Precision Illumination for the Night Ride
The LUNAR Callisto sits low and compact on your handlebar or helmet, a discreet block of black anodized aluminum that blends into the geometry of your bike. Its presence is felt more than seen until you need it, then it delivers a focused beam that cuts through the dark without glare.
This 2-in-1 unit handles both front illumination and rear visibility, making it suitable for commuters, racers and anyone who rides after dusk. The included mounts ensure it stays secure whether attached to a bar or a cap.

MATERIALS
Machined Aluminum Construction
Housed in anodized aluminum, the Callisto offers a rigid, cool-to-the-touch surface that resists corrosion and wear. The material choice keeps the weight down to 90 grams while providing a durable shell for daily use. Its matte black finish absorbs light, reducing reflections when the lamp is off.
PERFORMANCE
High Output CREE LED Technology
Powered by a CREE XP-G3 LED, the front unit produces 600 lumens of 5500K white light, offering a crisp, neutral tone that renders road details clearly. The rear light provides 10 lumens of steady or flashing red, ensuring visibility from behind without overwhelming night traffic.
PRACTICALITY
Flexible Mounting and Charging
The package includes both a standard helmet mount and a GoPro-compatible adapter, allowing versatile placement. Charging via USB-C takes three hours, filling the 1200mAh Li-ion battery. The IP65 rating protects against dust and water jets, handling rain and spray with confidence.
DETAILS
