Nailbender, Ehlo, Flashfiend (and everyone else),

Thanks for the extra info and sharing your experiences.

I had no idea heat (or dissipation of) was such an important factor in the lumen output.

I tried running my 3mode SST-90 on 1xAW IMR 13640.
Seems to do well for 1-2 minute bouts (I was worried about things melting to try much longer).
Not quite as bright as 1x18650 but still a very very smooth and bright flood for under 10cm.

My clamp multimeter should arrive tomorrow so hoping to do some more testing and measuring.

I just found this thread today:
http://www.candlepowerforums.com/vb/showthread.php?t=257443

Now that's a real beauty!

I thought of just taping 3x SST90 (in identical 18650 hosts) flashlights together, 🙂
I can unscrew the switches and set up a single switch.
Maybe then stick the whole thing inside a bigger host :naughty:
just an idea (maybe a stupid one)

eventually I'll see the light!

I would have done, if I knew. 🙂 You do test them both in the same host the same way and use both without or with the same outer spring? Maybe the SST-90 has some contact problems, or maybe it got hot enough at some point to melt the solder that makes between the board an the brass section of the drop-into making that connection worse.
Current draw of both should rise as they become hot. Thinking about that, maybe insufficient cooling is also a factor to the high readings some people get. :thinking:

That is an interesting thought elho. The host I am using for the sst-90 is an FM D36 1x26650 and it does have seating depth issues for the module as contact with the middle seems minimal (battery travel with light assembled is only a few millimeters). I still wish I could test my setup with a single-mode direct drive sst-90 to check against my 3-mode. As for insufficient cooling that could also be true for other people.

Has the heat from the led and or from tightening head to tight deformed the middle spring.

If the solder had melted he would not have a connection probably at all. Plus only a lite tap would make the light turn on and off. Please don't bang the heck out of it to try.

The board may be bad but I have had less than a 1% failure rate other than heat problems that was not a defect and I have used many many of them.

Feel free to send to be checked if you think it bad.

Dave, the middle spring looks good unlike my 1-mode sst-50 in which the middle spring and tailcap spring have deformed. The module still functions however and I think I have found ways for that module to pull a constant 3 to 4 amps depending on my battery setup [size and voltage (for protected 17670 or 18650) or voltage (for IMR 26650)].
------------------------

I guess I will need to ask around for other people's current draws with an IMR 26650 and 1-mode sst-90.

Deformed tailcap spring= not good! :shakehead
 
Re: XPG modules plus SST-50 -90 & MCE/P7 P60 dropin Modules for Sf product (part 4)

Which host's tailcap? BTW, the only time I ever overheated a tailcap spring was due to a short, not overcurrent.
 
Re: XPG modules plus SST-50 -90 & MCE/P7 P60 dropin Modules for Sf product (part 4)

Does that have a McClicky, or something you installed yourself?
 
Re: XPG modules plus SST-50 -90 & MCE/P7 P60 dropin Modules for Sf product (part 4)

If the spring is deformed, there's a good chance the contacts inside have been compromised; did the spring turn blueish? If so, it might be a good idea to replace the switch. I'm not sure how many amps McClickies are rated for, but a quick search should tell you.

And BTW, if the contacts are burned/pitted, that could account for your fluctuating meter readings; was the fluctuation after the spring deformed?
 
Re: XPG modules plus SST-50 -90 & MCE/P7 P60 dropin Modules for Sf product (part 4)

Actually, It's the host with the good switch with the fluctuating readings. The one with the bad spring is actually pretty consistent. Though I may replace it still.

Hey, I'm only trying to help.
 
Re: XPG modules plus SST-50 -90 & MCE/P7 P60 dropin Modules for Sf product (part 4)

Hi Dave,

Will your SST-50 drop in fit into fivemega's Deep Turbo head? If you have tried it out, does it tighten up the beam a good deal? Almost ready to pull the trigger on that as well, but just need someone elses opinion.

Thanks!

HI

yes the D26 works well and is one of my favorite heads. I use it alot along with the D36 heads of his.

It does in my opinion tighten the beam up, I know some did not think so but in my opinion I could tell and immediate difference.

I also think it helps with heat as it is a large piece of metal.

To me it is great. There may be a small gap try not to over tighten, most of the time mine close all the way just don't force, trim the spring if needed and have fun.

If you feel that the head tightens up the beam of the 50, then that is good enough for me. Hopefully, I'll get lucky and get one that fits!

Thanks for the response!
 
Re: XPG modules plus SST-50 -90 & MCE/P7 P60 dropin Modules for Sf product (part 4)

Which of you drop-ins, if any, would you suggest to mate with an FM Deep Turbo C head, SureFire 6P (stock, unbored and thus capable only of 1x17670 max), and SF twisty tailcap? I saw your positive comments regarding an MC-E drop-in with the Deep Turbo C. How much hot spot lux increase does the FM head produce? Is the beam quality otherwise unaffected or does it get ringy?

If the 1x17670 power source is a limitation, I can switch to an FM 6P clone body for 1x18650 capability.

Thanks.

Hi Dave,

What would you suggest for a a good thrower + runtime in a Solarforce L2 host running a 18650? Can you do a multi-level 1.4A driver?

Thanks!

Hi
The MCE doesn't have rings but it will have a muted 4 leaf clover in the middle. Any quad will still have that. I don't have any numbers for lux increase but to my eye I can see a reduction in width of beam and to me a longer throw. Maybe not scientific but I do see alot of beams and have certain distance points I use for reference and I see a difference.

I know you like fairly nice beams so even with a 17670 for power I think a SST 50 does well in the turbo C head adn is a contender. The 90 even though a single die has some slight clutter in the middle that is not noticed in the 50 and no rings with the fifty. That is if you are looking for a super bright.

I think the XPG and warm diamond dragon I just tried also look good in it with few if any rings.

An 18650 give more run time but I dont' see it as any better choice other than that.

Hi

It depends on what you are looking for in a thrower. The XRE and XPE are narrower viewing angles so it will be a tighter hotspot.
The XPG has a wider hotspot but to me it throws as far although many don't think that.
To me the XPG is a good choice.

Yes I can do a 3-level 1.4 amp. it is 6 volt max.

The 3 level with a 8.4 volt rating is also a good one as it seems to hit a sweet spot with the XPG. I get good lumen count out of it. It is high / low / strobe though.
It does have memory so the strobe is not a big problem. The low is quite low.

Hi Dave,
Sorry, I meant to ask about the possibility of a single level, regulated dropin at 1.4A. Not a 3 speed version.

With regards to the type of beam, I'm looking for, in order of importance, 1) longest throwing spot 2) most lumens given the 1.4A drive 3) good beam characteristics in case I'm pressed into using the light for short range stuff.

Seems like the XR-E R2 will give the best throw, but the XP-G wins in the output department. Need to search for some beamshots.

Thanks!
