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.

Save 15% OFF the Aspheric Lens Kit using discount code HOLIDAYME15 at checkout.

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.

Save 15% OFF the Quark Tailstand Cap using discount code HOLIDAYME15 at checkout.

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.

Happy Holidays everyone, and thank you for supporting a maker and the whole team here at Prometheus Lights. We are grateful for this amazing community of loyal customers and patrons.

15% OFF All Foursevens Products

Over the hills we go

All means all. We're slapping the 15% OFF discount on every Foursevens product in the store: Minis, Preons, Quarks – you name it, it's discounted.

Use discount code HOLIDAYME15 at checkout to save on Foursevens gifts

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.

Use discount code HOLIDAYME15 at checkout to save.

Betas covered under the discount include:

Side note: This is your LAST CHANCE to own a dual-mode Beta Black – as of the next shipment coming in they will all be three-mode moving forward.

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?

They are on the radar. Go to the Mini’s prototype page and sign up for notifications.

Bought these from the Kickstarter. Tested them with the Texas Ace Lumen Tube calibrated with Maukka lights and Sekonic C-800-U.

4Sevens Quark MKIII QK16L M 87 lumens 5115K 0.0027 DUV 85.5 CRI 26.8 R9 61.7 R12 83 Rf 96 Rg included battery


The QK2A has a 24 lumen mode that I somehow landed on but is not easily repeatable. Maybe just an unintentional easter egg in the driver.

The default config on those lights seems to not include the low mode. You would need to change to config 4, 5, or 6 which does include the low mode.

Low(Moonlight) should be around ~1lm

You guys make all of this possible, so I wanted to let you know how much I appreciate your support over all these years. My sincere thanks!

Would you consider sharing the campaign with your friends and family?

I can also guarantee that you know at least one person with ears, and they will thank you later ;)

Thanks in advance!

I have images in the post. Try kickstarter link to read or the web site here.

Edit: I've corrected the problem with the link in the post, Thanks for the headsup.

Hi Everyone,
Just a little heads up.
Foursevens has located some new unsold MKII Quark bodies.
They are up on the site.
First come first served. Once they are gone, they are gone.

19% OFF DISCOUNT...BECAUSE COVID19

Not even joking

This thing.

As I write this, all of California is under "stay-at-home" orders. I know many of you are in similar circumstance. I don't know what the other side of this thing looks like, but I feel very confident that we'll get there sooner than later if we stick together, stay in touch, and look out for one another.

As you can imagine, things are quiet at the shop. We've put a temporary stop to warranty claims, the crew is safe at home, and thought we're still taking orders online I can't guarantee fast turnaround on shipment. Heck, I can't guarantee what's going to happen to the business, given the general uncertainty over the length of this thing.

This thing.

That said, we will stay open throughout and ship when and how we can.

We're also running a 19% OFF promotion on ALL BETA FLASHLIGHTS* and ALL FOURSEVENS LIGHTS.

You want the discount code? Here it is:

COVID19

Thumbing our noses at this thing while putting product into the hands of our people. Can't stop won't stop. Use that code at checkout and save 19%.

It might not seem like the right time to be making a flashlight purchase. That's okay. Totally get it. To be honest I have no idea what to expect over the coming weeks. Low sales? No sales? Guess time will tell.

On the other hand if you need a good emergency flashlight or a good backup to your emergency, maybe this deal comes at the right time. If it helps give you and your family even an ounce of peace of mind, I'll feel better for it.

I also encourage every one of you to seek out ways to support local and small businesses. This bailout package is NOT going to ensure they all open at the end of this thing. Because no one knows when the end will be.

Buy a gift card.

Do takeout from the restaurant that is still open.

Find a way to help. This country is run on the backs of small businesses and it is clear that they only way they have a chance of making it will be if their communities support them.

The 19% OFF is effective immediately, no set end date. Sorta like COVID19.

If there's anything I can do to help any of you during this time, please don't hesitate to reach out. You've been here for us through all the good times – we're here for you during the bad.

30% OFF RECHARGEABLE BATTERIES & CHARGER

As if you needed another reason to love rechargeable batteries...

Many of you are (rightfully) thinking of emergency kits, stocking up on essentials, etc. Batteries should be on everyone's list. But stocking up on disposables does NOT cut down on trips to the store.

Rechargeables do.

I've marked this Battery & Charger Bundle down 30% so you all can stock up. Basically you're getting it at cost – I'm not making money on it.

Choose between AA or AAA. Get them charged right away, and store them in a labeled container so you know which are charged and which are not.

Introducing the Titanium Preon P1 MKIII

Pre-Order Store is LIVE

In these days of interrupted global supply chain it feels damn good to put something new out there...even if it's just a new material on an existing product.

Especially when the people (YOU) have been asking for it.

The Titanium Preon P1 MKIII is officially taking pre-orders, with shipping expected June 2020.

We're using BackerKit, which means your credit card won't be charged until we ship.

Be sure to click the Pre-Order Store button on the product page to place yours for 20% OFF the future retail price.

Pre-Order Store closes Thursday, May 7.

The World Is Spinning...And So Can You

Copper & Brass Lambda Spin Tops

When the top stops spinning, we'll all wake up from this bad COVID dream, right?

Maybe not quite, but with a Lambda Spin Top you can stave off the shelter in place boredom by setting and beating your best spin time.

When You Need Both Hands

You know that phrase "two is one and one is none"?

Kinda applies to hands, you know?

My work in the shop regularly requires two hands AND illumination. Holding a flashlight isn't an option.

There are a million similar scenarios in life.

"Yeah Jason, that's why they make headlamps."

True, but headlamps lack the versatility I needed.

So I made these patch hats, with are compatible with the 360 Headlamp.

Simple solution, really. Wear a rad hat, attach the 360 Headlamp w/ Foursevens Mini to the velcro patch when you need hands-free light.

If you don't need light, throw a cool patch on there.

I decided on FlexFit hats because they are my personal fave and they also fit a range of noggin sizes. It's also a a mid-volume hat with a "structured" front panel. Perfect for this application.

Got a bunch of bundle options for the Patch Hat and the 360 Headlamp Kit that you can check out at the link below.

One Less Trip To The Store

It's been very encouraging to see many of you stocking up on rechargeable batteries. They're an absolute no-brainer, and like the title in bold says, they WILL cut down on your store trips...which lowers your exposure to you-know-what.

We have AA and AAA rechargeable batteries on the site and ready to go, plus the Wall Charger & Battery Bundle pictured above, which is marked down 30% to $15.

Not going to find a better deal than that. Go ahead and try. I'll wait.

Other benefits of using rechargeable batteries:

  • Reduce landfill waste
  • Save money (potentially thousands – seriously)
  • Protect your electronics
  • Longer run time

19% OFF Continues...

A huge thank you to everyone who has continued to support us during the COVID-related closures and shutdowns. We're running skeleton crew in the shop (just me atm) but I'm doing everything I can to put orders together and in the mail as fast as usual.

Every last order is a huge moral boost for our company, AND for the countless other small businesses and makers out there navigating these uncharted waters and wondering "how will we make it through this?"

Together we'll get through this and fully re-open on the other side.

In the meantime we're keeping this 19% OFF thing going a little longer:

Use code COVID19 to save 19% on:

Again, thank you for your support! Even a like, comment, share of a post on social goes a LONG way...and it's free. Keep spreading the love and hope.

MEET THE BETA MAGNETIC

A Beta QRv2 with Automatic Magnetic Activation.

It's not magic. It's science.

2020 needed some good news. After four years on the drawing board and a year in development, I am thrilled to introduce you to the latest in the Beta line-up.

I think you're going to love it.

In addition to the magnetic activation, this thing pushes the absolute limits on CRI in an LED flashlight. I've included the Yuji 95+ Ultra High CRI LED, which delivers a whole new level of color rendering.

So much more to say about this, but I'll let you head over to the product page and see more for yourself.

Want it now?

The Pre-Order is LIVE, but only for a week. Reserve yours for 25% OFF the future retail price.

PLUS I've thrown in some sweet add-ons with deep discounts that you'll want to check out.
