Circular Light Bulbs & Lamps - Grainger Industrial Supply

LED typically lasts longer and uses less energy than other technologies. LED lamps reach full brightness instantly and produce very little heat.
Fluorescent is more energy efficient than incandescent but less energy efficient than LED. It produces less light output in hot environments and may hum or flicker.

Light Appearance

Light appearance describes the hue and tone of white that the lamp emits, which impacts the look and feel of a room.

Warm White (3000K & Under) has a yellowish hue and a soft tone for a relaxing and calming ambience in settings such as lobbies, restaurants, hotel rooms, and retail stores.
Cool White (4100 to 4900K) has a bluish-white hue and a crisp tone for clean and vibrant ambience in merchandise showrooms, hospitals, and parking garages.
Daylight (5000K & Above) has a blue hue and a sharp tone for an energizing and intense ambience in galleries, workshops, warehouses, and manufacturing facilities.

Color Temperature

Color temperature is a numeric value for the hue and tone of white that a light emits. Also known as correlated color temperature (CCT), it's measured on the degrees Kelvin (K) scale. Light at 3500K is neutral. Light below 3500K looks more yellow and is described as warm or soft white. Light above 3500K looks more blue and is described as cool white or daylight.

3000K
4100K
6200K

Light Output

The amount of light that a bulb produces as measured in lumens (lm). The higher the lumens, the brighter the light. Lumens, not watts, provide a basis for comparing the brightness of light bulbs. Watts measure a bulb's energy usage.

910 lm
1,050 lm
1,100 lm
1,150 lm
1,400 lm
1,800 lm
1,900 lm
1,950 lm
2,000 lm
2,500 lm

Color Rendering Index

Color Rendering Index (CRI) describes how accurately a light source shows color as compared to natural light. It's measured from 0 to 100 with 100 representing the most crisp, true-to-life color. Light sources with CRI in the 70s (typically outdoor lights) have fair color rendering. Light sources with CRI in the 80s (commonly used in offices) have good color rendering. Light sources with 85 to 90 CRI have very good color rendering for retail and display lighting. Light sources with 90 CRI or more have excellent color rendering for photo studios and production tasks requiring color differentiation.

Voltage

Voltage is the electrical power rating of the light bulb, which must be compatible with the voltage supplied to the bulb.

109V AC
230V AC
61V AC
84V AC

Shatter-Resistant

A shatter-resistant bulb is coated or made of materials that resist impacts and keep glass shards and contaminants contained if the bulb cracks or bursts, easing cleanup and reducing the risk of injuries.

Circular Light Bulbs & Lamps

Available10 products

Circular light bulbs emit a full circle of light for uniform distribution in general lighting applications. Also known as circline lamps, they supply the light source in fixtures such as drum-style ceiling lights, magnifier lights, and ceiling fan lights.

Circular Lamps

Circular lamps have a pin base that plugs into a matching socket on a compatible light fixture.
