Product Overview

The G450 Flashlight uses Coasts Pure Beam Focusing Optic System with Twist Focus to harness the light and create a superior beam quality from spot to flood. The Bulls Eye spot beam pattern gives you a great focused spot while producing an outer ring of flood light which allows you to see a broader area to the sides. The flood beam is broad and consistent, giving you a clear field of vision not seen with typical focusing flashlights. A quick cycle switch allows you to select light output settings with ease. Built tough, an impact-resistant, lightweight aluminum casing resists rust and corrosion. The G450 also features an unbreakable LED and rubberized O-ring for reliable water resistance and durability. With Coasts commitment to quality, the G450 Flashlight is impact resistant, weather resistant and its LED is virtually unbreakable. The G450 Flashlight is backed by Coasts lifetime warranty against defects in materials and workmanship. Tested and rated to ANSI/FL1 standards.

Works day in day out. Used it all through the Texas freeze with zero issues. Heat kills batteries so leaving in the car in the Texas sun will do the light dirty. Have used it in sprinkles but not heavy rain yet as Coast has weatherised lights for that. Lenser design works great as well as ample lumens to do most any job. I am rough on lights so if ive bought 3 or more its because i wore them out from work...not any reflection on the world class,top dog builds. I do depend on these for critical situations involving lives and expensive properties among other things so this is my shtf out the door..got to get it done light.

Make sure to check battery pack often
This was replacement for the HP550. The battery pack froze up in that flashlight. So I get sent a replacement G450 and guess what the battery pack was all corroded when I went to get it out. If I hadn't checked it.....it would have been same situation as old HP550. Not sure if a design flaw in these flashlights, but I'm done with coast. I was a firm believer they were the best flashlight.....not so much anymore!!

I use alot of flashlights both on the job and off but I have found that Coast lights tend to be the most financially reliable. I have relied on my H550 to get through many a tough call but now my G450 is even better with higher lumens and longer battery life I am impressed. I totally recomend these flashlights for what ever job your doing that needs a brighter touch.

It's a bit heavy and quite large so handling it is more difficult than a smaller flashlight would be, but the enhanced brightness makes it my first choice while walking my dog. I've added a strap for added security in holding it. I think it would be a better product if Coast provided one in the package. I've been using it exclusively with eneloop batteries and the performance has been great. I know Coast doesn't recommend using them, but so far (22 days - daily use) I'm still on the first charge and I haven't noticed any loss in brightness or any other problem using them. Once I understood how to use the power adjustment I became a fan of it. You just partially press the power button until you are at the power level you want and then push it all the way to lock it on at that level. It took me a more than a couple of days to figure that out. Maybe that will help some else. I also use the flashlight in the highly focused mode. The spill over from the central spot seems useful to me though to each his own with regard to that. I like that I can have a look at what my dog is up to without needing to blind him with the central hot spot. I'm very pleased with the HP450.

Excellent flashlight if you want a powerful beam (and a small club). This throws a very bright beam if you are willing to carry a slightly larger than average flashlight. At distances of 30ft or so the difference between the spot beam on this flashlight and something a little smaller such as the Coast PX1R 460 Lumens light is not terribly obvious, however at 50ft or more this flashlight really throws out a lot of light even when the beam is set to the flood position. It also has a lower power setting which will extend the battery life and still throws out adequate light at up to 30 ft or so on the flood setting. See the attached pictures to get an idea of the strength of the beam. I would say the only downside is that it is a little bulky (it is about 9" long) and fairly weighty since it has 6 AA batteries. It does seem well made and solid like it would survive being dropped quite a few times.
