How Lux and Lumen affect lights
View larger
Lux rating

Lux rating measures the same intensity of light over a given surface area, which is ideal for front lights as the width of the beam pattern is as important as the strength.

Combining Lumen with Lux

A Lumens rating is simply an indication of the width of the beam at its widest point. The behaviour of a light is best described when combining the Lux and Lumens value. See the left side chart to view the Lux to Lumens conversion chart and how various combinations behave when riding.

Light modes

Smart front lights come with various light modes to assist the rider in various cycling environments. The lights includes constant and flashing modes which mean steady and on, and flashing to give greater awareness to other road users to your presence. The range of lights can also offer low, medium, high and flashing modes to accommodate a variety of riding environments.

The light itself is decent and gives enough light to spot those pesky potholes well in advance. Only gripes are that the blinker mode is a bit too fast and is more like a strobe light which can be disorientating. The other gripe is that the bracket is excellent except it doesn't hold the light on very tight so I would recommend using tape or rubber bands to add a bit more security to prevent it pinging off on those rough roads and getting run over. This seems common on a lot of lights from my experience, my friend recently lost a £45 light for the same reason so this isn't a case of you get what you pay for and this light is just as good as his was.

Amazing how the technology has changed over the last few years. in 2007 I bought a Cateye triple shot pro for £200 which has 3 bright LEDs and a Li-Ion battery pack for about 4 hours use. This smart light seems about as bright as 1 of the triple shot LEDs which for £12 is amazing. It also lasts for 12 hours on max brightness which again is amazing. It is a quite focused spot with a large halo which works well in town. it would work ok for country roads but not MTBing single track etc. but that is not surprising. The flashing setting is also very bright. Almost too bright. I don't think you really need anything brighter as a "be seen" light. Thoroughly recommend this. Though top top: make sure you get the black one not the white one. I have both and find the white one is slightly translucent which bleeds a bit of light through the top which is distracting when riding in the dark. The black light is fine though with no light bleed.

I have one of these Smart Lunar 25 Lux lights as well as the allegedly brighter Smart Lunar 35 Lux Front Light. As noted by one of the other reviewers, this 25 Lux light seems the better light by far. It has a broader beam than the 35 Lux equivalent. It does seem a little dimmer, but not by as much as one might expect given the difference in rating. I regularly cycle along an unlit canal towpath. With the Smart Lunar 35 Lux light, the light beam was so narrow that I had to significantly slow down, as the edge of the canal was not adequately illuminated. No such problems using this 25 lux light: the full width of the path is illuminated. And with the light on it highest setting I can see far enough into the distance; not quite as far as with the 35 lux, but far enough.

This is the first light I have come across in this price range that I have felt comfortable using without also having a British-Standards compliant old-fashioned incandescent cycle lamp fitted as well.

Since getting into cycling more seriously a few years ago I have always bought Smart lights after owning Cateye when I was younger and not being that impressed with them but also because of the value of Smart lights and also the fact that their brackets fit well.

In fact I think my 1st purchase from wiggle was a 1 Watt Smart "Egg" front light. Boy - have things improved since then but sensibly the brackets have remained the same or very similar.

The brackets are much improved over their earlier models which used to have a "quick release" type lever to secure. Sometimes this could work loose. This new and improved design uses a "screw" that is done up by hand but completely eliminates the possibility of it working loose, even over our shocking roads.

Anyone who complains about this simply isn't installing it correctly.

IMO these are road / commuting lights. However I now have 2 but not yet tested. 1 will be shined down and in front to illuminate any debris or postholes and the other will be angled straight ahead so that cars see me coming.

The light with bracket weighs 129 grams. As far as I can tell it is exactly the same size as the Lunar 35 but weighs 10 grams less.

One advantage of this is it seems to have a wider spread of light than the 35 that is very laser like.

If you want an offroad light then I suggest using one with a separate Li - on battery pack. These can be bought from China.

However for a very decent road / commuter light you simply cannot go wrong with these at the bargain price I paid.

** Smart are owned by Fisher Outdoor Leisure if you need to contact. They have brands such as SRAM & Rockshox under them so definitely a very good cycling pedigree. HTH

First, the good bits...
It's a light. It works when you switch it on, and it uses standard AA batteries, so no faffing about with chargers unless you want to use NiCad rechargeables. The advertised run-time - which I haven't tested - should be good enough for a whole night's ride if you give it a fresh pair of batteries before you set off. The mounting bracket is very good, although if you are taking the bracket itself on and off in the dark, watch out you don't drop the little thumb-wheeled bolt or the threaded rod it screws into. If you leave the bracket on the bike this won't be a problem of course, and the light itself clicks in and out of the bracket nicely.

(A word on batteries though: as any photographer will know, alkaline batteries perform particularly badly in the cold, fading in voltage rather quickly. For winter riding one would be much better off using NiCad or NiMH rechargeables, or if you don't mind spending the money, non-rechargeable Lithium AA batteries last better than anything in either warm or cold weather.)

Now the bad bits...
I bought this light because it was relatively cheap, and yet it was said to have a wider beam pattern than the Lunar 35. Unfortunately, the beam pattern is still far too narrow for me. It throws a little spot far up ahead, a spot so narrow that is difficult to even align that spot where you would want it to be. You could angle it right down towards the front wheel, but then that defeats the object. I should say that I already had front lights that would make me seen by other road users, and I wanted a light that I could see by. This doesn't really work for me in that respect.

Before I got this light I had been using those £3.99 RING LED stick lights - the ones with three AAA batteries inside.
