Bright EyesThe Best Bike Light Battery - Now Higher Capacity - Works with CREE T6 LED 1200lm Bike Lights - 8.4v

used this in rural Lake Anna Virginia State Park at an ultra triathlon where it is so dark, "you can't see the end of your nose" kind of dark. In the middle setting, it was FANTASTIC and battery life outstripped my expectations. The amount of light was almost too much, I needed to ensure that the light was appropriately aimed but I had as much light as could be had to see (both) sides of the road as the biggest hazard was deer coming from either side.This is a 2nd generation purchase. I picked up my original many years ago (2013?) and this one went to my daughter as I'm still happy with my older light, even though it's less bright and eats the battery a little more quickly. Support for existing products is unbelievable -- after getting support for such an old product made the decision to pick up this light for my daughter a "no-brainer".Best improvement, for me, was the newer lights have slightly shorter cable lengths and have re-arranged the layout -- I'm sure based on customer feedback. More companies should work like Bright Eyes!

This battery pack works just fine with my current light which I’ve had for 10 years or so. The old pack finally gave out, so it was time for new one.I was pleased to find a replacement that would fit, and as an added bonus, it has a longer rated running time.In my case, I just sort of crammed it into my original pouch. It was a slightly tight fit, but it works just fine. So I’m back in business with a nice, bright light.The price is reasonable. The connector matches so installation couldn’t be simpler.I do recommend it.

I've been using the Bright Eyes system now for many years. I find that a battery lasts about a year and needs replacing. It isn't too expensive so I'm very happy. However, the latest battery that I received, in April, 2022, is not holding charge well. It runs for about a little under an hour on high. I can usually get about four hours. I'll need to contact customer service, any ideas on how to do that? Thanks, Dennis.

I bought my second Bike Light from Bright Eyes this Christmas when I noticed there was a new 1800 Lumens light. I’ve been so happy with their 1000 lumens light over the years, that I decided to upgrade to a brighter light since I ride a lot at night.When I opened the box of the new light had lots of extras, including 2 ways to mount the light on the handlebars. Unfortunately, the small adapter that connects to the light and the the bike mount was missing. I mounted to the bike using the other device provided, and it worked well!I wanted to use the other mount since it was taller and it fit my bike better, so I emailed customer service on the day after Christmas. Don replied to me the next day, apologized, and sent me the replacement part immediately. I received it very, very quickly. It worked perfectly. Don from customer service had also asked me to respond to his email and let him know that I received the part. When I notified him of receipt of the part, he replied back and thanked me. He offered additional help if needed.The light itself is very bright, well-built, sturdy, and performs well. The battery is in a solid case and very easy to mount. I would rate it 10 out of 10!I highly appreciate a company that cares about their products and their customers! That’s rare these days!

This was a replacement for a very similar looking battery pack that after 10 years no longer held a charge. This pack gives me around 2+ hours of full power on a Cree style headlamp.The velcro mounting seems quite secure. The wiring harness is kind of long and requires dressing to not look like a rats nest.If this lasts another 10 years then I've definitely got my money's worth.The picture shows full brightness after full power for 90 minutes.

Won't charge at all. And no power is coming out of it. I have used it maybe five times in six months and charged less often than that and it just stopped working

good All around light w a high quality light and battery

I've used these lights and batteries for quite a few years and have always been pleased with their performance.

straps are too long good charge life and performance get 2hrs on high
