Insignia is the house brand of Best Buy.  The LEDs used in the bulb are manufactured by Cree, one of the most reputable names in the LED business. The Insignia LED brand uses Cree LEDs to produce 800 Lumens in the 13-Watt version and 450 Lumens in the 9-Watt version. 

From the Cree website announcing the release of the Best Buy Insignia LED bulb:

"Powered by Cree, Inc. LEDs, the new bulb is designed with improved features to make adoption of LED lighting easier for consumers.  The Insignia LED bulb, available exclusively at Best Buy, was developed in partnership with local Twin Cities inventor Dave Carroll and offers distinct advantages over existing LED bulbs on the market today.

Unlike other LED bulbs, the Insignia LED light bulb looks like a traditional incandescent light bulb, a familiar bulb shape for consumers, and provides a more-ambient, omnidirectional light. Additionally, the bulb provides immediate full brightness when turned on, unlike CFL bulbs on the market, which require a “warm-up” period. Mercury- and gas-free, the Insignia LED light bulb avoids CFL toxic hazards and disposal hassles.

“It was important to me to create a LED bulb that would solve some of the current pain points for consumers,” said Dave Carroll, LED bulb inventor. “Consumers have traditionally resisted other high-efficiency light bulbs due to their unattractive shapes, strange lighting and high costs. Teaming with my Insignia partners at Best Buy and the lighting experts at Cree enabled me to bring a better-quality bulb to market at a more affordable price.”
