Illuminating The Night

As we know, the two biggest areas of concern while riding at night are us seeing the road, and cars seeing us. Purchasing a light that can address our concerns can sometimes be more overwhelming than purchasing the bike itself. Here is a guide to help with the decision of what you should look for in a light and how you should more effectively use your light.

The most common way that bicycle light companies rate the brightness of their lights is based off the measurement of lumens. Lumens is the measurement of luminous flux, which is the total output of light in all directions. So when we talk about bicycle lights, we are looking at the brightness that is being projected forward. For example, a light that may not look as bright but has a wider beam may have the same lumens as a visibly brighter but narrower beam.

Typically, lights are sold on a dollar- by-the-lumen basis (more lumens equal a pricier light). You must be careful while shopping for a light, because most companies will have a 1000-lumen light available for between $130-$200, while you might be able to find the same amount of lumens in a head lamp for about $20. Lights that have the ANSI FL-1 Standard logo on their packaging follow strict compliances that make the tested lights exactly what are advertised for lumens, waterproofing, run-time and impact resistance. There are a handful of cycling light companies that advertise being ANSI FL-1 compliant. Buying an ANSI FL-1-compliant light will guarantee that you are buying what you paid for; unfortunately, they are few and far between for the time being.

Okay, technically there’s not a right or wrong way of using a bicycle light, except making sure you have the red light facing backwards and the headlight facing forward (we’ve actually seen cyclists riding at night with the headlight mounted rearward on the seatpost). Most riders believe that having a flashing front and taillight is the best when it comes to maximizing your visibility. You will, without a doubt, increase your visibility with a flashing light. The downside with using flashing front or rear lights is the decrease of depth perception and increased disorientation that can result, especially with brighter lights. For the best safety results, during the day it is best to use the flashing or strobe features on your lights. During the night, using a pulse or solid front and rear lights would be optimal to increase your visibility of the road in front of you without disorienting the riders or drivers either in front or behind.

Any way you can improve the visibility of your presence while riding is key to keeping drivers and other cyclists aware of your presence. Blaze Laserlight helps cyclists announce their impending presence by shining a green laser image of a bicycle on the road in front of the rider. This laser image is especially helpful when riding next to a car in slow traffic by putting the image almost in front of the drivers.

The dual-function Blaze Laserlight is also a standard bicycle light with a 300-lumen LED lamp. It uses a sleek, well-made metal mount that is easy to clip and unclip onto the bracket for quick installation after charging. It has three modes, including full power, low power and flashing, while the laser light has two modes—flashing or solid.

Blackburn has been synonymous with everyday commuter, urban and touring products for much of their 40 years in the cycling industry. A main focus of Blackburn is developing front and taillights for most needs and price ranges. Though they do not make any extreme high-powered lamps, they produce commuter/urban all-in-one front lights. The ANSI FL-1-certified Central 700 is their highest-powered front light that at max output shines a 700-lumen beam.

The Central 700 uses a single Cree LED for a single beam of light, but also has a lens that improves ambient light around the main beam, as well as side lighting for extra side visibility. It has five light functions and a battery-level indicator built into the top function button. The Central’s mounting system is universal for any mounting position using the same OEM bracket for either the handlebar or helmet. If you would want to mount the light onto an action camera mount, you also have that option.

The Fly6 features the same light and camera function as the Fly12, but it keeps an eye on what is behind you. The Fly6 uses a 30-lumen light with a 720p camera that attaches to your seatpost. The Fly6 will last up to six hours of run-time with both the light and the camera on for all-ride security. Both the Fly6 and Fly12 are waterproof and arrive ready to shoot with memory cards (16 GB for the Fly12, 8 GB for the Fly6).
