Why use Voucher Magpie?
Every Lumen code here comes from Lumen itself or its official affiliate programme, never copied from another voucher site. When you shop through our links, Lumen may pay us a commission. It never changes your price. We give 50% of that commission to the charity, club or school you choose, at no extra cost to you.
About Lumen
Lumen makes a handheld device that you breathe into, paired with a phone app. The device measures the carbon dioxide in your breath, and the app uses the reading to estimate whether your body is mainly using fat or carbohydrates for fuel at that moment, then suggests a nutrition plan for the day. It's made by Meta Flow Ltd, a company organised under Israeli law, and was started by twin sisters Merav and Michal Mor, both PhDs in physiology, before launching through Indiegogo.
The device needs a paid membership to use the app. On the UK shop during our visit, the device was £349 (shown as reduced from £448) with the first 12 months of membership free as a limited-time offer; the membership then renews automatically each year unless cancelled. The app links with sleep and activity trackers, logs food and gives daily targets.
Orders usually ship within 4 to 7 business days and arrive 7 to 10 business days after that. International orders can attract customs duties and taxes, which the buyer pays. You can return the device within 30 days of delivery for a refund, though return postage is at your cost, and it carries a one-year limited warranty. The app's suggestions aren't a substitute for medical advice, so speak to a GP about any health concerns.
Lumen delivery and returns
| Delivery | Orders usually ship within 4 to 7 business days; global standard shipping generally takes 7 to 10 business days. Customs duties, taxes and import fees on international orders are paid by the recipient. |
|---|---|
| Returns | Email [email protected] within 30 days of receiving the device to return it for a refund. It must be complete and in its original packaging, and you pay return shipping. One-year limited warranty against defects. |

Ways to save at Lumen
- Check what membership is included before you buy: during our visit the device came with the first 12 months free, after which it renews automatically each year.
- Set a reminder before your membership renews if you don't want to keep paying, as subscriptions renew automatically unless cancelled.
- Sign up to the newsletter on lumen.me, which offers a thank-you code (20ME) off your order.
- Keep the box, charging dock and cable in case you use the 30-day return window, and budget for return postage.

How do I contact Lumen customer service?
Use the help centre on the Lumen website.
Can I use more than one Lumen discount code?
Usually not: most stores, including Lumen, accept one discount code per order. Automatic deals and sale prices can often be combined with a code, so check the terms on each offer.
Does Lumen offer a first-order discount?
We don't have a first-order code for Lumen right now. Sign up for alerts and we'll email you if one lands.
Can I use a Lumen discount code on sale items?
It depends on the code. Many discount codes exclude items that are already reduced, so open Terms on the code before you use it.
Why didn't my Lumen code work?
Most codes exclude gift cards and items already reduced, and some need a minimum spend or are for new customers only. Open Terms on the code, or tap "Didn't work?" and we'll recheck it.
Are these Lumen codes verified?
Every Lumen code here comes from Lumen itself: its own daily feed through its official affiliate programme, or its own website. Each offer shows when we last checked it.
Does Voucher Magpie donate to charity?
Yes. When you buy from Lumen through our links, Lumen pays us a commission, and we give 50% of it to the charity or club you choose. We pay each cause its confirmed commission every quarter (Jan, Apr, Jul, Oct), once the shop has confirmed the sale, usually 30 to 90 days after the order.
Does using Voucher Magpie cost more?
No. You pay Lumen's normal price, less any discount. Our commission is paid by Lumen or its affiliate network, not by you.
How do I use a Lumen discount code?
Tap Get code and we copy it for you. Add your items to the basket on the Lumen website, then paste the code into the discount or promo code box at checkout.
