 I Upgraded My Daddy's Old Surefire 6P - Malkoff M61 LED Conversion Saw this video about 10 days ago. I have a few older SureFires. One had a burned out buld. So I ordered three.(Should of been four.) The stander 6V-P60 buld is sixty five lumens. This if I remeber right has 450 lumens!!! MALKOFF is the manufacturer. It also made in the USA! Just a heads up for anyone with an older Surefire, that they really like! PITA45

I have one in a 660 for a retro ish build, good kit and a decent thrower for what it is. One day it probably make its way to a black hawk down gun
For weapon use I would skip the cheap 15 bucks Chinese drop ins as the malkoffs are fully potted as well as having a full brass heatsink, although for just a knock around light the cheaper alternatives would probably be fine, although I would take their very high lumen ratings with some salt. There are a huge range of drop ins for 6ps with some custom builders out there making what ever you want if are willing to pay/wait  Attached File Attached File |

Malkoff may of been around. But the first I have heard of it.
Being made in the USA is a plus, at lease for me. I'm so far, quit pleased with this upgrade! Let you know in a year or so! PITA45

I have 4 6p's. Two of them have Malkoff 361Ns and the other two have Malkoff 61Ns. I'm quite satisfied with the upgraded LED modules. I've found the 361 bulb to be a great everyday task light. I also upgraded the tail switch to McClkicky switches and run 16650 rechargeable batteries in them.
There are brighter and more capable lights for the money but I like the fact that I have spare parts and can replace any part of the light that I might need too should one of them go down. |

Op is discovering something that some of us have known for a while.
Good for him! Shows an inquiring mind; Always a good thing. May I suggest we assist him, instead of berating him for being late to the party? OP, I have upgraded many Surefire lights with LEDs. All to good advantage. I have also upgraded some older lights, such as 2- and 3-cell GI flashlights with drop-in LEDs. This latter was probably not the most efficient use of my money, but I didn't want to throw them out. They still serve me well, alongside better lights. YMMV. OP, keep on investigating things, and making things better. Good for you! |

Good news is that the newer LEDS are probably better than the ones I bought long ago. Just make sure to tailor the voltage of the replacement elements to the voltage of the batts in your flashlight. I'm sure that many people here will have recommendations as to bulb replacement modules. |

Do the Malkoffs significantly change the run time using standard 123s?

Quote HistoryQuoted: Do the Malkoffs significantly change the run time using standard 123s? That would be a question for Malkoff to answer. It has been my experience that there are a multitude of LED modules available. I suggest one looks into both module brightness/longevity, and also look into the desired light color emitted by the module. Generally, the brighter the bulb/LED, the shorter the battery life. All these things are ultimately trade-offs. so do your homework in order to answer the "trade-off' questions best for your particular application. |

Quote HistoryQuoted: Do the Malkoffs significantly change the run time using standard 123s? The original 6P puts out 60 lumens for approximately 60 min. I upgraded one of my 6P’s to a Malkoff M61L that puts out 230 lumens for 5 hours before starting to taper off. With the current crop of 1000+ lumen lights that may not sound like much but it’s a very useful level of light for me, so it works. |

The p61 bulb put out 120 lumens for 15 to 20 minutes. Both could be found in old school 6p's |

If you are unsure about which part to buy, you can email Gene Malkoff with a picture of your light and he will make some suggestions.

Malkoff's very useful M61LL is cited as 10+ hours at an also very useful 100 lumens, from just 6 volts (2 CR123's) ... If you have a Surefire 9P or add a battery extension on to a 6P or similar sized body, plan on that run time figure going up another 5 hours.   |

@creature,
Yup! An FM65 red filter, although I also have some FM66 (Blue) covers, a FM64 (white diffuser), and a FM67 opaque cover. The only filter in that series that isn't as useful as intended is the IR FM63, because the LED doesn't produce any IR light. Those filters fit on a 1.47" diameter bezel, and will also fit the Malkoff MDM4 SureFire Millennium Adapter bezel you have on your M961 series light. |

I bought a blue cover from you a year ago last month. I've been looking for a FM65 red filter for ages with zero luck. |

I killed alot of pigs and coyotes with my old g2z.
No need to upgrade in my opinion because anything brighter is just to bright and washes out everything. Did I make it in before that crowd? I have several old surefires I need to upgrade and get them into the usable level. Hell my edc has 160x the output of my old surefires that were the shit back in the day. |

I have a 6P that I got during the Lowe’s 50% off sale and even modding it with a 3 mode 500mA P60 and protected 17670s, it’s an archaic piece of shit that sits in a drawer.

Go sell it on ee or something if you don't want it then.
I have some sorta newer stuff, while bought new I don't chase newest stuff due to the big price difference for some improvement in performance. I have several old surefires, some are some old weapon lights from police departments that got sold as surplus last year. Still looking at em debating what I want to do with them. Most stuff that is made so you can replace the bulb and work on it can be upgraded as well. From the old maglights to surefire to some other odds and ends I am sure. May not really be worth it. Depends on how you value things. |

Not enough blinky modes for you? Not enough buttons to play with? It doesn’t throw 2000 lumens for a 1000 yards? If it doesn’t do what you need it to do, maybe you just bought the wrong light. |

Back in 2011, it was an 80LM LED light that cost $75 plus tax and that was so far behind the times that it wasn’t even funny. And I spent an extra $75 just to make it slightly better with the Redilast 3-mode drop in and 2 Redilast 17670s. At least one could get a MagLite for under $25. Hell, my dinky Fenix P1D puts out substantially more light (50% more light) and it fits on a keychain and has 3 modes. Chris |

Take your old 6ps and wrap some sand paper around a large drill bit to hone it out inside. Run rechargable 18650 instead of 123as. Did that to both of my NRA 6ps years ago. Still keep one on my nightstand.

Still keep one on my nightstand. 16650's slip right in, no drilling, boring, or sanding necessary. They're a good compromise between 18650 and 123s. They are rechargeable, have longer life than 123's but shorter than 18650's; hence the compromise. |

I revamped some old lights, of various types, as long as the flashlight was of otherwise excellent quality; other flashlights were given away. Unless the flashlight is of sentimental value, well-made, or highly useful, re-lamping is seldom cost-effective, unless it can be done fairly inexpensively. Re-lamping old incan Sure
Fires is more-or-less a no-brainer. Re-lamping a GI angle-neck flashlight might be on the border of what is reasonable. YMMV. |
