stock O-rings with a couple of slightly thicker O-rings.
I don’t see how that would place the S2+ in a different category and price point.
Thanks for the insights.
If the addition of a separate retaining ring for the boot requires substantial more work and commands a higher price, then I agree that
it’s not needed. The current design, per my test, seems adequate. Knowing that the boot seal doesn’t have to rely on the switch retaining ring being tight, it being reverse threaded notwithstanding, brings peace of mind.
The retaining ring in the tail serves two purposes, to clamp the ground ring of the switch pcb and also to sandwich the boot against its tail cap seat but the two seats are separated but the switch and the spacer. I’ve noticed a bit of variation both in the stand off height of the switch and in the thickness of the aluminum spacer discs located between the switch and the boot which led me to suggest an adjustment there could improve the seal and/or fine tune a temperamental switch.
Sometimes it seems a topic like this can get beat to death but it takes awhile for word to get around. Possibly any reiterating that it’s not a dive light haven’t read every post, I know I tend to skip to the end sometimes.
