Luminaires with LEDs That Look Like High Pressure Sodium Lamps
While “Can I get luminaires with LEDs that look like HPS” may seem like a bizarre question, it is not. The question came from a customer who needed new low-maintenance, energy-efficient lighting that matched his existing fixtures. The answer? LEDs that look like HPS (high pressure sodium) lighting. Why would anybody want that? HPS is 2200K lighting, which means its light is distinctly yellow. HPS is also about 22 CRI. That means the emitted light doesn’t do a terrific job rendering color. Using HPS limits our ability to see the colors of objects underneath it. High pressure sodium vapor lights are often used in horticulture because they emit light that supports plant growth and flowering. They operate at high pressure and have a unique light spectrum that differentiates them from other lighting types.
Historically, we transitioned from oil and gas lamps to incandescent lights, which were a significant improvement in terms of brightness and usability. However, incandescent lights have largely been replaced by more efficient technologies like fluorescent lights and LEDs. Sodium vapor lights, including high pressure sodium lights, are a type of gas-discharge light known for their operational characteristics and efficiency. Despite their historical use, sodium vapor lights are now being overshadowed by LEDs, which offer superior efficiency and light quality. Fluorescent lights, for example, are commonly used in large spaces such as gymnasiums, warehouses, and commercial buildings due to their adaptability and efficiency. This shift highlights the ongoing evolution in lighting technology, moving towards solutions that offer better energy efficiency and environmental benefits.
Why Would Somebody Want Luminaires with 2200K LEDs for a Warm Yellow Glow?
The primary reason someone might want LEDs that look like HPS is aesthetics. If all the light around an area is HPS, LEDs that emit higher Kelvin, white light will stick out and reduce the ambiance. In historical districts—depending on the age of the district—the original lights were oil or gas lamps that emitted 1850K light. The light had a extremely yellow glow to it. Eventually, oil and gas light sources gave way to the first incandescent lighting, the first source of electrical light. The early sources of incandescent light used heavy filaments, so those lights emitted a warm glow, just like the gas and oil lights. HPS, which eventually replaced incandescent, emits yellow light, too, though it is measured at around 2200K. High pressure sodium bulbs, despite their long lifespan, require replacements and ongoing monitoring efforts, and are vulnerable to physical damage due to their glass construction. Given the long history of this yellow-orange light, you won’t likely want to introduce bright-white LEDs in a historic district.
The warm yellow glow produced by HPS lighting has an aesthetic appeal that is hard to replicate with other lighting technologies. In comparison, the low pressure sodium lamp is the most efficient variant of HIDs, with source efficiency ranging from 60 to 190 lumens/watt, but it has a poor color rendering index compared to HPS and LEDs.
