6 Things to Know Before You Buy Bike Lights

Buyer's Guide to Bike Headlights
Buyer's Guide to Bike Headlights, by The Geeky Cyclist

1. Type of Cycling You Do

I’ve seen many people make this mistake during their buying process.

They go for the one with the highest lumens rating that they can afford.

While this might be the safer option to go with, it’s not always the right option and by knowing how lumens work, you might even save some money.

A higher lumens count doesn’t necessarily means a brighter bike light.

Geek Tip : You don’t need lights with the HIGHEST lumens rating.

99% of bike light manufacturers today specify the brightness in terms of Lumens, except maybe for a German company, Busch & Muller.

While there is nothing wrong with using Lumens, there is another way to do it, which is better but less talked about.

Let me introduce you to the term Lux.

Lux vs Lumens

Lumens vs Lux

What’s a Lux and why is it better interpretation of the brightness?

Imagine the car salesperson telling you that the gas tank of the car you’re buying is 20 gallons. 

Would you know how far 20 gallons will last you?

It depends on several factors, like the engine capacity right?

Lux is the measure of a light’s intensity and it affects what you see.

  • Lumens : The unit used to represent the amount of light, aka brightness emitted by a single source.
  • Lux : The unit used to measure the amount of light in a specific area, a certain distance from the source. In other words, it’s a measure of the light’s intensity.
  • Beam Angle : The coverage of the light beam in front of you. A higher beam angle results in a diffused beam pattern (lower lux), while a lower beam angle results in a focused beam pattern (higher lux). A beam angle of around 20-30 degrees is what you should be looking for.

2. Headlight Visibility Range

Like I mentioned in the section above, most bike light manufacturers specify the brightness in lumens.

Take 2 different lights with the same amount of lumens and their visibility range could differ.

It all depends on whether the light beam’s patterns, narrow or wide.

Geek Tip : For a headlight where you can clearly see 40-50 feet in front, the lumens count usually falls somewhere between 300 to 500 lumens.

How Fast Do You Usually Ride?

Let’s assume for a second that you ride at 15mph and using a light with 50 feet of clear visibility.

With that, you’ll have around 2.27s of reaction time. That’s just about enough time for you to react to any hazards in front.

3. Types of Bulbs (LED vs non LED)

Did you notice that most bike lights in the market today use LED or Light Emitting Diodes?

Well, there’s a reason for that.

Benefits of Using LED Bicycle Lights

  • Energy Efficient : High quality LED lights are 80-90% more energy efficient than traditional light bulbs which means that you’ll have longer battery life.
  • Less Heat : Up to 95% of the energy in LED lights are converted to light and only around 5% is wasted as heat. Compared to traditional bulbs, which does the exact opposite – 95% into heat and 5% into light!
  • Longer Durability : LED lights are generally don’t ‘burn out’ or simply fail. Overtime, they experience what industry experts call lumens depreciation, whereby its brightness gradually decreases.
  • Light Direction : LED emit lights in a specific direction. This property of LED enables bike light manufacturers to accurately control the light beams to shine to where matters most.

Now I don’t see any reason why you should even consider non LED bike lights!

Geek Tip : Go for LED bicycle lights as they’re small, energy efficient and last forever (well, almost).

4. Number of Lighting Modes

Most bike headlights these days comes with at least 4 modes; the standard High, Medium, Low and Flash mode.

Some goes as high as 7 like the Exposure Lights Sirius.

From my experience, it doesn’t matter how many modes are there. It’s just a numbers game for the manufacturers to look better than their competitors.

What’s more important is how you use the the light modes.

It’s important that you buy headlights with Flash/Strobe mode.

Most headlights today have them. But for some strange reasons, there are still lights without them.

Geek Tip : You don’t need a bike light with the most number of light modes.

5. Battery Life

You can still find bike lights using disposable aaa batteries today in the market.

For a longer battery life and durability, I’d recommend to go with USB rechargeable batteries. Most usb rechargeable lights either use the Lithium Ion (Li-Ion) or Lithium Polymer (Li-Pro) batteries today as they are lighter, smaller and has much more capacity.

You’ll be provided with a micro USB out from the box when you purchase.

There were major advancement made in lithium batteries in the past 5 years so it’s just not worth the effort to keep replacing batteries, especially if you use the bike lights on a daily basis.

Lithium Based Batteries are Preferred

The chart above shows why Lithium based batteries are preferred, especially for small electronic devices.

  • For the same weight, Lithium based batteries hold more charge.
  • For the same volume, Lithium based batteries hold more charge.

Size, battery capacity and battery life are relatively proportional. A longer battery life would require a larger battery capacity and hence a larger size.

That’s the reason why lights with above 1000 lumens comes with a separate rechargeable battery pack. Another reason is to avoid the battery pack overheating the entire light body.

What’s considered a good battery life?

Some lights like the Cygolite Expilion 850 takes things up a notch with a user replaceable rechargeable battery. With this, you can have the option of carrying a spare rechargeable battery if you forgot to charge.

Geek Tip : You don’t need a bike light with the most number of light modes.

6. Handlebar Mounting Options

With most bicycle lights today, the 2 most popular mounting options are using straps mounts and clamp mounts.

When it comes to mounting locations, there are various options available, depending on the design of the light.

On Top of the Handlebars​

Knog PWR Road Bike Lights

Most bicycle lights such as the Knog PWR Road and Light and Motion Urban 700 are still designed to be mounted on top of the handlebars as its the most straightforward way.

  • Pros : Easy access to the buttons, to adjust the tilt and to tighten the straps
  • Cons : Crammed cockpit, especially on narrower handlebars below 40 cm wide

Below the Bike Computer Unit​

Light and Motion Urbans GPS Mount

Some newer lights like the Exposure Lights Sirius are designed to be mounted on both on the handlebars and below your cycling computer with a separate quick release mounting kit.

It certainly looks better with this but it does come with a downside; it’s harder to access the light and buttons while riding.

  • Pros : Very clean cockpit look as the light is out of your sight
  • Cons : Buttons are not easily accessible while you’re riding

In Front of the Handlebars​

Knog Blinder Road 400 Headlights

Knog came up with a creative way of mounting the light which gives you the best of both worlds. One such example is the Knog Blinder Mob.

  • Pros : Clean cockpit look
  • Cons : Handlebars might be a little crammed if you’re using a narrow one below 40cm

Frequently Asked Questions

1. How many lumens do I need for road cycling?

The ideal brightness for a bike light is between 300 to 600 lumens. The Knog PWR Road and Lezyne Micro Drive 600XL fall into this category.

If you’re riding mostly along unlit bike paths, then you can go up to 800 lumens such as the Exposure Lights Sirius.

As I’ve mentioned above, you don’t need the highest lumens for 2 very simple reasons. If you’re riding on the road, you could risk blinding the oncoming cars.

Secondly, running on the brightest mode will significantly shorten the battery life.

2. Is it illegal to ride without lights at night?

Depending on where you’re located, it can be against the law to ride your bike without lights at night.

There are local bike laws in every state in the U.S. that regulates how bicycle lights are used. There are also similar laws in the U.K. and Germany.

While each state might have a subtle difference between them, it’s generally accepted that you should have both active and passive lighting on your bike.

For safety and visibility purposes, I strongly recommend you to use one.

3. What are CREE LED?

CREE LED lights are manufactured by an American company, CREE who is the industry leader in LED lighting.

It was started back in 1987 in North Carolina. Today, CREE manufactures top quality lights and they are widely used in indoor, outdoors and to LED lights.

Lights such as the NiteRider Lumina 1100Exposure Lights Sirius and Light and Motion Urban 650 uses CREE LED’s.
