Every consumer car, truck, or van comes with lights pre-installed. Without lights, night driving would be practically impossible and bad-weather traffic would be extremely dangerous. The stock lighting kit that comes with your car is often incomplete, arriving with just enough lights to meet government specifications. Yet lighting almost always takes a back seat to other things, your sound system for instance, when it comes time for upgrades. But why upgrade lights if they haven’t burned out yet? Well it’s more than just upgrading headlights. A car with a full light kit includes additional lights such as fog lamps, driver lights, and parking lights.

Metal halide (MH) bulbs are a popular type of high-intensity discharge (HID) lamp. Metal halide bulbs emit very powerful, bright white light and generally have a higher color-rendering index (CRI) than other HIDs. They can be used either indoors or outdoors but are best used in applications that take advantage of their energy efficiency and high CRIs, such as parking lots, sports game lighting and automotive headlamps. There are many kinds of metal halide bulbs, along with many industry terms that may make it difficult to select the bulb you need. That’s why in this week’s entry, we define and discuss some important factors you should consider when purchasing a new HID metal halide light bulb.

Electronic HID ballasts are a growing part of the market. These units combine the capacitor, ignitor, and mounting brackets into a single unit along with the ballast itself. There are advantages to this design that many companies are starting to use to their benefit. One benefit is up to 25% better energy efficiency than traditional magnetic ballasts, which can add up to significant savings every year.

With the increasing push to make lighting more efficient, many designers are starting to look at metal halide and other HID (high intensity discharge) lamps as a viable alternative to fluorescent and incandescent lighting sources. Though this light source has been traditionally used in warehouses, parking lots, and other commercial areas, its use has recently expanded, making it a viable lighting alternative even in outdoor residential settings.
What are HID lamps? These lamps are compact and efficient sources of powerful light that require a ballast, much like fluorescent lamps. Also like fluorescents, these lamps use rare earth metal salts in combination with mercury vapor stored in a vacuum tube. When electricity passes through the lamp’s electrodes, the vapor and salts illuminate, producing a large amount of light in the right color spectrum. This type of energy-efficient lighting works well in general lighting situations, as floodlights, and in security areas.
HID lamps take a short amount of time to get to their brightest illumination. The temperature and pressure inside the vacuum needs to reach an optimal temperature before maximum illumination happens. Some will take only a few seconds while some may require a couple of minutes. When a lamp shuts off, many of them require a few minutes to cool down before they can be re-lit.
If you are considering HID lighting, you can do no better than pulse start metal halides. These are the most energy-efficient of HID lighting types, and their cost is becoming more affordable. Their small bulb shape allows them to offer many advantages that fluorescent sources cannot, and with their long lamp life, you will find their cost low in comparison to incandescents.

Ceramic metal halide lamps offer many advantages in higher efficiency and longer life. Halogen lamps bring a great deal of illumination to commercial spaces. However, they come with a high-energy cost and a relatively short life. This can cost commercial and retailers a good deal of money in energy and labor to keep them running. In spaces where you need better life bulb that save energy, these ceramic halide lamps are the ticket. And many retailers and commercial operations are starting to see the advantages of using these bulbs.
Another advantage of using ceramic metal halide lamps is their color quality. A problem many are having transitioning from incandescent is the changes in color that many light fixtures bring. With these ceramic halide lamps, you get excellent color from the start. You also find them in sizes that make them great replacements for existing halogen fixtures. This makes putting them into retrofit projects a breeze. With the need to keep costs down, many commercial and retail spaces are looking for affordable lighting alternatives that will keep their spaces lit without breaking the budget. These ceramic halide lamps are one way to do just that.
You can find ceramic metal halide lamps in an increasing number of sizes and shapes. This makes them great for making them replacements for high-pressure sodium lamps in existing magnetic ballasts. But, in order to get the most energy savings, you need to put them in electronic ballasts. These lamps offer long life and good light maintenance throughout their life span. With so many configurations available, they are great for retrofitting existing lighting schemes. And their long life helps balance against their higher cost.
That is one disadvantage to ceramic metal halide lamps. They cost a bit more than many other traditional light bulbs. However, their costs are steadily coming down as the option becomes more popular and demand continues to grow. This will likely continue well into the future. And the energy they save can justify the initial costs for many. Your best bet is to look at the options available and choose the lamp that suits your needs. Many manufacturers are making these bulbs and you can find a lamp that will suit any requirement you have. Some are pulse start. Others come with built-in ballast. You can get them in pin or traditional screw-in designs. Some are small while others are larger lamps. You should find a design to fit any fixture you currently have.
