Very useful information there maukka, thank you!
When you’re done cleaning you can come over here…. 
i read you earlier comment, raccoon city made the 1000th post so nothing wrong with you :partying_face:
lol someone probably deleted their comment and made you the 1000th post 
Yup, you guys are definitely a bad influence.
Nah, I bet you are truly grateful.
the green look nice, i hope i dont regret buying the green one.
My green D4 with N219C’s came today.
Even with a Panasonic NCR18650B cell it still get’s hot on Turbo and starts stepping down fairly quickly. Seems to me the tube is robust enough to bore it for a 20700…. will see about that. If I kill the long tube it’s not a big deal as I like the short configuration anyway.
Has anyone installed a TA Driver in one of these? I was thinking about it to significantly improve the efficiency of the medium modes considering how high Turbo is…
You are my bad influence. Haha. Ordered one green piece after seeing your pic.
Swapped out the 5A2 XPL HI I had in one of my D4s for 3A XPL HI last night. Tint looks a very pure white, much cooler than before. Cooler even than 3D.
Might be a bit too cool for me. Next thing to try is a mix and match. Perhaps two 3A + two 5A2 or maybe three 3A + one 5A2
The green color made me buy it. A birthday present to myself. My birthday was Aug 9, so my birth stone is Peridot, which is lighter in color yes but close enough. So if I can get it outputting green light as well, the inner Green Lantern will be happy. ROFLMAO
Hello
Which holster do you recommend for this FL?
Thank you
Ordered my second D4 with XP-G2.
219c with 20700? Sounds hot.
219c with 20700 sure sounds cool, i dont know how you guys get on with 18350 or 18500’s………….I can run an 18650 down in minutes, few lasts/step downs and the cell V is 3.6v. In fact, i tested a vtc5 2600mah cell, from cold 100% stepping down/ramping till it settled . Left it for a few mins and checked the V at 3.98v. So roughly a normal use from max output.
I have 2 spare 18650’s with me now lol
Well, the Sanyo “B” cell has some 4200mAh and does around 10A, the “A” cell is around 3000mAh and does much more current. So I was thinking the high capacity B cell might be appropro
Dale I had zero doubts that this light would finally suck you right in. It’s hard to resist an awesome light, sold by Richard, tinkered on by TK, and created by Hank and Tom. That mix of ingredients leads to an awesome light any day of the year. It doesn’t matter how many of these hot rods you have cranked out over the last several years, just hard to resist when a new one with high quality and minimal price like the D4 comes within arms reach. It’s instinct really, we can’t be blamed for what nature makes us do.
10a would help control the crazy heat a little(may get another 5 seconds!) but seriously 4200mah in the tank is super useful……………i like the idea!
Now we just need to convince International Outdoors to sell us some 20700 tubes. With knurling. 
Happy belated DB
