Miniature LED Adjustable-Arm Lights
Though not as bright as our miniature fiber-optic lights, these lights have built-in LEDs that last longer, are more efficient, and are more affordable. Use them to illuminate small and microscopic parts. They cast cool light that highlights white/blue tones, which is good for inspecting.

Circline Tubular Light Bulbs
Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are often used in workspaces. Bulbs with a cool light appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh. They contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).
