![]() Do You Need a Rear Light Only or a Full Set? Rear blinkers that put out 15 lumens may seem bright after dark but are harder to pick out in full sunlight. Also keep in mind that the brighter the ambient light, the brighter the system you’ll need for visibility. A powerful front headlight paired with a blinking taillight is necessary for these situations. If you commute in the hours before sunrise and after sunset, or ride on the road or paths at night, seeing and being seen are both important. When mountain biking, the combination of a bar-mounted lamp and a helmet-mounted light will help you see through corners and more easily pick up things like rocks in the shadows. ![]() For trail use, bright front lights are most important, as well as runtime on the light. When riding on the trail at night, seeing where you are going is key to avoiding getting hurt or becoming lost. Join Bicycling All Access for more gear picks! Many options do a great job, charge fast, and are affordable. If you typically commute to work in daylight or at dawn and dusk when the light is low, these are a must-have item. Halogen bulbs can be dimmed, but occasionally they should be operated at full light output to retain the long life benefits.Play icon The triangle icon that indicates to playįor being seen a front and rear blinker set will usually be sufficient.Refer to the beam spread and CBCP to select a bulb with the intended effect. PAR bulbs come in a variety of beam spreads, from very narrow spot to flood.Keep combustible materials away from the bulb and avoid touching while in use. The light from BR bulbs is softer than that from PAR bulbs, which produce a more focused beam. Halogen infrared (IR) bulbs have a reflective coating to redirect infrared energy back onto the filament to save energy. Most PAR bulbs are halogen, which extends bulb life. Incandescent PAR bulbs, molded from sturdy parabolic aluminized reflector glass, are used extensively for residential outdoor area lighting. It is best to use BR bulbs in deep, well-shielded indoor fixtures. Reflector bulbs fit into the same medium-based sockets as common incandescent bulbs.īR bulbs are molded from "soft" soda lime glass and should not be used outdoors without an enclosure. Because reflector bulbs vary in size, check to be sure the bulb fits in the fixture housing. ![]() For example, a bulb labeled "PAR-30" is a parabolic aluminized reflector (PAR) bulb 3 3/4" in diameter at the widest point. The letter designation refers to the shape, and the number indicates the maximum diameter of the bulb in eighths of an inch. Reflector bulbs come in a variety of shapes and sizes. Restrict their use to applications where short hours of use are expected, or where there are no other alternatives. Incandescent bulbs offer significantly lower efficacy (the amount of light produced divided by input power) and shorter life than fluorescent and LED bulbs. When selecting reflector bulbs, compare the center beam candle power (CBCP), which indicates the intensity a the center of the beam. A spot bulb will have a narrower distribution with greater intensity at the center of the beam than a flood bulb with the same wattage and bulb shape. ![]() The shape of the light beam is cone-like and can be specified in a range of beam spreads from narrow spot to wide flood. Incandescent reflector bulbs contain a reflective coating and therefore provide directional light. ![]()
