"Excellent company to deal with and their products are fantastic. RN 1500 bike light is brilliant (excuse the pun) and to receive a 1R2 keyring torch as a free gift was a bonus. Keep up the good work!"




RN 1500 is specially designed for serious cycling demands and challenging riding conditions. It is a multi-functional bicycle light powered by a 5000mAh 21700 battery with a maximum output of 1500 lumens. All-in-one design bike headlight suitable for road, urban, and mountain trails. Anti-glare light distribution with a safe cut-off line, to reduce visual distractions for motorists, cyclists or pedestrians. It introduced USB-C charging & discharging integration port that supports heavy current. Hence, to bring a faster charging & discharging experience. RN 1500 can be tightly installed on our front mount, or under the GoPro camera mount. It is a powerful, reliable companion in the dark.

The Olight RN 1500 is part of the somewhat confusingly named RN series of front road cycling or commuter lights. With this series of lights, Olight has utilized its simple rounded aluminum housing, Garmin compatible mount, and soft beam cut-off lenses. Larger lights like the RN 3000 use a dual-LED design while the RN 1500 and the RN 1200 use a single LED lens. The confusing part is that Olight also offers more compact lights like the Allty, which are downsized versions of the RN 1500. Visually the RN 1500 is actually identical to the RN 1200 but thanks to the larger 5000 mAh Li-ion battery, it’s able to achieve a higher lumen output. There is only one charging port at the rear, and the silicone protective cover can provide IPX7 protection level, and there will be no problem in riding the lights in heavy rain. The red light is on when charging, and the green light is always on when fully charged. It takes about 2 hours to fully charge. The headlight is a Garmin base, and it is also equipped with a Gopro interface conversion seat. Different sockets allow the RN1500 to cope with more usage scenarios, such as the mature GoPro bracket that can be installed on helmets, wrists, backpacks, wheels, and other places you can't think of.

       RN 1500 OUTPUT    

Consistent with the other RN lights, the RN 1500 has a simple one-button interface and a two-level menu. Holding the button turns the light on and off, while a single press cycle through the mode options. There are three constant modes: low (300 lumen / 12:30 hr:min), medium (750  lumen / 4:00 hr:min) and high (1500 lumen / 1:40 hr:min). The jumps between the constant modes are large which makes them easy to differentiate. We found the medium mode worked well for urban riding while the high was ideal for dark roads or trails.  There are an additional two flash modes: high-frequency on/off flash (0-750 lumen / 11:30 hr:min) and an interesting pulsing flash (0-750 lumen / 10:00 hr:min). The second flash mode is well suited for daytime riding as the irregular flash attracts attention and has a distinct pattern. We would describe the beam pattern on the RN 1500 as more of a sport style with a brighter center that drops off the sides. It’s well suited for road cycling or even mountain biking as a helmet-mounted light as it’s a bright and even beams. The anti-glare lens design doesn’t produce a sharp beam cut-off instead it helps redirect more light onto the ground in front of the bike. It’s a simple design that is particularly useful for road cyclists or commuters. Small cutouts on the front lens also help improve the side visibility of the light which improves the nighttime visibility at intersections.

       21700 Power &USB-C Charging    

The RN1500 is powered by the current mainstream 21700 battery, with a capacity of 5000 mAh and a maximum brightness of 1500 lumens. The battery can only be charged and cannot be replaced directly. The flashlight uses USB-C charging, and the charging port has a waterproof plug design. At the same time, it also supports 5v2a discharge, which can be used as a power bank to charge mobile phones, headphones, cameras, and other devices.

       HOW TO USE RN1500?    

The RN1500 bracket uses the Garmin interface. When in use, the flashlight can be locked by rotating it 90 degrees. After locking, it is still very strong. The way the bracket and handlebar are fixed is also very careful, using the design of straps instead of ordinary circular clamps, and comes with straps of various sizes. This design can also be installed on different shapes of special-shaped handlebars and windbreakers, and the compatibility is extremely strong. The fixing method is also very simple. Just pass the strap through and directly lock it with the inner hexagon. Because there are rubber strips on the inside of the strap, there will be no problem with rotation and shaking after tightening. It is also because it cannot be rotated after being fastened, so it is recommended to adjust the light height during installation because it is difficult to adjust after the installation is firm. After installing and adjusting the bracket, no matter how bumpy it is on the road, there will be no sign of shaking.

In addition to being used as a car light, the RN1500 can also be used as a flashlight and power bank for daily commuting. The 5v2a discharge speed and the 5000mAh battery can satisfy me for a day of charging and lighting use. If I can have an 18w fast charge even better. The maximum brightness of 1500 is not inferior to the tactical flashlight, but it is only missing tactical functions such as one-button lighting. The LED power indicator function is integrated into the switch. When the green light is on, when the power is 100%-21%, the red light is displayed when the power is 20%-11%. When the red light is flashing, it is below 10% and needs to be charged immediately. As a bicycle light, the RN1500's performance is definitely excellent, with high brightness, long battery life, waterproof and anti-drop, and a sturdy bracket design that makes it possible to illuminate the way home at any time, and is a strong backing on the road.
