AA-powered tail lights.
It looks like the manufacturers rediscovered that AA batteries are much better at powering high intensity rear lights than their AAA poor cousins. Considering that a large minority of people are not getting on the USB-rechargeable bandwagon for whatever reasons, I noticed couple of new lights for this season. They are Blackburn Local 20 Rear Light & Serfas 9-Led Cross Pattern Bicycle Taillight - TL-STP:

Are they any good for daytime riding?

It's interesting that they've gone to AA. That makes more sense to me - AA has a lot more capacity so less recharging.
At 35 and 20 lumens I do not think they're good for daytime though. Some of the daytime lights rated at 80 lumens or so are questionable if they're bright enough.

MY B&M 4D senso Plus Toplight uses 2 AA (senso mode, switch position 3, the light comes on at night , once you start moving ,
then shuts off in a few minutes once you stop )
Toplight Means rack mount.

No blinking mode, not that bright, not transferable between multiple bikes, requires a rack & overpriced.

Well, the original Cygolite Hotshot which I have has 30 lumen & is very visible during the day. I know because I have one. Its beam is too narrow so while it's great for the night, daytime is not hotshot's forte. It looks like the Serfas has that serrated lens for wide distribution & 5 more lumen brighter.
Lumens is the total amount of light put out by the light. A light that's to narrow but otherwise bright enough for daytime riding would not be bright enough if the beam was made much wider.

Why would you start a thread "asking" if it's ok for daytime then insist that it is?

Thanks. Looks like Serfas doesn't cut it either. I spent some time reading this thread: https://www.bikeforums.net/electronic...ytime-use.html and the consensus seems to be that a good daytime light starts with something like 60 lumens. At least that the point where the manufacturers are starting to make such claims. I'll probably be getting Cygolite Hotshot Pro 80. It has the best battery life plus I've had a pretty good experience with the original Hotshot and all four of my bike have mounts for it.

Yes, Axiom 60 & 80 from Performancebike, couple of Serfas & Blackburn Flare R. Perhaps some others. However, the it looks like the Hotshot got a better (i.e. longer lasting) battery. And it's on the cheaper side too.

I know (have) the Axiom 60, but was unaware of an Axiom 80. Is there really an 80 lumen taillight by Axiom? Link? Thanks.
Btw, I now have both Axiom 60 and Serfas 60, and as ItsJustMe said, they are almost identical, but they have slightly different modes. Both are nice. My only complaint is neither of them have rear rack bracket.

That choice is probably the brightest when viewed directly from the rear
I use Planet Bike Super Turbo Flash. Brighter from an angle but not quite as bright as the Hotshot from a direct rear angle. It has a decent battery life.

Turbo Flash is great for the nighttime but not good enough for the day. I have regular Superflashes & use them as back up lights. One can only squeeze so much from the meager AAA alkalines. AAs are a different story. Perhaps I'll get the Serfas as a rack light for my utility bike.

Your taillight must produce hundreds of lumens of red light to be plainly visible to motorists on sunny days in traffic. No regular taillight will cut it. My old Dinotte 140L (~120 lumens) ran off 4AAs and was more than adequate at night, but did little to make me conspicuous in the daytime.
There are only 2 truly daytime-capable taillights AFAIK, linked below. The DS-500 is superior in that it's output in flash mode can be reduced for responsible nighttime use, whereas the DDR output in flash mode is fixed and will be blindingly bright to motorists behind you at night (DDR output can be reduced to 10% in constant/steady mode only). The DS-500 is about twice as bright (800 vs 400 lm) and has a wide range of flash and steady output modes, adjustable in pulse length and intensity.

Short of spending hundreds on one of the lights above, OSHA lime yellow high visibility shirts/jackets are pretty good at capturing attention in the daytime - at least as good as "regular" taillights but require no recharging:

Got Serfas 9-Led Cross Pattern couple of weeks ago & it's an excellent rack light. Easily as bright as the original Hotshot with a much wider beam so it's quite visible in the daytime. The box says it's 40 lumens & I believe it. There are two of them: one with an USB port and one without. Both run two NiMh replaceable AA batteries. Or you can use regular alkalines. I got the own with USB for $3 more & glad I did because I like the port so the batteries can be charged in the light itself. I replaced the original batteries with Eneloops which have more capacity so they'll last even longer.

I use the Hotshot, and I haven't found (yet) that the beam is too narrow. I guess if I get hit from behind, that could be proof that it doesn't work. Until then, I don't have proof that it does work.

I have a Hotshot too. But it's nice to have two tail lights in case one fails. Also, Serfas has a large CPSC reflector & is a perfect rack light which Hotshot is not.
