I bought a Preon P1 just to try it out. After using it for a while, I began to really appreciate it. It has three modes L-M-H and 2 hidden modes, beacon and SOS. I am running this light with a blue colored unprotected 10440. The stock clip sucks so I ordered one a custom to one from Promethium Lights. It was expensive, so it better be good. It hasn’t arrived yet. I also ordered a clickly tail switch from Unique Titanium. It arrived today and I installed it. It works great! I am so in love with this light, I ordered another. I will upgrade the second Preon as well. I am just waiting for the clip to arrive to see how good it is. 
If anyone knows where to get a good replacement clip that’s cheaper and better than stock, please reply.
I too have a Preon P1, I’ve been using it as a keychain light since I bought it. I only just tried using my P2 body and clicky tail for work today. I must agree the stock clip is quite poor. It grips the shirt well in terms of not being worried about losing it when I lean forward which for me is a big part of my job but it does take two hands to secure it back in a chest pocket. Post your experience with the new clip and pics if possible.
I sure will! I like the smaller length and using the unprotected blue 10440 Li-ion batteries and the clicky tailcap, but yes, the stock clip is terrible. I usually have it clipped to my front left jeans pocket and I have occasionally “lost” it. Most of the time it has dropped into my pocket, but a couple times it fell off in a friend’s car, another time at home when I was changing into my house clothes. For $20, I’m hoping that that new Ti clip is worth it. It is being sent by USPS, shipped on 3-4-14. Today is the 7th. It’s coming from South Carolina and it looks like it just left the sort facility today and in transit, which I guess means Monday or Tuesday… 
It’s the waiting that’s the hard part.
Sidenote:
I also have a Streamlight Microstream C4 that I run a unprotected blue 10440 Li-ion battery in it. Extremely good flashlight, but only single mode. I don’t run it longer than a minute or so with the 10440. The clip is excellent on it. I think I will swap it out for a NiMH instead. It’s extremely bright.
Update:
The 10440 is better than the NiMH battery on the Streamlight Microstream C4. Once you use an 10440, it’s difficult to use a lower output battery. Maybe someone has a mod for the head to keep it cool to run for 5 or 10 minutes, or maybe a different tailcap with some kind of circuitry that will do the 3 mode L-M-H and two secret mode thing.
I too hated the stock Preon clip - so much that I never took any of my lights outside for fear
of losing them.
Then 6 months ago I ordered 2 darksucks(Prometheus) clips. If you order 2 you might get free shipping
like I did.
Since getting those clips I carry my P1 everywhere I go, even to bed.
It’s either clipped in frt. shirt pocket or to my shirt collar.
If using my P2, that’s always clipped to rt. frt. pants pocket.
I never worry any more about losing my Preons!
I’m glad that you are having a good experience with those clips. I like hearing good user experiences. It makes me feel good that I took the leap and bought one.
I would be really sad if I lost my Preon P1 now, especially after putting a clicky switch tailcap on it, and especially at this moment in time, while I’m waiting for the Ti Prometheus clip to arrive. I don’t think most people realize that the clip is a real important issue for folks who pocket carry their lights.
I need to get another clip for my second Preon, but recently I have ordered an Peak Eiger Ultra flashlight. It hasn’t arrived yet either. I want to get a momentary tail switch and a clip for the Peak Eiger Ultra, so maybe I’ll get free shipping when I order a clip for both. (I think for $35 or $40 you get free shipping.)
The problem I hear for the Peak Eiger Ultra is the momentary tail switch for the Peak Eiger Ultra isn’t as good as before, that the plunger is a bit too short now for the newer version of the lights. There’s a couple sites that sell them, one of course is oveready, but I’ll have to investigate this issue further. I’ll post another topic for that one.
Today my Prometheus Lights Ti Clip for the Preon P1 arrived.
It was sent in a nice plastic square tube in a padded envelope.
I installed the clip on my Preon P1 which has the clicky tailcap switch.
Here it is side by side with a regular Preon P1. Both have the blue unprotected 10440 Li-ion battery in them.
I noticed something that people should be aware of. With the stock clip and the clicky tailcap switch, you can use either the tailcap switch or twist the head to turn on the light and to switch between the modes.
Notes:
When you install the Prometheus Lights Ti Clip, you lose the ability to only use the twisty head or only use the clicky tailcap separately to activate the light and the modes. After I added the Ti clip, you need to first click the tailcap to turn on the light, then use the twisty head to adjust modes.
I believe this is caused by the tiny extra distance that the Ti clip’s thickness adds between the switch and the battery.
Since I primarily just use the clicky tail cap to switch between the modes, I don’t consider it too much of a loss, but still I want to figure out a way to use both.
I will go down to the machine shop some time this week to see if the folks down there would give me a piece of sheet metal. If I can find a thin, playing card thickness of maybe copper or aluminum sheet metal that I can put between the spring of the tailcap switch and the battery, I think that would work. I’m thinking of using a paper hole punch to see if that is strong enough to cut a disc out of the sheet metal and check the size. The disc should be slightly smaller than the diameter of the battery so it can be removed easily and yet stay in place and not move around in the body of the flashlight. I have a pair of Cutco kitchen shears (the one that can cut a penny in half) at home if the paper punch trick doesn’t work.
Hints:
I used a post it note and wrapped the body of the flashlight before screwing on the clip and the tailcap switch to prevent any chance of scratching the surface. A piece of paper and some scotch tape would work too. The new clip is substantially stronger and thicker, and slightly longer than the stock clip. Also don’t forget to take the rubber o-ring off the tailcap clicky before putting on the clip, and then put the o-ring back on once the clip is installed.
This week I will see how good the new clip works out. Hopefully I won’t lose it. Now that I installed a clicky tailcap and a clip that costs as much as the flashlight itself, this flashlight has become an investment. Once I figure out a good way to make the tailcap clicky and the head twisty and the Ti clip all work together, I’ll put up another post.
Today is Sunday. This week, another clicky tailcap for the other Preon P1 should arrive.
I don’t think I’m reading you post right.
“After I added the Ti clip, *you need to first click the tailcap to turn on the light, then use the twisty head to adjust modes. *I believe this is caused by the tiny extra distance that the Ti clip’s thickness adds between the switch and the battery.

Could you clarify the operation with this new clip.
I have to verify this when I put the clicky cap and the stock clip on my other Preon P1.
When I added the Ti Clip to my Preon P1 with the clicky tail cap, the twisty did not seem to work anymore.
In other words, I can not initially turn on the flashlight with just the twisty only, when I have both the clicky tailcap and the Ti Clip installed.
However, I found that if I first turn the flashlight on with the clicky tailcap, then I can cycle through the modes with the twisty again.
You can still turn on the flashlight and cycle through the modes with just the clicky tailcap switch.
I hope this clarifies things…
So far, the Ti clip in terms of holding ability is pretty good. Way better than the stock clip. The flashlight did not come off in my pocket or fall out when I sat down.
At lunch, my leg started inching.
Then it started burning a little bit.
Then it started burning even more.
At the time I did not realize what was happening, then it dawned on me. The light is on high in my pocket!
I reached down and pulled out my light. Yep, it was on full high mode. It was pretty hot, so I turned it off.
Nothing bad seemed to happen to it. I tested it later after it cooled down and it was fine.
I loosed the head so it would not accidentally power on from the tailcap clicky getting accidentally pushed.
So another question pops into mind.
How to mod the switch so that it is not sticking up and easily pushed?
I have no problems cycling through the modes on my titanium P1 with DarkSucks clip and clicky tail.
BTW, that container that the clip came in doubles as a 18650 or 2X CR123 carrier.
With the tailcap clicky and the Ti clip installed, I can cycle through all the modes as well. That’s not a problem.
The problem is the change in operation.
What I can not do anymore is ONLY using the twisty head.
I have to turn on the light with the clicky tailcap first, then I can use the twisty head to cycle thru the modes.
OR
I can cycle through the modes just using the clicky tail cap.
Before the Ti clip was installed, with the stock clip I thought I could do both.
That’s why I think it is a distance issue. I will verify on my other Preon P1 when the other clicky tailcap arrives.
That is a great idea for using the plastic container that the clip came in. Love it! Thanks!
Okay, let’s clarify this. With the clicky switch on the OFF position, you’re not going to get any light no matter how much twisting you do to the head. Likewise, loosening the head by more than a quarter turn will disable the light and nothing you do with the tail cap will turn the light on. It’s when you have both the head tight and the tail cap in the on position that you get light. All of this is independent of whether or not there’s a clip installed on the light.
I completely understand now.
The clicky tailcap is basically just an on-off switch.
The clicky tailcap has to be clicked to the on position for the twisty head to work.
The on - off pulses causes the flashlight to cycle through the modes.
For some reason, all of this didn’t make sense initially.
When I came home today, one of the packages contained the other clicky tailcap so I installed it on the other Preon P1. I can verify that there is NO problem using the Ti clip.
It was just my brain farting and I am ashamed of the stank.
After playing around with a Velano Designs Quantum DD and the QTC, I got all confused.
I did figure out how to keep from accidentally clicking the tailcap to the on position.
I unscrewed the very top part of the clicky tailcap and just removed the plastic dome.
Now the top of the button is level with the top of the tailcap.
I hope that works. I’ll post a couple of pictures soon.
Thanks everyone!
Oh right, sad thing is I have my P2 in a shirt pocket for work this week with my clicky tail cap and even though I just installed it I completely forgot the twisty doesn’t turn it on.
Yes, I didn’t expect that change in usage too!
Click once to turn the light on, then you can use the twisty.
You get used to it pretty fast.
This is a small modification to the tailcap. After experiencing “hot pocket”, I wanted to figure out how NOT to accidentally turn on the Preon P1 from accidental clicky tailcap button presses when it is sitting in my front left jeans pocket.
So this is what I did. On the tailcap clicky the top ring can be removed by unscrewing it. When you do that, you can remove the plastic dome and sticks up from the clicky tailcap. Then screw the ring back on. Now the button is flush or slightly lower than the clicky tailcap housing. You have to stick your finger in a little to press the button, but it isn’t difficult.
Here is a pic:
The one on the left has the clicky cap mod and the Ti clip.
There are two problems with removing the rubber boot under the button. The first is that it’s your water seal. It’s not an issue if you don’t use the light in wet conditions, but, you will get water in the light if you do. The second issue is that the button is now recessed and a lot more difficult to reach with your finger. Someone with a lathe can funnel the end of the retaining ring to make it reachable without exposing the button more.
Thanks for the reply. I won’t be using it wet conditions so I’m not too worried about it. Luckily, the way I hold the light, it isn’t difficult for me to press the button.
However, to improve it, what I might try doing is to cut a piece of rubber sheeting into a circle and glue it inside the top of the ring so it looks like a flat surface. This should protect it from any liquids from getting into the switch. I’ll try that out sometime later and post a pic here.
But for now, I’m pretty stoked with my light!
Oh, and the Prometheus Ti Clip, albeit expensive, is totally worth it for the Preon P1. It’s a great clip, far superior than the stock clip. It is easy to slide on because it is smooth, and holds well because of the perfect amount of tension. Excellent and I recommend it as a good upgrade from my experiences.
Thanks for the review on the clips. I’ll wait and see where my Preon ends up. I’ve had it for about 6 months and it was only used as a keychain light. You always have your keys with you when you go out so I’d always have at least 1 light with me.
That sounds good! I’m pretty happy with my Preon P1 now. So far it’s been one of my favorites.
