* Lumen tests were performed by Luminaire Test Laboratory (LTL), one of the best testing labs in the United States. While LTL found the total lumens for a standard incandescent bulb to be higher, the Cool White GeoBulb® is about 25% brighter in the 0-90 degree quadrant which is one of the most important areas of usable light. The light output of the GeoBulb® was designed to point in primarily one direction based on our research of actual use.
