Yes. Gloworm’s stock for Europe and United Kingdom is based in Athens, Greece. We ship internationally.

Your order will be shipped within one business day. We use DHL express and it takes 2-3 days to arrive. So in total, our products have an average delivery time of 3-4 business days.

For shipments in EU countries no customs and import charges are applied.

Product Support

The LEDs we use boast an almost unlimited life expectancy. Therefore, it rather makes sense to look at how the luminance decreases over time. Our long-term tests indicate that the LEDs lose merely about 10% of their luminance after 2 years of PERMANENT operation (17,500 hours).
To make it short: Life expectancy is no longer an issue!

Gloworm utilises CREE LEDs.
Cree is the market-leading innovator of lighting-class LEDs.
Currently we only use the XML2 LEDs and XPG2 LEDS in the CX Urban lights.

The Gloworm X series lights are designed to an IP67 rating. This means they can be submersed but it is not recommended. The CX series is designed to an IP65 rating which means they are dust tight and can be used in rainy conditions.

The life of a battery pack depends on different factors. On the cell type, on how much it is used and on how it is treated. In general, a life of 300-400 charging/discharging cycles can be assumed before the battery’s capacity decreases significantly (80% of the nominal value). This corresponds to a minimum period of use of approximately 2-3 years if the battery is used twice a week. With careful storage when the battery is not in use, a life of 2-3 years is realistic.

In many cases, the battery and the charger are in perfect condition, merely the battery protection has been triggered. To solve this, simply leave the battery connected to the plugged in charger and after a while (NB: it may take up to two hours) the battery will charge again.

Charge the battery ideally to 50-75% and keep the battery in a cool dry place for no longer than 3 months. Temperatures below 15°C are favourable. The fridge in an airtight container is a good option.
Extreme example:
Storage of a fully charged lithium-ion battery at 30°C (direct sunlight) irreversibly damages the battery
it may even fail completely.

If you expect your next use to be no longer than the remaining capacity will last, do not charge the battery immediately. The life of a lithium-ion battery is also determined by the number of charging cycles. Each charging cycle, even the shortest, is recognized by the battery as such; therefore, rather avoid charging the battery unless it is really necessary.

Yes, without limitations. All our lights are absolutely heat-proof. Caution! Please be aware the enclosure will heat up during use, however this is completely normal so please take care when handling in order to prevent injury.

Absolutely! Whatever your passion is, be it riding, running, caving or adventure sport racing, Gloworm will be there to light up all your adventures!

If you are not 100% happy with your purchase, return it within 14 days for a full refund. Plus we΄ll even refund the return shipping. However, we΄re pretty sure once you get hold of one of our lights you΄ll never want to let it go!

We are currently looking for distributors. If you are interested, please CONTACT US to discuss.

G2.0 Support

We no longer include a rubber cap anymore. They were only aesthetic, so nothing to worry about.

They are USB PD chargers.
Have a look at the product’s page for a full list of specs and charging times

The battery can be charged at up to 30W from a USB PD charger.  From other chargers it can charge but as every charger is different there are not accurate specifications for this. We can say that QC will charge at 17W (12V) and Apple Chargers also charge at their dedicated charge speed. 

Yes, so that’s good news for our friends in the North that use GW lightsets with their snowmobiles.

Our fuel gauge, that measures capacity, learns with every charge.  So, it becomes more accurate over time.  To avoid the initial learning process, we ‘taught’ the battery through programming what it should show.  However, if a battery starts its life at low charge, this does not work.  Therefore, you get an issue like you are seeing.  There is nothing wrong with his battery.  The battery is just learning, and it will come right after 3-4 charge cycles. In the meantime, the most important factor is the runtime and how long his light lasts.

This is a known issue, and it will change in the next update. The issue occurs when the time is over 24 hrs.lays a completely wrong time left or it shows unreadable characters
