Update Review: Warranty fast once started - Light worked for 2 charges, then it stopped charging.
Updated Review: This is an update to my initial review where the light failed to charge. My initial review of the light was a disappointment because it failed to charge and slower than expected customer service. However, once their customer service reached out to me, they were much quicker to respond. So be patient with initial contact. They started with diagnostics and validation of failure. Once validation is completed, they sent out warranty replacement very quickly. Now that I have gone through the warranty process, I have to give OLight customer service due for their quick responses once we made contact. I know failures happen and it is a disappointment when it happens to you; but OLight stood by their product and made the warranty process as pleasant as possible. So far the light is working as expected and good as my initial review. It is a quality light that bright and lightweight with very nice accessories. Initial review: Initial Title: Light worked for 2 charges, then it stopped charging. No reply from customer service Review: When it worked for the first 2 charges, it was good. However, it stopped charging afterward. The photo shows it been charged for over 2 hours. Light is about to die. The on button will flash like a slow heart beat when charging but never charges. I have reached out to OLight customer service, but I have not heard back yet. I do not recommend this light.

    It's a nice little light, on the lower settings it lasts for a few rides, but on max it dies faster than I'd like
    it's solid and charges quickly and was easy to install, had it out in very heavy rainfall and it was absolutely fine afterwards with 0 issues which is great. for what it is though it should be a bit cheaper.

    I’m a little over two months in of daily, commuter use of the Olight RN 400 in the often rainy, Pacific Northwest. It has, for the most part, performed as advertised. The packaging, presentation, and build quality exceeded my expectations, and, for better or for worse as far as the light is concerned, I’ve recently found Olight’s service to be second to none. I highly recommend this light for anyone that needs a city use bike light.

    As soon I got the package in hand, I was immediately impressed by Olight’s effort to present the light as a premium product. A tight fitting, heavy duty box with magnetic closures; well thought out graphics; heavy duty foam; instructions; and even a thank-you note. I’d like to say it’s almost too much given that it’s just a bike light but there was definitely a sense of care to let customers know they just bought something worthwhile.

    The light body is a heavy aluminum, the lens is tightly attached, and overall, the light has a substantial feel to it unlike many alternatives that feel like they’ll break from just jarring them around. The RN 400 feels like it could handle an entire commute of heavy pot holes or off-road terrain with ease. I’d say the only concern I have is the rubber/silicone flap that seals out the USB-C charging port. It no doubt seals the port up tight but I worry that it will eventually tear as the ‘pull-tab’ is a bit thin. So far it’s not an issue as it doesn’t require heavy pull to remove the flap.

    Installation of the provided mount is easy and solid and the light locks in tight and secure. Though, this security comes with a slight price as adjusting the light while riding is not possible. It’s pretty much a set it and forget it light mount. I suppose I could loosen the mount a bit but I’d sacrifice that rock-solid security. Attaching and removing the light from the mount is as easy as it comes.

    Won’t go over the specs here, there’s plenty provided by Olight and other reviews. What I can say is that the light is a bright 400 lumens and has a great flood to throw ratio for city commuting, even in areas that lack street lamps. Probably not bright enough for deep trail riding but you could likely get by if need be and if riding slow. Having two flash options is a great idea and I’ve found “Flash 2” to work out really well in daylight traffic commuting. Personally, I haven’t found a use for the other brightness levels as they seem too dim for any practical use. Perhaps if I were commuting on busier streets where there were more ambient light, the lower settings might prolong battery life. Though, I’d probably just stick to the brighter flash options in that scenario.

    As for battery life, I’ve found that running the light at the “High” 400 lumens will definitely run the battery down as fast as advertised. I’m pretty much recharging each day as my total commute is about 1.25 hours. I can definitely eek out more time and likely push it to recharging every 1.5 days but it seems easier to just throw it on the charger at the end of the day rather than risk riding with no light on my dark, early morning commute.

    This leads me to my experience with Olight Customer Service. About a month and a half in of great use and pleasant experience, the light quit charging. Not sure what happened, it just stopped. I finally got around to writing Olight about the issue- just before the Christmas holidays, and, without question, they promptly responded saying they’d send out a new light. A couple days later, two days after Christmas no less, a new RN 400 arrived at my doorstep. Wow. That is customer service at it’s best. I didn’t even expect to hear from them until the new year.

    I highly recommend this light and when funds permit, I will gladly purchase the RN 1200 for a main light (to be run at medium 600 lm output for longer battery life) and run the 400 as a secondary flasher.

    Really impressed with how much light this tiny thing puts out. Decent battery life for it's size. Very solid metal body and easy to install and remove when not in use. Olight never disappoints.

    It’s well built with good quality materials. It works perfectly as night light and daytime light. I wish the light on the button was brighter, I can’t see it when using it on daytime so it’s hard to check if my light is on or if my light is in the light mode.

    La lumière a très bien marché pendant 3-4 mois, et je trouvais cette lumière excellente au niveau de l’intensité lumineuse et l’attache garmin…
    …MAIS depuis elle ne fonctionne plus du tout. La batterie ne se recharge plus…. la lumière n’est plus fonctionnelle après seulement quelques utilisations ponctuelles

    J’ai acheté deux de ces lumières il y a environ trois ans pour les mettre sur une trottinette électrique. La qualité est irréprochable. Je les utilise très souvent et je n’ai jamais eu de problème avec elles. Le système de fixation est très bien fait et solide. Elles sont très jolies et agréables à tenir en main. Le corps en aluminium en fait une lumière solide en cas de chute. Personne ne peut se plaindre de la durée de la batterie étant donné que vous avez acheté la RN 400 au lieu de la RN 800 ou même la RN1500. Si vous voulez plus de batterie, achetez le plus gros modèle, c'est aussi simple que ça. J'ai choisi la RN 400 pour son côté compact, alors je ne m'attends pas à avoir 8 heures en mode élevé. L'autonomie de la RN 400 en mode élevé est d'environ 1 h 30, c'est pourquoi j'en ai acheté 2. J'en garde une en réserve dans mon sac à dos. Autre chose, c'est qu'en 3 ans, les performances n'ont pas diminué, preuve que c'est un bon produit.
