Malkoff Devices M61 LED UpgradeThe Malkoff M61 P60-style drop-in LED upgrade fits SureFire 6P, 6Z, C2, and G2 flashlights as well as the Malkoff MD2 and Elzetta ZFL-M60 lights. A solid brass body acts as a heat sink for optimal heat dissipation so you do not need to worry about your flashlight overheating. The orange peel reflector has been designed to give a balance of throw and spill.The M61 is made to run in lights using two CR123A batteries and operates with regulation within 3.4-9V. When the voltage falls below 3.4V, the light will run in direct drive. The bright output will blind anyone within a 100 foot radius or illuminate objects up to 350 feet away.The M61 is available in a few different varieties. All versions are made in the United States with the same rugged, durable build-quality. The two main differences between the models are: the tint of the LED (either standard or neutral white), and the output/runtime. Models with lower output (and greater runtime) are indicated by an 'L'. The neutral white tint versions are denoted by a "W". This version is the M61, with the greatest brightness of 450 lumens but lowest runtime of about 2 hours.A fitting ring is required if used with a shock-absorbing head (ie M2). An M61 Lens, or suitable equivalent, is required for use in the Malkoff MD2 and Elzetta flashlights.Note: This mod will not work in Wolf Eyes Lights.WARNING: This light is capable of causing eye damage at close range. Please use the light responsibly!!!Note: This drop-in module was intended to operate at maximum brightness for tactical usage similar to the original setup. Operating the unit for more than 15 continuous minutes in plastic lights may cause damage to the drop-in module. This is not an issue in metal lights or in plastic lights with a metal head.

"This works great, brought my early 90's surefire dedicated into this century."
"My 16 year old Surefire Z2 is now my favorite light again! I had it milled to fit a 18650 power source and with this M61 drop in, it is as bright as the 500 lumen options from Surefire and Streamlight. Works with cr123's as well, couldn't be happier with purchase. Thank you, Gene."
"I put away my old favorite Surefire 6Z some years ago after I got tired of replacing the sadly shock sensitive OEM head. At the time a good LED upgrade was just too expensive to justify. For a sale price of 54. 95, the 325 lumen Malkoff M61 P60 looked like just what I've been looking for. It was. The transaction was painless, the shipping timely, and the performance has been excellent. Nice bright center, and enough flood around the outside to light up the rest of the room. My old friend is back in the EDC lineup."
"Works great in a custom light I built for my son. He uses it for night shrimping trips to the Florida Keys. Bright and great thermal management from massive heat sink."
"Ths is a great drop in head. I did have an issue with it, but it's most likely my fault. I had a light with a KX4 head (supposed to be the recoil version) to soften the blow from weapon mounted lights. However when I purchased the light it was advertized as a weapon light and was built a little different (like it had an xtra spring), it wasn't the same as the other style lights (it did drop right into the older textured 6P SureFire light. Again it works, and works well and worked in my older light, not sure if they changed the KX4's now vs the older ones, but it didn't work out in my case. I'm not as good as the guys on Candle power who can do anything with these, but this unit is built out of heavy brass, potted electronics and is bright."
