I'd heard about the Radbot 1000 tail light and decided to order one and use it for my upcoming century ride.

It is a 1-watt LED with a large reflector below the light which gives additional visibility when approaching-from-behind car's headlights hit it. This one-two combo, a super bright flashing 1-watt LED and reflector gives it a significant edge compared to other bike lights. I also want to mention that the reflector acts as some sort of insurance that in the event your batteries die on you mid-ride in low or no daylight situations, you will still have some visibility as soon as approaching headlights hit the reflector. That is significant fail-safe mechanism in my opinion, at least in dusk to night situations.

Powered by 2-AAA batteries, you can expect about 30 hours of operation according to Portland Design Works but if you use non-rechargable alkaline batteries you will likely see the light lasting up to 50 hours or more in zZz Pop mode. That's what I get. Running the light in steady on mode will greatly reduce your battery life to about 12 hours (according to Portland Design Works. I never use that mode so couldn't advise you on that.)

It comes with a variety of mounting hardware that makes it convenient to mount, either on the back of a seat bag, or attach it to the seatpost or seatstay. Whatever works best for you.

Compared to the PlanetBike Blinky Superflash Planet Bike Blinky Superflash Tail Light which uses a 1/2 watt LED, the Radbot 1000 provides twice the light.

***December 2012 edit: This light is a different model than the one I originally reviewed. I have since bought two more of this model of the light and have not had any issues with it going out after a full year of use. The light modes on the current model are not the same as the model that I originally wrote the review for. I am a particular fan of the zzZZzzPop which was not programed into the original light. For the reason that I have not had any issues with this new version and the fact that it is now my favorite light for this price range I have increased my rating to 5 stars.

***Original review:
I've owned a number of bike lights since I started commuting exclusively by bike about 5 years ago. I normally ride with only one tail light. I bought this light 4 months ago and loved it. This is the brightest light that I've owned, definitely brighter than the superflash. The addition of the reflector is also a nice touch. One thing that I noticed though was that as the light is a 1W light it drains batteries noticeably faster than the .5 W lights that I've owned. That said I would still rate the light with 5 stars.

Why then 3 stars? As a previous reviewer noted, this light has issues with going off mid ride. On three occasions I turned on the light and 2 miles later when I got home the light was out. As I don't always ride in bike lanes and I tend to ride on busy roads and some that aren't really really well lit that scared the crap out of me (luckily there is the reflector). Then two days ago I turned on the light and it blinked for 2 seconds and went off. I turned it on again to the same result. The third time I tried to turn it on, it didn't come on. I changed the batteries, still no luck.

After 4 months it no longer turns on.

I've used rear lights from Blackburn, Cateye and Topeak, but this one destroys them all. Great light patterns, sturdy mounting hardware, and the light itself is very well built. The first time I turned it on, I nearly went blind, and this was in the middle of the day. I live in Las Vegas, and I bike to work every night. This light insures that I am seen, in fact, I can tell cars behind me sure can see this light, the way they slow down and pass me without a honk or yell. This light is so bright, that I can see the illumination on the back of my heels and legs, no other light I have ever owned was able to do that. And the batteries that come with the light last a long time, much longer than the 50 hours their supposed to last, and when they die I will definetley replace them with rechargeable ones or high end energizers. As for the water resistance, I live in the desert, so that really isn't a problem for me. But still, we will see when the first rains hit Vegas again. Over all, excellent light and I highly recommend it!

My Planet Bike Superflash pales in comparison to the Radbot. Most of my riding is at night and I want to be seen come hell or highwater, and the Radbot 1000 does just that! Interestingly enough the zZz Pop mode which is what attracted me the most is missing! BUT after I sent an email to the folks at Portland Design Works here's what they had to say in a nutshell..funny kinda but most people "supposedly" felt that the seconds between the zZz and then the POP was a detriment so they took it out. Then, they started receiving emails asking why did they do that? So, they are going to make another running change and put it back in!!!! With or without the zZz POP mode this little gem commands attention and it is BRIGHT! If you do your homework as I do with every purchase of anything associated with biking you will see that the Radbot is definitely noticed. Cars give you more room and swing wide whenever they see it which is exactly what we want. I will say again that it commands attention and to me that is the most important aspect of having a taillight is to attract attention. The 1 & 1/2 second switch is great because it allows you to carry it without accidentally turning it on and draining your batteries so it's ready when you are. As for the life of the batteries, well with a 1w bulb it does require a little more juice but the run time between battery replacement or charges is negligible. I would say that the closest runner-up would be the Dinotte at several times the price. It also has a built in reflector which is noticeable when hit with headlights and that of course is another plus since we may forget to charge our batteries and should they fail you do have a backup. In short, for the price you won't find a better light on the market. For approximately $30 you won't be disappointed, so buy one today and happy riding!!!!
