P60 sized led drop-ins (part 3)

[schiesz]

Thank you Schiesz
I believe M30s are the best option in the market right now; however I was trying to find cheaper alternatives.
Good that you have the Solarforce D26 module coming. I will wait your feedback about brightness and primaries capability.
I wish we had some bean shots comparing the Solarforce D26 with other one cell lights ......
Regards

I've been looking for cheaper alternatives as well, but i'm starting to think that the new M30's just can't be beat. I don't know if my older M30 is the same as the newer ones because mine seems to have the same output regardless of primary or Li Ion cell used. As far as the tests, I'll have it all up for you guys as soon as the slow boat from China gets here with my Solarforce D26 module.

I also just had a cheap drop-in give out on me tonight so I rebuilt it with a DX converter for 1.5-4.2V. So far the output on this on is really good considering I think this was a Cree P2-P4, but it is drawing 1.2A off a primary compared to the 0.85A the malkoff M30 pulls. So now I just need 1-2 more drop-ins for 3V and i'll be set

Thanks kosPap
The Deerelight 3SD it is basically what I am looking (2.8-4.2V), however they mention 18650 or 17670 batteries so I am not sure if it will work fine with 123 RCRs.

Besides I thought would be nice share this with my fellow cpfer's, I didn't want promote an ebay merchant here; so please do a search for "L2+L2M DYI R2" and you will be able to find it easily.

DANG

I paid 32 bucks for the two bodies and head!!! this is some offer, you got to post it in the good deals forum...when you receive it would you mind informing if 18650 will go down the single cell tube? (I will be making a 2x18500 light using an 18650 extender)

Reafarding the derrelight module I do not see why it shouldn't work with a 16340 RCR. (I am no expert only my point seems reasonable) You get less runtime but comparative output tests with my other dereelight modules show an slight edge for the RCR.

How is the Dereelight MC-E lamp assembly as a P60 drop-in? Anyone here have one?

 

[PlayboyJoeShmoe]

Just tried 123 on a 3SD. Acted flakey but did put out some light.

3.6v makes it act right and get bright.

That's the MC-E, right? I understand it is designed for (ideally) two rechargeable cells (around 8.4v ideal?) but it sounds like it can do well with a single rechargeable, like an IMR18650 or an IMR16340?

Can you estimate how the much difference there is with the Dereelight MC-E and a single rechargeable vs. two rechargeables?

 

[PlayboyJoeShmoe]

No, mine is 3SD Q5.

I wouldn't think MC-E would be any better on a 123.

With the Lumens Factory D26-LED Special 3.6 volt

Does anybody know the actual minimum(if it has protection) and the absolute maximum voltage?

I've read elsewhere it's tuned for 3.0-3.6v, but what is the max...4.2v or 4.5v or st else?

Also could it run safely on a single primary cr123?


Edit: Word back from LF "The driver is set at 2.4 to 4.2V."

I looked real quick and didn't see this posted yet..

I made my own but this should be the highest output D26 module out there.. easily 400L out the front (if it's direct drive).

Rat... from Lighthound:

"D26-LED 3.7V Special, High Output Single Mode LED Reflector Module, Selected Tint.

(3.6V Constant Output) - Single 17670 or 18650 battery ONLY"

I would definitely use this with a 3.7v rechargeable 16340, 17670, 17500, 18500, 18650 etc. (4.2v off charger) without hesitating. When lamps are rated for 3.7v rechargeables (17670, 18650, etc.), it's known that they will be 4.2v off the charger). So a 3.7v rechargeable (when at 4.2v off the charger) should be fine... of course, if you wish, this could be confirmed by LF or LH. Also, if you use AW protected rechargeables, you will have the protection provided by the cell. It will run fine on a RCR123 (16340) but the runtime will be much shorter than with the recommended 17670 or 18650.

Superdave... that could be an awesome drop-in! Great price too. Anyone have one of these? How is ordering from KD? Reliable? Good customer service with problems?

Looks like the same module on the DX list (currently last on the list). Pitty it is not M-bin. Holding back on my MC-E P60 drop-in purchase till M-bin is available without strobe modes.

 

[outersquare]

i just want one you can run off 2 CR123s

Camping... what is the bin on the offered one? What does it look like? And what does the M bin look like?

 

[Rat6P]

Thanks DHart,

I admit I was wondering why LH doesnt say 16340's are fine. Thinking about it now my M30 pulls about 1.2A from a 16340, so this should be fine as well.

The shorter runtimes with 16340's doesnt bother me. I like the profile and they are rechargeable afterall

I still wonder what the max input allowed is though.

Camping... what is the bin on the offered one? What does it look like? And what does the M bin look like?

According to the sellers it is K bin. No visual difference between M and K bin except for light output.

Any idea what difference there would be in output?

 

[CampingLED]

Here is the link to the CREE MC-E B&L datasheet

 

[Superdave]

The one i built is using a M bin direct drive. I've ran it on a single 18650 as well as off of 2 cr123's. It is brighter on the 123's of course but it gets warm pretty quick.

If the KD one is using the same old Cree reflector used on the Q5 then it probably has a donut hole at a distance, up close it's nice.. although way too bright.

I'll see if i can post up a beamshot of mine.

 

[Superdave]

I think this shows just how bright the MC-E is...

I used my 5MP Kodak camera on auto with the flash turned off.

Here is a Surefire P60L on 2 fresh cr123's:

Here is a Cree Q5 800mA dropin

and here is the MC-E in the same Z2 host on the same 2 batteries

you can see the dark spot in the middle, but outside where it really counts this thing is nuts. :thumbsup:

 

[NigelBond]

That's an insane difference there superdave. I understand the original p60L only claims 80 lumens though. Have you got any other dropins that you could comapare it to?
