Product Overview

Jumping up to AA batteries, the HL27 Headlamp not only goes up in brightness but also has the light dimming on the front of the headlamp to keep all the controls in one convenient place. It gives you the ability to shine an ultra wide flood beam and then quickly twist the bezel to a long reaching spot beam with transition halo so that you can be ready for anything. With our Variable Light Control Technology onboard you can adjust the light output with the control wheel to any point between the lowest low and the highest high so you can have highly personalized output and runtimes. With Coast’s commitment to quality, the HL27 Headlamp is impact resistant, weather resistant and its LED is virtually unbreakable. The HL27 Headlamp is backed by Coast’s lifetime warranty against defects in materials and workmanship. Tested and rated to ANSI/FL1 standards.
  • Pure beam focusing optic: ack two powerful beams into one and seamlessly transition - with no halos or hot spots- between short and long-range viewing; Coast’s patented focusing technology adapts to your need

Great Headlamp
Coast makes quality headlamps and this particular model HL27 is one of their brighter models with 309 lumens. It can be adjusted continuously from high to low light and also from flood to beam, both good features to have. You can also tilt the light up or down for different situations. I use it on my hardhat entering abandoned structures which makes it a plus for hands-free service with the included hardhat clips. It's a great bright light, but I think it's a little pricey. Other than the price, 5 stars

Great light, very even, robust and simple to use
I've had a number of other head torches, mostly from outdoor companies for camping and mountain biking. I've used plenty of those for handyman work too and so I'm comparing this with those NOT with handheld or area lights (the advantages/disadvantage of a head torch over those should be obvious). The only negative thing I can say about this head torch is that the battery pack doesn't sit precisely at the back of your head which just feels a bit lop-sided and takes some getting used to. Everything else, from the gorgeous Apple-like packaging, to robust quality of the unit, to the included helmet clips, to the amazingly clear and even light is top-notch. I hadn't even heard of this company before this product, and they're clearly a leader in this industry. I've included photos of a job I just did, replacing a light-switch with a dimmer switch, and obviously the head torch is excellent. I've also used this torch in a number of places you wouldn't think of, like when replacing a valve in my sprinkler system - even though it was daylight, just having the extra light when reaching into the sprinkler box/pit was a big advantage. Overall this compares very well with the more expensive outdoor-brand head-torches that I've used.

Brightens up any situation
I'm a definite fan of the Coast HL27 309 Lumen Focusing LED Headlamp. Powerful and lightweight, with a sturdy batter pack and adjustable brightness, focus, and angle, this headlamp offers all the usability and options I could possible want or need. It is very bright when set on the brightest setting. I haven't had the headlamp long enough to judge the battery life, but, if the instructions are accurate, the thing has a run time of 3h 45min on high light and 99h 30 min on the lowest setting (which is really unusable except in the absolute darkest situations). The headlamp comes in a super-sturdy box, and also comes with clips that allow you to attach the headlamp to a hardhat. I recommend this headlamp.

I LOVE this thing!!!!!
This headlamp is incredible. Its worth every penny. The build quality is top notch, and the LED and focusing technology that Coast uses is amazing. It allows you to focus it to a point (portraying a normal flashlight) or focus it to a very wide angle which disburses the light, but this thing is 300 lumens, so its bright enough at night to show you exactly what you want to see! This lamp also has a dimmer switch, which I dont use a whole lot, but it is very nice if you need to conserve battery, and it doesnt seem flimsy or loose, so I cant imagine any issues with a lot of use. The lamp also pivots forward to shine more toward the ground. Also the top strap is removable which might be more comfortable for some people. The battery pack is located in the back, and it runs off of 3 AA batteries (which were included with mine). My only complaint is that it is a little bit bulky which could get uncomfortable if you dont use it with a hardhat or anything. I use mine for overnight surf fishing trips to the gulf coast and it has performed flawlessly over 2 trips, and still running on the original batteries; I will gladly deal with the bulk because this headlamp is rugged and well built. The presentation and quality that Coast has put in the fine details is great! The packaging alone shows attention to detail. This is my second Coast product (I also have their LED flashlight) and I am more than impressed with both products. They've got my business for all of my future needs.

Fantastic product
Awesome headlamps and great customer service for warranty and fast shipping

Excellent features
I've had mine for 5 years. There are two features that make this headlamp above others, the adjustment of the beam, and the adjustment of the brightness. I love not clicking through modes but instead turning the brightness up and down as desired and adjusting the beam to flood or spot. It's awesome.
