The best light for urban running, when it's more about being seen than othersseeing, is the Black Diamond Sprinter. It's small, rechargeable, bright, balanced, with an even light, and has a rear flashing red LED built in. Below However, the light I use most is the Light Belt, a summary waist mounted light that allows you to see the shape of the ground ahead, and I prefer it even on asphalt. And while I almost never use the Petzl e+lite, it's my recommendations, followed by faithful "oops" light I carry as a look at backup. =Light Belt=I love waist mounted lights as you can see the shape of the key factors ground so much better. This style of light is relatively rare, and I've been pleased to look work with Light Belt as they've developed and refined their product. I found this is the light I've used consistently, even for in running on the relatively smooth asphalt of my local Greenway. If you've not run with a waist mounted light, I'd suggest playing around with your head mounted light , taking it off and moving it to your waist and then a look at each light in turnseeing how your perception of the ground ahead of you changes. {| class="wikitable"!Light!!Why Once you've made to the switch, it's recommended!!Cost|-|[hard to go back.

There are four factors to consider with a running light; location, the beam pattern, regulation and brightness.
==Location==
The three locations for first step in choosing a light while running are handheld, waist mounted and head mounted. I do not recommend handheld lights for several reasons. The biggest problem is that keeping to work out where you want the light pointed ; in the right direction changes your arm movement and messes up hand, at your waist, or on your running formhead. In addition===Head Mounted===Most people use head mounted lights, handheld lights occupy one and they have a number of advantages:* Head mounted directs the light where you point your hands head, making it tricky easier to see where you're going. * Head mounted also works better for directing the light to do anything things in the darkyour hands, though like putting on gloves or looking at your [[http://wwwBest Running Watch| Running Watch]].knucklelights* Head mounted lights are better at showing up branches or spider webs that are about to hit your face.com/ knuckle * Most of the lights] overcome thisare head mounted, so you have the widest choice. There ===Waist Mounted===Waist mounted lights are advantages much better at showing you the shape of the ground, and disadvantages to waist mounted and head mountedany obstacles are a lot more apparent. Because This is because a head mounted light is aligned with your eyes, itso there's hard to see the shape few shadows. Below are sets of photos taken with the ground[https://apps.apple. This is best seen in the images belowcom/us/app/stabilized-night-camera/id1433896496| Stabilized Night Camera app] that allows for long exposure. <gallery widths=500px 300px heights=400px300px class="center" perrow="2">File:RXP Eye LevelComparing waist and head mounted lights (1).jpg|The light at eye levelJPGFile:Comparing waist and head mounted lights (3).JPGFile:Comparing waist and head mounted lights (4).JPGFile:Comparing waist and head mounted lights (5).JPGFile:Comparing waist and head mounted lights (6).JPGFile:Comparing waist and head mounted lights (7).JPGFile:Comparing waist and head mounted lights (8).JPGFile:Comparing waist and head mounted lights (9).JPGFile:Comparing waist and head mounted lights (10).JPGFile: Notice how 'flat' the path looksComparing waist and head mounted lights (11).JPGFile:RXP Waist LevelComparing waist and head mounted lights (12).jpg|The light at JPGFile:Comparing waist level shows the texture and shape of the pathhead mounted lights (13).

Other considerations:* Head mounted directs the light where you point your headIn rain or dusty conditions, making it easier to see where you're going. Head a waist mounted also works better for directing the light to things will not create glare in front of your hands, like putting on gloves or looking at your [[Best Running Watch|Watch]]. * Waist mounted lights are much better in the rain or dusty conditionsface. With a head mounted light, the beam picks up the rain or dust in front , and because of your face, making it the closeness these particles are brightly lit. It can be hard to see. * Head mounted lights are better at showing up branches or spider webs that are about to hit your face. ==Beam Pattern==Most lights project a narrow spot beamthrough these spots, which illuminates a longer distance. Many of and the Petzl lights have a diffuser than effect can be moved quite claustrophobic. It doesn't capture the full difference in front visibility, but it gives you a sense of how much easier it is to see in the rain with a waist mounted light to provide an even illumination, though it does not reach so far. <gallery widths=500px 300px heights=400px caption="Head or waist mounted lights"300px>File:RXP SpotHeadlight in the rain.jpg|The spot beam illuminates furtherHeadlight in the rainFile:RXP Eye LevelWaistlight in the rain.jpg|The diffuse beam illuminates wider and more evenlyWaist mounted light in the rain
</gallery>
If there are insects about, a head mounted light causes them to fly into your face, which is even more unpleasant. ===Handheld===I don't recommend handheld lights for several reasons. The biggest problem is that keeping the light pointed in the right direction changes your arm movement and this messes up your [[Running Form]]. In addition, handheld lights occupy one of your hands making it tricky to do anything in the dark, though knuckle lights overcome this. ==Beam Pattern – Spot vs Diffuse=={| class="wikitable"|- valign="top"|[[File:RXP Spot.jpg |none|thumb|350px| The spot beam illuminates further.]]|[[File:RXP Eye Level.jpg |none|thumb|350px| The diffuse beam illuminates wider and more evenly.]]|}Many lights project a narrow spot beam that illuminates longer distance, which can be handy for navigation, especially on ill-defined trails. Most of the time I prefer a light with an evenly diffused beam, even though it does not reach as far as a spot beam. ==Regulation– Light output over time==With a regulated light the light intensity will stay constant over most of the life of the battery. When the battery is nearly depleted, and it the light will then grow rapidly dim. This can be seen graphically (see the graph below. ) The regulation is nice, but when the end of the regulation period is reached, the light intensity can drop very so quickly, so you need to have spare batteries with that you if you expect to run get caught out of power. [[File:Light Regulation.jpg|none|thumb|250px350px|The difference between regulated and unregulated light output.]]
==Brightness==
The brightness you need depends on your situation. In many cases you just need to see what's immediately ahead of you, so brightness is not critical. If you're on trails, then a really bright light can help see what direction a trail is taking, or help with navigation. Many times I've found that having a dim A bright light can work bestalso help psychologically, as it helps me see what's ahead without compromising my night vision, allowing me overall better visibility. A very bright light will create a small pool of light that can become mentally confining and isolatingclaustrophobic. Having a light that will go both very bright and very dim is ideal, and the [http://go.fellrnr.com/?id=35454X937677&xs=1&xcust=LightRXP&url=http%3A%2F%2Fwww.amazon.com%2FPetzl-E87-P2-Myo-Headlamp%2Fdp%2FB004OYTOA0 Petzl MYO RXP] stands out for this. =Recommended Lights=I have tried over a dozen different lights, from the bad old days of incandescent lights that give a patchy yellow glow to new regulated LED lights. My two favorite lights are both Petzl as they have an effective diffuser. I've also tried lights from other manufacturersHowever, but I've consistently found Petzl lights to be better. ==Highly Recommended - Petzl MYO RXP==The [http://go.fellrnr.com/?id=35454X937677&xs=1&xcust=LightRXP&url=http%3A%2F%2Fwww.amazon.com%2FPetzl-E87-P2-Myo-Headlamp%2Fdp%2FB004OYTOA0 Petzl MYO RXP] is a regulated light, as described above. The light will flash a few times when the battery drops too low, which gives you some warning before it runs out of power. The RXP also support brighter output that is unregulated, which is useful when you need a lot of light for a short period of time. The regulated output can be used so that you will have power for an overnight run, and on its lowest power setting it will run for 96 hours. The RXP is also nice because it can output a very dim light. I've found this works well near dawn, where the light from the RXP on its lowest output and with the diffuser is enough to see by, but allows my eyes to adjust so that I can see a little further using the available light. I've found the RXP works well in heavy rain as long as it is in the normal position. If you run with it wrapped around your hand, the rain can get in the underside and cause problems until it dries out. The RXP uses AA batteries, so it is a little heavy, but having the batteries on the back balances things quite well. It also allows the batteries to stay warmer in cold conditions if you wear it with the back under a hat; youthere'll probably need two hats to make that work. <gallery widths=400px heights=300px caption="Petzl MYO RXP" perrow="2">File:Petzl MYO XP Full.jpg|Full view of the RXP. Note the battery pack on the rear of the strap.File:Petzl MYO XP Close.jpg|A closer view, showing the diffuser over the light. The diffuser flips down for a spot beam. There are two controls; the level button and the high power button. </gallery>===MYO RXP Battery Life===The battery life chart shown below can be s a little confusing. The blue area shows the settings when the more ambient light is regulated, which keeps the lighting level constant until the battery level drop too low and then the brightness plummets. Here are some examples from the chart to help explain things.* On setting #1, the light will give out a steady (regulated) 8 lumens for 35 hour. The total battery life is 95 hours, but from 35 hours to 95 hours it will be very dim.* On setting #8, the light will give out a steady (regulated) 71 lumens, but only for one hour. The total battery life is 54 hours, but after the first hour the light will grow rapidly dimmer.* On setting #10, the light will start giving out 140 lumens, but it will immediately start to grow gradually dimmer. This drop in light level will be gradual enough that it will not be immediately detectable.* The actual battery life will depend on the batteries used and the temperature. The chart is for fresh alkaline batteries at 68f/20c, and cold weather can reduce the battery life quite a bit. Lithium batteries will last longer and rechargeable batteries will last for less time. * The claimed battery life matches up with my experiences. I use the [http://go.fellrnr.com?id=35454X937677&xs=1&xcust=enloop&url=http%3A%2F%2Fwww.amazon.com%2FSanyo-eneloop-Pre-Charged-Rechargeable-Batteries%2Fdp%2FB004SB1TD4 Enloop Low Self Discharge rechargeable batteries], so I get slightly less runtime than indicated, but it's close.

This works work best with compression shorts/tights to prevent the light wobbling around. I've found this works far better on trails than a head mounted light. The XP Adapt uses AAA batteries, so it's lighter than the Petzl MYO RXP.

There are two bulbs, one with a diffuse wide beam and the other with a narrow focused beam, along with a light sensor. When the light is pointing slightly down, the wide beam is used, and when you look up, the focused beam comes on as well. When you look at something close up, the wide beam comes on at a dimmer level. This works quite nicely when running, as it uses the wide beam when you're looking near your feet, and a longer throw when you look up to see further ahead. If you look at your watch (or anything else close up) it uses a dimmer light. You can also program the light using a computer (PC or Mac) provide enough to set the intensity of the three beams (wide beam, narrow beam and wide beam close up). However, the close up mode is also activated if a light is shining at shoe you, making it a poor choice for running near oncoming cars. You can change to a constant mode, but that defeats the purpose of the light somewhat. The Nao comes with a rechargeable battery, but can also take 2 AAA batteries and you can buy [http://go.fellrnr.com/?id=35454X937677&xs=1&xcust=NaoB&url=http%3A%2F%2Fwww.amazon.com%2FAccu-Rechargeable-Battery-YYYY-Petzl%2Fdp%2FB007K03LCC spare batteries] for about $60. The battery life varies on usage, so if you're doing a longer run, you'd want to carry spare batteries. The rechargeable batteries probably make this unsuitable for many overnight ultras.
