OVERALL IMPRESSIONS/COMMENTS:
The Magicshine SEEMEE 150 MAG bike light comes with mounting hardware that allows installation on a seat post, under the seat, or on the handlebar. The light includes a quick-release housing, a short USB-C charging cable, a seat post strap, and a clip with cable ties for mounting under the seat. The instructions indicate it can be mounted on a helmet, but only for a LUMOS-branded helmet. The magnet built into the back of the light is very strong—it pulled the quick-release adapter out of my hand when placing it on.
Although this light is marketed as a rear bike light, I was surprised to discover that double-clicking the power button switches the output mode from red to white light. There are four flash settings and high/low “always on” settings. All settings are the same whether the light is red or white. Although I only intended to use this as a rear light with a daytime flash setting, I ended up comparing it against my other 800-lumen and 1600-lumen bike lights.
TESTING:
I replaced my Bontrager Flare R City rear bike light with the SEEMEE 150 MAG rear bike light using the seat post mount. As I tend to bike primarily on trails and rural roads, I primarily use only the brightest flash setting for my rear light. Even in the bright afternoon sun, my riding partner noted this new light was exceptionally brighter compared to my old Bontrager light. My friend’s rear light is equally bright at its highest setting, but it is much larger with two LED bulbs and a concave reflective lens for each. He was so impressed with the compact size of the SEEMEE 150 Mag light and its brightness that he would consider it as a future replacement. After a couple of rides on mixed trails, including gravel, dirt, and wooden bridges, the SEEMEE MAG 150 remained firmly seated in its magnetic housing.
For disclosure, I tested the SEEMEE MAG 150 rear light concurrently with the Magicshine HORI 900 light. While evaluating the Magicshine app for the HORI 900, I was able to add the SEEMEE MAG 150 rear light as another device. There aren’t any additional settings that can be managed through the app via Bluetooth, but it did display the remaining battery life and temperature for the SEEME MAG 150. Although the instructions indicate the battery will last for 7.5 hours using the turbo flash setting, I always charge it the night before my weekend rides as a precaution – better to always be seen.
As the SEEMEE MAG 150 is intended to be used primarily as a rear bike light, I only compared the white light output using the turbo flash mode in a side-by-side test with my old 800 and 1,600-lumen front bike lights. At 150 lumens, the SEEMEE MAG 150 isn’t close to matching those other lights or the HORI 900, which isn’t surprising given the light is emitted from a ring of tiny LEDs. That said, if you were caught out riding at night in the dark and the SEEMEE MAG 150 light was the only functioning light on your bike, you could remount it on the handlebar with the seatpost mount.
PROS:
• Lightweight and compact
• USB-C rechargeable
• Battery lasts up to 23.5 hours in Eco Flash mode and 7.5 hours in Turbo mode (red light setting)
• Mounting hardware included for seatpost, handlebar, or under-seat placement
• Can switch from red to white light as a front light
CONS:
• No hardware provided for helmet mounting
SUMMARY/FINAL THOUGHTS:
At the time of this review, the Magicshine SEEMEE MAG 150 bike light is $29.99. It has plenty of flashing and “always on” lighting modes, and includes hardware for various mounting options. The magnetic base and clip are very strong, keeping it securely in place even when riding on rough terrain like gravel and dirt trails. I like it so much that my Bontrager Flare R city rear light now serves as an emergency backup.
Since the SEEMEE MAG light can output white light as well, it’s sufficient as a front light for riding when it gets dark. However, at 150 lumens, I plan to stick to using turbo mode for maximum visibility as a rear red light. Although you can download the Magicshine app, battery life is the only useful information it offers, so I would skip it.
If you are like me and store gear or emergency supplies in a seat bag, consider the SEEMEE MAG 150 bike light. It’s bright, compact, and at $29.99, a good value compared to rear lights that cost more or offer less useful features (like auto on/off).
