As you may be aware, Guyot Designs makes hard core products while still talking the enviro-talk. Last week we discussed their Stainless Steel Water Bottle. This week we’re all about the accessories.

The Firefly is their cool contraption that turns your bottle into a lantern. How does it work? Well, the lid contains an integrated LED light which spreads light throughout the bottle. It has variable light levels so you can have a nightlight for stormy nights, or a reading light for enjoying your latest read; the control is at your finger tip! The electronics are in a separate sealed compartment, so there’s no risk of water leakage.

And as it’s compatible with all standard wide mouth bottles and Guyot’s own Clean Air Original SplashGuard, you’re good to go.
