It’s no shock that COVID-19 has introduced dramatic modifications to each enterprise. As organizations shortly adjusted to adjust to social distancing and stay-at-home orders, ridership on native commuter traces additionally declined. Consequently, mass transit companies all through the U.S. and Canada had been pressured to chop prices any manner they may and assume outdoors the field. One space the place companies can lower your expenses with out sacrificing efficiency will be discovered within the adoption of halogen bulbs for railway headlamps. With their longevity and inexpensive price ticket, halogen bulbs symbolize an untapped useful resource and make a sensible alternative for commuter railroads which can be working onerous to fulfill a optimistic backside line.

Whereas new commuter automobiles are being outfitted with long-lasting LED lights, most railcars in operation nonetheless depend on PAR46 incandescent bulbs to mild their manner. PAR stands for parabolic aluminized reflector and these bulbs are available in a variety of sizes ranging out of your common family PAR20 all the best way as much as plane touchdown lights. The recognition of incandescent bulbs is due largely to their low value (a single bulb can value as little as $15-$25). Nonetheless, of their zeal to acquire the least costly bulb available on the market, procurement departments usually bypass the potential financial savings provided by longer-lasting halogen lights.

In case you’re contemplating a swap to halogen as a cost-saving measure, listed below are three issues that shed some “mild” on the topic and assist in your determination:

By way of value, halogen bulbs are far cheaper than LED lights, which run anyplace from $100 to $300 for reasonably priced choices and as much as $1,000 for a high-end bulb. Outfitting a fleet of 1,500 railcars with 4 LED headlamps apiece may value a staggering $6 million. By comparability, the fee to outfit the identical fleet with halogen lights could solely value round $388,000.

Halogen means much less downtime for changeouts.

The adage “time is cash” definitely applies to sustaining the lighting on railcars. Altering out incandescent or halogen bulbs takes anyplace from 20 minutes as much as an hour. Though the method is nowhere close to as time-consuming as switching out LED lamps, it does require upkeep crews to take automobiles out of fee through the changeout, which may wreak havoc with commuter schedules. Adopting halogen bulbs —which final three to eight occasions longer than incandescent bulbs — is a straightforward method to reduce upkeep occasions.

Halogen bulbs provide superior efficiency.

Halogen bulbs are a sturdy lighting choice that outperform each incandescent and LED lights on a wide range of measures, together with the power to resist the vibrations of shifting railcars. In distinction to the filaments in incandescent bulbs, halogen filaments are bolstered by producers, making them much less liable to breakage. Halogen bulbs additionally evaluate favorably to LED lights, which have delicate electronics that may be disrupted by vibrations.

Along with their skill to resist railcar vibrations, halogen bulbs provide another benefit over LED lights. Whereas LED lights lack a heating aspect to stop ice buildup, halogen bulbs generate adequate warmth to maintain head lamps ice free in subzero temperatures, making them an ideal choice for commuter traces throughout icy winters.

Incandescent bulbs additionally generate sufficient warmth to soften ice buildup, however halogen bulbs actually outshine their incandescent counterparts in terms of candela output. A candela is the measurement of sunshine output at a selected distance. Over time, incandescent bulbs lose candela output, whereas halogen bulbs preserve constant candela all through their lifespan.

Avoiding “beam wander” is one other benefit halogen affords over incandescent. After 200 to 400 hours, incandescent lamps begin to sag, which modifications the focus within the reflector. Over time, as an alternative of shining a beam of sunshine straight down the center of the monitor, the incandescent lamp factors its beam of sunshine in an upward course.
