Personal Experience

I’ve been using the Speras S11 for a while now, and I’m really impressed with its versatility for its size. Here are some highlights:

  • Brightness: 400 lumens is plenty bright for everyday tasks like finding something in a dark bag, navigating a dimly lit hallway, or checking under the hood of your car. The high mode is particularly useful for short bursts of bright light. You just have to push the button an the light starts. When you release the power button it is shut of.
  • Multiple Modes: The main light with multiple modes and the multi-function sidelight provide a surprising range of options. The UV light is handy for checking for counterfeit money or spotting pet accidents. The red light is great for preserving night vision or as a discreet light source. You can easily switch between these modes by doubble tapping the power button
  • Portability: The keychain design and lightweight build make the S11 a perfect EDC flashlight. I barely notice it on my keychain, and it’s always there when I need it.
  • Durability: The construction feels solid, and the IPX65 water resistance gives peace of mind in case of rain or accidental spills.
  • Rechargeable Battery: The built-in USB-C rechargeable battery is a big plus. No more hunting for CR123A batteries!

If you’re looking for a compact and powerful light source to always have on hand, the S11 is a great option. I always have it with me and use it almost every day. I don’t want to miss it anymore
