About Brightness and Light Appearance

Find the right lumen level to brighten your space. Then, compare the way warm, neutral, and cool lighting affect the appearance of everyday objects.

Bi-Pin-Base Floodlight and Spotlight Bulbs

MR16 Bulb Shape

Often used in display and landscape lighting, these small bulbs produce a focused beam of light. Bulbs that are 50W or higher are often used in overhead projectors and microscopes. They’re brightest at the center of their beam angle; the edges of the beam are about half as bright. The narrower the beam, the more concentrated the light.

LED—LED bulbs last longer and are more efficient than halogen bulbs. They generate little heat and withstand vibration.

Plastic Bulb—Plastic LED bulbs are shatterproof.

Dim-to-Warm—Dim-to-warm bulbs mimic halogen bulbs—their light gets warmer as you dim them. They have museum-quality color accuracy, so colors appear as accurate and vibrant as they would in natural sunlight. They’re also flicker free and have lower levels of blue light than standard LEDs to reduce eyestrain.

Selectable Light Appearance—Bulbs with a selectable light appearance have a switch that lets you match other lights in your room.

Cannot Be Sold To—Bulbs that cannot be sold to the regions listed do not meet local energy efficiency requirements.

Any-Which-Way Workstation Lights


Style D		For Style D

Mount these lights to a workstation or dry machining center and use the flexible arm to position them close to your task. Also known as gooseneck-arm lights, they hold their shape once you bend them. They have a narrow head that won’t block your view of repairs, inspections, and other detail work.

Style D—Style D have the longest reach and the smallest head, so they stretch across large surfaces and squeeze into tight spots.
