    Even Zebralight SC600fD III+ (more mass, more efficient driver+LED) can't do 1500 lumens handheld, they level out at about 600ish lumens.

One reviewer on BLF tested it and after 30 seconds on VTC6 it had stepped down to something like 300 lumens, but on an Aspire 18350 it had only stepped down to 1400 lumens. Basically the extra heat from the 18650 caused the temp sensor to kick in faster and overdo it.

    On the upside, due to the ramping it's very easy to ramp back up if the temp sensor brought output down too far. My guess is the light can probably do 1500 lumens sustained for an extended period of time if you handhold it, and perhaps do not start at max turbo.

    Slippery grip
    Do you carry this light in a pocket, but hate the lack of knurling? ... simple solution is to add something to improve the grip. I installed Talon Grip Tape from Amazon on mine. Adds very little bulk and turns a slippery light into my grippiest. Feels great in the hand too. I highly recommend it for this light.

    Its been in pocket at work and at home when carried yes, if i had a clip option but tapped for it............would be a winner(not into clip on clips at all). Thats a great idea with grip tape, it is a slipy feel/body...........but still nice to hold in hand.

    Yes step down is aggressive but the head heat is still almost too much to bare (fine holding body but i like to get a better idea of the heat before i trust the step downs). Now even with the aggressive step downs, it is still toasty before it settles to a lower output and brings the temp under more control.

    Cell used will sure make a difference, i have tried a vtc6 and 30Q only, if I used a 10a cell.....................probably hold out a bit longer. I have found though with even larger 18650 lights, 1000lm is too much to ask after 2 or 3mins, even 600lm is too much after 10m or so. Even a HDS 200lm gets quite warm after 10 + mins.

    But i accepted before i got the D4 its not about running it for any length of time at full output, more for super short blasts and use the lower ouputs for actual general uses. I have said before, i can pretty much live with 200lm or less(most uses at work are around 150 as one example). At home, at night 20 or 30lm will do...............more is always fun though

    Off to check some grip tape! cheers

    Thanks for the pics, that actually looks really good! more importantly with an actual use. I only have the 18650 tube, for two reasons really. Just not enough in the tank with an 18350(even the aspire.......heck it does not take long to eat through an 18650!) ,also the 18650 is compact enough for me with this light. I have some 18500's sat around which may tempt me to try one of those bodies(don't have an 18500 light). Iirc they are just 1000mah......for the sake of 15mm or so , I can have 3 times the run time(roughly).

    +1 on the Talon Grips. I have a couple of lights with it installed and will likely put some on this hot rod when it comes in the mail too.

    I need to get some but the price is insane in Canada for talon grip (at least on Amazon).

    Here in the U.S. it cost me $11 plus tax for a 5" by 7" sheet ... enough tape to put grips on a probably a dozen D4s. Free shipping with prime.

    I think a sheet would cost me $46 and tax.

    Would there be any benefit for performing a spring bypass at the MCPCB and tailcap?

    I don't think this puppy can be driven any harder than it is. The FET driver is pulling everything the battery can give it as I understand.

    Not really. The light already uses some very high quality low-resistance springs. Same springs as on the Noctigon M43 I think. Also there isn't a lot of extra room in the battery compartment. The springs squish almost flat, making a spring bypass iffy. Finally, the light already gets hot very fast. Even if a spring bypass were to increase current all it would do is make the light heat up even faster while providing no noticeable increase to output.

    Damn that green looks good Re-219 flavours, i have quite a few 219b's from 4000k and I to love the slight rosy tint. I do like this 219c 5000k , on my sample its a pure white and colours look accurate to my eyes. Its nice to have a few choices, kind of break up the LED's,colour temps and tints............just keeps things fresh imo.

    Little pic of little lights i took ready for tonight(nothing special actually happening, just my lights to use and play with)


    Its crazy how fast it sups mah from the poor 30Q's..........i have another 30Q and vtc5 ready to swap out. This can be minutes of use...............Defo need a spare cell or 2 ready

    Loving mine. Had to increase the temperature setting as I like to run my lights between 600 to 1000 lumens and it was dropping below 600 lumens after a short time of use.

    I like to run my lights around 600 degrees (F, not C-- I'm not crazy!)

    Seriously, I love my Nichia version, and I love it even more with a slightly more floody optic I just got from mtn electronics.

    Did that optic smooth out the squarish beam pattern?

    Yep, it's a smooth wall of very nice Nichia light, with no evidence of pointy bits.

    Nice triple tixx

    Where are you guys looking, 219c here, i was hedgehog hunting last night and just a wall of light, could not see any artifacts at all. Hot spot pretty much blended into the spill at 10ft or so. Before that a very soft hot spot at say 5ft, colours looked great and accurate. If i shine it above an object by around 4"(just tried it) then yes square and can just make out the optic legs. Obviously i would not use it like this though. Other optics also give artifacts close up, usually when almost up against something.

    You're correct ven, the only place you see beam artifacts is close up. I like the more diffuse optics to slightly smooth out the hot spot to Corona transition. I tend to prefer floody, especially when it is that bright.

    I bet those hedgehogs were impressed with your little D4!

    Could not find it again, rach was armed with a predator prov2.5 warm as well. Earlier the kids had found it and it went into long grass near the pond . They were waiting for it to come out for ages, then decided to check and it had moved. The kids made a right mess at the bottom of the garden building a home for it

    Other than the frosted quad, all have artifacts close up. Luckily my uses are for more than a few inch away. Although I do check beams close up or against a wall , it's what's outiside that matters to me(or what I see in use which could also be inside). Frosted certainly soften the beam out, I like it a lot. But don't feel the need to convert my other quads. In fact I like them the way they are.

    Its amazing how fugly some beams are close up, but in use perfectly fine or unnoticeable for artifacts.

    Thanks Ven!

    There is also the XP-L issue where it makes pointies around the large hot spot. I guess the angle of the LEDs can be changed with this to correct: http://www.mtnelectronics.com/index....product_id=849

    Thanks for all the useful and interesting information on this light, I just had to order a Nichia version what I am still confused is what battery and rating would be the best compromise to run this setup I have a hard time understanding what I need between High current vs Big reserve ? What are you all running in your lights.

    Having had all D4 lights at 5000k or below, here is my tint preference

    Iíve had every one of them and here is my list from best to worst according to my eyes and Iíve had multiples of them, not just one of each:

    1) XP-G2 4000k
    2) XP-G2 5000k
    3) XP-L 5000k
    4) Nichia 219c 5000k

    I have my 18650 collection down to two flavors, one flat top for Zebralight compatibility, and one button top. INR18650MJ1 (green, button top, 10A): ~3200 mAh to 3V; and, NCR18650GA (red, flat top, 10A): ~3250 mAh to 3V. Vinh recommends the INR18650MJ1's for some of his high current lights, and Zebralight recommends the NCR18650GA's--that's good enough for the girls I go with. Both cells work well for me in the D4. I think mtn electronics has a list of 18650's broken down for "high capacity" and "high current" in the D4 listing, so I know there are lots of other options.
