Do not purchase this light. Faulty battery assembly!

I took this out on a night ride through the woods with a full charge. Within an hour the battery indicator was at the third LED and blinking. This is claimed to be 3 hours on full charge with full output. Definitely did not happen, had to limp out of the woods with a failing light.

I bought cheap lights before and they have lasted me the full 3 hours and then some. Same battery pack configuration. I decided to remove the casing and plastic to see what the problem was. These batteries are 18650’s just like in many other applications (Mechanical e-cigs for an example).

The first attached image is the battery pack that came with this light. The batteries are supposed to be wired in series to get maximum battery life without having a large pack (essentially one large battery). To have them in series you have to have the positives of two connected to the negatives of the other two. If you look in the picture, two batteries are not even soldered. Then, if you look closer, you’ll see THREE positive terminals. That’s not series or parallel, it’s just wrong. In this setup, at the worst it could explode, at the best i’ll get the battery life out of two batteries, not all four. Which is what happened. Also notice they’re different colors, from different manufacturers. Even as a kid we know not to combine different types of batteries. They charge and discharge differently, report voltage differently as well. Charging this setup could pose a fire/explosion hazard.

Look at the second attached picture and it’s from the other lights I purchased a while ago. Four same-color-same-manufacturer batteries wired all four together. Two negatives, two positives. Ignore the yellow stuff it’s glue from the end cap. This is a correctly assembled battery, and I get the full 3 hour discharge as advertised. I’m also not worried about this one exploding. Will not buy another one of these batteries.

You’ve been warned, if you still purchase one of these take some of this advice and check the battery pack configuration before using!

This past summer I purchased a Brighteyes 1200 lumen biking light that uses CREE LED lights. The Brighteyes light is bright, but I wanted more light so I searched Amazon and found these 5000 lumen lights. Well I thought with 2 LED’s, this light should be a lot brighter than my 1200 lumen single LED light….WRONG. The SIGA is about 1/2 as bright as my Brighteyes. In fact, on low, my Brighteyes are still brighter and whiter than the SIGA on high.

My next light will be a RioRand. It uses the same CREE light as my Brighteyes and the same advertised lumens. It looks exactly like my Brighteyes, but at 1/2 the cost.

Edited to add:

11-15
I charged the battery pack and tested it for time. At full brightness, the battery pack lasted 1.5 hrs. In the description it should have lasted around 3 hrs. I’ve read that some of these battery packs are not wired correctly, so I disassembled the pack. Upon inspection, wiring was defective. Two of the batteries were not wired to the pack. Battery pack is now charging with correct wiring.

11-16
After correct wiring and charging the battery pack overnight, I tested it again this morning. It is as bright as my other light, more diffuse light, but just as bright. However, the battery only lasted 1.75 hours. I will test it with my “Brighteyes” battery pack to see if it is drawing that much or if it is just the batteries.
