Planet Bike Beamer 3 LED Bicycle Light with Quick Cam Bracket Mount

It seems like a good product after 6 weeks of weekday commuting. It's bright from the point of view of being seen by other road users. It does produce a reasonable beam of light, but not enough to see by in the dark (but I didn't expect that). I also have a Blaze 1/2 watt from the same company and the Blaze is more expensive and isn't really much brighter so I'd say the Beamer is much better value for money. The handlebar clip works well and is easy to adjust. For narrower bars the band can be shortened with a tie-wrap style ratchet under the mount point. It fitted my bars of 25mm diameter. The light slides on and off the bracket easily. To get it off there's a little plastic tab which you push down much like many other products of this type.
It's too early to say if it's waterproof or how long the included batteries will last, but it's holding up well after around 10 hours running time.

This is a good light. It installs easy, comes with a battery, and provides enough brightness. It is very easy to quickly remove it and put it back on, in case you don't want to leave it on your bike while it is locked up. So far this has been exactly what I needed and worked perfectly.

This is a great light for urban riding. You would not need anything brighter unless you were riding in pitch dark. The flashing mode is visible for a great distance. It is also very easy to install. I leave the bracket on my handlebar right beside my heart rate monitor. It takes up very little room and is very unobtrusive. I almost purchased a more expensive light because it had 5 instead of 3 Led's - don't bother - this is a great light.

I bike in reasonably dark suburban areas and I need my bike headlight to see. The Planet Bike Beamer 3 LED unit gives a good bright very precise circle of light that lets me see the road surface I'm about to hit. It has cut outs on the left and right to allow light to spill to the sides a bit - illuminating my handlebars (but not enough to read the gear indicators). I like this - it helps orient me. The "Quick Cam" bracket mount is a bit fiddly to get adjusted, but once I did, it allows me to quickly take it on and off and, when on, lets me aim it up or down without undoing it (and it stays put).

The only negatives I can see are that 1) I'd prefer it to default to steady beam, not blinking. This is a quibble. 2) I'd prefer more light spread. I think they sacrificed some spread in exchange for having such a sharply defined circle. Maybe I'm wrong and it's a function of those beefy lenses on the front.

All in all this is a great item for the price and gets the job done fine of illuminating my path when I bike at night.

My wife had the beamer 1, and that was a bright light. The beamer 3 is that much better. You can't go wrong with this light, and well worth the price.
