This AC LED bulb has an iconic form and 4 mm plated body shape. It provides omni-directional light distribution just like an incandescent bulb. Our company's HV-AC chip, the world’s leading high-quality AC LED package, has been integrated. It does not require a PSU (power supply unit) that is so often a nuisance with other LED bulbs. The Essence's silhouette changes into completely different shapes depending on the angle of the heat sink plate. By arranging the AC LEDs opposite each other, light distribution is omni-directional like an incandescent bulb. The removal of the PSU has made the Essence ultra-slim and ultra-lightweight.
