FAQ: Prometheus Beta-QR

Can I use Li-Ion rechargeable batteries?

NO! These lights are not compatible with Li-Ion batteries. They will damage the light because the voltage of a Li-Ion is more than twice the nominal 1.5V of an alkaline or NiMh battery.

If you want to use rechargeable batteries they should be NiMh (Sanyo Eneloop). You CAN use a “lithium” disposable battery though. They market these for use in cameras and electronic devices and tend to have higher capacity than an alkaline battery.

Where are these lights being manufactured?

These lights will be manufactured by a reputable flashlight company in China. There is more info within the campaign under the section “The Challenge: Making a lot of Beta-QR Lights.” I’ve been working with this factory for the last 11 months, and I will be there (already booked a flight) at the end of October, days after the completion of the campaign :)

Will you offer the 3 mode driver in the EN/HAIII/KS Green lights...or only for the copper?

For this campaign, the 3 mode is only offered in the copper light. Normally this might be a stretch goal, but timing a holiday delivery will already be tight, so it is not feasible to increase the complexity and scope of the project at this time.

If the campaign does well overall, I am considering offering a “pill” that is user swapable and may feature different driver modes and/or LED types. A “pill” is flashlight lingo for an assembly consisting of LED, driver, and the heat sink that holds the two together.

Do all the different flashlights come with a brass Quick Release?

Yes, that’s correct. All of the QR’s are brass (just like in the photos) and will not be color coded to the lights.

Which finish is the most durable?

Any metal finish will wear over time, especially when carried with other metal objects. The copper will nick and scratch, but since it’s solid copper it will always look like copper. The HAIII is extremely hard and durable, but when it does wear off, it will have a very light grey color underneath. The EN is very durable but very thin. It will nick and scratch, but when it wears off it will be harder to tell because the underlying metal is a similar color.

Will the Copper and Electroless Nickel exhibit patina (tarnish) over time?

Yes, both finishes will patina when in contact with the natural acids and oils from daily use. However, each light will take on a patina that is unique to each user and the life they lead. In either case, the bright finish can be restored by a silver polishing cloth or similar metal polish. Never use abrasive cleaners!

Will you offer the same warranty as on your custom made lights?

You bet. I stand by my products and the Beta-QR will be protected by the same lifetime warranty. This excludes the LED, electronic driver, glass window, and the QR mechanism itself. These are all considered “wear items” and are covered for a period of 1 year. If one of those components fail after 1 year has elapsed, you may return the light and it will be repaired (if possible) or replaced for a reasonable fee.

BackerKit FAQ

What is BackerKit?

BackerKit is a service that crowdfunded project creators use to keep track of hundreds to tens of thousands of backers—from shipping details, pledge levels, preferences and quantities, whether they have paid or had their card declined, special notes, and everything in between!

The BackerKit software and support team is independent from the campaign’s project team—BackerKit does not handle the actual reward shipping. For more information about the preparation or delivery status of your rewards, please check the project's updates page.

How does BackerKit work?

After the campaign ends, the project creator will send you an email with a unique link to your survey. You can check out a walkthrough of the process here.

I never received my invitation. How do I complete the survey?

The most common reasons for not receiving a survey email is that you may be checking an email inbox different from the email address you used to sign up with Kickstarter, Indiegogo or Tilt Pro account, or it may be caught in your spam filter.

Confirm that the email address you are searching matches the email address tied to your Kickstarter, Indiegogo, or Tilt Pro account. If that doesn’t work, then try checking your spam, junk or promotions folders. You can also search for "backerkit” in your inbox.

To resend the survey to yourself, visit the project page and input the email address associated with your Kickstarter, Indiegogo or Tilt Pro account.

How do I update my shipping address?

BackerKit allows you to update your shipping address until the shipping addresses are locked by the project creator. To update your address, go back to your BackerKit survey by inputting your email here.

When will my order be shipped, charged or locked?

That is handled directly by the project creator. BackerKit functions independently of the project itself, so we do not have control of their physical shipping timeline. If you want to check on the project’s status, we recommend reading over the project's updates page.

I completed the survey, but haven't received my rewards yet. When will they arrive?

As BackerKit does not actually handle any rewards or shipping, the best way to stay updated on the shipping timeline would be to check out the project's updates page.
