Rated 3 out of 5 by from Good for what it is But I think they held out on providing a much better light. They waited for the 80 lumen to come out. Of course now they have the 100 and 150. I have all 3 but the 80 lumen is my preferred. The main problem with this one is that it doesn't have a diffuser. So it's pretty much a straight powerful beam shooting directly behind you. The diffuser significantly adds width and side visibility. Even though it's a little more expensive I'd look at the 80, 100, or 150 lumen version of this light. Other than the the construction, buttons, charge time etc are all excellent on this light. Very well built.

Rated 5 out of 5 by from I CAN BE SEEN!!! I ride a 12 mile stretch of HWY 30 to work. In the mornings it is dark the entire way. I've had many co-workers comment on how well they can see a mile down the road. I started out with one light but now use two just for my own sense of being seen. They are well constructed, very bright, and have multiple modes to choose from. Charging is through a simple USB port and the charge lasts much longer than other rear flashers that I have had.

Rated 4 out of 5 by from Great light, just wish the clip was a little longe I really like this light. I'm coming from a PlanetBike 7 LED light that was pretty decent but not great. I definitely get more room on the road at night with this one. It's significantly brighter. It lights up reflective signs from at least 3/4 of a mile away. The only thing I wish was different was the length of the clip. It doesn't fit securely to my saddle bag so I had to purchase a spare seatpost mount for my recreation bike (the original mount is on my commuter). Highly recommended.

Rated 4 out of 5 by from Great daytime and nighttime rear light I do a lot of road riding on public roads, so I wanted a light that would get the attention of drivers even in daylight. This light fits the bill. There is a reason so many bike blogs recommend it.

Rated 4 out of 5 by from Great visibility long life Great high visibility but as another reviewer noted, it is best when viewed directly from behind, and visibility is much less from an angle or the side. Also, it is so bright directly from behind it is not good for group rides even when set on low. The charges lasts me all week.

Rated 5 out of 5 by from Bright Light, Can Be Seen Clearly Day and Night Very good light, good price, can be mounted on a number of places on your bike. When on flash mode, can be seen during daylight hours very clearly. Also when on steady light can be seen clearly. Have not had to recharge and it's been at least eight weeks since the original charge. I bought three, one for wife's bike, son's bike and mine. No complaints, only kudos. Cygolite Hotshot SL 50 Rear Bike Light, does the job, I am very pleased with this product.

Questions & Answers

Does it clip onto a backpack taillight strap?

Asked by: Jenerator
Yes, it does have a clip. It's a little short for my saddle bag so depending on how wide the strap is it can work.

I see at the Cyrgolite site that a bike rack attachment is available.  Can I purchase this through REI along with the light?

Asked by: bike2much
