Wattage is the energy consumed by light every hour.
In the same family of bulbs (
Like an incandescent lamp.
The higher the wattage, the brighter the light.
The downside is that you use more energy.
So, if a bulb is 100 watts, you use 100 watts of energy per hour.
You will often see this abbreviation, and you will see that the abbreviation is as follows: 100 W or 100 w.
This number will be more like 16 w if you are using compact fluorescent.
For example, the bulb shape with Philips Lighting, there are at least 50 bulb shapes in the incandescent lamp.
With halogen lamps and halogen lamps, you will find that there are at least 32 bulb shapes.
In the Philips fluorescent and compact fluorescent groups, there are at least 38 bulb shapes.
Finally, HID, Specialty and LED bulbs have more than 50 bulb shapes.
If you use PAR38 in embedded lighting, incandescent, halogen, compact fluorescent or metal halogen lamps also have the same bulb shape.
The total length of the bulb may vary, but the basic shape of the bulb will be the same.
How do you know what shape your bulb is?
The letters used are not really abbreviations.
Examples of bulb shapes: BT15, BR40, PAR38, T4, G25, A19, etc.

Low-voltage lighting is 12 volts or 12 volts, usually halogen lamps.
The spotlights and floodlights or floodlights that are often used in recessed tanks have different degrees of light. It might be 10(degrees)
, 25, 32 or 40 or any number in this range.
