What is a 9W bulb?
What is a 9W bulb?
The meaning of 9W=75W is that the LED lightbulb consumes only 9W of electric power to produce the same light output (luminous flux) as would be produced by a 75W tungsten-filament incandescent lightbulb.

What is the most energy efficient light bulb?
The most energy efficient light bulbs are compact fluorescent light bulbs, or CFLs, and LED bulbs. CFLs use mercury to cause a phosphor coating on the inside of the bulb of fluoresce, thereby producing light, while LED bulbs use light-emitting diodes as their light source.
Are E26 and A19 bulbs interchangeable?
Most homeowners would think that A19 bulbs and E26 bulbs are interchangeable . However, they are actually two different terminologies as a whole. That said, it is possible that an a19 bulb is same as e26 bulb, and it is possible that it is different.
What is A19 bulb type?
Physical outline. The most commonly used A-series light bulb type is the A19 bulb (or its metric/IEC equivalent, the A60 bulb), which is 19⁄ 8 in (2 3⁄ 8 in; 60 mm) wide at its widest point and approximately 4 3⁄ 8 inches (110 mm) in length.
What are energy saving light bulbs?
Energy saving lamps are sources of artificial light that employ advanced technology to reduce the amount of electricity used to generate light, relative to traditional filament-burning light bulbs. Examples of energy saving lamps include: Fluorescent lamps; i.e. regular and compact. a Light-emitting diode bulb.
