Home Depot offers the TCP 65-watt Equivalent Soft White Dimmable LED Retrofit Downlight, model no. RL12DR6527K, for $15.88. Opt for ship-to-store pickup to dodge the $5.99 shipping fee. That's the lowest total price we could find by $9. (We saw a 2-pack for $28 shipped three weeks ago.) It features a brightness of 650 lumens and a purported lifespan of 32 years.
