Best flashlight to use as a bicycle headlight? Stock not modded. Preferably 18650 or 21700.

cu42 i have the Q8 and i agree with what you said. But yes the fat body is kinda am issue to me for now.

I just bought an Indigo 5 light. It’s a 26650, but specifically designed for cycling with a 3000k 90cri mtg2 emiter for a large hotspot and large spill. Build quality is impecable.

Currently on sale too!

My apologies cu42. I confused myself a little bit about your post of the Q8 on medium.

What do you use to mount your Klaus G20?

Yes, comes with a basic mount and I also purchased the mtb mount for a more secure setup. It uses a boost driver to run the higher voltage emiter off only 1 cell. What is quite unique about the light unlike most other lights is that all modes are fully regulated, so high at 1000 lumens will not step down unless the battery can no longer sustain it. Most lights show off powerful lumens but can’t sustain the output for more than a couple of minutes. The warmer and high CRI tint is very similar to car halogen headlights, best for reducing glare and adding superior definition and clarity on the road. The heart pulse feature is great for city commuting.

I haven’t used mine very much yet, but so far very impressed. The 26650 cell strikes a great balance of longer battery life and still keep the light relatively compact.

I have also owned and used the Fenix BC30r flashlight. Also a great option, but not cheaper and lower color rendering, as well as integrated batteries which is a downside.

Once I have some free time, will try and post a review of the Indigo on BLF.

Not quite a budget light but my Fenix BC30 is damn near perfect for me. The beam pattern is very good, floody and has a decent spot. Supposedly it optimized to not point into other drivers eyes. You can easily dismount it off your bike and it even has a remote for a “burst” mode. It’s nice when you want a bit more distance and for a short period of time. Plus the neutral color is nice.

+1 :+1:

That’s a good idea for the phone :slight_smile:

That’s cool. I’ll have to read or watch your review. If you could PM me or post the link to the review in here that would be awesome! I don’t like the sudden step down. It startles me sometimes idk why.
I was reading up about the indigo that it also has something on it to help keep the light out of oncoming traffics eyes which is neat.

I’ve been using a modded C8s with OP reflector which works well but it doesn’t spill enough or light enough.

I have a monsterflashlight (that’s the brand) that is pretty much a knockoff ultrafire 501b flashlight. If you’re curious I ordered the flashlight from monsterflashlight.com and it is under the budget light area.

350 lumen claimed. 5 modes. Was my first light. It’s all twitchy now. Tried cleaning it and it still does twitch. Pretty old too. But yeah…… oh yeah I used to use that light. That’s why I brought it up. Not bright enough.

My hybrid bike is a Giant brand (I can’t quite remember the exact model at this moment) and the handlebars aren’t aren’t circle like on them bikes you’d get at a Walmart or target.

They are more oval and change thickness from the center to the grips. That’s why I got the Twofish mount. The mounts from amazon or even at the bike shop wouldn’t fit the handles.

Other than the Indigo, does anyone know of any good mounts that will fit different shaped handlebars? That one that came with my old Thorfire C8 is crap (it came with a cell, the mount and charger. Charger also crap).

Thanks

I use a CycleBlock by TwoFish to secure a single mode C8 with a neutral emitter and a DC-Fixed lens .

It doesn’t shift modes when going over rough terrain .

I aim the light down in town and aim it higher out in the country .

I usually get an hour and twenty minutes of runtime with a Panasonic B .

jacktheclipper I have the same mount and sometimes use a stock C8s. About an hour runtime on high mode.
I also do the same when in town. I got the twofish because I was reading on BLF I think about how much better it is than them cheap plastic ones off amazon. Very sturdy mount. Was just curious what others were using.

Do you use protected cells? I use NCR18650B cells protected in my stock C8s lights. Cells often get stuck. :person_facepalming:
But it works.

If you like the idea of a floody TIR beam, but don’t like the idea of blinding drivers, you can get elliptical TIRs that will give you a wide but short beam and angle it slightly downwards. These aren’t available for the Astrolux S41, but you can find them for lights that use standard Carclo optics or even most reflectors.

What’s a TIR beam? Carclo?

Lights like the S41 that have multiple emitters use a TIR, a plastic lens that uses the principle of Total Internal Reflection, instead of a normal reflector to focus the beam. Another common option is the Jaxman E2L, the Emisar D4, a custom built Convoy S2+ Triple, etc.

Ok thank you for clearing that up for me. I’ll check them out

I use protected cells .

I have tried the plastic elliptical inserts for my C8 , but found the shard-like artifacts distracting .

I like the beam profile DC-Fix gives me because I don’t like a blinding hotspot , particularly when it.s aimed down .

This sounds like a winner. Intriguing…

Any links?

Interested in which insert you used for C8. Link or model number?

Thanks!

Sure, sorry. I just hate formatting links on BLF. Here is an elliptical triple optic that would work in a triple light such as the Jaxman E2L .

You can also find similar TIRs for single emitter lights that should work in any 1” tube light with a bit of luck.

This Reddit post should give you an idea of the beam patterns that various TIRs, including the elliptical options, can give you.

I’m putting my foot in my mouth a bit now because I can’t seem to find any elliptical optics for quad emitter lights, sorry.
