What owners report

Streamlight ProTac 2L-X

  • Runs on two CR123As or a single 18650, with better runtime from the 18650
  • One owner reports three and a half years of hard use with no wear
  • Light for its durability, resisting both impact and water
  • Streamlight's warranty and reputation behind it
  • Wide beam pattern suits close-range work well
  • Output drops after fifteen minutes and settles around 350 lumens, not 500
  • Scattered reports of flickering and failing to switch on with fresh cells
  • One owner's dimming issue only resolved by using a genuine Streamlight cell
  • The wide beam wastes the output at distance
  • No high-CRI option

Streamlight MicroStream USB

  • Slim and light enough to carry daily without noticing it
  • Hold for momentary, click for constant — the right interface for the size
  • Streamlight's lifetime warranty
  • USB rechargeable, so no cells to buy
  • Genuine performance for a pen-format light
  • The button needs unusually high effort, especially for constant-on
  • The pocket clip is weak
  • Heats up quickly even on the low setting
  • The focusing lens makes almost no difference to the beam
  • Micro-USB charging on older stock
