NightStar is the original renewable energy shake flashlight – AIT invented the technology!

Independent tests and facts are clear about NightStar's superior performance.

When compared to the competition NightStar has:
• more light output

• greater durability

• reduced shake time

• longer operational life

• increased performance at high and low temperatures

• advanced technology

NightStar is the market leader. Save yourself the headache – buy long-lasting peace of mind … buy the best!

** NightStar was the world's first renewable energy flashlight. It was invented in 1997 and went into production in 1998. NightStar was issued its first patent in 1999. In 2001 it was issued its second patent for the magnetic recoil charging system. Using magnetic repulsion to rebound the charging magnet is far more efficient and quieter than springs. The spring rebounding system was used in the first NightStar flashlight because of cost considerations. The Forever Flashlight, EM Energy Flashlight, Eternity Flashlight, Everlight Flashlight, Hummer Flashlight, and Lifetime Flashlight are all functional replicas of the first NightStar and as such still use springs and rubber bumpers. The Freedom flashlight uses 2 coin-size Nickel metal hydride batteries rather than a capacitor. Using batteries has the disadvantage of a significantly shorter operational lifetime and reduced performance at high and low temperatures. With the batteries however, the Freedom Flashlight will initially run the LED for two hours but will require approximately 18,000 shakes to recharge (nearly 1 hour and 40 minutes of shaking). The EDI-T flashlight is a near identical copy of the current NightStar except that it uses inferior components. As a consequence, the EDI-T flashlight produces far less light, is not as durable, and requires twice the shaking time to recharge the capacitor.
