Full Disclosure: Coast provided me the G10, G15, and G19 lights in order for me to test them out. But, everything I will talk about here is my own opinion.

10) Thoughts/Why I'd Go With The A5 Instead
The Individual Topics Begin Here:
Note: I'm only going to refer to a single light as all three lights are basically the same. Everything mentioned is applicable to all three light unless specifically noted otherwise.
1) G10 vs. G15 vs. G19:
• These three lights are identical. The only difference is their clips
• The G10 has no clip
• The G15 has a mounting clip able to clip onto objects and allows the light to be swiveled in different positions
• The G19 has a normal pocket clip
• All the clips are removable and interchangeable between any of these three lights
2) What I Don't Like:
• I wished they were all a bit brighter
• The beam isn't quite uniform. The perfect circle of light it creates is brighter towards one side
3) Build Quality/Overview:
• The light feels premium. With semi-coarse knurling, it feels nice to hold
• It is entirly made of high strength anodized aluminum
• The tail cap unscrews in order to remove the battery
• The button is a high travel, stiff, mushy, high positive tactile button with a rubber cap over it
4) Weight:
• 1.38 oz (39 grams). That's about the weight of 7 United States Quarters
5) Opperation and Modes:
• The operation of the light is controlled by one button on the back of the light
• There is only one mode
• There is no momentary on mode
6) Charging Port:
• No charging port built into the light itself. Instead, there is a Micro-USB charging port built into the optional ZX100 battery
7) Battery and Charging:
• The light is powered by 1 alkiline AAA battery. It can also run on the Coast ZX100 lithium-ion rechargeable battery
• The ZX100 battery is a standard 10440 battery
• The ZX100 has a built-in Micro- USB charging port and a charging indicator on the top of the battery
• A solid red light indicates charging and a solid green light indicates the battery is fully charged
8) Performance On Lithium-ion Battery:
• I didn't notice any performance/brightness increase when running it on the optional ZX100 battery compared to an alkiline AAA battery
9) Charge Time/Battery Satistics:
ZX100: Rated Capacity: 200 mah Tested Capacity: 164 mah
Built-In USB On Battery: Charge Speed: 310 mah Time: 36 minutes
10) Thoughts/Why I'd Go With The A5 Instead:
Overall, I think these lights are very handy. They are tiny and very unobtrusive. The G19 is perfect to keep on your belt. The G10 is a great light to keep in a purse or go bag. The G15 is a great light for automotive or as general work light as you can clip it on a hat or objects. I wish all three lights were a tad brighter though.
For me though, I'd actually go with the A5 pen light over any of these. The A5 is a tad smaller than these three lights both in height and in diameter and made of higher quality materials; stainless steel compared to aluminum. The A5 also has a much more even beam. Although, its one down side is that it isn't fully compatible with the ZX100 or other 10440 batteries. Some of the A5 lights aren't able to accept the ZX100 as the battery is too tight and gets stuck inside the body. That isn't the case for all of them though. Some A5 lights are able to fit the ZX100. I prefer the A5 regardless as I think it has a much classier look and feel.

Hello,
We're sorry to hear your light isn't working sometimes. If you would like, go ahead and follow the link below to access our Warranty Request Form. You can warranty out your current light for a brand new one!
Received a free replacement for the flickering light. New light came with a slightly defect lens but I could reuse the lens on my old light so putting the two together I have a new light once more. Thanks for your good warranty service.

Handy little light, use it daily as my edc. Takes up almost no space in my left front pocket. Had the older model that saw daily use for the past 5 years. Coast sent me a new G15 under warranty and this new model has a better bulb and beam pattern and is slightly longer. Wished the new model had a lanyard hole but on the plus side Coast offers an optional rechargeable battery for it. Coast has a great warranty. I own 3 Coast lights altogether.

GREAT FOR AIR TRAVEL

I fly a lot and I often drop things! The G15 is great in that it has a bright concentrated beam and doesn't disturb other passengers. Always by my bedside in hotels. With the clip I use it as a reading light and sometimes a work light in hotel rooms. Wouldn't leave home without it.

I carry this little, but powerful flashlight on my key ring so it's with me always. It helps me see the keyhole at night or find the candles when the light goes out. What is more impressive than the flashlight is the Coast warrantee. Mine stopped working, after years of service and they quickly replaced it with a new one. No questions asked. Great light and great service. what else can one ask?

Neat pen light comes with a clip if working with a hat just clip it on. Strong and clear circular light for when you need to inspect something quickly and need more pinpoint focus.

Great for bus drivers, and fishing

Casts a fine circle beam, for reading bus stops and route without blinding you ( actually almost a little too bright) clips to clothing or sun visors well. The fishing is perfect bright enough to tie knots and remove hooks.
