General lighting refers to the overall illumination provided in a space to create a uniformly lit environment. This type of lighting is designed to evenly distribute light throughout a room, establishing a comfortable level of brightness that supports daily activities. Unlike task lighting (which is focused, directional light for specific activities like reading or cooking) or accent lighting (which highlights particular features or areas for visual interest), general lighting serves as the foundational light source, reducing deep shadows and glare while creating a pleasant and functional atmosphere.

An external hard disk is a portable storage device that can be connected to a computer wirelessly or through a universal serial bus (USB) or high-definition multimedia interface (HDMI). External hard disks are frequently used to back up computers or serve as network drives since they have large storage capabilities.

Exfoliators and scrubs are skincare products designed to remove dead skin cells from the surface of the skin. They help unclog pores, improve skin texture, and promote cell turnover, leaving the skin smoother, brighter, and more radiant.

Event management as a service market refers to cloud-based platforms and solutions that enable planning, organizing, executing, and analyzing events. It offers tools for registration, ticketing, marketing, attendee engagement, and analytics, helping organizations streamline event operations and enhance user experiences across virtual, hybrid, and in-person formats.

E-textiles, also known as smart textiles or interactive textiles, are integrated with electronic components such as sensors for different applications in heat management, health monitoring, illumination, communication, sensing, and other related uses. Smart textiles are available in the wearable form of gloves, coats, T-shirts, and sportswear, which are further connected with smartphones, trackers, and entertainment devices.

In glass recycling, waste glasses are crushed and melted to cullet. Cullet is a high-grade product that is mixed with virgin materials such as sand and limestone for manufacturing new glass bottles and containers. This cullet can be further categorized into internal and external cullet based on the feedstock used for manufacturing. The internal cullet is manufactured by crushing defective glass products such as bottles, which are rejected during a quality check at various manufacturing industries. The external cullet is manufactured by the processing of used bottles or other glass. Glass fines are low-grade products, which are used in the manufacturing mix of construction and car glass.

A glass lens is a transparent optical component used in glasses (eyewear) to correct vision or protect the eyes. These lenses can be made from various materials, including glass, plastic, or polycarbonate, and are designed to focus light correctly onto the retina, helping to improve vision clarity.

Diesel exhaust fluid (DEF) is a blended aqueous solution composed of 32.5% high-purity urea and 67.5% deionized water. It acts as a reactant for the functioning of the selective catalytic reduction (SCR) system, an advanced active emission control technology system. DEF is standardized as aqueous urea solution (AUS) 32 in ISO 22241. AUS 32 is registered as a trademark AdBlue by the German Association of the Automotive Industry (VDA).

A concrete pump is a construction machine used to transfer liquid concrete efficiently from a mixing truck to the desired location on a job site. It uses hydraulic pressure to deliver concrete through pipes or hoses, enabling precise placement in hard-to-reach areas such as high-rise buildings, tunnels, or large slabs. Concrete pumps are essential for modern construction projects due to their speed, accuracy, and reduced labor requirements compared to manual pouring methods.

Digit joint implants are used to replace damaged or diseased joints and bones in people with osteoarthritis (OA) and rheumatoid arthritis (RA). These implants are attached to the affected parts of patients during arthroplasty surgery to restore the function and structure of the digits in the fingers (hands) and toes (feet).
