The light that won't give you away!
The G20 is great little light for work or play, unobtrusively rides in the pocket or inner waist band for concealment. A good feature not to many think of in a light is a lower lumen concentrated beam like the G20, it doesn't draw the attention of a would be 1000 lumen beacon. A nice little light

Love it but ..
I've had this light for a year I use it while fishing at night . It's absolutely perfect. I use whenever needed and it's perfect when working on car and you can't see something, this bad boy pinpoints the spot you want . But only thing I've came across is I didn't know the bulb would go out . It's got brand new batteries in it and it won't work. But I absolutely love it.

    Great little pen light.
    I had a G20 sometime back and gave it away. I seen I could buy the rechargeable battery for it so decided to get a couple more of them. Now I have a light for in the house when needed. I can say the G20 is a great little pen light, dependable gives off very good light. My wife decided she was taking one of them to have in her purse. Coast lights have always been a trusted product in our house, at work and outdoors. My wife says I have a Coast fetish because of all the different Coast products we have! I have only needed to use the Coast warranty twice in all the years of owning them and I can say that they stand behind it. Very good service and totally professional. I’m happy to say I will be a Coast customer for a long time to come. Thank You Coast!

      Dual power option
      Confused cant seam to find the zithion-x that fits the g20. Is it not available yet or is my packaging wrong and its not an option?
        Faulty led connection
        I’ve had 3 of these the construction is good, however the seal for the bulb end is not very good all three corroded and work intermittently. Easy enough to open up and clean it up however I feel I shouldn’t have to. The latest ones button tore open so I’m sure the switch won’t last long exposed. Mind you this is normal use never submerged I’ve only had this one 2 months.

          bright and sturdy
          Great solid light, good weight and really bright. Wasn't expecting to be so bright for a compact light. I like that the pocket clip can be installed on either end of the flashlight. So many times i have bumped the power switch and drained the batteries because it was pointing inside my pocket but not now I can have the on button in my pocket and then light facing out knowing that the light is on or off.

          G20 capabilities
          I work in the oil and gas industry (robotics division) and wanted to test this light at depth while bored at work, so I strapped it to the sub and sent it down..... to 710’ still working for approximately 41 mins at depth. got the sub back on deck and just cleaned with contact cleaner and 2 fresh batteries and still works great!!!
