Fenix vs Black Diamond: Which Headlamp Should You Buy?

Buy the Fenix HM61R V3.0 if the hunter walks a long way in the dark. Its 18650 cell comes out, so a spare in a pocket turns a dead headlamp into a ten-second problem instead of the end of the hunt. Buy the Black Diamond Spot 400-R instead if the lamp mostly gets used within sight of the truck — it is lighter on the head, it costs substantially less, and its battery meter reports remaining runtime rather than just blinking at you when it is nearly over.

These two brands get compared constantly and almost never on the thing that separates them. Search results will hand you lumen counts: 1,800 for the Fenix against 400 for the Black Diamond, which reads like a knockout and is close to meaningless. A hunter spends almost the entire night in the dimmest mode that works, because a bright beam wrecks your own dark adaptation and carries a long way across open country. Nobody walks to a stand on 1,800 lumens.

What actually separates them is battery philosophy. Fenix built an industrial lamp around a cell you can replace. Black Diamond built an outdoor lamp around a cell you cannot, and then spent the engineering budget on telling you how much of it is left. Both are defensible. Only one of them is right for a particular hunter, and this page is about working out which.

Every figure here is the manufacturer's or a retailer's published specification, cited at the bottom. We have not measured a lumen or timed a battery, and where published sources disagree — and on the Black Diamond's waterproof rating they do — this page says so rather than picking the flattering number.

Two cells in that table say what they say for a reason. Black Diamond's waterproof rating is listed differently by different retailers, and we are not going to resolve that disagreement by picking one. The Spot 400-R's weight is not published anywhere we could verify to the same standard as the Fenix figure, so the row says so instead of estimating a number that would then get quoted back at us.

Rechargeable headlamps fixed a real problem. Nobody misses hunting for AAA cells in a kitchen drawer at four in the morning, nobody misses corroded contacts, and a lithium cell holds its voltage in cold far better than the alkalines most headlamps ship with. All of that is genuine, and it is why both lamps here are rechargeable.

It bought those things by sealing the battery inside the lamp, and that created a failure that a disposable-battery headlamp does not have. A lamp with spare AAAs in your pocket that dies on the walk out is thirty seconds of annoyance. A sealed rechargeable lamp that dies on the walk out is over, and you finish the night by phone light with one hand occupied.

There are exactly two good answers to that, and these two lamps are each one of them.

Fenix answers it by making the failure recoverable. The 18650 comes out. Buy one spare, keep it in the bino harness or a pack pocket, and the worst case costs you the time it takes to unscrew a tailcap. This is the cheapest redundancy available to a hunter, and it is why the Fenix tops our best rechargeable headlamp for hunting roundup too.

Black Diamond answers it by making the failure predictable. You cannot swap the cell, so instead the lamp tells you how much runtime is left before you commit to the walk. A meter that reports remaining hours rather than blinking a low-battery warning at the very end converts a surprise into a decision you make at the truck, where the charger is.

The 1,800-against-400 gap is the first thing anyone notices and close to the last thing that should decide this. Headlamp output is sold the way horsepower is sold, and hunting uses it the way a tractor uses horsepower: almost never at the top.

Three reasons the big number does not earn its keep in the woods. Your own dark adaptation takes twenty to thirty minutes to build and a couple of seconds of white light to destroy, so the hunter who runs a bright beam on the walk in arrives unable to see anything the lamp is not pointed at. Bright light also travels — in open country a hunter on high beam is visible from a very long way off, to game and to anyone else hunting that block. And runtime collapses at the top setting on every lamp ever made: the Black Diamond's own published figures go from about 4 hours on high to around 225 on low.

What actually matters is the bottom of the range and how finely you can get there. The Fenix publishes a 5 lumen flood and a 3 lumen red; the Black Diamond publishes 6 lumens on low with a dimmable red. Those are the modes a hunter lives in, and they are nearly identical. If you want this argument in full, with the arithmetic, how many lumens for a hunting headlamp works through it.

Neither of these lamps has a green mode, which is worth knowing before you buy either for a hunter who needs one.

Redis for protecting your own night vision. It barely disturbs dark adaptation, so you can check a pack, tie a boot or find a release and still see by starlight half a minute later. It also carries less far than white, which announces you less on the walk in. Both lamps here do red, and the Fenix does it at three fixed levels where the Black Diamond does it dimmable — a real preference split rather than a better-and-worse.

Green is for telling colors apart in the dark, which in practice means following a blood trail, and it is the color predator and hog hunters favor for moving game at night. If that is the hunting, neither lamp on this page is the right answer and the budget pick above or a green-first lamp is. Red or green light for hunting covers the trade properly.

A headlamp is a quietly excellent hunting gift. Every hunter uses one, hardly any of them own a good one, and there is no size, fit or taste to get wrong. The only real risk is that it does not feel like a present — which is an argument for the nicer lamp rather than the sensible one.

If you are buying for somebody else, three practical notes. First, the Black Diamond is the better-looking gift of these two: it is a recognizable outdoor brand in retail packaging, where the Fenix arrives looking like something ordered for a job site. Second, if you buy the Fenix, buy the spare 18650 with it and wrap both — the spare is the entire point of that lamp and a recipient who does not know that will never buy one. Third, and this is the quietly best move: buy the cheap EverBrite alongside whichever you choose. Two lights is the rule experienced hunters follow, almost nobody buys the second one for themselves, and it costs very little to complete the gift properly.

For the whole category rather than this pair, the best rechargeable headlamp for hunting ranks five lamps on the same battery question, and best hunting headlamps includes the disposable-battery lamps this page leaves out. If a headlamp is not quite the present you had in mind, hunting stocking stuffers and best hunting gadgets and tools are the neighboring lists. And if the hunter you are buying for is cold rather than in the dark, the best heated hunting vest solves a bigger problem than any light does.

We did not test these lamps against each other. No one on our side has run both batteries flat or dunked either one. What this page does instead is take each manufacturer's published specifications and the retailer listings that carry the numbers the manufacturers leave out, note the places those sources disagree, and reason from the single design decision — removable cell against sealed cell with a meter — that explains the weight, the price and the field behavior of both lamps better than any spec row does. Every published figure is cited below. Where a figure was not published anywhere we could verify, this page says so instead of estimating. Our method is on the how we choose page, and prices come live from Amazon with the date they were captured.
