Lezyne Femto Drive LED Light-Pair Black One Size

Ottima coppia di luci, leggere e robuste. Perfetta per segnalare la presenza del ciclista in strada nei momenti di scarsa luce o visibilità (alba, tramonto o foschia). Chi è in cerca di luci da usare nel periodo notturno o per tutta la durata di una uscita in bicicletta dovrebbe orientarsi su modelli con più lumen e provvisti di batterie ricaricabili.

I was searching for a bike light that met the following criteria: small, bright enough to be seen well but not blinding to others, sleek, simple, clean looking, etc. After finding Lezyne I decided to go for it and make the purchase...and I'm glad I did. Upon opening the package and un-screwing the lens for battery access, it was apparent that the design and manufacturing quality is great (9.5/10). Im also very pleased with the 5 different modes you can select which change the blink rate, or keep it on continuously. I'm a mechanical engineer and understand good/efficient/functional designs when I see them, and these lights definitely serve as a great example of this.

リアライトとして発光部が真横から見えないので、背後のアピールには弱いかもしれませんね。必要以上に眩しいのでドライバーの目潰しも心配です。また、フロントライトとしてはリフが浅く拡散するので対向者(ランナー等)に凄く嫌がられます。しかも到達距離が短いので夜道が怖いです。スイッチも硬い上に接触が悪く、押しても反応してくれない場合が多々。デザインが気に入ってはいたのですが、実用性・安全性を考えると他商品に買い換えるしかありませんでした。高かっただけに残念です。

I picked up the Lezyne Femto lights for my bike specifically because I don't ride often - maybe once or twice a month - and for that kind of use I actually prefer replaceable lithium batteries instead of rechargeable ones. Rechargeable lithium ion cells don't last forever, whether you use them or not, and require babysitting so as to not drain them completely, and not leave them charged while not in use for a long time. Add to this the fact that most rechargeable bike lights don't have an easy way to replace the batteries, that pretty much ruled all the fancy USB rechargeable lights everyone else is gushing over.These lights put out a wide circular beam, and have 5 different modes - 3 flashing modes of various speed, a pulsing mode that ramps the brightness up/down, and constant output. That gives me more flexibility than similar lights that only have 2 modes. The rear light is angled to stay horizontally leveled while mounted to a seat post. The beam is bright enough to be visible at 100 yards in the dark, although I'd probably want something brighter if commuting on busy streets with traffic and many light sources. These are strictly a "be seen" kind of lights, and I use another more powerful light for illuminating the road.I also like that the stretchy strap is not integrated into the light, so in case it breaks, I can replace it or improvise another way to attach the lights. Finally, as a bonus, the lights have a clip that can be used to attache them to straps on other gear.Overall, for my use these lights are exactly what I wanted.

Ottimi prodotti, solidi e stabili anche per uso mountain bike. Le pile, se usate le luci in modo intermittente, hanno una buona autonomia. Non ho sperimentato se la portata luminosa coincide realmente alle caratteristiche dichiarate
