Did going from white to red bring down the intensity of the white light? Yes, but not so much to make it useless, it's the brightest tail light I have and the brightest I've seen where I live. The only tail lights I've seen that were more noticeable were a couple of cyclists I saw who had those large 5" x 4" rectangular shaped lights with a dozen or more LED's.

Those larger lights looked like this: https://www.ledsafetylights.com/safet...p?ProductID=85 While each LED is not near as bright as my one single LED, but the combined effort of 18 leds in a large area makes the light extremely noticeable and you can see it fast from very far away...like a car or motorcycle tail light. Those are probably the best bicycle tail light for noticebility you can get currently for a light, but few cyclist want such a large light on their bikes.

I can't justify the expense right now, otherwise I would pick it up to try it out, I've added it to my list of parts for my touring rigs overhaul though.

I can't really reccommend the light I mounted on the rear of my girlfriends rack, I found out after I bought it that it has a reputation for failures, but hers has been working well, it is quite bright with a little bit of a variation which helps catch the eye. I can't remember the brand/model, I'll check when I finally make it home from work and school later today.

I'm in need of a replacement light since two of mine are pretty old and my other is a Knog that doesn't cut it in the daytime/early dusk.

I am thinking about pulling the trigger. Waterproof is a plus on it:

Ah, I see some have, up this post. I think I don't have enough seatpost with the bag there. So looks like KNOG is out.

Back to drawing board

the cycgolite has much better batteries than the other similar lights (li ion).

I've been safe for 40 years with what I've been using, but some people don't feel safe without something like that and for them they may need a large light.

Most of those USB charged lights have built-in batteries that can't be replaced, so there is a concern about the longevity. How long do those lights such as the HotShot last---or rather, how many recharges do they take before the batteries die? Also I guess after a considerable number of recharges the light will not be as bright as when they were new?

Then for the next 3 uses make sure to run the battery all the way down and recharge all the way back up for 3 complete cycles, once that's done you don't have to worry about doing full discharges and recharges like batteries of yesterday anymore.

I wonder if the clip on the Serfas light would fit any of my other spare light mount clamps I have laying around.

With an 18650-based li-ion front light, the battery itself can be easily replaced, though you have to buy the proprietary Cygolite version for the ExpiliOn light. But for rear lights that draw much less power and last much longer on a single charge, the light should easily last years.

In short, if the Cygolite Hotshot is using the same LED as the Serfas, they aren't taking full advantage of it. The Serfas is pretty amazing given its size, and they do manage to keep the runtime pretty reasonable. You're just not going to get 30+ hours out of a small light that bright but 3 to 10 depending on mode is pretty good.

I think it's cool that we have as much choice as we do. All the lights on that pole are OK, even the SuperFlash, even though it's badly outgunned, and all $60 and down, most < $40.
