Specialty and Architectural Lighting

Years ago, we published an article on the harmful effects of ultraviolet light from the sun. This article is a follow-up discussing the harmful effects of ultraviolet radiation from artificial sources like light bulbs. Ultraviolet light is naturally-occurring, and most of it reaching earth originates from sunlight. While it can...

The veterinary service industry in the USA is a large market, with pet owners spending $38.3 billion in 2023 alone for animal care and related products. There are over 100,000 veterinarians in the USA, and more support staff. While veterinarians use a variety of tools and methodologies in diagnosing and...

Ultraviolet UVB bulbs are used in a variety of medical, industrial, and other applications. There are a couple variations of UVB bulbs, based on the output spectrum of the lamp. These are referred to as Narrowband and Broadband UVB lamps. The names are somewhat self-explanatory in terms of the relative...

Summer is the perfect time to enjoy warm days and cooler evenings outdoors. But while soaking up the sun, it's easy to forget about your home's lighting. Proper lighting maintenance can improve energy efficiency, enhance safety, and keep indoor and outdoor spaces looking bright and inviting. Here are some essential...

One common question we get is whether a UVC HVAC system can help with allergies. And with spring returning to much of the Northern Hemisphere, seasonal allergies are a large concern for people, with nearly a quarter of US adults being affected. In general, a UVC air purifier installed in...

Mercury short arc light bulbs, often referred to as mercury vapor lamps, are a type of electric discharge light source that utilizes mercury vapor to produce light. These lamps are known for their ability to produce a bright, intense light with a characteristic blue-white hue. Mercury short arc lamps are...

Over the years, we've written a lot on the banning of incandescent (and now halogen) light bulbs for general service use. CFL bulbs never really caught on with consumers, but LEDs are more energy efficient than ever and can offer similar color rendering to incandescents. But despite being "banned," the...

Screen printing is a printing technique used to transfer designs onto a variety of surfaces, including fabric, paper, wood, and metal. The process involves creating a stencil, referred to as a "screen," and using it to apply layers of ink onto the printing surface. Screen printing is widely used for...

A light guide for ultraviolet curing is a component of the curing system that helps direct and distribute UV light efficiently to a specific area for curing or hardening of materials. In UV curing, ultraviolet light is used to initiate photochemical reactions in inks, coatings, adhesives, or resins, causing them...

Ultraviolet curing is a process that uses UV light to cure or harden coatings, adhesives, and inks in a wide range of industrial and commercial applications. This technology is particularly beneficial for sectors such as medical device manufacturing, fiber optics, electronics, and lens production, where precise, fast, and solvent-free curing...

With the transition from incandescent and halogen bulbs to CFL and LED, creating lighting experiences with accurate color rendering has become more difficult. While older light bulbs have a CRI close to 100, new bulbs can range from 80 to 95+, with variations in different colors. For the food industry,...

Ultraviolet water purifiers are effective in disinfecting water by neutralizing harmful microorganisms. There are two primary types — whole-house and point-of-use (POU). Each type has various pros and cons depending on the installation and usage needs. Whole-House UV Water Purifiers A whole-house water purifier treats all water entering the home,...

Ultraviolet (UV) water purifiers and sediment filters can be utilized in an integrated system to provide a comprehensive approach to water purification by addressing different types of contaminants. Sediment Filters Remove Large Particles Sediment filters are designed to remove larger particles from the water. These particles can include dirt, sand,...

Ceramic xenon light bulbs provide enhanced precision for specialty applications. These bulbs are designed for applications such as endoscopy, video projection, microscopy, spectroscopy, solar simulation and machine vision. With their unique construction and powerful illumination, ceramic xenon bulbs play a pivotal role in improving the quality and efficiency of tasks...

One of the distinct advantages LED bulbs have over CFL is their better performance in winter and in cooler environments. A big complaint of older compact fluorescent lamps was that they took an excessively long time to warm up to usable brightness in the winter, making them impractical for outdoor...
