Powerful Unique LED Lighting

Streamlight's Twin-Task 1L is the perfect every-day-carry flashlight that will get you through your work day. There are several types of jobs that will require you to have an accessible light at the ready. What makes the Twin-Task 1L the best hand-held light is the three unique light outputs which include: spot lighting for long-distance illumination, flood lighting used for smooth up-close tasks, or a combination of both outputs that will provide you with all-encompassing lighting for tasks that may require both kinds of outputs.

Decent general purpose flashlight.
October 3, 2017
Much larger and heavier than I expected, but well constructed and durable. It does what it is intended to do, push the button and it lights. There are 3 modes to chose from, high @ 240 lumens, spot/flood mix @ 200 lumens, and flood @ 60 lumens. Decent, not great runtimes but will get you by for about 6 hours in flood mode, 4 hours in the spot flood mix, and about 2.5 hours on spot. Have an extra battery on hand just in case.
The 60 lumen mode isn't as bright as I expected it to be as compared to other 60 lumen outputs of other flashlights I've seen. However, it is a flood light shedding it's light over a greater area than most other flashlights of the same lumens. It will light up a 16x12 room, not real bright, but enough to see completely what you are doing in a power outage. It's almost like a battery saving mode.
The spot/flood combination puts out some good light. Much much brighter than just the flood light. However, the beam isn't as spread out as the flood mode is. Its much tighter beam. Has a decent throw too. This mode is more like a general purpose flashlight would be but at 200 lumens which is much brighter than most general purpose flashlights would be.
The spot light is about what I expected it to be, but could be better. Has a decent thow, around 50 yards max of useful light. I've seen better out of a 240 lumen flashlight, but this isn't bad. Not exactly for search and rescue, but the spot/flood combination or the spot are good for around the block in your neighborhood. A good general purpose light.
Overall not a bad light.... but nothing great about it either. I don't think I'd EDC it, but not a bad light for home or around town.
  • Solid construction, durable. Multi mode lighting. Good general purpose light.
  • Larger and heavier than one would expect from looking at the picture.
