## Questions & Answers

**Q: I have a different manufacturer led bike light (serfas true t1000).  can i use this battery as a backup battery?**
A: Check the connection type and voltage rating.

**Q: What brand and model of battery is in the 6400mah pack?  if it is really 6400mah, you should publish this data.**
A: His question is legit and you did not answer it honestly.  You were asked who makes your battery.  Lets be more specific.  Who makes the 18650 cells?   Your do not make 18650 cells.  So answer the question by: BAK, Samsung, LG, Panasonic, or no name generic.  There are many 18650 cells made in China and India that are no name generic that are junk and come no where near a capacity of 6400 mah (x 4 cells) and if that is what you are using, you should not publish that.  BAK is a Chinese 18650 battery manufacture that is not up to the quality of the others mentioned and again should be clarified.

**Q: I bought this battery but it flashes green & red when I plug it into the charger (and doesn't charge). Is it my charger or the battery at fault?**
A: I've also seen the flashing LEDs when dirt and/or corrosion needs to be cleaned off the terminals. I've found this particularly irritating for the battery pack terminals made out of garbage-cheap alloys. Any corrosion and it can screw-up the monitoring processor in the charger.

**Q: Could someone tell me the power output of the charger?**
A: Good question. In this case we are talking about the 1200 lumen light from Brightteyes so power of the light is given. I believe what is being asked here is what are the power and voltage rating of the wall adapter that comes with this offer.  This information must be stamped on the label or silkscreen print on the adapters enclosure.   I second your question. If anybody can read this from the label. Please answer.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality Product with Exceptionally Responsive Customer Service
*by C***S on January 7, 2021*

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!

### ⭐⭐⭐⭐⭐ Let there Be LIGHT
*by J***F on January 11, 2022*

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!

### ⭐⭐⭐⭐⭐ Nice retrofit
*by R***N on February 16, 2024*

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.
