Q. What is the difference between the CREE XM-L2, CREE XM-L and the SSC P7 D-Bin LED emitters?

A. They are similar products produced by 2 different companies. CREE Inc. is headquartered in Durhan, NC USA, with production mainly in China. SSC or Seoul Semi-Conductor is headquartered in Seoul South Korea with production also in South Korea. The SSC P-7 LED has a maximum output of 900 lumens. The CREE XM-L has a maximum output of 1000 lumens. The XM-L2 LED is CREE's latest generation and produces up to 20% more light than the XM-L while using the same about of power.

Q. How do I choose which light is best for me?

A. To help you in your selection see our Bike light Comparison Chart. and/or Beam Patterns

Q. Can I use your lights with a Dynamo Hub?

A. A high quality dynamo hub like the Schmidts SON hub reaches a maximum of 3 watts @ 6V at 10mph (less at lower speeds). Of the lights we sell, the one with the lowest power requirements is the Gemini XERA. It requires 1.23A @ 7.4V or 9.1 watts at 100% brightness. It also requires at least 6V to operate. So unfortunately you would only be able to run the light at 30% power and not until reaching 10mph.

Q. Can I charge my battery with a Dynamo Hub?

A. To charge any of our batteries requires 8.4V so you would first need a DC to DC step up circuit. With the 3W, 6V maximum output of most better hubs (at 10+mph) and an 80% efficient conversion to 8.4V you would have a charge current of .28A. At that current it would take at least 10 hours to fully charge a small 2 cell 2.2Ah pack.

Q. Which battery is best for me?

A. First, all of the batteries we sell will work with any of the lights we sell. The one to choose depends on the length of your rides, the light or lights you are running, how rough of use it will get, and how weight conscience you are.
The mAh rating is a measurement of the capacity of the battery pack. A 5400mAh pack has 23% more energy stored in it than a 4400mAh pack so your run times will be 23% longer. If a light comes with a 4400mAh battery and has a 3 hour run time if you use a 2200mAh pack your will have a 1.5 hour run time and a 5400mAh pack will give a 3.7 hour run time.
The final factor is quality. While all the batteries we sell are UL rated and very good quality, the Panasonic and Samsung batteries will provide longer life in years or number of charge cycles.

Q. Can I replace individual cells in my battery pack?

A. First, all of the hardshell packs we sell are sealed shut and cannot be opened.
Replacing cells is not as easy as it may seem. For the cells in a pack to all charge properly they must be very closely matched otherwise one cell may get over charged while another is not fully charged. There are 2 problems with this. A Li-ion cell that gets over charged or over discharged can become unstable and explode or catch fire. To protect against that the pack has a protection circuit in it that monitors the voltage of the cells and shuts off the discharge when any cell in the pack (or parallel pair) reaches 2.75V. It also shuts off the charge at 4.2V per cell.
Because of that the strongest cell controls the charge and the weakest cell controls the discharge and as the pack is used the imbalance between cells become greater with each cycle.
The only way around that is to use a battery holder that uses 4 individually protected 18650’s and charge each cell independently. Then you would need a 4 place charger or 2 of the 2 place ones we sell.

Q. I want a different battery with my light than what comes standard. Can I trade?

A. Yes, there is an option in most of the listing to upgrade the battery. If you would like a combination that is not listed contact us and we'll put together a custom package.

Q. I am a member of a club. Can we get a discount on a group order?

A. Put together a list of any combination of lights and accessories you are interested in and we'll give you a quote. Discounts start with a purchase of 5 lights.

Q. Do you ship Internationally?

A. Yes, we ship worldwide. Put the items you are interested in into the cart and in the first page there is a shipping calculator that will give you all your carrier options.
