Who makes EcoSmart bulbs?

EcoSmart bulbs are a private-label brand owned by The Home Depot, and they are made by contracted original equipment manufacturers under Home Depot's specifications, rather than by Home Depot itself. Home Depot does not own bulb factories; instead it designs the requirements for brightness, color temperature, energy efficiency, and safety certifications, and then hires large lighting manufacturers to produce them. The main manufacturers have historically included Leedarson Lighting, one of the largest LED bulb makers in the world based in China, as well as other major ODM factories like Cree and other Chinese suppliers. The exact factory can vary by product line and year depending on contracts, but all must meet UL or ETL safety listings and Energy Star requirements set by Home Depot. This private-label model is similar to how Costco's Kirkland brand or Walmart's Great Value brand works: the retailer owns the brand name and controls quality and warranty, while production is outsourced. The bulbs are then packaged as EcoSmart and sold exclusively at Home Depot stores and homedepot.com. Home Depot provides the warranty, typically 3 to 5 years, and handles customer support, even though the physical assembly occurs overseas.
