I like the Bontrager ones. I think they have a few options for USB rechargeable

Axiom Pulse 60 - recommended on a recent thread. I'm happy with it, bright, keeps a charge, easy mount and cheap. On sale for $30 here:

ETA - I'm wearing it running now too as the clip secures it easily to a very light reflective vest and it doesn't bounce. Easy to switch back and forth

 
Cygolite Hotshot is a great option and what I am currently using. It is bright enough to induce a seizure and has multiple flash patterns and speeds. Good price and good battery life as well.

On the topic of Cygolite, I think that the Dart 350 would really fit the bill for a small front light.

+1 on the Cygolite Hotshot, though I like this Serfas better: https://www.bikelightdatabase.com/...hunderbolttaillight/. I own both, and it is a bit more flexible in where you can mount it compared to the Hotshot, though it has less flashing pattern options. The Cygolite you can really go crazy with all of the options, but I found I didn't really see the need. The Serfas is basically on low, on high, and blink high, which is really all you need. I have had many comments on its brightness and visibility, even in full sun.


(The site linked above site is a great resource for researching lights, btw).

I use the Light & Motion 650. Really bright, has 3-4 settings. I believe they also have lower lumen versions.

Thanks for all the responses. Cygolite hotshot seems like a great deal, I think I might get a little more spendy though after doing some more research. I've got some amazon gift credit to burn and leaning towards Light and Motion Urban 800 / Vis 180 combo. I like that the front light can use my combo garmin / gopro mount on my road bike and I can swap the rear easily with an extra mount to some of my other bikes.

The Light and Motion Urban also attaches to aeobars super easy and I use one on all my road TT riding.

Any suggestions for a super bright main light for full on night time riding/commuting? Something that lasts for about 60-90 minutes?

I really like my Cateye Volt 700. (In fact I have 2). They now have the 800 which is the same size.

I highly recommend the Cygolite Expilion 800 (I think it's the 850 now).
Last 90 minutes on high, even longer on the medium setting, also has a great daytime blink mode.
And has interchangeable batteries, so if you stick a spare in your pocket you will never run out of light.
I use it both on my MTB and road bike and I think it's great.

x2 on the Bontrager rear red light....CRAZY bright! They make a nice front light too, and I have a Nightrider that I'm quite happy with. Another option I was looking at is the Garmin Varia, as it is the radar unit, but I'm not sure if that's bright, or just a good notification of cars coming from behind.

I have the Cygolite hotshot. It's legit - very bright, super visible in dark/dusk, and lasts long.

That said, I gave my old 6-year old Planet bike blinky (these are very well regarded/reviewed) to a friend who started riding, and even though it's less powerful than the Cygolite, it was still very bright and noticeable - I even had to ask him if that was the same blinky I gave him, since I was so impressed!

I have the Light and Motion Urban 800 / Vis 180 combo. Very well engineered, works well, battery life isn't fantastic but adequate. The flash option for the Urban is a pulse, which I believe is consistent with European regulations, on the upside it's less blinding for those you may encounter, on the downside also less visible, especially during the day.

Cateye Volt 800 / Bontrager Flare RT combo here.

Really digging the ANT+ combo with my edge 820.

The new versions of the Light and Motion Urban have no "flash" mode, which in my view disqualifies them. I have two of them, and the one without flash mode gets almost zero use. They're still good as a headlight for pure night riding, but in low light, dusk, or daytime or city or commute use I think it's important to have a flash mode. (Actually at night I typically use two lights, one on steady and one in flash mode -- the one in flash mode serves to make sure I'm seen and also serves as a backup in case of a battery failure, so I can still get home, so even at night I think it's important to have one flashing light.)

The cateye volt 1600 lumens is really nice. It is self contained and a true 1600 lumens. You can get a full 2 hours on 1600 lumens, and it also offers a fantastic daylight flash option that is great for sunrise, daytime, and dusk. I picked one up recently on sale on amazon for $159.

A bit more pricey, but the Fly6 and Fly12 are good safer options if you want to couple with video evidence.

I was buying new lights every fall until I sprung for an Exposure Diablo. Not cheap, but a great mix of pure power, good battery life, and just a quality build/mount.

The Lyzene lights are great for commuting. Good battery life, solid casings that can take a beating and keep on chugging.

At night, ditch blinkers and go with solid mode. What you want is for people to be able to make out exactly what you are. That's why lots of little lights are good but it's easier for the drivers to understand what they are seeing if the lights are solid. Blinking lights alert drivers but confuse them. They can't make out the geometry of what they're seeing.

And in that regard, these are fantastic:

The driver comes behind you and sees these bright lights on your shoes going up and down and instantly their brain fills in the gaps and understands it's a cyclist.

++ Bontrager Flare R Rechargeable I rode 6 hours last weekend it never failed, 2 Miles visibility best on the market! It's more about the concentration of the light beam then the strength of the light.
