Comparison Bailong STOP 198-5LED vs Bailong LY-17-XPE

The type determines the purpose and configuration of the lantern.

— Velofara. A device similar to car headlights and designed to illuminate the road in front of the cyclist, as well as to increase its visibility. In many countries, the use of a bicycle headlight at night or in low visibility conditions is mandatory; and even if there is no such prescription in the law, driving without lights in poor visibility is simply unwise and unsafe. The headlight, usually, is mounted on the steering wheel and rotates with it; many of these devices have a strobe mode to further improve visibility.

— Flasher. Auxiliary lamp mounted at the rear of the bicycle. Usually, flashing lights are made red (although there are other colours) and are not intended for lighting, but solely to make the cyclist more visible to other road users. Unlike headlights, such equipment is rarely mandatory even at night, however, from the point of view of traffic safety, it is much more effective and preferable than simple reflectors (reflectors). Note that, despite the name, flashers do not necessarily work only in flashing mode — usually, the design also provides for a constant light mode.

— Velofara + flasher. A kit that includes both of the devices described above — a bicycle headlight and a flasher. The point of this option is that the cyclist can purchase both the front and rear lights at once, instead...of buying them one at a time. On the other hand, buying separately gives you the opportunity to choose the lights at your discretion, while in this case you have to rely on the decision of the manufacturer. Therefore, the “bicycle headlight + flasher” kits have not received much distribution.

The number of individual light emitting diodes (LED) in the bike light (see "Type").

A larger number of LEDs, on the one hand, makes it possible to achieve greater brightness of the headlight and reduces the likelihood of its complete failure (the failure of one LED does not lead to a loss of lamp operation). On the other hand, the technical features of modern LEDs are such that manufacturers prefer to put one bright single-chip LED instead of several case ones into powerful “long-range” bicycle lights. On the third, there can also be several single-chip LEDs, to increase reliability and provide additional adjustments (for example, changing the brightness by turning on / off individual LEDs). Therefore, only lamps of the same price category should be compared by this parameter. At the same time, “multiple-charged” models, in addition to the described advantages, also have disadvantages — they are, usually, more complicated, more expensive and larger.

The number of individual operating modes provided in the bike headlight (see "Type"). Usually, this parameter takes into account all available adjustments: for example, for a model with 3 brightness adjustments and the ability to work in the stroboscope format, 6 modes will be indicated (3 brightness values \u200b\u200bfor constant light and the same for a stroboscope). A specific set of modes in each case should be clarified separately, but in general, the more there are, the more options for use the headlight suggests, the higher the likelihood that an unforeseen situation will not take the owner by surprise.

The number of brightness modes makes it possible to adjust the intensity of the flashlight and adjust it to the necessary needs. Accordingly, the more modes, the more flexible options for using the model (even not only in cycling needs). So the most popular are models with brightness control in 3 or 4 positions.

The type and number of batteries used by the bike light.

All elements, except for the proprietary batteries (see below), are removable and, usually, quickly replaced; many of them are available in two versions — disposable batteries and rechargeable batteries. The advantage of batteries is their low cost, but they need to be bought regularly; rechargeable batteries are noticeably more expensive, but once you buy a kit and a charger, you will no longer need to spend money on batteries.

— AA. One of the most popular modern standard sizes. However, in bicycle lights, such elements are used infrequently — in particular, because of the relatively large size. There are many brands of AA batteries on the market, differing in capacity and, accordingly, operating time.

— AAA. A smaller version of the AA batteries described above. Due to their compact size, they are well suited for bicycle lights; and the capacity of such batteries, although rather low, is quite sufficient, taking into account the specifics of use (flashing lights most often do not differ in significant power consumption).

— CR2032. One of the most popular and largest types of coin batteries, with a diameter of 20 mm and a thickness of 2.3 mm. At the same time, the dimensions of such batteries are very compact, which, combined with good capacity specs, makes them very...convenient for flashing lights. Typically, CR2032 cells are sold as disposable batteries.

— CR1025. Another type of coin battery is 10 mm in diameter and 2.5 mm thick. Due to their smaller size, they are noticeably inferior to RS2032 in terms of capacity, which is why they are used very rarely — mainly in flashing lights of low brightness, created with an emphasis primarily on compactness.

— LR44. Coin batteries (usually disposable) with a diameter of 11.6 mm and a thickness of 5.4 mm. The features are similar to those described above CR1025 but they are even rarer.

— LR01. Also known as LR1 or N. They are produced mainly in the form of disposable batteries, they are cylindrical, 30.2 mm long, and 12 mm in diameter (thus, LR01 is shorter than AAA battery, but noticeably thicker). Such batteries are considered optimal for devices with high current consumption. However, such devices are relatively rare among bicycle lights, and therefore LR01 has not received much distribution.

— 18650. Elements are usually made in the form of lithium-ion rechargeable batteries. Similar in shape to AA battery, but larger, with higher capacitance, and a higher voltage of 3.7V. 18650 cells are designed for high-power devices; therefore, in the case of bicycle lights, such power is a sign of a high-end model, with very high brightness levels and a long battery life. There are few such models on the market.

— Proprietary rechargeable batteries. This category includes all proprietary batteries that do not belong to any of the standard sizes, and often non-removable ones. In the case of bicycle lights, the convenience of the battery lies in the fact that it is immediately supplied in the kit. On the other hand, such a battery in the event of a discharge cannot be quickly replaced with a fresh one. However, the battery life is usually quite decent.

The number of individual light emitting diodes (LED) installed in the flasher (see "Type").

A flasher does not require high brightness, so several LEDs are usually installed in such lights based on specific operating modes: for example, a pair of LEDs can flash alternately, several in a row provide the effect of “running lights”, etc. At the same time, one LED is enough for use for its main purpose.

The number of operating modes provided in the flasher (see "Type").

The presence of two modes, usually, means the ability to work in constant light mode — in some cases this format is considered more preferable (although the blinking is still more noticeable). And if there are more than two modes, then the flasher also provides more specific options (for example, “running lights”).

The presence of a flashlight USB-portused to charge the battery. Note that this can be either a full-size socket or a smaller version — miniUSB or microUSB; in this case, there is no fundamental difference between them. Any such connector makes the flashlight independent of branded chargers and allows you to charge it from any USB output — for example, in a computer or laptop. In addition, there are also separate chargers with USB ports that can be connected to sockets or car cigarette lighters. Thus, for many cyclists, this particular charging method is preferable.
