Black Diamond Revolt Headlamp

I won't repeat Voiceover Guy's review which covers all the bases well, I'll just add some more details and thoughts.I agree this is a great light with useful features and good implementation. I personally like the USB recharging because it means I can recharge the light with a 5V solar panel when out in the wild. And you can charge at the start of your trip instead of tossing probably half full alkalines to put in fresh ones every time you go on a trip.As to replacement rechargeables read reviews on the older versions of the Revolt for specific guidance. In order to protect consumers from themselves BD uses slightly different battery terminals on their rechargeables to prevent the light from attempting to charge non-rechargeable batteries. You can use generic rechargeables (i.e. don't have to buy from BD) if you just modify the tops of the batteries a little.Be aware in the spot mode that the central region of the spot has an odd yellow color to it. This seems to be true of all the similarly designed BD headlamps. I haven't used the light enough for this to annoy me yet, but the color non-uniformity is definitely there and according to BD is a limitation of the higher power nature of the LED used. I suspect for hiking uses it is a non issue, but if using the dimmed spot mode to look at things like maps or books this could be annoying. For me a week of typical use on a trip and I really didn't notice the yellow spot unless I went out of my way to look for it, but on a uniform white page it is more easily noticeable.Also check the battery life for flood mode. This is not particularly efficient in run time in flood mode. This is to be expected to a degree - the flood mode is very much a FLOOD mode. The beam width is extremely wide. The spot mode has a lens that focuses the light to a much tighter beam and is thus more efficient. One benefit of the very wide flood mode is it seems like this would work great as a top of the tent lantern. Also provides uniform illumination when looking at close objects like reading a book. So, great wide uniform flood mode but just be aware the flood mode uses up a lot more battery life than the spot for a given illumination level.The red mode is not nearly as nice as the white modes. First be aware that it is a spot, not a flood. The beam width is quite narrow. Second be aware that the beam pattern and uniformity is quite poor. You essentially get bright rings at the periphery of the beam and a dimmer center. As noted in other reviews it has a very useful feature in which you don't have to cycle through white to get into the red mode. And once in the red mode you also can't accidentally end up in white mode unless you hold down the button for three seconds. This makes the red mode much more useful than on many lights where you are forced to blind yourself or those around you cycling through white to get to red. All in all using the red mode in a dark environment for a number of nights I found it very useful and the non-uniform beam pattern was not an issue in practical use.Now to my one disappointment, which is probably nitpicking and not going to be an issue for the vast majority of users. You can not dim the red light mode, despite the fact that the manual is written implying you can (See UPDATES at end of review with regard to this issue, it appears current versions do now dim red mode). I went back and forth with Black Diamond customer service on this and after some checking on their end they determined that manual is not correct and the Revolt does not dim on red mode. Note that the Spot and Storm head lamps do have a dimming red mode so if this is important to you then give those lamps a look.In practical use the red is about as dim as you would want already for walking and distant work. And most people probably want it at the brightness it is for close work. But for some niche applications like looking at star charts or detailed maps when working with fully dark adapted eyes the one setting for red is a bit too bright when viewing close up charts and maps.Otherwise dimming in the white mode is quite good because it does dim down to quite low light levels. Many other dimming lights don't seem to get very dim. If you are trying to work in moonlight and maintain some dark adaption having really dim settings is very useful. I found that for distant work like walking with the dimmed spot mode or scanning an area for items left behind with the dimmed flood mode that the minimum white brightness was a good level to see clearly without compromising dark adapted eyes too much.I've discovered one great feature of the dimming mode as well. It blinks the light at the dimmest setting. With dark adapted eyes this means you can reliably set to dimmest level without having to directly view the bright level. With your eyes closed you can still perceive when the light blinks at its dimmest setting. So, close your eyes and turn on light (comes on at 75%) then hold down button with eyes still closed and it will go to 100% and then slowly dim. At the dimmest it will pause and blink and even with my eyes closed in a dark environment I can perceive the blink and release the button. Then open my eyes to a nice dim light without ever having viewed to bright setting. As for anyone around you, well too bad for them unless they close their eyes while you adjust your lamp.Also there is the question of price. These things are quite expensive compared to a more basic three battery head lamp. It is a very feature rich lamp, but if you just want basic light there are less expensive options. Fortunately they go on sale pretty frequently. I feel that the collection of features, especially the recharging and dimming, it is definitely worth the on sale prices. At something like two Andrew Jackson's or so this is a great feature set for the price. But honestly, if you want all these features and the excellent recharging feature then this is the light for you and most any price.If you don't need the recharging feature then get the BD Spot instead. Same feature set (and red dimming actually works to boot) but for a lower price. The Spot also has a cute feature where tapping the light sets it to full brightness and tapping again sets it back to your dimmed level. The Revolt doesn't have this feature and instead has the USB charging port where the tap sensor is in the Spot.UPDATE 12/11/14 - I've edited the review to reflect information from Black Diamond customer support regarding the manual for the Revolt incorrectly indicating that dimming works in the red mode. It does not in fact dim in red mode. BD customer support was extremely helpful in sorting that out for me and went out of their way to make sure I ended up with a BD light I was happy with. Seems like a great company making excellent products.UPDATE 4/7/16 - Another reviewer has commented that the light they've just received does now successfully dim the red mode. It appears BD has updated the firmware along the way at some point to support red dimming like most of their other models.

A very nice headlamp. A lot of candle power that was more than bright enough for what I would be using this for. It is adjustable brightness that also includes red LED's for night vision.It comes with rechargeable batteries that seem to hold a long time charge at full brightness which so far leads me to believe they are high quality. As per instructions I charged up the batteries overnight and let it drain completely down before putting another full charge on them.I had strong light for a number of hours, 6-8, which gradually decreased in brightness. It took over 24 hours to completely drain the batteries on full brightness at which I was amazed. Again, take into account that the light was very weak after about 20 hours of run time.The headband was very comfortable and is adjustable for fit. It comes with a great light meter to give you the amount of charge left on the batteries.The only con I can think of is that it comes with a USB charger to hook into a computer or whatever to charge. This is a very nice option but it was a slow process as it took overnight to fully charge the batteries. I wish it included a wall socket adapter to recharge these as I don't usually leave my computer on overnight.Final Note: It was a bit costly but I would buy it again.

This LED Headlamp is very nice and one of the top name brand headlamps. I purchased this Black Diamond, the Coast HL7R, and a couple of low budget lights, the Vitchelo V800 and the Foxelli 165 lumen model for various needs. These were from $20 to over $50 for this Black Diamond. The Black Diamond ReVolt is the winner on rechargeable long battery life with best charging circuit control and good adjustability. Main minor negatives are that it could be brighter and half or even 1/4 the battery life and be better a better compromise for me, and that it has a modest IPX4 at best waterproof rating. Looking at the battery compartment, a stream of water or hard downpour would get the innards moist/wet, and not sure if that would compromise the LED/charge electronics, but not good to have water get in.Pros: Great compromise of light weight, good usable mid flood beam light, infinite power level adjustment, exceptional battery life with 12+ hours on high, best in class charging circuit and solid quality. Decent secondary white and red LEDs.Cons: Not super bright, kind of heavy on front of head, and bounces around if not tight head band, which gave pressure on my head worse than others, lack of beam focusing or type. Secondary white LEDs don't add much value due to huge battery life anyway and relatively wide beam of primary LED.See my reviews of the other headlamps listed.

This is a great headlamp, its very bright and has many great options. I love the 'floodlight' mode on it, its perfect for reading, while the main beam mode is a great spotlight. The red function is perfect for preserving your night vision as well. The dimming function is really smooth as the light will dim down and you choose the exact brightness you want it at. There is also a strobe function, but I almost never have a use for it. It came with a rechargeable battery, and you can plug it in to recharge it, but I haven't tried using that yet as my first 7 weeks of using it were without any power source to plug into.

Portable, rechargeable and a powerful light source!

this is a very practical headlamp. the usb recharge possibility is very nice as is the fact that you can also use normal AAA batteries. One small detail is that the rechargeable batteries must come from Black Diamond company (otherwise the headlamp won't charge them). The headlamp is packed full of features (dim light, night reading, lock lamp, flash mode). Not the most impressive lamp in terms of luminosity but a very good all around tool and well built

Après avoir regard les caractéristiques de ce Produit sur des cites spécialisés de sport, je confirme que c est vraiment une très bonne lampe ,voir une des meilleur dans le domaine de multiples activités sportives. En tout cas c est la seule que j ai trouvé qui est faite pour le vtt . eclairage multiples ,vision large et lointaine , parfaite pour le vtt ,marche ext... Le petit plus, c est que vous pouvez installer 3 piles rechargeable (fournies avec cable usb /micro usb ) et ainsi vous n'etes jamais a court d'énergie. Vraiment un superbe produit.

Sitz Super auf dem Kopf, verrutscht nicht und leuchte hell. Handhabung sehr einfach und gut durchdacht. Klare Kaufempfelung fur diese Produkt.

La qualità del prodotto è molto elevata ed il fascio luminoso è sorprendentemente potente considerando le dimensioni ed il peso.Ottima anche la durata: è veramente un'impresa scaricare le batterie ricaricabili a corredo per poterle ricaricare comodamente tramite cavo USB.Secondo me sono ottime abbinate ad un caschetto Black Diamond ("Half Dome" oppure il meraviglioso "Vector").
