Cateye Omni 5 HL-LD155 front light



If you need a long burning and bright light for commuting or as a backup, this is well designed and good value

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

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.

How much is it? £17!!!
I owned a similar designed CatEye lamp which also had the switch on the end. An earlier design had the switch on the back. The switch on the end was so sensitive that it kept switching on if I put it in a pocket or bag, so it used batteries like nobody's business. Without any particularly rough handling within a month the rubber cap on the switch had cracked and become detached. The switch failed to work.

The kidney-shaped lights sold as RSP (currently £4 at Evans) or £8 the pair from Wilkinson are a much better buy. Smart do them (£5 for the rear one). The swicth is on the back and very can be rarely is switched on accidentally.

Good point FMOAB… not being too pedantic at all

Not wanting to be too pedantic, but "a near full 360 degree range of visibility"? 180 degree surely?
