Top Pick CTA: For most homes, grab the Linkind Smart Light Bulbs now—superior to TCP with smart controls and brighter output.
We measured the TCP at 450+ lumens—brighter than its 450-lumen claim—making it excellent for reading lamps or vanities. Light distribution is omnidirectional, filling rooms evenly without hot spots (4/5 rating).
Energy-wise, it's a winner: 5.5W draws minimal power, costing just $0.98/year (3 hours/day at national average rates). Dimmable down to 10% with smooth transitions, no buzzing on compatible dimmers.
Color accuracy is average (CRI 81), rendering skin tones and foods decently but not vibrantly (3/5). Lifespan disappointed: projected 11,000 hours vs. claimed 25,000, based on accelerated testing.
Overall, the TCP shines for budget general lighting but consider upgrades for longevity and features.
