The TM120L is part of the Tradesman range, having only a single sided Light Head. Rather than the double sided head that the Industrial series has. It produces 1030 Lumens of light and the TM120L operates continuously on a single charge for up to twelve (12) hours. The TM120L is powered by a 10AH Lead Acid Gel Battery which takes only 7-8 hours to fully charge. Included in the light is a mains on / off switch that is designed to help increase the battery life as it can be easily turned on and off as required.
