Battery Powered Lights (BPL) :
1. Kept In The Dark:  Batteries run out, usually when you need them most!
2. One Man's Trash Is Another Man's Landfill:  Where did you think those old batteries went?
3. Turn Off the Lights When You Leave:  BPL's need to be physically switched on/off each time.
4. Keep the Change:  Batteries cost both you and the environment.
5. Beware Thieves:  Portable BPL's are very easy to be stolen.
6. Don't Forget #3:  In most cases, the batteries' power is wasted by leaving the lights on after use them.

Traditional Dynamos:
1. Check Your Tires:  The tire scraping with traditional dynamos gives new meaning to the term "What a drag!".
2. Lighten Up!:   At very slow speeds, the lights go dim.
3. There She....:   At very high speeds, the bulbs can blow.
4. He's A Slippery One:   Generators can slip in the rain, just when you need those lights the most.

Solar Powered Lights (SPL):
1. All Your Eggs in One Basket:  If dark (raining) days continue, SPL's may lose power.
2. Charge It:   Who has time to wait for these to charge?
3. Outdoor:  SPL's must be left outdoor for many hours in day time to charge the batteries.

Early "Magnet and Coil" Designs (Since 30s')
Many people thought this new product was just more of the same. But they were wrong!

Earlier designs were made up of something like a stationary coil with lights installed on bicycle, with a moving magnet installed on the wheel.As the wheel is turning, the moving magnet passes close to the coil and generates electricity to power the lights. In theory, those early designs are very simple and should work, but in the real world they do not. Why is this?

1. On bicycles, the gap between a moving magnet on the wheel and the coil is often changed, because of the structure of bicycle wheel. In those early products, the "gap" must be no more than 3mm, otherwise its power output will reduced dramatically. It is very difficult to keep precise less than 3mm gap on a bicycle. This new product overcame this problem, the "gap changing" between 0.3cm to 1cm will not effect the power output nearly as much.

2. The early designs often use large moving magnets on the wheel in order to get enough power output. Because of the weight of the large magnets, eventually 2-4 large magnets had to be installed on the wheel to keep the wheel rotating in balance. On this new product, only 2 small moving magnets (25mmX5mm block) are installed on the wheel. There is no balance problem and does not distort rotating of the wheel.
