The necessity of DTC stems from the limitations of traditional diffusion models and personalization-driven models. While former models excel in capturing world models, they often falter in preserving product details. On the other hand, personalization models maintain item fidelity but are not optimized for…

1.1  These requirements cover LED equipment that is an integral part of LED luminaires or lighting systems. These requirements cover LED drivers, controllers, arrays (modules), and packages as defined within this standard. These requirements also cover power sources that are integrated into LED luminaires or lighting systems for functions other than a LED driver (e.g., DALI bus power supply).

UL 8750 was originally licensed in Canada to CSA to be used as the base standard for CSA C22.2 No. 250.13.  CSA has relinquished the rights of the CSA C22.2 No. 250.13 back to UL Standards & Engagement for publication in Canada as of December 2023 via copyright termination agreement. ULSE intends to publish a joint standard for the US and Canada, and CSA has agreed to withdraw their standard following publication in a reasonable timeframe to ensure there are no gaps or loss of coverage for manufacturer's products that are currently certified to the CSA standard.

1.3  LED equipment is utilized in lighting products that comply with the end-product standards listed below. The requirements in this standard are intended to supplement those in other end-product standards.

Note: The information provided above was obtained by the Standards Council of Canada (SCC) and is provided as part of a centralized, transparent notification system for new standards development. The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.

1.4  The requirements in this standard do not anticipate additional construction, performance and marking considerations for the following end-applications: LED equipment subject to weather (outdoor use), LED equipment installed in air handling spaces or in other environmental air spaces (plenums), LED equipment intended for Emergency Lighting and Power Equipment, LED equipment with integral batteries (and battery packs), and LED equipment used in fire rated installations. LED equipment with such end-applications is subject to additional evaluation per applicable standards.

1.2  These lighting products are intended for installation on branch circuits of 600 V nominal or less in accordance with the National Electrical Code (NEC), ANSI/NFPA 70, and for connection to isolated (non-utility connected) power sources such as generators, batteries, fuel cells, solar cells, and the like.

In the evolving landscape of online shopping, the “Diffuse to Choose” (DTC) model emerges as a groundbreaking advancement in virtual try-all experiences. This model enriches image-conditioned inpainting in latent diffusion models, allowing users to seamlessly integrate e-commerce products into any setting. Developed by a team at Amazon, DTC represents a significant leap in virtual shopping, combining the efficiency of diffusion-based models with the precision of image conditioning.

1.1.0  LED equipment covered by this standard are intended for operation in the visible light spectrum between 400 – 700 nm. Coherent light sources (e.g. laser sources) are not covered by this standard.
