The LightStar300™ is the result of years of electrical engineering and manufacturing experience as well as customer feedback. It features high/ low modes, a recessed tailcap switch (to prevent accidental activation and for increased durability), is available in standard gray and high-visibility orange, and is electronically regulated to ensure constant light output. It has logic built in that makes the LED flicker at the end of battery life to alert the user to change the batteries.
The LightStar300™ provides 300 lumens of light output in high mode, and 100 lumens in low mode. Tested against an incandescent flashlight in TerraLUX's state-of-the-art Labsphere, the light output was shown to be 25 times that of a standard bulb.
TerraLUX flashlights, worklights and flashlight upgrades are available through tool distributors, auto supply shops, hardware stores, police and public safety retailers and online.
