Incandescent bulbs, in layman's terms, refer to quite simple structures that give a radiant sheen and steady light. An incandescent bulb's core has two metal contacts at the bottom of the base, and this is where it gets its power. Incandescent lighting devices are designed with a wide array of voltages and sizes, ranging from 1.5 volts to about 300 volts. These devices usually do not entail any external regulating equipment and are noted to incur much lower manufacturing costs. In addition, incandescent lights such as the halogen G9 light bulbs, work well on both alternating and direct currents. These qualities help to make the incandescent lamp a popularly-used household and commercial lighting material. It also is a preferred material for portable lighting uses, whether they are utilized as car headlamps, table lamps or electric flashlights, a well as for outdoor and indoor advertising and decorative lighting.
According to lighting experts, halogen light bulbs are essentially incandescent lamps in their design and construction, and operate relatively like standard light bulbs. Though, these are quite smaller than their other incandescent relatives, they are known to offer a better lifespan, as well as produce higher and much steadier lighting outputs. A halogen light bulb is best noted for combining with tungsten, especially when the temperature of the medium is sufficiently high. Because of this trait, the generated tungsten vapor is recycled back to the filament, and not simply deposited or stored on the inner walls of the envelope.

G9 light bulbs, according to lighting experts, are designed with a pin base that has two contact pins on the underside of the bulb. These pins are then given a G or GY designation, and the corresponding number refers to the center-to-center distance in millimeters. For instance, a 4 mm pin base will then be designated as G4, or GY4 light bulb. Among the more common G or GY light bulb dimensions include the G4 (4 mm), G6.35 (6.35 mm), G8 (8 mm), G9 (9 mm), and GY9.5 (9.5 mm). In these designations, the second letter will indicate the pin's diameter.
A G9 halogen light bulb is often utilized as a downlight or spotlight, and these have qualities which are similar to the typical 12 Volt halogen bulbs. However, the G9 operates at mains voltage, which means that these do not require a transformer to lower the voltage down, and also indicates that these can be dimmed through the use of conventional dimmers. These halogen light bulb variants are known to be efficient lighting instruments, because they deliver more lumens per watt than the standard tungsten lamps. However, it would be solely up to the user to use the appropriate wattage setting in order to attain the desired lighting levels.
Halogen G9 light bulbs are also safe to use, and do not emit considerable amounts of harmful ultraviolet radiation (UV), contrary to unverified consumer reports. While a conventional incandescent lamp generates about 75 micro watts per lumen of ultraviolet radiation, and unshielded halogen emits 100- 200 µW/lm, some manufacturers and product testing firms now require that halogen lamps and bulbs incorporate a glass shield, to help in significantly bringing down harmful UV emissions to safe and negligible levels. For outdoor use, these halogen lighting variants also offer a steady, brilliant light radius that helps to best illuminate your entire yard or driveway. The light generated by these devices is truly powerful, and it often only requires one well-placed light bulb or lamp to achieve this. For those who have a halogen light fixture outdoors, you'll notice that when the bulb starts to fade out, the difference would surely be like night and day. These lighting variants make for dependable home security devices, and serve to liven up the back or front yard with steady yet gentle lighting.
