Q: Which colour lamp is best for tasks and reading and which colour is best for dining or just relaxing?
A: The daylight or soft daylight colour is best for tasks and reading or where you want to be able to see true colours. The soft white (warm white) is preferable where a soft warm light is needed, such as dining or general relaxing. The soft white lamps are similar in colour to an incandescent light.LED Corn E27 Lighting Bulbs 20W
Q: What ia LM79 ?
A: This IES document applies to LED fixtures (but not to components.) It prescribes the approved method for “Electrical and Photometric Measurements of Solid-State Lighting Products.” In the beginning, LED products were the wild, wild west. Manufacturers claimed just about anything based on their own personal “test procedures.” LM79 gave structure to the chaos and today LM79 compliance can help ensure that you are comparing apples to apples when you read LED product literature.LED Corn E27 Lighting Bulbs 20W
