Bulb sizing is very straightforward and simple, it is based on the diameter of the bulb at its widest point, measured in eighths of an inch (⅛”). For example, the designation “T12” indicates a tubular bulb that is 12 eighths of an inch (12/8”) in diameter (or 1 ½”).
Likewise, What are different bulb sizes?
Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.
- A15 bulb: 15/8 = 1-7/8″ diameter.
- A19 bulb: 19/8 = 2-3/8″ diameter.
- A21 bulb: 21/8 = 2-5/8″ diameter.
- A25 bulb: 25/8 = 3-1/8″ diameter.
- G11 bulb: 11/8 = 1-3/8″ diameter.
- G14 bulb: 14/8 = 1-3/4″ diameter.
- G16/G50: 16/8 = 2″ diameter.

What happens if you put a 100 watt bulb in a 60 watt socket?
Putting a 100-watt bulb in a 60-watt fixture could cause intense heat, melting the light socket and the insulation on the fixture’s wires. Any time you have that kind of damage on wires, you’re at a big risk for arc faults, where an electrical current falls off its intended path— a leading cause of home fires.
What type of light bulb is closest to natural light?
Halogen bulbs are a type of incandescent that gives a close approximation of natural daylight, known as “white light.” Colors appear sharper under halogen light and the bulbs can be dimmed. They’re a little more energy efficient than incandescent bulbs, but they’re more expensive and burn at a higher temperature.
