EcoSmart is a Home Depot 'in-store' Branded product. No different than when you shop at the supermarket and buy a can of store-brand tomato sauce. There may be a company named EcoSmart producing bulbs, but if you walk into any Home Depot store, you can see the Home Depot address/warranty and the like plastered all over the EcoSmart boxes. If EcoSmart was a private-label packaged product you would not see this. Yes, the EcoSmart branded bulbs were of superior quality (when they were produced by TCP) ~ so yes, you will find terrific ratings. However, as of a few months ago, the bulbs are no longer being manufactured by TCP ~ as witnessed by the lack of TCP logo and name and corresponding TCP model number on the bottom of both the box and the bulb.
Picked up Daylight, Soft White, Bright White LED Dimmable A19 (traditionally shaped bulbs) at Home Depot. No where on the box was the TCP logo (typically always at the bottom of the box). The base of the bulb is different than those sold through WalMart (for past years). The markings (numbers) and wattage mA are different and do not correspond to TCP (to my knowledge).
Would surmise TCP is not longer manufacturing this bulb (most common of all LEDs) under contract to Home Depot.
Am tempted to cut open the bulb to inspect the components/circuit board inside to compare to TCP's A19 sold through Walmart.
