NEW Foursevens Quark MKIII Aspheric Lens Kit

#tight

The Quark Aspheric Lens Kit is HERE.⁠

I've been working on this in the background for over a year. The aspheric lens kit allows you to convert your Quark from a reflector-based light to an aspheric-based light. The white Delrin reflector (machined in-house) helps generate some spill, allowing you to see nearby surroundings while throwing a ton of light down range. ⁠This is the tightest beam you can get in a package this small.

Note: This kit will work with older Quarks (non MKIII) if you can manage to separate the head. They are glued shut and can be difficult (or nearly impossible) to remove.⁠

$50 for a AAA clicky light? I dunno. I’m possibly warming up to it though. Just a quick question. Does this particular 219C have that horrible green tint that I notice on all other 5000K 219C’s? I like 5000K but haven’t seen a 219C yet that looks good at that temp. 4000K looks phenomenal though.

Are you talking about the Preon P1? Mine has a little green tint on the low mode, but at higher modes it is pretty much a neutral white. Unfortunately I don’t have any other 5000K flashlights to compare to. I usually go for 4000K.

Yes, I guess that would have helped if I had mentioned that I was talking about the Preon.

I have been buying more and more 4000k emitters to put in some lights and I now lean towards that temp when thinking about buying a new one.

Thank you.

That aspheric setup is nice. :slight_smile:
But have you considered making an aspheric flooder? Myself I love that smooth flood with sharp edges. And I love the compactness as well.

BTW, is there a new Quark Mini AA on the horizon?

Next-Gen Quark MKIII

A Classic, Re-born

Like an old friend

Continuing the Quark legacy was always a priority for Prometheus. Since our acquisition of the Foursevens brand in 2018, we've been toiling away in the off-hours and weekends until we arrived at an iteration that walked the line between honoring the past and pushing forward into the future...with a hefty sprinkling of Prometheus dust thrown in for good measure.

Reliable, dependable, comfortable in the hand and pocket – the new Quark was never going to be the brightest LED flashlight on the market. That's okay. It just needed to be the rightest LED flashlight in your collection.

To kick off the Holiday season we're taking 15% OFF the two new Quark MKIIIs. Just use discount code HOLIDAYME15 at checkout.

In addition to the two new Quark MKIII lights, we've released a handful of new Quark accessories so you can tweak and tinker to your heart's delight. Scroll down to check those out. They're all also 15% OFF using the discount code above.

NEW Foursevens Quark MKIII Aspheric Lens Kit

Mod squad

The Aspheric lens kit for the Quark was another project being worked on almost in conjunction with the new Quark itself. Full respect to the custom flashlight crowd – aspherics are fun as balls.

Although the Quark aspheric is fairly small, it generates a cone that increases the maximum throw by about 30m (from 170m to 200m).

The magic here is in the hexagon-shaped LED die of the Nichia 319A. Where normal square LEDs project a square beam, the hexagon shape is round enough that the beam feels natural and allows for 100% focus. Learn more about the Aspheric in the Install video below.

Quark Tailstand Cap

Most people prefer a "forward" clicky switch that supports momentary activation. However, the "tactical" forward clicky switch sits proud and you can't tailstand the light. If you did want to tailstand, you had to swap in a new switch and boot...the problem being the short switch is a "reverse" clicky and you can't use momentary mode. Problem solved!

I have yet to meet a Quark (excluding the Quark Smart) that doesn't accept the new tailstand cap, which is designed to snap on easily and can be removed using a small, flat screwdriver.

Backward Compatible.

Forward Thinking.

It's a poorly kept secret that I obsess about pocket clips. I've owned many a flashlight over the years and found too many included clips to be wholly inadequate. So I set a high bar and went for it. Today we design and manufacture a number of high-end titanium aftermarket clips for other lights. After acquiring Foursevens it was a mission to apply that same standard to designing a pocket clip just for Foursevens lights.

These clips are backward compatible with various earlier Foursevens lights and even include a Quark Deep Carry option. Made from heat treated stainless steel, all clips are designed to deliver: reliable, durable, good retention, smooth pocket engagement, and not damaging to your clothing.

Did I mention they're also 15% OFF for a limited time??? Use discount code HOLIDAYME15 at checkout.

5th Gen FTW

Xtar's newest generation of multi chargers do not disappoint. Independent channels means you can charge any battery chemistry (ahem – Quark owners). The VC2S (left) can also act as a powerbank to charge your other devices (phone, etc.) via the USB-out port.

The Xtar shows you how charged your battery is AND estimates the time to full charge. This is my go-to brand of battery charger and I'm pretty stoked to stock their latest iteration.

A couple things to be aware of:

  • We will NOT be getting any new Nickel or Copper Preon P1/P2 lights in the foreseeable future, so if you've been eyeing one but holding back, now is the time to act!
  • The Patch Hats (360 Headlamp Compatible) are currently on pre-order and as such not on sale. Sorry to disappoint...but that shouldn't stop you from pre-ordering if you fancy a stylish solution to attaching your headlamp to your hat.

Beta or Bust

Award-winning pocket stuffer

Every year the Beta QRv2 is a Holiday best seller. Why? You got me, you'd have to ask everyone who gifted it. If I was to guess, I'd say it's because:

  • AAA battery (convenient)
  • Quick release feature (baller)
  • Three mode (considerate)

All Betas except for the Titanium are 15% OFF through the Holidays.

Betas covered under the discount include:

Weird Flex But Okay

Obviously got swept up in the Holiday Spirit and applied the 15% OFF discount to the Beta Flex Arm AND all Beta Flex Arm Bundles, which includes the Beta Black or Beta Brass Flashlight.

This is a nice gift for that someone in your life who could use a hands-free, magnetic, articulating light source. I use these all around the shop and have sold many to mechanics, woodworkers, tinkerers, and craftspersons who need a little extra illumination around the work area.

Kappa Quick Release Keychain Organizer

Some gifts are no-brainers. Got a friend or loved one with a keychain? Kappa QR them! Boom. Done.

The Kappa Quick Release Keychain Organizer is my answer to the jumbled mess that can become a keychain laden with keys, keyfobs, flashlights, bottle openers, rubber chickens (for real) and anything that can loop around a key ring.

Comes in Nickel, Brass, Copper, Titanium, Delrin, Lexan varieties.

I would love to carry a mini turbo in my keychain but there is no way for attachment. Any ideas?

Also, do you plan to offer more emitter choices other than NW XPL HI?
