Design and Build Quality
The bulb uses a patented ceramic heat sink instead of a traditional Mcpcb aluminum substrate, which SANSI states reduces thermal resistance between the LED chips and the heat sink surface for better reliability.
It measures 4.96 inches tall and 3.03 inches in diameter, larger than a standard A21 bulb, and weighs about 0.6 pounds. The lamp body is rated to flame retardant grade V0 and anti-corrosion grade WF2.
Performance in Everyday Use
