TerraLUX TLE-ST is the World’s Best and Brightest Upgrade suitable for use in the Streamlight® Stinger® and Stinger XT® Flashlight The huge base of Streamlight® Stinger® flashlights with incandescent bulbs can now enjoy the features and cost-saving benefits of the TerraLUX LED Light Engine® in a custom engineered upgrade. Featuring the CREE XRE Q4 Bin 220 Lumen LED, the unit delivers reliable, constant brightness thanks to the unit’s integrated electronics. The product features a patented* design that includes a heavy-duty heat sink that ensures a cool-running LED. This means the unit does not experience significant temperature induced “fade” found with inferior designs. The high efficiency of the LED means that the user enjoys a much longer runtime,-approximately 120 minutes (continuous) between charges. Because the battery undergoes fewer charging cycles, battery lifetime, which is determined by the number of charge-discharge cycles, is greatly extended. The unit literally pays for itself in batteries and the light bulbs that do not need to be replaced,-not to mention reliability.
