    Well, you can still do that with the L head on a 1xAA body. You just won't have NiMH or alkaline capability.

    The only thing I'm a little confused about is running 1xCR123 primary cells. If I read correctly, that should be safe on either head. For that matter, so should 2xAA NiMH, although that one may be a little on the low side for the voltage of the L head.

    I, too, would appreciate more info on running one CR123 with the L head. I asked about this earlier in this thread and was told no, won't work, but what I have read elsewhere seems to indicate it should work. Any more comments on this?

    On the Prometheus/QK16L page, the voltage range is listed as 2.8V - 8.4V. I don't why any body/battery combination within that range wouldn't work.

    The standard CR123s are a no no. Most do not have the ability to safely deliver the current needed on Burst. The "L" head will work using a HD RCR123 cell. Foursevens offers such a cell if You want to lego the L head to a Quark single 123 tube, it's a go. Oh, and if your light is pre sursuit, you'll have tailcap lockout with it also.

    I'm sure G_L? knows what he's talking about.

    I was just L@@King at the voltage range. I also didn't think 700 lumens would be too much for a CR123 to handle given the amount of time Burst mode would be operating before the step-down.

    Meanwhile, back at the KICKSTARTER page, the new Quarks have received $66,000 in pledges. That's a lot of Quarks!

    Does that also apply to using 2xCR123's?

    2-CR123A's will work in the "L" head, but it is not recommended. Having two cells could become unknowingly mis-matched can cause an unsafe condition. I would use them only as a backup. The watt hour capacity of the 16650 is greater than the capacity of two cr123s. The "L" MKIII's are designed for use with one Rechargeable Li-Lion cell to avoid an unbalance, and save the landfills from spent primary cells. (2)RCR123's have about 2/3's the capacity of the one 16650. In the likelihood You are planning on using disposable CR123s, please be sure both cells are from the same lot from safety reasons.

    causing thermal runaway in the other
    cell. There is a significant risk of fire
    and/or explosion when using two cells.

    Thank you.

    Previous Quark's runtimes were based on 2xCR123's.

    What would the estimated runtimes be for the new Quark using 2xCR123's?

    Iím from the old school where when I use 2 rechargeable cells (be they Ni-MH or Li-ion) in any device, those cells have always been used together as a pair their entire lives. As a rule I will not take one of the AAs out of a 2xAA light and use one of them alone in another light only to recharge them and then put them back in a 2xAA light. They get discharged together, and they are recharged together. Another thing I just wonít do is use a battery charger that charges cells in pairs on one charge circuit. So if for any reason one cell is at 70% and the other is at 85%, once the cell that started at 85% reaches 100% and peaks, the charger will have to decide to either stop, in which case one cell is at 100% and the other is at 85%, or it keeps going, and one cell gets overcharged while the other approaches itís peak. I will only use chargers that have an independent charge circuit for each individual cell.

    The lumen per watt has increased with the MKIII series upgraded driver/LED. Your runtimes might not be significantly different, but your usable available light on Medium has increased from the previous Legacy lights. The MKIII "L" series buck drivers are more than just an LED swap/upgrade. They are matched for the Nichia 319A LED which has less luminous flux than the previous Cree LED's, but much better color recognition and better efficiency at less than maximum output.

    I'm with you... I want to replace my AA Quark and get a 18650/16650 but I often find myself using a true medium level. Medium here seems too bright... maybe when Mark III v2 comes out?



    By the way, what am I missing here? So many people excited about this lights. CRI is not special by today's measurements, neither is run time nor brightness.

    Sure I love my Quarks (from over a decade ago), but what is "special" here? Is it the Led. Honestly I'm curious.

    I got excited by the possibilities with the new Quark, since I have six quarks these could lego with. But the lack of a setting between 10-50 lumens (~30 preferred) was a deal breaker for me as well, since that range by far is my most used level.

    Yes, Yes, and Yes.
    The LED is ~>+80 CRI, the 219C bin used is very near Neutral White, the Quark MKIII driver now has multiple UI groups to choose from, the shift to single lion cell power
    and 1 or 2 cell NiMh power, and the introduction of having both Tactical and Tail standing right out of the box.

    Me too, GL?s. One of each. I wasn't going to let such a good deal go by, on the first new & improved Quarks, from the new owner. Am I not a fanboy?!

    Will the new Quarks be the perfect EDC for everyone? No. There's no such flashlight, nor will there ever be.

    Thank you for making our project a reality!

    A few things need to happen before we can kick off fulfillment.
    Here's a quick rundown:


    • First: Kickstarter needs two weeks (from the campaign close) to collect and transfer the campaign funds, and follow up with any Backers with credit card issues. Kickstarter calls this the "quiet period" but we'll be full speed ahead.
    • Second: we have to find out and where we need to ship your rewards and if you want to add any extra items. Weíll send out a BackerKit survey to collect this information when the quiet period ends.
    • Third: We've used BackerKit to manage all our previous Kickstarter projects. It's easy, secure, and makes sure we get you the right rewards as fast as possible. We love it and you will too.


    Survey = Pledge Confirmation + Add on Items
    *** Right now we are planning to send surveys on September 3rd,*** but weíll give you a heads-up 24 hours before so that you can watch for it. You donít need to create a BackerKit account to answer your survey. The invitation email contains a link to your personal survey. It is important to submit your responses as quickly as you can since we need this information to process your rewards. We can't ship your rewards if we don't know where to send them

    You'll also be able to pledge for additional "add-on" items like additional Quark lights, Quark accessories, batteries/chargers, and other Foursevens lights!
    Making Changes to Your Pledge
    If you need to change your survey responses, modify add-on items, or update your shipping information, you can click the link in your survey email again or request your survey link under "Lost your survey?" on our BackerKit project page. (
    This page will only start working after we send the surveys out.
    )
    If you prefer, you can contact me directly and give me your information, but answering your survey help us get your rewards out to you faster. BackerKit helps us save lots of time by streamlining the survey process, automating data organization, and providing us with pledge management software to make it easy to process your pledge reward shipments.
    Basically if you ask us to take your shipping info over email, we are working on email instead of shipping rewards. You will not be able to add any extra items if you opt out of BackerKit.
    We will email the survey based on the information below:


    • We will send the confirmation email to the address you have registered on your Kickstarter account.
    • If you used your Facebook credentials to log in to your Kickstarter account, the BackerKit survey link is sent to the email address you use for your Facebook account.



    Again, thanks for all your support. We canít wait to send your rewards!

    Cheers,
    Jason & the Prometheus Team

    Update #5

    BackerKit Surveys Going Out This Week!


    Posted by Foursevens
    September 3, 2019

    Creator
    Hey Backers! Hope everyone is well.
    Surveys will go out some time this week!
    Today is the last day of the "quiet period" required by Kickstarter. We are ready to send out surveys pending the funds transfer. The quiet period ensures all of the pledges are processed and gives people time to resolve any credit card issues. If there was a CC problem, Kickstarter will have contacted you over the last two weeks.

    Next Steps:


    Once we verify the funds, surveys will go out to a small subset of backers. This is to ensure we didn't forget anything in the setup process and to make sure everything is clear. Once we get a certain amount of feedback (and verify our setup) we'll send out 100% of the surveys. The lag time shouldn't be more than a day or two.

    I'm clarifying this point because people will start commenting that they got their survey and others will comment they have not. This is part of the process to ensure you are just as happy with your backer experience as the final product

    The Survey:


    We use BackerKit to collect your shipping info an to confirm your Kickstarter pledge. You'll also be able to view and pledge for "add on" items via the survey. We are friends with the folks over at BackerKit and we've used them to fulfill/manage all of our 6 previous campaigns. You will not receive a Kickstarter survey. I only point this out for folks who have backed other projects that did not use BackerKit to manage their fulfillment.

    Using BackerKit is not a requirement, but it makes our life (and yours) a lot easier. Please consider that if we need to collect your pledge confirmation manually, we are spending time doing email and not getting shipments out the door I and your fellow backers thank you for your cooperation!

    Cheers,
    Jason and the Prometheus Team
