Guide to Different Types of Lighting Bulbs
As festive seasons approach, many seek to brighten their homes and gardens with a variety of lighting options. Here’s a comprehensive overview of popular types of bulbs for different applications.
Standard Line Voltage (120 volts)
- PAR Series (16, 20, 30, 38)
Designed with reflector technology, these bulbs offer precise beam control and superior illumination. Ideal for outdoor floodlights and spotlighting. - T-3 Double-Ended
These bulbs are versatile and available in various bases, commonly used in sconces and floor lamps to provide indirect lighting. Their direction can be adjusted by the fixture. - T-4 Single-Ended
Available in mini-can and bayonet bases, these bulbs are perfect for sconces, pendants, and bath fixtures, offering effective indirect lighting.

They are also frequently employed for accent lighting in torchieres, wall sconces, pendant fixtures, and bathroom bars.
Low-Voltage (12-volt) Bulbs
- MR8, MR11, and MR16
Known as mini-reflector bulbs, these provide excellent beam control. Their compact size makes them suitable for small tracks and specific fixtures. - PAR36
Ideal for long-distance lighting, these bulbs are used in track, recessed, and landscape outdoor lighting applications. - T-4 Bi-Pin
Small in size, these are used in desk lamps, pendants, and low-voltage lighting systems.
They also find usage in under-cabinet lighting for kitchens and workspaces.
- Xenon
Featuring a sturdy loop festoon base, these resemble halogen bulbs but with longer lifespan. Emitting white light, they operate at lower temperatures and are common in under-cabinet and outdoor lighting. - Fluorescent Tubes
Utilizing an electric arc, these bulbs are energy-efficient, lasting up to 20 times longer than incandescent bulbs, with many color options available. They contain mercury and require proper disposal. - CFLs (Compact Fluorescent Lamps)
Small, versatile, and suitable for standard fixtures, CFLs are commonly used to replace traditional bulbs in homes and offices. - T8 Tubes
Typically used in large fixtures, these require electronic ballasts and provide instant start without noise, suitable for commercial and residential spaces. - HID (High-Intensity Discharge) Bulbs
Extremely durable, energy-efficient, and with long lifespans, they are mainly used in outdoor security and large-area lighting applications.
