The Omni 5 is a brand new front light from Cateye and offers a near full 180 degree range of visibility making it a a very good commuting light in its own right or as an emergency backup light to a brighter main beam.
Inside the new lens are five LEDs and the light they produce is reflected through prisms carefully placed to split their beams. This ensures there is a healthy amount of light reflected sideways as well as straight ahead, and really seems to work.
When you're commuting through town you don't just want a front light to be visible from ahead, but you want to have good side visibility, particularly at roundabouts and other junctions where traffic might be approaching from the side. The Omni 5 spits out a huge amount of light in all directions and helps you stand out far more than many other lights... it's a confidence boost on busy and dimly lit streets.
The light is easy to fit to the handlebars with simple tool-free FlexTight. The light unit slots into the bracket and can easily be removed. When fixed in place the light is very stable - it doesn't bounce around at all.
Located at the side is the button that operates the light. A long press turns it on and off, a short press cycles through the three available modes, rapid, flash and constant. Battery life is impressive making it a light you can fit and forget for quite a while (of course depending on how long your commute is).
In rapid and constant the battery life is 40-hours while in flash mode it's a huge 120-hours. That's from two AAA batteries that are easily replaceable when time comes to swap them for a fresh pair.
It's a compact light and doesn't take up much space on the handlebars. It's an excellent choice for city commuting cyclists and its huge range of visibility makes it a clear winner over similar lights that only project light forwards.
And as well as commuting duties, it's also a good backup light for cyclists doing a lot of training in the evenings after work, complementing a brighter main light.
They produce the same light for the back as well, and a pair would make a good setup.
If you need a long burning and bright light for commuting or as a backup, this is well designed and good value.
