Everything you ever wanted to know about the Light Center
Do I need to do anything before I use it?
For best results, the battery requires a conditioning charge before first use, or after long periods without use. This can be done by administering several vigorous 30-second wind cycles. Alternatively this can be done by fully charging the battery using the wall adapter (if you have one). The product can, however, be used immediately in the wind-up mode if required.
How do I change the light bulb?
The light is an LED (light-emitting diode) with up to 100 000 hours of useful life and never requires replacement.
How long will a fully charged battery retain its charge?
The battery will retain about 75% of its capacity after 1 month, 55% after 2 months, 40% after 3 months and 15% after 6 months.
Can I over-wind the unit - does it ever stop you from winding?
No, you cannot over-wind the internal mechanism. It consists of simple gearing which drives the alternator, providing power to the internal battery.
Will I damage the product if I crank the handle in the opposite direction?
No, the winder handle can be cranked in both directions.
Is the product waterproof?
No, it is not waterproof. It is splash proof and will work in rainy conditions.
How long should my Sherpa LED shine for?
With a fully charged battery the Sherpa LED will shine for approximately 20 hours in energy saving mode, or 3 hours 20 minutes at full power. A 30-second wind will provide about 20 minutes of shine time in energy saving mode, if the winder handle is cranked at the optimum speed. This will be achieved as soon as the green charge level indicator next to the winder handle illuminates.
How long does it take to fully charge the battery?
Using the wall adapter, it will take about 24 hours to fully charge the
battery. Or using the crank, it will take about 40 minutes, if you constantly
wind at the optimum speed as indicated by the green charge level indicator.
The battery doesn't hold a charge any more; do I need to replace it?
Rechargeable batteries deteriorate over time, especially if drained nearly completely (to extend the life of your battery, limit how often that happens). However, in many cases they can be "conditioned" back to life. This can be done by administering several vigorous 30-second wind cycles. Alternatively this can be done by letting the product run from the battery until it stops, and then, with the product turned off, fully charging it using the wall adapter.
