Stellar upgrade for "hotwires" fans!
"The Malkoff M61WL is a fantastic dropin, especially for fans of 'hotwires' (ie incandescent bulbs). It was designed to mimic the tint and color temperature of an incan, and I have to say it comes pretty close. I installed this dropin in a Surefire 6P. Just for comparison I put the old incan back into my 2nd 6P to compare them. The results were illuminating (if you'll pardon the pun). The tint is very close! The Surefire incan bulb is slightly more yellow/orange than the Malkoff but the difference is subtle. The biggest difference is the beam quality; the M61WL is much better. Both of my Surefire incan bulbs have egg shaped throws with lots of artifacts, along with a tight hotspot with very little spill. In contrast the Malkoff dropin has a very smooth, round and large spot with a very good amount of spill. The spot is just a little larger than the spot of the incan but the spill is vastly larger, and quite uniform. Of course, the LED runs a lot cooler, and a lot longer. With the incan they claim an hour of runtime but in reality the output drops precipitously after about 15 minutes. The incan also gets very hot. The M61WL runs a lot cooler; the entire head is a heavy brass heat sink. I haven't tested the runtime of this particular dropin but I have other Malkoff 'L' heads and they run for around five hours before they begin to drop out of regulation. The Malkoff light engine is a lot more durable, too. The Surefire incan bulbs are prone to breaking if dropped. But you could use the light as a hammer with the Malkoff dropin installed! The tint/color temp is really great! It's warmer than a Nichia 219B , Malkoff M61N or Elzetta Alpha or AVS head, although a little cooler than an actual incan. But unless you compared it head to head with the incan you could mistake it for one. All in all a great dropin! I tend to prefer the neutral lights over the warmer ones for appearance and for max output. But this one has me thinking of trying an M61W. Highly recommended! This is a great dropin for someone that likes the quality/tint of incan but wants to get the durability and long runtime of an LED."
