    Discharge curves for AW LiCO and IMR 18500s?

    I've done some searching, but can't find discharge graphs for AW LiCO and IMR 18500 batteries. There's plenty on 18650s, but not much on their little brothers. My reason for asking is that I have a Malkoff Wildcat V1 that I'm running on an MD3 body. I currently have IMR 18500s, but I need to...

    When to Chuck an old Li-ion Cell?

    I've read on various threads that Li-ion cells are to be discarded/recycled when they no longer hold 80% of their original capacity. My question is, how do I test this? I have a hobby charger with a discharge function. A what level of discharge should I use to determine whether the cell is...

    Wattage of Streamlight TL-3 bulb?

    I recently picked up an FM E-series socket, and I'm getting into T1.5 bulbs. I've searched and searched, and I can't find any information on the wattage of the Streamlight TL-3 bulb. Also, besides the Carley options, are there any other T1.5 bulbs I should consider? I'm already looking to...

    Carley cl-43

    Does anybody know where I can get some Carley CL-43 bulbs? I have a regulated Mag623 running at 15.5v, and the CL-43 appears to be a perfect understudy for a LOLA. I know these were custom made for Fivemega, but he appears out. Is there another source? -John

    CR123A Failure Modes?

    I'm having a friend of mine here on the forums build me a battery vampire. I intend to use a single 5mm LED in a P60-type LA to run a single CR123A primary. Question: Is there any danger in running down a single CR123A primary all the way to down to zero voltage? This would be at extremely...

    Recommend Best High Discharge Nimh AA

    I've been reading about high-discharge Nimh AA batteries, but I'm a bit confused. Can you guys help me out? I ended up with a 9AA>3D battery holder, and I want to make a Mag85 for a non-flashaholic friend. I would like high performance, so I'm looking at high-discharge Nimh AAs for the...

    P61 on 1xIMR18650 or 1xIMR26500?

    One thing that Mdocod mentioned on the rechargeable G2 thread is that SF lamps are spec'd much below the nominal voltage of 123 cells due to the voltage sag of these cells under load. So a P60 is like a ~5.0v lamp, and a P90 is a ~7.5v lamp, etc. HOLA are even lower spec'd, since the sag of 123...

    Will Malkoff come out with an M31?

    Looking at the input voltages for the new Malkoff M61, it appears that it's regulated from 3.4-9.0v. The old M30 appeared to drop out of regulation below 3.3v. Does the new M61 remove the need for an M31, since it stays in regulation at so low a voltage? Will Malkoff come out with a 1.0-5.5v...

    Did Malkoff go down a design hole with the MD2 and VME heads?

    First off, I'm a huge Malkoff fan. I count 7 of them in my house right now, not counting others that have come and gone. However, when the MD2 came out, I saw that Malkoff went with the smaller window on the front of the head. I read here on the forums that in tests, the light output was the...

    Issues in powering a Malkoff M30 with one RCR123?

    I'm putting together a lego pocket rocket out of an Aleph 1x16340 body, a VME head, a Malkoff M30, and an Aleph switch with an McE2S switch. Since I'm using an M30, I would like to have full output, which requires using a 3.7v Li-Ion battery. Using a primary 123 cell will reduce output to ~160...

    Where/How do I get my Zebralight repaired?

    My zebralight H30 stopped working. It's clearly an out-of-warranty situation. My 2 year old daughter found the light and put it in her mouth, probably for a good bit of time before my wife discovered it. The babyspit completely soaked the switch area, initially causing it to cycle through the...

    Help! I need a quick answer! Almost had a protected AW 18650 go up on me!

    Hi. I need a quick answer. Tonight I almost had an AW protected 18650 go up on me. I was working on a PVC pipe adaptor to fit 2 18650s in a 2D cell mag. I had made the adaptor, slid the two AW 18650s in it, and it was sitting there with the tailcap OFF for about 20 minutes while I was...

    Will I blow myself up doing this? Please check my math

    I am running a WA 1185 bulb in a surefire M6, powered by a Fivemega 3x17670 battery holder. I was using AW 17670, but these were probably thrown out at work by the cleaning people (my fault for leaving them in the wrong spot). I have a fresh set of ultrafire 17670s. Can I use these to power a...

    Electrical Path/Resistance Question

    I've read on other threads that adding cell extensions to a flashlight body raises the resistance of the circuit, making it less efficient. Apparently the joint between the cell extensions is a gap in the circuit. My question is, how much resistance is added to the circuit? How much...

    Zebralight H30-Q5 Update?

    I'm about to pull the trigger and get a Zebralight H30-Q5. Reading a bunch of threads about it, it seems like the AA version, the H50, is about to get an upgrade. Does anyone know if the CR123a version, the H30, is going to get one, too? I'd rather wait if there's a new version about to come...

    How much is a Surefire L1 worth?

    I bid on a Surefire L1 on eBay. It was advertised as the current Cree version, but when it arrived, I see that it's the previous Luxeon version. I'm bummed. I've emailed the seller, and I'm waiting to see if anything happens. In the meantime, how much is a new in package luxeon L1 worth...

    Where can I find a Leef BigLeef Tailcap Switch?

    I guess I'm late to the party, but reading around here, I've discovered the BigLeef system, and it seems to fit exactly what I want. So, cruising over to lighthound, I see they have BigLeef necks and bodies, but no tailcap switches! They don't have any idea when they'll get more switches...

    Reaming a Surefire 6p to take 18650s?

    I've tried searching, but to no avail. I'm trying to find someone with a lathe (and enough experience) to bore/ream out my Surefire 6p to take an 18650. Can someone point me the way? Also, how much does this usually cost? Thanks! -John

    Latest LED technology question...

    Reading this forum in depth, and pouring over flashlight specs and reviews, it's very clear that the latest generation of LEDs have made a large leap over the previous generation. You see the fenix TK11, Malkoff M60, and Eagletac T10C all running 230+ lumens for 90+ minutes on 2 primaries, or...

    For the money, does anything beat a Malkoff + G2?

    This is a serious question. For the money, does anything beat a Malkoff + G2 combination? Because if there is, I want to buy it. The Malkoffs appear to be the brightest and mose efficient LED modules out there. You have the choice of 235 lumens (actual) for 1.5 hours on two primaries, or...
