Most Helpful Positive Review Jeremy Ritchie,when the power goes out you can light up the block with this new hp21
This is the Mack daddy of lights I was really impressed with the output. It to me is a little overkill if you just need a flashlight but I like to see my surroundings and it will light up a big area so there is never any surprises in store at least for a area of 100 ft around you at any point. So if you are looking for a flashlight I would say the coast hp14 would be great but if you are looking for the sunshine get the hp21 turns the dark into day. Pros: super bright, strong feel, quailty workmanship to say the least Cons: little exspensive

The Brightest Flashlight Ever!

by ZaDoc, from FL, United States Written on January 16, 2018
I bought this beauty a few years back. I said of relatively new Duracell batteries leaked into the flashlight, causing extensive damage to it. I sent it back to Coast, and they sent me a replacement in no time flat. Truly AMAZING flashlight which lights up the night! Incredible warranty by a very reputable company. Although it’s discontinued, I would purchase ANYTHING that would come even close from Coast if I had to replace it. Hands-down, the absolute BEST flashlight I ever owned in my life!
Pros:
  • Super bright, extremely durable, and easy to carry.
Cons:
  • none!
Best Used for:
  • Anywhere were that you need extremely bright lighting
  • Anywhere that you need extremely bright lighting.

Wow, a Great flash light but it is BIG!

by Legacy Reviewer, Written on January 19, 2013
A supper flashlight if you want high output and a club or defense weapn. Built to last however the focus system needs improvement as it won't stay adjusted if you move the light or stand it on end.
Pros: Super bright, well built, should last for ever
Cons: BIG, Heavy and focus won't stay as adjusted
Would recommend: Yes

Great Flashlight

by Legacy Reviewer, Written on July 8, 2012
Great Flashlight. I was looking for a bright flashlight for when I am out in the water with my boat. It works great. I was actually able to see a bit under the water at night with this thing. The Flash is alsp great to bling someone for a moment if you need it for that as well.
Pros: Bright, Durable, & Easy to Use
Cons: Switch from Bright to Flash
Would recommend: Yes

Very bright light!

by Legacy Reviewer, Verified Owner from IN, United States Written on December 20, 2011
This light is very bright and with a focusable beam to spot or flood, it's a winner! The cost is very reasonable compared to other lights with the features of this light. It might be slightly heavy due to the 4 D cell batteries, but nothing that heavy for the amount of light it puts out. It does come with a carrying strap if weight is an issue. It is a well built light and I love it!
Pros: No special batteries(D cell), Extremely bright, Focusable
Cons: None
Would recommend: Yes

Awesome Flashlight

by Legacy Reviewer, Verified Owner from MS, United States Written on December 10, 2011
This is an amazingly bright flashlight! I have a Terralux 600 lumen bulb for my 4D Maglight and This HP21 blows it away! When I looked at the original packaging (no users manual), it said that I shouldn't mix alkaline, nicad, nimh, or lithium batteries. After trying the 4 alkaline batteries with good results, I inserted 4 Tenergy 10,000 mah batteries and ended up frying my light. (Im quite sure this light is unregulated) I called Coast and told them what I had done. They though that I had a defective light. I got a replacement, and this time after reading some advice on the internet and speaking to someone at Coast, I inserted 3 of the Tenergy 10,000mah regargeable batteries and a D-cell spacer, and have not had any problems. The HP21 is actually a little brighter with the 3 Tenergy 10000mah batteries than it was with the 4 alkaline batteries! I believe my hp21 is actually brighter than the headlights on my 2002 Ford Taurus! After comparing it to my Brinkman 3 million CP Spotlight, i think that if the HP21 focused down as tight as the Brinkman, it would be close to as bright. Im a very happy customer!
Pros: Very bright with 3 rechargeable batteries!
Cons: It doesnt focus down as much as I would like. I guess if it did, it would be a spotlight!
Would recommend: Yes
