How many lumens do you like? How many lumens do you need?

My lumen sweet spot for the "downcountry" trail riding I do at night is around 800 lumens as long as the beam pattern is wide enough and diffused well, across my whole field of view within the beam pattern. I sometimes will ride with only 500 lumens on a lower setting if I want to conserve battery power.

Would I like more than 800 lumens? Sure! Do i need it? ...no.

My advice to anyone choosing their first headlight is first and foremost...get what you want! But my advice to anyone that is choosing their first headlight based on lumens is.....don't feel like you need as high lumen output as many expensive headlights offer.

This is all subjective and everyones preferences are naturally different, and the trails we all ride can be very different, along with our skills and speeds we like to ride. Me for instance, I don't bomb down hills and I avoid jumps and drops because I'm older than most riders and avoid injuries to myself and my bike, so less than 1000 lumens works for me.

Also my advice for what it's worth...I would say, that if all headlights were no brighter than 1000 lumens, we'd all be okay with that and we would be able to ride at night on most trails at night at varying speeds. So when choosing a headlight, be sure to look closely at the low, medium, and high lumen output settings on the headlight, and how many runtime hours it offers on each setting. Ask yourself how many hours you want to ride at night....2 hours? 5 hours?

For me it's more important to focus on how many hours the headlight will run at whatever setting is close to 800 lumens for a minimum of 2.5-3 hours. For me to get a headlight that offers at least 3 hours of runtime around 800-1000 lumens, I have to shop for a headlight that usually has at least a 5200mah battery, and a battery that size in a self-contained headlight will usually offer a much higher lumen output than 800-1000 lumens on it's highest setting. So what I look at closer than it's highest lumen output, is how long the headlight runs at it's medium setting typically. What gets tricky is that each make and model of headlight has a big difference in lumen output between it's own low, medium, and high settings, and if I'm looking for a new headlight with the right balance of lumens vs battery runtime, I often have to comprimise between slightly lower lumens with extra runtime, or higher lumens than I need with a shorter runtime than I'd like. Another tricky thing is the beam pattern and efficiency between makes and models. One model might offer 1200 lumens but appear to be less bright than another model's 800 lumen setting. The beam patterns width will vary. Some models flood better than others, while some models may be more like a spotlight.

What would be great is if there was a headlight that allows you to choose your own specific lumen output and not have to choose between factory settings. For instance If there was a headlight with a 10000mah battery and you could dial in your lumen output to anywhere between 100 and 3000 lumens, with several different beam pattern setting, or interchangeable filters/diffusers....that would probably be a pretty popular headlight!

Different for everyone.

I see better than average in low light and darkness. ~600-ish helmet mounted lumens works for me and don't really need wide beam.

Lights of 5+ years ago tended to be whiter... newer ones are a bit different/warmer which I don't like.

Other riders in my past crew went brighter with multiple lights. Tended to cast a lot of shadows for riders in front of them.

To think we used to ride with about 15 watts of xenon bulbs....

Our trails are pretty narrow and twisty, so I can ride pretty easily with about 250 lumens x 2 until I get to someplace more open.
I think I have a NR 750 narrow and an NR 1000 wide. They last many hours on the lowest setting, and I seldom use the highest setting. In the snow, I can almost ride by candlelight.

Min 2000 lumin on the bar and the same on the head.

im actually running 4500 lumin on the head and 2000 on the bar. Both flood beam. I dont run spot anymore.

PS my riding doesnt change day/night. I'm still hitting the same rediculous double black stuff at night too. So.... lights need to be day bringers.

I am of similar opinion these days, running floody 4500 lumen lights on both my helmet and bars.

Can I get away with less? Absolutely, and sometimes I do. But, I have found the argument that a well-patterned 1000 lumen light is just as good as a higher powered light to be bogus for ME.

My Outbound Hangover light is nice, but only gets use for the all-in-one convenience aspect. It does not favorably compare to my Magicshine MJ906S for the kind of riding I normally do (techy singletrack at daylight speeds).

Oh yeah, I went to the optometrist this past year for the first time in ages. I, unfortunately, have early onset cataracts. WTH? I guess that might explain why I hate driving at night nowadays.

For commuting, the more the better, 5000+. If I could have just laser beams (for commuting) I would.

For trail riding, the faster you go, the more you need. If I'm dropping a DH trail, I want it turned up a bunch. 500 in the snow is ok for most riding, but when I start going faster, I want closer to 1000 coming out of my bars and helmet as a starting point. With bigger jumps, more light. Remotes for lights are super nice, like dropper posts. Then you can turn the light up when you need, turn it down when you don't. Extend battery life, increase control.

Is also worth noting that pencil beams though the give you are intense focused bit of light become a bouncing bloody light disco show when you ride some ready bumpy terrain.
If you have 2 penciles, one on the bar and one on the helmet they bounce opposite to each other and make for a real good seisure setting.
Flood beam needs more power, however dual flood beams merge into one and even if your helmet and bar are bouncing all over the place all you can see is a big blob of light. No more seisure setting.

Unless you want to spot light and shoot animals at night throw any pencil light into the bin and get a flood equivalent.

Think I might have found one for you. Moon Rigel Max 3600. It has 4 spot and 2 flood emitters and can be run SS, SSFF, or SSSSFF. Not sure about the battery capacity but @ 750L with all the emitters activated it shows a 6 hr runtime. It also has a VLS mode that is basically a ramping mode so you can adjust the output to whatever you like (within the range of the light).

Not sure if any bike specific lights use Anduril for an OS...but it has something called "smooth or gradual tint ramping". It gives a smooth transition between brightness settings and it has more settings than the typical three to four on your traditional bike lights.

My bar lights have a max of 2k lumens and my helmet light has a max of 500. For me...that combo is more than enough for pitch black areas. I only have it on high when I'm descending. If I'm climbing or just cruising along...both lights are on the low or mid settings. Having a light on my helmet lets me use a lower setting on my bar light.

I roll with an Outbound Lighting (highly recommended) Trail Evo on my bars, and a NiteRider 1100 OLED on my helmet. Plenty of light for rough terrain, especially on high settings, but I don't know the lumen count of the Evo.

I have ridden with a guy who has an "enduro" light (not sure brand, might be a seca) that we affectionately call "the sun" due to its epic brightness. I'd guess it's 3000+ lumens. As long as you're not riding the opposite direction it's great.

I still remember when the OG magicshine hit the market. They were incredible compared to the old lights. I got my original magicshine out the other day and compared it to my much newer light and there's no comparison. This technology has absolutely exploded the past 15 -20 years.

I had the Nightsun halogen lights with the 200 pound lead acid battery back in the early 90's.

Now, Niterider race 1500. On the helmet, either a Niterider Lumina 850 or 1200. The 1500 lumens setting only good for an hour and a half, but only use that on descents. The middle setting (900 lumens) supposedly good for 3 hours. The low (450) is fine for slow sections, climbing.
I generally don't do 3 hour night rides. The Race 1500 has been a solid system for me for about 10yrs now.

If I'm doing a ride that transitions into a night ride, will bring the 1200 on the bars for the last bit of the ride to get home.

Thats a nice question! I tried once the 8.000 lumens magicshine. I didnt like it. Your eyes cope up with the brightness of your light (pupils are quite close) and if you wanna see peripherically outside of your light field you cant see anything! With a mild light peripherical view is way better(pupils wide open). For commuting i guess you need to bypass other vehicle lights, so you actually need a stronger light.

Light and Motion Seca 2200 Enduro is around 2k likens and a nice flood pattern. Perfect on the helmet and even going fast and through jumps I don’t need anything else. Awesome light and I’ve had it a year and a half with zero upgrade itis.
The Niterider 2000 lumen I also have sucks in comparison. Spot beam and the battery stopped taking a charge 6 months in. It was my loaner but now I’m not going to bother buying a new battery.
