The arc tested ASFL FR task light features a high intensity long lasting white LED lamp with an overall brightness of 35 lumens. From a 24 inch distance, the beam is approximately 6-7 inch in diameter. The high intensity illumination is very useful when working up close. 2 AAA batteries provide 14-15 hours of high brightness. NOTE: The AS1200HAT can hold 2 ASFL task lights. The FLKIT only contains 1 task light and 1 clip.
