OLIGHT Seemee 30 C Bike Light 30 Lumens Tail Light 230 Degree Visibility, 800m Viewable Range, USB Rechargeable Bike Break Light, IPX6 Waterproof, Road and Urban Cyclists

This thing is way smaller than I expected. The photos make it look a lot bigger, but in person it’s tiny. That said, it’s built like a tank. The body feels solid, and the rubber strap is thick and tough. Honestly, it feels overbuilt in a good way. The brightness is great, especially for how small it is. Super easy to clip to my seatpost. The only thing I didn’t love is the little rubber bumper on the back that covers the charging port. It’s not attached, so it pops off every time you go to charge it. I ended up gluing one side of it down so I wouldn’t lose it. Other than that, it’s a great little light. Super handy and clearly made to last. Definitely would recommend and buy again.

Great little tail light. Great visibility even in daylight with brighter modes. Virtually weightless and doesn't need much space on your seatpost. Also has a great variety of illumination modes. Good value for the price

Love this light. Great color, brightness, and longevity.

I got this based on the name and the fact that they make weapons lights so I figured this should be pretty good. It has a few different modes and appears quite bright to me. I would recommend this absolutely.

Kinda hokey mounting system - basically a rubber band to fit around your seat post. Lightweight, yes. Secure, probably. Long lasting - perhaps not. Output probably as stated - 30 Lumens, so more of a marker light vs warning light. Claimed 230 degree visibility is believable, but light level definitely falls off the further from centerline you get. If weight is main criteria, not a bad choice.

Pros: - Looks stylish and tidy - Bright enough for most people during day or night (I would think) - USB-C is pretty standard but good to see nonetheless here - Pretty low price for a decent rear light Cons: - Disappointing battery life even on strobe modes (I guess I am used to the Cygolite Hotshot’s loooong battery life) - I noticed that it needs to be charged after a month or so after a full charge even when it’s been sitting on the bike not being used. - The strobe mode need a faster strobing option, but the included strobe modes will do the job - The rubber band clasp was quite a tight fit on my Trek Marlin 5’s seat post. (Essentially my fault for not thinking about that!) Review: I have the Trek Marlin 5, 2023 model in red, and this thing looks perfect on it, although, it was quite a tight fit, but it stayed on there and didn’t snap off from the absurdly tight fit until I needed to recharge it. I almost wanted to return it due to this tightness, but I said to heck with it and kept it because it looks good, the strobe modes are decent enough, and it’s (at least it should be) bright enough. I am upgrading (if you will) from a Cygolite Hotshot 100 Lumens model, and while I enjoy the simpler design of the Olight…this Olight is no comparison of course in terms of brightness or modes available. Having used this for a month, it’s a good enough rear bike light to be seen day or night. Overall, I wish it had longer battery life, a faster strobe mode, and a longer band to fit around my bike’s seat post. I had only been on a handful of rides with my new Trek bike, and I’m pretty sure this is my 2nd time charging up this Olight. On a ride tonight before this review, I was thunderstruck when I came back and realized it was off! Well maybe not that surprised…it’s cheaper and smaller than the Cygolite Hotshot. I may have to recharge this every time when I know for certain I will go biking to prevent a “dead rear light” scenario happening again. Bleh. I guess I am used to the Cygolite Hotshot 100 Lumens longer battery life that I only had to charge every few months if even that with not too many rides/long rides. If I had the chance to buy a different rear bike light knowing what this would be, I probably would due to the aforementioned annoyances, but I didn’t feel like a return was needed. There are some other rear bike lights out there, such as I think Cygolite makes their own model that has a similar design. I decided to try Olight because it was cheaper, it had good reviews, and 30 Lumens seemed like enough and not overkill at times with 100+ frickin’ lumens. Nothing at all against Cygolite, I just just wanted to try something else for my new bike. I think Cygolite’s similar designed model was $25-$30 and has a higher lumen count. UPDATE: December 2024 - this tail light loses its power after maybe a month. So, you can expect to charge it back up if you forget to use your bike, or if it’s your backup tail light and it hasn’t been charged in a while. I know li-ion stuff can do this, but it’s just disappointing when I want to go for a ride and haven’t gone out in a month and the thing is dead. It’s one more thing you need to know to get ready before riding even if it was fully charged a while ago and hasn’t been in use.

Who's ever heard of Olight? Not me! It sounds as weird as Anker... clearly, that brand is going nowhere with that name... Manufacturers are innovating, releasing their own brands, and Western companies that we've relied on for quality rest on their laurels, fall behind, and are failing to innovate... Anyway, this thing is pretty cool. Fast USB-C charging. Simple but solid construction = less likely to fail / break and also lighter. Rubber back stays put on seat stays or the seat post, and come off to reveal the USB-C port when you want to charge. I haven't pushed this to its limits but I can ride about a week (6-10 hours) before I decide to charge it. 5 settings with nice solid LED lights that aren't painful to look at or blinding for cyclists behind you but visible enough for cars to see in daylight: - Solid low - Solid high - Bright blinking every second (what I use most often) - Less bright blinking every second for three seconds, then pausing for one - Solid low with blinking high every 2 seconds

Terrible product. Charges for only two hours and stops. Last for about an hour, if that. Do not buy!!
