The runtime is longer because the higher the volts the less amps used to make a lumen. The amps increase as the voltage drops.
My 18650 hound dog has now been running on low for 248 hours! On 2 alkalines. Give or take an hour or so.still very usable an is WAY brighter then any moonlight mode. Can read very easily with it and will still throw 10-12 feet across my room. This thing is amazing 😉
Disassemble all parts, clean all the gunk out, swap out those o rings, and use a quality lube. Looks like east Texas is rough on tools!
I prefer cooler temps for throwers, and warmer temps for up close. Seriously considering a E series throw head from malkoff. Hmmmm.
Where do you think the M91 fits into this, do you prefer the coolest option for that one, or neutral?That is my preference.
I keep it simple: I go cool when I want max performance. I go warm when I don't need max performance.

Cooler Temps are definitely more eye straining. That is why on most phones you can use things like eye comfort shield which lowers the blue light and makes the screen warmer. I have mine on about in the middle of the slider and it helps a lot.not strictly related to the HD super, but recent weeks I have noticed that if I use a light for several hours straight, with a warmer color temperature I get snow blindness* much later when looking at very similarly colored surfaces
* I know snow blindness is officially when you get eye damage due to UV, I meant it in the way when you look at a snowy surface for too long and the contrast just goes, same as looking at a body of water for an extended period of time and stuff just tend to blend into each other
I've been running my HD super for a while with 3 x 18650s and am thinking of going back to 2 x 18650s.
Has anyone done pro/con testing? I'm just thinking the batteries might last a while longer with 2 along with the light being easier to pocket.
Thanks for all the advice. I used 220 grit sandpaper on the aluminum (lightly), acetone/q-tips on the brass and cleaned all threads. Then I used Trident diver's grease (100% silicon) and lightly lubricated the o-rings and threads. All is good now.
ledbetter, yes we had a big storm here and I was out in the rain for several hours. It's interesting to note that all the EMT / fire rescue guys did great work but all had lights that were dead in an hour or less. My 3 x 18650 hound dog super didn't miss a beat. However, I did use a headlamp the whole time and used battery discipline with the hound dog.
Overall the hound dog is a fantastic light that's gotten me through many tough situations/storms and I can't say enough good things about it.
I tried to provide a link but currently the website is down. The company is Overready and the SKU is C5-OG-EXT70-IIIB (Custom 18650 Extender - Type III HA Black).Hi,
What did you use to extend the MD4 body to house 3x18650's?
