2000 Lumen USB Headlight

Hi All,

First off I want to thank everyone for their help over the last few months, including cellman, who was patient and helpful as I placed my order for a triangle battery pack. What I've realized is a simple ebike turns into a small obsession, adding parts here and there. With that being said, here is my quick review of a USB headlight.

I was looking for a way to have a nice powered headlight, with my first choice being a light that plugs into my CA directly. After looking at the prices, I finally realized that a cheaper alternative would be to just use a USB light with a free powerbank I got at a recent technology convention.

Below is a 2000 lumen headlight I got off ebay for about $12.

I use a very small powerbank with the following specs:

Input: 5v-800mA
Outpu: 5v-800mA
Capacity: 2600mAh

Mounting it to the front of my handlebar, and running the powerbank into the center frame bag couldn't be more seamless:

To be honest, 2000 lumens is a bit much, so I run it at the second setting, which dims the light to about 1200 lumen at about 1500MA (current). The light lasted exactly 2 hours and 22 minutes, which seems to befalls awesome considering the quick setup.

For those looking for a decent light and don't mind charging a removable USB powerbank every few days, this is a great alternative to an integrated CA light.

Enjoy!

Nice... I picked up something similar (headlamp that comes with battery pack and charger) off ebay :

So when I charge my battery pack I can charge the light as well. The batteries used are standard 18650 batteries (cheap rechargeable) so I can stack them in parallel or swap them out when I need to.

Yeah i got that USB version myself. I never thought for the low price it would be so bright.
i get the odd bit of words from ppl on the street.

This video below at 24 seconds, guy drinking a beer says "What do you use at night time?" as light was beaming them when i first turned it on..

You can also use a dc to dc converter to power the headlight from your battery pack. I use a 36v to 12v for my headlight, but 36-72v to 5 v would power your head light.

The Banggood ones have the DC/DC converter included inside the light. Shortly, I'll be able to tell you about this one that can take any voltage between 8v and 84v. It has the Cree U2 emitter:
