Electron F-300 front light



Weathertight light that will work on short stretches of dark path as well as around town

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 Electron F-300 Lumen front light may be small, but as far a light goes, it certainly packs a decent punch.

A single LED with a claimed 300 lumen output, the light should be able to guide you through some dark alleys where streetlight is poor. An output of 300 lumens is never going to see you that far in the pitch black, but it's perfect for urban locations.

The light has a fairly standard three-mode system, offering high, low and pulse. All three modes have their uses. Low was great for riding around at dusk in town because it was perfectly bright enough to make me visible to cars. The pulse was used when visibility was a little poorer and the pulse is quite subtle on this, which I liked. It never made me feel like I was at a disco, yet was obviously flashing. I found the high mode performed surprisingly well on an unlit coastal path I cycle on quite a lot.

The battery life claims seem to be pretty true to real time use. It did hold out for two hours when on high and longer on pulse and low. There is a battery indicator on the power switch which uses traffic light colours to indicate the current charge.

Charging the light happens via a micro USB cable, which takes a couple of hours. There is a really weathertight rubber cover protecting the connector from the elements. It's on the bottom of the light, so helps protect it from knocks as well.

As far as mounting the light goes, it's pretty simple. It comes with a quick release mount (or you can buy the helmet mount) and it should fit most handlebars easily enough. However, releasing the light from the mount itself isn't as easy. I ended up just taking the whole mount off when it needed to be charged because it was much easier than just releasing the light from the bracket.

The power button is situated on the rear of the light, so facing the rider. It's in a great location for pressing to turn on or change mode. It does take some getting used to the quick two presses needed to turn it on though.

The light beam itself is fairly decent. I kept it on low for riding around well lit streets and found it gave off a good beam. The real test happened when I took it on a three-mile section of unlit cycle path. I was pretty impressed with it as it lit up the path reasonably well in front of me. I know the path and was happy to keep my speed up with the light.

The light projects right out in front of you and doesn't have any glare for the rider, which is a bonus. A lot of lights can be distracting when you see them out of the corner of your eye.

As for the waterproof claims of the light, which is that it is 'robust' and 'water-proof', I have to say these are very true. I had ridden my bike, washed it and put it away, only to go outside three days later to see the light on the soggy grass. It had been left in at least two days of solid rain and lived to light another day.
