BRIGHT EYES Helios Fully Waterproof 1600 Lumen Rechargeable Mountain, Road Bike, MX Headlight, 6400mAh External Battery (Now 4+ Hours on Bright Beam) - Included: Free Diffuser Lens and Free Taillight

Bright as heck

I don't write many reviews, and I am not a paid reviewer...I bought this product with my own money at the full price. This light is bright, like a car headlight on the high beam brightness, and it is awesome. It is well manufactured, solid and functions well. The kit that comes with this has everything you need to hook it up to your bike, head or whatever. I used the diffuser on the light, because it makes the beam wider and covers more of an area, and the installation was simple and came with everything you need. I also hooked up the taillight, and it is a nice quality item that came with the required batteries...you can see it in picture number 4. I did have an issue with the charger or the battery, I wasn't sure which it was, so I reached out to the company and was emailed back very quickly from Donald who said he was shipping out replacements. Turns out it was the charger, a simple little broken piece, and now everything is great. This was top quality, personalized customer service on top of an incredible product...what more can you ask for? I know there are $10 lights out there, but once you ride around in a Cadillac, that Ford Pinto doesn't seem like such a deal anymore...this is worth every penny. Picture 1: Light is on bright about 10 feet or so from my garage door...looks exactly like my truck lights (1 beam) in terms of brightness from the same distance. Picture 2: Light on low from about 5 feet away. Picture 3: Light on low with green LEDs lit to show contrast. Picture 4: The included taillight. Picture 5: Just another view. I use this bike to cruise around my neighborhood, and with all of it's lights, I am easily seen. But the headlight absolutely allows me to see whatever I want, it is that bright and I hightly recommend it.

In spite of its size, this is the most powerful bicycle headlight I have ever used. Battery took approximately 5 hours to charge right out of the box. I have used the light for a total of 4 hours now, and it is still going strong, and having the strobe feature is a bonus for daytime riding. I feel more comfortable on the road knowing that oncoming traffic can see me better. If you want a powerful light at a reasonable price, this is it! This light is quick and easy to mount and dismount on the bicycle. The battery pack was also very easy to mount to the bike, and is perfectly sized so as not to get in the way. The standard beam offers enough light for in-city riding where there are plenty of street lamps, but doesn't give quite enough light on either side when riding the trails and back roads. After I installed the diffusing lens, I had no difficulties navigating outside of the city. The lens was super easy to install. I haven't tested the light out in the rain yet, but I am confident that it will perform outstandingly in inclement weather, just as it does in good. But what do I like even more than the light? THE CUSTOMER SERVICE!! I have not had such a pleasurable experience with customer service representatives anywhere in a very long time. Even though I ordered my Bright Eyes headlight new, the product box arrived already opened with a couple missing pieces (diffusing lens and velcro straps for the battery cord). I contacted Bright Eyes to inform them of the missing pieces, and Don was extremely courteous and understanding of my frustration. Even though it turned out to be an Amazon warehouse issue and NOT a Bright Eyes issue, Don was quick and happy to fix the problem. I wasn't tossed around from one person to the next, I wasn't shrugged away. Bright Eyes responded to my message within hours, immediately sent the missing pieces to me free of charge, and kept constant communication throughout the whole process. When the missing pieces arrived, I found that Don included a tail light as a bonus, but I was more blown away by the HAND WRITTEN NOTE. No one does that anymore, and I very much appreciated the time that Don took to write and include it in my package. THAT is how you treat your customers, ladies and gentlemen!! I purchased the Bright Eyes headlight on a whim, and I am VERY glad that I did! Bright Eyes, you have made an extremely loyal customer!!!!!

I have this light mounted on my E-mountain bike, it was easy to install, and in the short time I have had it installed it seems to work great. It is winter where I am, and dark by 17:30 so it was a very welcome addition to my bike. It seems to be a very solid piece and well made, I have not been able to test it's water proofing but I am sure it will hold just fine. I did experience an issue with shipping but the seller was able to get it sorted and made things right.

I waited a while before posting my review so that I could actually use it for a few months and see if any problems turned up. First off, I'd actually give this a 4.5/5, it's quite excellent at the price point, with a couple minor issues. Let's do the pros first: Run time does indeed exceed the 3.5 hour rating, in my testing I get about 4 hours and 20 minutes out of a fully charged battery, running on High the entire time. I haven't tested run time at other levels, but I'm inclined to believe those would be excellent as well. The supplied rubber O-ring mount works fine. Yes, it has the tendency to shift around a little if you mount it as pictured, but the best solution for this doesn't require applying tape and all sorts of things to your handlebars: simply mount it upside down, and the weight of the light head will be as low as it can go, so it won't be inclined to rotate downwards as you ride. I've only ridden once in the rain with it, but during that ride I had no issues at all, with any part of the system. The included beam-spreader (which I haven't actually felt the need for) seems to work well, but I put the regular glass back in. The light itself IS very bright, and it does seem to be using the Cree XM-L2 LEDs, which yes, under factory test conditions can produce up to 1200 lumens. Once you take into consideration losses from driver inefficiency, optical losses at the reflector and lens, heat inefficiency from the LED itself, I would estimate this is running between 500 and 800 OTF lumens. I own a higher-end flashlight with the same LED, and it appears slightly brighter to the eye, but the flashlight has a beam profile that is tighter than the bike light, so naturally it would appear "brighter". I run two of these, one on my bars and one on my helmet, and it's plenty of light. I haven't experienced any failures of the light, switch, wires, battery, or mount. Do note that the mount isn't technically adjustable from side to side, but I believe there is a screw underneath the mount that you could loosen and redo the angle of the mount if necessary. Modes are simple and easy to move through: High - Med - Strobe - OFF, or push and hold a couple seconds to access the extra modes. The secondary modes are remembered until you disconnect the battery. I don't mind too much, since I don't really use the extra modes, but if that's important to you, there it is. The only cons that I've experienced: The green indicator light built into the power button (which is supposed to turn red for low battery) doesn't give you much more than about 30 seconds of notice before the light shuts off. I thought it was supposed to warn at 10% battery capacity, but I've tested it a few times and it definitely goes red less than a minute before turning off. Again, for the price point, not terrible, and since my commute is about an hour and ten minutes, I just make sure to charge after every third ride. If I get stuck on a fourth ride without charging, I'll run the light on medium and keep the helmet light off, and then if the bar light dies, I have the helmet light as a backup. I also noticed once that the battery seemed to drain if left plugged in after being shut off. Now, that could be a coincidence based on it not being charged enough since I only noticed it when I first got the light, and I haven't done any tests since to confirm. I always disconnect the light from the battery after a ride now. Note that the green indicator light was not lit during that first apparent battery drain, which really leaves me no idea what may have caused it, other than the battery was simply low on arrival. I honestly can't remember if I charged it or not, and even if it does drain while connected to battery and switched off, at this price point I can't complain. TL;DR: Excellent battery life, mount it upside down, don't worry about the rain, it's not quite 1200 lumens but still damn bright, disconnect it after you ride, and don't rely too much on the low battery warning/have a spare battery if you're going to be out for 4+ hours.
