A Powerful Companion For Long Night Rides You don't have to be a Pro to use the LEYZNE 1800i MEGA DRIVE LED FRONT LIGHT but with 1800 Lumens 'under-the-hood' you'll most certainly look (and feel) like one. This is an "i" model that can be used by connecting it to a separately-sold battery pack like the 6,000mAh LEYZNE INFINITE LIGHT POWER PACK, which is very useful for long night rides as it effectively doubles your fun time.Great For Off-Road Rides Even In Wet Conditions Ideal for all seasons the LEYZNE 1800i MEGA DRIVE LED FRONT LIGHT will easily light your way through the darkest lighting conditions regardless of whether you're riding off-road on your mountain bike, racing on your speed machine or using it as a hand-held torch along the path to your garage before attaching it to your bike for a pre-dawn ride. Furthermore, its output is optimised by Lezyne's Tri-Focus Optics, which creates a brighter centre spot in a large wide-angle pattern.Built-In Cooling Fins Prevent Overheating Constructed from CNC machined Aluminium the LEYZNE 1800i MEGA DRIVE has built-in cooling fins that improve its overall performance by reducing overheating. It is even compatible with optional features (sold separately) such as Lezyne's Remote Switch and Smart Wireless System which allows lighting modes to be customised through a smartphone app. Now, that's super versatile! 7 Lighting Modes The MEGA DRIVE 1800i offers 7 combined lumen and flash modes and can be easily charged using the included USB cable. The 7 hour recharge session will give you 1hr 40mins worth of full force 'Overdrive' lighting or up to 148 hours of Femto flashing light (15 lumens). The light also includes an Auto Day/Night sensor and a power button with a battery indicator, so you can always see the battery level.Pack contents 1 x Lezyne 1800i Mega Drive Pro Front Light 1 x Silicone Rubber Mounting Strap for bars to 35mm 1 x Micro USB charging cable 1 x User ManualFeatures • Lezyne Mega Drive 1800i LED Front Light • Ultra-high output LED cycling light • Built-in auto day/night sensor • CNC machined Aluminium body • Fits 35mm bars • Waterproof to IPX7 • Mode Memory function • USB rechargeable (cable included) • Seven (7) combined lumen and flash modes • Silicone rubber mounting strap • Rubber plug protects USB recharging port • Heat-dissipating CNC machined aluminium construction • Tri-Focus Optics for a brighter centre spot in a large wide-angle patternCompatible With • LED Remote Switch • Smart Wireless System • Leyzne Infinite Light Power Pack (6,000mAh) • Handlebar Mount (Aluminium) • Handlebar Mount (Composite Matrix) • Helmet Mount (Aluminium) • Helmet Mount (Composite Matrix)Practical Benefits • 1800 lumens output on OVERDRIVE setting • Can be powered by a separately-sold battery • Compact, multi-purpose and durable • Widely illuminates the front with wide visibility • Built in cooling fins reduce overheating • One-touch desorption is possible • Power button with battery indicator • Lighting Modes can be customised through phone app • Connects to other Lezyne Wireless compatible lights and Y12+ Lezyne GPS • Compatible with a wide range of handlebar diameters by attaching an adapterPower Settings & Battery Life • Blast: 1000 Lumens / 2hrs 30mins • Enduro: 600 Lumens / 3hrs 45mins • Economy: 250 Lumens / 10hrs • Femto (low energy): 15 Lumens / 148hrs • Flash: 150 Lumens / 33hrs • Pulse: 150 Lumens / 38hrs • Overdrive: 1800 Lumens / 1hr 40minsSpecifications • Mounting Hardware: Silicone Strap (for bars to 35mm) • Number of bulbs: 3 x LED • Weight: 236g • Lumens: 1800lm • Light Modes: 7 • Power Source: USB Rechargeable • Recharge Time: 7hrs • Max.
