The E3 PRO 2 stands out as a top - tier model in our dynamo light series. It's a multiple - award winner and ranks first in most magazine reviews, clearly showing its superiority. Whether you're commuting to work or exploring remote landscapes, this light provides outstanding illumination even at low speeds, like when climbing a hill. The glowing Supernova logo is a real highlight. It not only makes the light look great but also boosts your safety with highly visible side - illumination. The mechanical on/off switch on the back makes it perfect for use with USB charge modules. With a glare - free lens, the E3 PRO 2 creates a wide, even carpet of light on the ground, even at low speeds. Most of the light is directed towards the ground, making it seem very bright, and the beam is long enough for fast riding. Product details include a brightness of 205 lm, an input voltage of 6V AC dynamo, a 5 - minute stand light, a Terraflux 2 lens, a Power LED illuminant, dimensions of 69 x 40 x 40 mm, a 6061 Aluminum material, a weight of 110 g without the bracket, and a 5 - year warranty. In a joint evaluation with VSF experts, 230 retailers assessed 11 dynamo lights on the market. The E3 PRO 2 was one of the few to receive the prestigious VSF all - ride seal of quality. The VSF awards this seal to products that excel in functionality, usability, lifespan, material quality, and warranties, also considering production's social and environmental conditions. The TERRAFLUX 4 lens, now in its 4th generation, is a milestone in Supernova's development. It produces a bright and uniform illumination, with 90% of the light directed where it's most needed: on the road. It forms a broad, even carpet of light that stretches from the front wheel far into the horizon. The built - in daytime running light ensures good visibility during the day, and at night, it helps illuminate traffic signs and low - hanging branches. Our aerospace aluminum housings are super strong and have excellent heat conduction properties. They're anodized, salt - water resistant, and can withstand harsh conditions. Extreme tests by ultracycling athletes prove their reliability and durability. We focus on high performance and efficiency. Cooling significantly extends the service life. Ideal heat dissipation requires careful material selection and smart construction, like a seamless single - piece aluminum housing. Integrated heat sensors keep the headlight at an optimal temperature in extreme situations. Our over 20 years of experience with LED front lights shows in these design choices.

Using the Supernova E3 Pro 2 Dynamo Front Light is easy. Just use the mechanical on/off switch on the back to turn it on or off. It can be used with USB charge modules for added convenience. When riding, you'll notice excellent illumination even at low speeds, which is great for climbing hills. For maintenance, keep the light clean. Wipe it with a soft, dry cloth regularly to remove dirt and grime. Since it has an aluminum housing that's salt - water resistant, it can handle different weather conditions, but try to avoid long - term exposure to extreme wetness. If you're not using the light for a long time, store it in a dry place. The built - in heat sensors will help keep the light at a good temperature, but avoid leaving it in direct sunlight for extended periods. Also, remember that it has a 5 - year warranty, so if you encounter any problems, you can reach out for support.
